htc band settings on 3 network!?

Hi.
I have an HTC Touch HD on the UK 3 Network.
It works fine with texts and calls n 3g but whenever I need data for an app etc it ignores a great 3g signal and tries to connect on HSDPA instead.
now this might not seem like a problem but it often switches from full 3G bars to one bar on HSDPA to check my email. this can take 5 to 10 seconds when it could have just done it on 3G.
what gives? am i using the right settings?
start/settings/phone/band
Network Type "Auto"
GSM/UMTS band "Auto"
when i was on Vodafone it would stay on the best choice ie HSDPA instead of all this swapping about.
I hope this is the right place to ask. not a major problem just a frustration.
thanks

In common with many (all?) of the five networks, 3UK has recently switched their handsets from staying on HDSPA to "only" 3g, but automatically changing to HSDPA when data traffic occurs.
HSDPA demands extra bandwidth to the cell. There might be a second or so delay while the handset re-negotiates the extra protocol, but it's done to give extra capacity on the cell, allowing more space for 3G voice calls, while ensuting your data speeds aren't affected by push-email or similar low-bandwidth devices using an always-on HSDPA protocol.
In short, it's completly normal and pretty standard nowadays. Keep your phone on Auto/3G, you can't force it to HSDPA only.

Fix/Workaround for mobile data connectivity problems (3G/H/H+ dropping connection)

I've been following the mobile data connectivity issue that some users are experiencing (where data connection drops randomly, apparently coinciding with a lot of switching between 3G/H/H+).
Initially, people suggested disabling 'fast dormancy' using *#*#9900#*#*, however, this did not work for many, including myself.
In this post http://forum.xda-developers.com/showpost.php?p=15250511&postcount=6, there appears to be a solution, albeit a workaround.
I have started this thread, as there are so many separate threads about this issue, and only the Telstra Australia thread had this answer (as far as I've read). I have copied the post (a repost from whirlpool) by dusty_nz below. Basically, the problem is serious, the guys from Samsung have insisted this will be fixed in KE9, but there is a workaround in the mean time (disabling H+ and H, or just disabling H+ using *#301279#). This may seem drastic to speed freaks, but 3G connection alone should still give you 1.5 Mb up/down if you can put up with that. This has worked for me, no more data stalling, no more server errors etc. etc. I hope H/H+ will be fixed in future firmware.
Here is the post:

****************** FIXED ******************
After contacting Samsung for an insane period of time (ended up on an international call to England i think... or now that i think about it could have just been some English guy in Aus lol) I have got an official explanation and confirmation that this issue is being looked into for KE8 (but it appears that KE8 has been launched in India already so it might be KE9).
*disclaimer*
I am no expert on mobile technology this in-depth however the (probably very) dumbed down version the Samsung guy told me was this;
*end disclaimer*
The problem stems from the fact that this phone has 3 forms of data connection, 3G, HSDPA, and HSPA+.
3G is what we have all had since 3/Telstra launch 10 years ago.
HSDPA is the 7.2mbps connections that we got after that.
HSPA+ is the full fledged 42mbps Next G stuff that only Telstra has.
The problem is, when you are just using the phone as "a phone" it idles on a 3G connection to save battery and when you initiate a data connection it flicks on to the higher connection protocols for better speed.
What is supposed to happen when you initiate the data connection is the phone checks for H+ connection, then for H and then finally 3G. For some reason if you arent with Telstra or are in an area without HSPA+ the phone gets hung up for too long attempting to initiate the H+ connection and refuses to drop back to H!
Also, even if it does give up on H+ it then has an issue with falling back to 3G. Resulting in the problem that if it cant get H+ or the tower is too flooded for a H connection you get absolutely nothing until you restart the data mode within the phone, renegotiates with the tower and BAM, you are back in business.
So... there are 5 fixes;
1. Wait for KE9 (or what ever firmware fixes the modem timings etc)
2. Get a Telstra sim and never leave an area that has H+
3. Turn off/on data mode whenever it happens
to which i told him they were stupid answers and completely unacceptable, but then he came out with this complete gem!
4. using service code *#301279# you can turn off HSPA+ completely forcing it to start the data connections on HSDPA
5. using *#301279# again you can just turn off HSPA+ and HSDPA meaning it instantly starts downloading the data on 3G without delay
Now yes, i thought... great... ive bought this $779 phone that has all the latest and greatest technology and I cant even use it! But, I did some testing!
First of all my normal sim is Vodafone so turning off HSPA+ is an obvious one for me, im never going to get it so why bother. So now that the phone only attempts to get a connection with HSDPA the need to turn off and on data connection was getting more and more rare but still having the problem (i have a feeling that is due to congestion?). So i bumped it down to 3G only and it works perfectly 100% of the time!
The point of these faster connection protocols is speed so i did testing.
Vodafone sim, 4 bars of signal in the middle of a shopping centre.
HPSA+ turned on = 4mbps down, 1mbps up
HSDPA turned on = 4mbps down, 1mbps up
3G only = 3.5mbps down, 1mbps up
did this over and over and over again and to be perfectly honest, im willing to lose 500kbps to make sure that data always works and if you are just doing general web browsing the time it takes to initiate the HSDPA connection wastes more time than the slightly slower speeds with 3G does.
Now obviously this only works fine in my situation, if you are with Telstra and going from HSPA+ down to 3G means going from 20mbps to 3... i would be pissed. But for the rest of the country you are talking about a loss of less than 1mbps so in real world situations with just small amounts of burst data its fine
TLDR; Try and go online and the 3G up arrow lights up but never actually downloads anything
Dial: *#301279# – Change HSPA revision – Release 5 HSPDA only
test, if still a problem
Dial: *#301279# – Change HSPA revision – Release R99 HSPA off
Your welcome, Peace out!

