HSDPA, will donate for help!!

Hi guys, i know this is a common problem amongst some of us, there are several threads discussing the connection drops but please there must be someone out there who knows something about it.
Basically with HSDPA enabled, the connection will last a random period of time before disconnecting by itself and displaying: cannot connect for an unknown reason.
When HSDPA is turned off, only 3G is used, although this works fine, it is fairly slower.
I am on T-Mobile UK, I have phoned their technical support, we have established it is not the sim card but the phone itself and have tried a variety of steps to solve this, for example receiving band settings for WCDMA, this has not fixed the problem.
I have tried changing the username and password combinations and have tried every combination of every advanced network option. I have used the T-Mobile stock rom 1.43, official HTC ROM 1.66, duttys hg, energyROM, artemis 5.0 and artemis 5.5 (would recommend btw) using MTTY before every flash, and every single different radio combination.
Myself, and many people here would be very grateful for any help posted.
Thanks in advance

Why don't you try Settings > Connections > Advanced network > GPRS tab > change from PAP to CHAP.. and reset... or viceversa.. that helped for me..

Thanks for the post, i've tried all that i've tried all advanced settings, at most they last for a day or so but after a while the connection dropouts seem to worsen

Ok ive just gotten off the phone for the third time with the technical support
basically what they've said is that the hsdpa WILL disconnect because the mobile towers simply can't handle the traffic.
He said in his honest opinion I should disable it because it simply won't work well and there is no fix.
Taking the piss juuuuust a little bit

Mine on t-mobile uk will show H, but usually drop down to 3G. It won't give me an error when it drops down though.
It sounds like its not transferring from H to 3G.
To be honest, i was unaware t-mobile ran HSDPA till I got my HD2 (never showed on my BB).

mine switches between 3G and H too, this happens when the connection is being used (for example loading a web page) when the job is finished (page has finished loading) it turns back to 3G right?
are you saying that your connection never disconnects?
may i ask which radio and rom you are using?
thanks!

For my personal experience, I have for over a month, on versions 1.48, 1.66 by HTC, artemis versions, versions of other French chefs. had no problems,
Login Exchange push 24/24 without any cuts, I solicited the network with opera I passed automatically 3g H, and since February it to completely fall with the problems that everyone encounters (lost connection for several minutes , unable to connect to 3G without hard reset)
to remove the sim chip, I try with another chip of the same operator, another chip from another operator, the problem is still there.
For several days I have also continued a Touch HD, it faces no problems, no problems in connection 24/24.
In short, impossible to challenge any operator, any base station, any sim card.
It is then that the problem come from HD2:
-Software: We all try every combination of rom and radio rom possible.
It is the hardware, maybe the chip integrated into a concern for design, manufacturing concerns on some series, may be dysfunctional due to incompatibilitée between several chips of the phone, short, HTC should look into the problem.

correct, it never disconnects.
It will switch seemlessly between them, when using or not using.
same one it came with. O2 HD2.
ROM 1.43.206.4 (70315) WWE
RADIO 2.04.50.22_2

I've also been struggling with this problem ever since I got my HD2 three weeks ago. However it seems like only a few people experience this.
My case is exactly like cgrec92 described. I'm on a 3.5G network in Denmark (3 Mobile), the phone shows the 3G connection at all times. When things do work and I use Opera/weather/Twitter/email etc, the symbol changes to H and I know the data connection is functioning. I can be using this for a whole hour without any problems.
However, if I put the phone down for a while and then pick it up again to use one of its data services, very often it does not connect to 3.5G (or H) anymore. It will still show the 3G icon on the screen, but there's no data connection. Then I go to Connection Manager and I can see that data connection shows as Off - and after a few seconds it goes back to On by itself That does not mean the problem is solved, as the phone still fails to establish any data connection. What I need to do then is manually turn off data connection and re-enable it again, which makes the 3G symbol immediately change to H. Then everything starts working again - until the next time it stops working...
I contacted the HTC customer service and they said it might be a driver-related issue, recommended a hard reset. I did that and for a few hours I thought it solved the problem, but no, data connection still disconnects by itself.
I spoke to 3 Mobile's technical service and they told me to update my software, which I had already done previously (I'm running stock 1.66 ROM Danish). They also said they never received any such complains about the HD2.
Like cgrec92 I've also played with all kinds of network/band settings, but it did not make any difference.
***
One question: isn't the phone supposed to automatically connect via EDGE when it cannot connect via HSDPA? Because in my case it will only establish data connection via H, never EDGE.
Any advice is greatly appreciated!