this works! thanks!

Just tried this and I got 1800kbps on 3g!!

Hmm, i played around with those codes. If i choose to drop H+ and H, stays on 3G, but speed is crappy for me. So i want to drop only H+, but when i do that phone stays only on 3G too, not attempting to connect to H. Am i doing something wrong ?

*#301279#
Option [1] Release R99(HSPA OFF) - This should turn H+ and H off
Option [2] Release 5(HSDPA ONLY) - This should turn just H+ off (what you want)
Option [3] Release 6(HSDPA/HSUPA) - This should turn H+ and H on
To test this, you might want to make sure you are in an area that can pick up 3G, H and H+.
One week on since I selected Option [1] and I have not had any data stalling issues, before I was having data dropping every few minutes whilst browsing.
I tried Option [2] and still had the stalling issue.
Good luck.

I hardly ever get H+, which is why i want to turn it off, thing is if i choose option 2, i only get 3G, while with option 3 i get 3G and H (probably H+ too if i were in the right place). Option 1 works fine, doesn't seem to stall, but 3G speed is crap in my network, that's why i wanted option 2.

Tried all three settings and I am getting about the same speeds with all three settings, 3600-4200 down and 1550-1620 up. So will try setting 1 to see if my connection carries on dropping out.
Thanks

Wat is the code for miui
Sent from my GT-I9100 using XDA Premium App

I actually tried this before on a few different radios and it didn't really work. The real problem I have is when I get in an elevator for a minute and get out shortly. It's not long enough in the elevator for the phone to say "No Signal" but it's still long enough for the data connection to hang and never bother hooking back up when I get off the elevator.
I'll try again though... will report back.

same here .... i tried the three options but problem persist

I have tried the codes above, including disabling dormancy but my internet still will not connect to the internet. Please help.

I'm with Optus (TPG) and I never really see H. It's either 3G, or H+.
I tried disabling H+ (option 2), and like the other guy now I only see 3G.
My Speedtest with only 3G was:
Down - 228.2kB/s
With H+ enabled (option 3), my Speedtest was:
Down - 482kB/s (but it's been as high as 1103.9kB/s in previous tests.
For now I'll just keep it as it is and put up with the occasional freezes. Hopefully it's fixed soon in a firmware release.

i cant seem to get the codes working.. after i dial *#301279# nothing happens, no menu nothing. tried on my wife's galaxy s 2 same thing.. is there an app to disable HSDPA?

\\Issue solved

Is this issue mainly due to the carrier?
I did not have this problem b4. Now I found that my phone might suffer from this.
Tried to disable the H+ or H & H+ at the same time, it seems the issue is still there.
I am on Vodafone Australia network. And I just raised this similar topic on Whirlpool, if you guys would like to discuss this network problem on an OZ forum, plz refer to the below

For me it's still the same, coming from KF2 to KG2. Will try KG3.

Any one with new modem firmware that 100% fixed the 3G drop/stuck connection(only see upload sign lit) bug? I am running KG1 modem(stock rom no root) and still experiencing this issue on ATT in Bloomington, Indiana USA.
I also realized S2 uses Infineon modem chip which is the same supplier for the iPhone3G that had the 3G slow down, drop call issue..
Could this issue be the chip at the end?? Why would Samsung taking forever to fix this critical flaw on I9100??

I'm on 3 UK. Had the cutout on KG1 and KG2. But it's definitely gone away in KG3.

I'm on Airtel India on KG3 and I still have the data stalling issue.
Seems to me like this issue surfaces more when I'm at home on wifi and then step out to data.
Trying out these service codes now to see if it helps to turn off high speed data.
It would make sense for Samsung to include these settings in the rom itself even for those without issues but want to save battery.