My take on this FWIW
It's not the phone!
It's the radio ROM installed.
I live in an an area where T-mobile say I can't get HSDPA.
However, I know that I can. How? Because 3 network uses the same local cell and transmitter as T-mobile and their signal will rip your eyes out!!!!!!!!!
All information obtained from a good friend of mine who works for BT, who, service manage the cells for the networks.
Plus, in this location, the cell traffic is then handled by BTs digiatal backbone which takes it who knows where after that.
So I have a very isolated situation in which I know there is a decent HSDPA signal, but I have had trouble with drop outs on my two previous phones (Nokis 5800 and HTC Touch Diamond 2) and originally on my two T-mobile mobile broadband feeds using Huawei E220 cell network modems.
All fixed when I finally found the right Radio and flashed it on the phones and unlocked and flashed the latest modem firmware.
My broadband connections are always on and never drop out and my HSDPA signal on my HD2 is through the roof!
To further emphasise the point all the equipment is used (when home based) behind solar glass which is notorious for blocking mobile phone signals.
Land on the best one and you will get incresed battery life as well.
Bottom line is try the latest radios (2.08.50.08_02 in my case) and I think you may be surprised at the results.

I have the same problem with the connection dropping. What I did to make it work was to disable HDSPA and putting GPRS to CHAP instead of PAP, and so far I have no problems at all

Thanks for the reply and tips. I also did the same earlier today, except that I did not change PAP to CHAP :O. I was waiting until tomorrow before I posted any results, but I gotta say so far the connection has been stable just like yours.
I also called HTC's customer service in Denmark and the fellow I spoke to was very helpful but he said he has never heard about such problems. He sent me updated network settings via sms, but it did not fix the problem.
I mean, only some users around the world suffer from this problem, right? So what is it that's wrong with our devices? Is it a production fault? If I exchange my phone for a brand new one maybe I won't be unlucky again? When 3 DK finally told you the problem was unfixable, did they mention other users with the same issue? Did they ever offer to replace your phone?

Erm!
It's your radio!
But, I think I did say that in a previous post.
You had a helpful fellow who sent you updated settings?
And he thought that was going to fix your problem?
That was helpful!
It's your radio!
The technicalities are beyond a customer assistant at the end of a phone. They work from a script.
I'll send you the settings.
Have you done this?
Have you done that ?
Never heard of anyone else with your problem!
It's your radio!
T-mobile uses PAP protocol (at least they do here in the UK) and it's a handshake protocol so changing that won't really do anything to the signal definition.
You have it or you don't.
It's your radio!
There is no "production fault".
You are not "lucky" or "unlucky".
You are in an area where you will suffer from this because of the ???????
THE RADIO!
I think I have made my point.
If it turns out that you don't have a radio issue then please feel free to admonish me.
Until then----------
It's your radio!

well I don't mean to sound rude but do you SERIOUSLY think we haven't tried that? ive tried every possible radio available here and every different rom, so excuse us for trying new things.im glad your not having any troubles yourself because it is really annoying
perhaps you could post us your rom and radio?
I don't suppose you could post us your settings in advanced network?
did you use the connection setup?
thanks for your help

Yes, I was about to mention something similar. I haven't tried combining different ROMS & Radios myself, but I know people like cgrec92 who have with no good results.
And if it is the radio, then every 3 Denmark user like me would be experiencing the same problem, correct? I don't think that's the case. Actually when you read the forums you will find users from different countries with this problem, and they/we are not the only ones with a certain combination of ROM/Radio.
So yes, by disabling HDSPA I finally managed to have a stable data connection (but no 3.5G, obviously). At this point no one seems to know the cause of this issue, but I suppose it's naive to expect a future ROM to solve it, after all it's not a widespread problem. Is HTC even working on it? Are we sure it's not our devices that are faulty?
I honestly have no idea, but I cannot just accept this problem and live with it after all the money I put into this phone. That's why I brought up the possibility of having it exchanged for a brand new one in hopes that it will not have this problem.
Any ideas?

I referred to my radio in my previous post -20.08.50.08_02.
My OS ROM is Leo Lite 3.
Connection setup used and no further settings.
My explanation for this is the fringe nature of the received signal.
The radio its constantly 'hunting' for a signal and the radio software has difficulty in locking on.
BTW OS ROM and settings ready don't affect the efficiency of the radio signal.

I appreciate the help, but he doesn't seem to understand the issue here. It's not that we have low connection, or that we cannot connect to the 3.5G network. The problem is that the phone's data connection will automatically disconnect even when we are in an area with full 3.5G signal. The phone will connect for a while and then, moments later, in the same spot and with full signal, data connection is terminated. So I just can't see how the radio has anything to do with that, especially when there are hundreds of other users out there with the same ROM & Radio as us and in the same network. And yet they do not experience this problem.

Ive have similar issues but it depends where i am it appears that some towers its ok where others its not!

The radio differentiates between all the different levels and types of signal and it depends on how exact it interprets the signal. They are supposedly optimized before release and then re optimized with each newly released version. Network operators then have their own network parameters and again the radio has to accommodate this as well. One radio will never satisfy all these criteria and some of you will be in the wrong place at the wrong time on the wrong network with the least effective radio.
I can assure you that I most certainly do understand the problem and that is why, in my own case, I have resolved it.

Gsm signal issue

I have my sgs for 2 weeks now. GSM disconnects around every 2 days.
At service mode (*#*#4636#*#* - Phone information) i can see this repport:
GSM disconnects:
====DATA=====
State: inactive
disconnected with last try
at 00:59
fail because No Error
The question is: why does this happen?
Is this an android issue or a hardware problem?
Any pointers?
Thanks in advance
.

do you ever enter a building, subway, or some other location where the GSM becomes poor?

That's not the problem.
Gsm disconnects just like that ,at home for instance. And when I notice that and try to reconnect (settings- wireless networks- mobile networks - networks operators) it doesnt find ANY of them.
Then I restart the phone and gsm network is back.
If I dont notice disconnection in time (so I can restart phone, people just cannot reach me....quite frustrating...

i see what you mean now.
yes, i've noticed that on mine too, but.... that's because i was fooling around with some new Apps Widgets settings i was testing to control the radio and data to save battery.
Did you install any new Apps recently that might cause that?

Well I installed all kind of apps. but i have the feeling this problem was happening even before that.
And I dont need widgets to control data ( I think) because I set the sgs to use 2g networks only and I dont have apn configured( section is empty. Internet connec. only via wifi.

Well, my sim card is VERY old (2002) and the carrier (Telfort) is roaming into another carrier's network (Kpn) with no extra costs of course like real roaming, but still roaming (I get the little "R" next to the signal strenght bars)
Anyway this never happened with the Nokia 5800xm running Symbian OS and using the same sim card...
Starting to get pissed of with Android...
With Symbian you hack or root or tweak because you want to, not because you NEED to like with Android....
And then you prob. get side effects...
Thank you guys for your time

I would get a new sim card if I were you. Every android phone that I have had seems to work better with a good 3g sim.

Get a new SIM card.

same problem, different phone
i have the same problem on kaiser with flashed android on it.
sim is 2 years old, and now suddenly this happened, tried differents sim cards, but the problem persists. My guess is, it is a software problem.
Maybe i will report when I flash original WM6.1 rom onto it, if you are interested in the result
btw, this happened about two days ago and because of this im buying galaxy s so i hope the problem will be gone with new phone

Why you think the problem will be gone if it's still android and I also got it with my sgs? Or are you counting on Froyo?
Yesterday I upgraded my sgs to froyo jpc with kies. I am new with Android but the post of Aery was so clear that i didnt resist: http://forum.xda-developers.com/showthread.php?t=769400&highlight=froyo+upgrade
I did get stuck on reboot but could get out of it after applying a cache/data/factory reset on recovery mode (3 buttons)
Now I am being carefull with the 3rd party apps., and so far so good, no gsm disconnections .
Froyo is of course better that eclair but Android is still disappointing to me.
You flashed Android onto a WM device (i'm impressed); could you not teach me how to flash Symbian onto my SGS?
Voice dialing (over bluetooth or not) and proper connectivity control (network, data, gps and bluetooth) of android is years behind Symbian; and such a well written, light OS, it will just fly on a high-end hardware like the sgs; but that is an issue for another thread.http://forum.xda-developers.com/showthread.php?p=7938430#post7938430

I think indeed that's not the same issue. My problem is that the radio signal get turned off during inactivity. That's why I got connection back after reboot: radio signal gets turned on again; later I learned how to turn radio signal back on without rebooting, but that is just a remedy , no real solution.
Try to upgrade to froyo, make a factory reset and be carefull with 3rd party apps. With froyo you will need less interfering tools anyway
I dont thing that my old sim card is the problem, but i'll try to replace it anyway...but first things first
Btw dou you have 3g turned on? Cause I never...
Another mistery: When I have 3G on I see those bars (signal strenght) dancing and that "death grip" thing happening:http://www.youtube.com/watch?v=LROTHrTR92k
But when I have it on 2G only the bars doesnt move even if I strangle it with both hands.....
Please repport later how it's going...

I had the same issue, i sent mine back and got my money back, i had also tried with different simcards and resets and nothing worked.. so hopefully my new galaxy wont have this problem. Its strange that these problems are so rare though.. But as long i get it going ill be a happy man.

fourth day with JPC ( and 4 days after a factory reset) so far so good no disconnections . I think problem is gone...
Today just to be safe, I got a new sim card....the other one was too old anyway(8 years)

i have the same issue, for a few days i can't get 3g. i'm seriously wondering about sending back my sgs. i've ttried all the settings, changed my sim..nothing...begin to think it was a fullish thing to change Desire to SGS..

Well... this is not the same issue.
I have 3G (WCDMA) disabled. I only use 2G (GSM) and WIFI for data/internet connection.
I Dont have a data account, I dont need it therefore I disabled 3G in order to save battery.
If you do want to use 3G, just go to settings - wireless and network - mobile network settings - network mode and set auto-mode (GSM/WCDMA or 3G/2G)
If it doesn't work, apply a data/factory reset and try again.
And if it doesnt work, it's probably hardware related and you should return it or send it for repair.
My issue is more complicated; next to the fact that I dont want to use 3g, my carrier is roaming to another network and probably Android OS or the firmware cannot handle it properly.
Android is still premature and the "Samsung - Android integration" seems to need a lot of development as well.
It is just a shame that basic functions like proper connectivity control just wont cut it. And Google is not doing any good either.
And dont let me get started on the voice recognition issue......
Hardwarewise, the SGS is superior that htc desire.....I wonder how it would perform if running Symbian^3 OS or Meego.....
I get a great sound quality from the stock music player just by mixing the equalizer and using the music clarity effect...just great...better than any other device I tried.
And the OFFLINE Gps experience is just great as well: the combination SGS - Motonav - External Bluetooth gps device is working like a charm.
I wouldn't change my sgs just yet......

yesterday i was swiching sims to determine if is a sim fault and suddenly i have my 3g/h back. happy owner again. i've tried all to do this, from firmware upgrade to servide mode settings..i don't know why but i'm ok again...

Hello,
I know its been a long time since you wrote this thread but I just came by it!
I have the exact same problem with you (I had it since August) even now with the official froyo. I tried factory reset and no new apps (that could cause the problem) but it still disconnects randomly in GSM mode. However, when I have it on auto (gsm and wcdma) I have no issues. I just disconnect data from the power button in froyo. I am wondering if you ever found a solution..
Chryssa

Well, I am subscribed to this topic so I saw your post.
Good and bad news:
First the bad one: No solution yet, it keeps disconnecting IF I stay on "gsm only".
And the good (or a little better) news:
I noticed that on sgs, using "gsm only" or "gsm/wcdma (auto mode) makes no difference on battery consumption....
By the way, this is a Samsung issue, not really an Android one.
On a HTC Desire HD, you can use "gsm only" mode with no problems...

Thank you for your answer!
I noticed that about the battery too. So not too bad, I just have to keep it on auto mode then..

Same issue
Im having the same issue but in a optimus t the worst part is that i cant get service at all.. when i press change network preferred it wont change and when i try to press on turn on radio it wont work either....

[Q] Low Phone Signal

I have strange issue with phone signal
it started week ago, it is almost lost all the time.
I'm using CLK with different ROMS starting from Typhoon to Tytung Nexus HD2 GB to Qualiza ARA DHD 1.2
my Phone is TMOUS with radio 2.15....
I have tried to replace sim card but no luck,
any clue about this issue, is it because i'm changing the ROMs frequently?
Note: it doesn't matter if the settings are set for 3G or 2G.
always low to none signal.

I have the same problem with and without flash (windows to android) -_- ! (Radio 2.15.50.14)
Yesterday I buy a new cover on ebay, I will try this :

i hav a problem with m 3G speed i successfully install the wp7rom by XBmod-Yuki(HD2_Updatable_v2_nativ) and it was working flawless, i have not update it, i was using 7004 build only, while surfing for 15min i noticed that the back side is heated up too much(at this point of time my 3G speed is amazing...no problem at all). so i decided to go back to stock wm6.5(flash via sd card) and i found that i loose my 3G speed.... my hd2 shows that it is connected with 3g data pack("H" icon on top) but it gives the the surfing and downloading speed of GPRS only.
I tried several WM and Android builds but my hd2 is not ready to give me speed of 3G. i did task29(provided by doloop). i again flash the wp7 rom by Hd2Owner (http://forum.xda-developers.com/showthread.php?t=953078). still having same problem....
Plz help me out. any further information is needed to be provided???

Not much of a suggestion for you maybe but..
Contact your provider and see if your SIM is 3G compatible. Many people are using older SIMs which do not use the phones capabilities to the full. They should replace it for free. At least find out if there have been 3G problems in your area.
BTW the overheating you mentioned using 7004 may be due to bad SD drivers which are present in versions below 7392, upgrading might have helped cure this.
I hope this helps

1) Previously i was using the same sim card with 3G in the same location
where i am staying now.
2)w7 build of hd2owner is 7.5 only.

today i connect my mobile with my laptop(win XP) to use the internet and the local area connection shows 425mbps speed in status?? when i checked the speed on speedtest.net it shows 104kbps. while downloading a file the speed was 15 kbps.
any suggestion what to do?

is it a hardware related problem???

[Q] HD2 freezing with mobile data use across multiple ROMS. Any ideas?

So my T-Mobile HD2 is freezing up completely (necessitating battery pull) within a minute or two of turning on and using mobile data. Like the title says, it's happening on both ICS and Gingerbread ROMS.
HSPL 2.08
Radio 2.15.50.14
MAGLDR 1.13
CWM 3.0.0.5
Current ROM: Langthang's HD2 NDT MIUI STABLE VERSION 6.0
(http://forum.xda-developers.com/showthread.php?t=1010498)
Previous ROM: NexusHD2-ICS-CM9-HWA_V2.0
(http://forum.xda-developers.com/showthread.php?t=1434860)
Both ROMS run well (esp. the current one) except for the mobile data.
I've had the phone for about 16 months. When I first got it in the USA, I didn't trust myself to flash it to Android for the first time, so I had someone else knowledgeable put a Froyo ROM on it. So I can't tell you what version of HSPL he used to flash 2.08 to it. The phone worked fine (except for occasional overheating--it's an HD2, right?), including mobile data. This was in the USA.
Then I moved to Thailand where I didn't use mobile data at all for a long time. Last month I flashed over the old Froyo with the two ROMS (clean install) listed above and have started using mobile data for the first time in Thailand and am now noticing this problem.
More info:
1. Turning mobile data on and not actually using it actively (i.e. just letting whatever few Google things auto-sync in the background) will have it freezing within half an hour. Using it actively will have it freezing in 1-2 minutes.
2. Using a CPU governor (No-frills CPU control) set to the most extreme (“powersave”) keeps it from freezing up the phone for only a little bit longer than having it set to “performance,” so I don’t see the point in using that as a workaround.
I can guess what most people are going to say at this point: dude, you got one of the HD2′s with a hardware overheating problem; sorry, buy a new phone. Well, can’t afford to for a couple months so I’ve been trying to solve it in other ways. And anyway, I’ve stress-tested it with everything but mobile data (heavy use of camera, playing music, videos, and wifi) and no problems. Sure, it sometimes gets warm and might crash very occasionally...but no problems I can't live with.
So why in the name of all that is holy does using mobile data ALWAYS freeze it?
1. Would flashing a different radio conceivably help? Maybe because a different radio would work better with my carrier here in Thailand? (I know, you have to be careful that your radio is compatible with your ROM, else you brick phone. Also, I don't want to flash radio unless I absolutely have to because it's dangerous-ish).
2. Is HSPL version an issue?
3. Could it be my APN settings? Entering the info (minus the DNS stuff; don't know where that goes) from the following site (http://www.flexispy.com/globalapn.htm) stops mobile data from working at all. My carrier is AIS in Thailand.
Anyone who can help me, it's much appreciated. Thanks in advance!

HSPL fine & radio should be ok but was not best for me in asia but not due to overheating of device ...
Do the fridge test, keep it in fridge for 1hr in plastic bag to protect from moisture then activate data & see how it performs, keep it in fridge as much as possible or cool as possible with aircon, fan or ice bed ...
If you get lot longer times before freezing you can be 100% sure it related to heat & mainboard bga failure under heat.
Thailand is very hot and running temps of phones & notebooks are a lot higher here so a weakness is more easily reached ...
As you say you already have experienced overheating I would assume your mainboard is a bit more sensative to heat than most, we have over 20 HD2s in company use & in over 2yrs only 1 handset has had freezing issues & was mainboard BGA issue & new mainboard fixed it.
I would assume the the functioning of data produces more heat in term of cpu, radio stack & battery in a way that heat soaks the device to failure, I would of thought HQ video playback & heavy wifi use could see same fault so some more stress testing may be an idea too.
you on AIS 3G ?
You could try radio in my signature, I have used it in Thailand & asia pacific with great success so maybe worth a try !

I've done a little fridge testing and it does seem able to function on mobile data without freezing up. So obviously my phone's more sensitive than average to overheating (and also because of Thailand's heat), but I still wonder if using a different radio would work better and maybe not push my phone "over the edge."
One reason I still think there might be something wrong with the radio version is that I can never get 3G (only EDGE), even in places where I absolutely KNOW there's coverage. The other reason that makes me suspect the radio is the stress-testing I was talking about before. I tried really hard to make my phone overheat with a lot of processor-intensive stuff and I couldn't.
I really don't want to beat a dead horse, but does anyone else have any opinions or ideas before I mess with flashing a different radio?

P.S. Thanks for the link to your radio, Mister B.

IMO Mr. B is right about overheating motherboard, but couldn't harm anyone to flash another radio version.
Even I'm reservated on this, I wish you GOOD LUCK!

No 3G: Is 3g enabled in phone settings ?, is 3G enabled on your AIS sim card account ?
Trying another radio will do no harm & may help as might using the least resource hungry ROMs ... Android is a power hungry bulk of an OS & most mainboard faults only appear on Android or are worse on android ...
I have same TMOUS HD2 & 3G works fine here so no issues with phone Radios bands as many worry about ...

Mister B,
After writing that huge long post...I might be an idiot.
3g was enabled in my Android settings, but I didn't know it had to be enabled on the sim card. I'll go to a phone shop tomorrow and ask them about it.
Thanks everyone for their advice.

I not know who the idiot but worth checking as I believe if not buying a sim packaged as 3G you do not get 3G without getting account upgrade .
Confirmation either way will be useful ...
Unfortunately AIS website is a very good example on how to have a huge amount of content & over complex account types but absolutely no easy to find useful clear facts ...

Mister B,
1. Went to a phone shop and explained my problem. The guy there told me that he didn't think my phone was compatible with AIS' 3G band...but you have working 3G in Thailand with a T-Mobile HD2. Is your carrier TOT Mobile? Xda won't let me post outside links yet because I'm new, but I looked up the specs on the T-Mobile HD2 and on Thailand's mobile phone bands and it looks like the only carrier the T-Mobile HD2 can use 3g on is TOT Mobile (only carrier with either a 1700 or 2100 band).
2. Also, when I first got my SIM card here last year, I got a regular one, not a 3G one. The way I signed up for 3G was just by looking up and texting a code to AIS to subscribe to 3G service. I thought that was all I had to do. It seemed to work, except for only being able to get 2G. (I'm in Chiang Mai, and I know AIS has good 3G coverage here; I've experimented using my phone all over the city, but no 3G). So it looks like you're right in your last post about needing a 3G SIM card or an account upgrade.
Thanks again for your all your help. Would you mind confirming that your carrier is actually TOT Mobile? It would help me troubleshoot.

I use TOT for 3G (iKool) & DTAC for 2G Edge.
I thought AIS had license for 2100MHz 3G but if on 900MHz then will not work on AIS until upgrade there network.
Thailands 3G is a bit of a bodge effort until licensing is approved.
I would assume your current sim is not at fault & if you activated 3G via sms code it should be 3G active & just the current band being the limitation ...
How I wish 3 network would come to Thailand, their HK network is superb ...