[Q] Dropping data connection

anyone experiencing data drops particularly when the phone is in weak 4G coverage? It acts like it cant switch between 4G and 3G. sometimes it might take 5 min or more before it will reconnect to data. the phone works fine when it is in a strong signal area. So far I have just experienced this behavior in low signal coverage.

Yesss! Experienced that yesterday. But came back on in 5 min. Usually fixed when u go to settings and switch from the lte to GSM and back to lte but haven't had trouble with it today

Yours is the first case I've seen where data drops altogether, most have just been going back to 3G too often.

I am having the no data issue as well! I leave my house (on wifi and supposedly 3G or 4G) and I want to start listening to music immediately in my car but I have no data connection once wifi is off. It can take over a minute or more to get a data connection! I was wondering if this had to do with LTE protocol negotiation, as this is my first 4G phone. However it seems way too slow and its very aggravating. When it does get data back, it is usually 4G not 3G. Toggling data mode on and off doesn't fix it. I have not yet tried toggling between CDMA and GSM.

does it only happen when you're leaving wifi and going to cell data?

My experience with data connection was spotty for the first couple days. Going from WiFi into 4G then 3G on the way to work required a reboot to pick up the 3G after I arrived.
I think I may have found my issue.
Settings -> More... -> Mobile Networks -> Network Mode
Was originally set to "Global". I've found that "LTE/CDMA" works better for me.
hope this helps some.

3G Data Not Working

Problem has been resolved. See my final post in this thread.
Long time lurker. First time poster.
I am having problems getting 3G data on my new phone.
Last week I activated a new Moto X Pure Edition on the Sprint network via MVNO Ting. The phone appeared to activate just fine. Voice, text, LTE, Wi-Fi, and 1x data are all working without any obvious issues. Phone is pure stock.
3G data is not working. If I set Preferred Network Type to "LTE (recommended)", mobile data works on LTE but if I travel to an area that has not yet been upgraded to LTE, it will not drop back to 3G. Further, if I choose 3G as the Preferred Network Type regardless of whether the phone is connected to an LTE tower or a non-LTE tower, I get no data connection. Same for Global - no 3G connection.
If I choose "1x" as the Preferred Network Type (whether in an LTE area or not) then the phone will establish a data connection. The phone reports this connection as 3G in the status bar but the speed is so unusable that I doubt it can be a 3G connection.
I've done a carrier wipe, updated the device config (profile) and updated the PRL, all several times. Nothing changed. I've also done a factory reset which also did not help. I did not have any issues with my Nexus 5 which the MXPE replaced. I have since reactivated the Nexus 5 with a new number while troubleshooting this problem and it reactivated just fine. No issues at all.
Questions:
1) SignalCheck Pro reports that mobile data is "unregistered" when trying to get 3G data. Is registration of 3G data tied to the SIM card or to the MEID of the phone? Trying to determine if the registration problem lies with the SIM, the phone, or the network.
2) Why would I be able to get a 1x data connection but not 3G?
3) Ting is suggesting network problems may be playing a part but I'm not sure as the problem has persisted through several cities around west Texas and eastern New Mexico and throughout Lubbock TX which has many cell towers. Is there any way this could be a network issue?
4) Is the SIM for the MXPE compatible with my old Nexus 5? I'm wondering if swapping the SIM into my N5 will help to diagnose the problem.
5) Is anyone else with a MXPE having issues with 3G data?
This one is puzzling and I need some help from the gurus. Thanks much.

Bump.

Swapped SIMS with one sent by Ting to verify the problem wasn't with the SIM. Still no 3G.

Yes..i am having the same issue..with vodafone in india

Update. After two Moto X PE phones, numerous factory resets, much research and testing, there is now a work around to this problem. The problem does not appear to impact any phones on the big 4 networks. It only impacts phones on a Sprint MVNO.
There are now known eHRPD issues with Sprint and their MVNOs. The work around solution is to disable eHRPD. Sprint is working on changes to eHRPD that may resolve the issue permanently. Thanks to Ting for their persistence in helping get to the bottom of this problem.
DC

Final update. Earlier this month Sprint released some changes to the way eHRPD handoffs are handled and that resolved my issue. My Moto X PE now works as it should with no workarounds necessary to get 3G data.

So why not work 3g? Is the problem in cell operator?

^^Sprint had some issues with 3g (ehrpd) on mvno's. It would work if forced to evdo, but not ehrpd. Sprint made some changes to their network so this now works correctly. It was a network side issue.

928i 4G not working, 3G intermittent and dropping calls - recently started occuring

this phone has started playing up, 4G wont connect at all and 3G is constantly changing between H and H+. Phone calls dropping and battery draining fast.
Have tried factory reset
flashing older Samsung firmware
Nothing is making a difference. Tried my SIM in another phone and it instantly connects to 4g.
This only started about two weeks ago.
Any one else have this issue? i'm in the uk on the 3 network.
UPDATE: it appears the 4G radio is faulty - setting it to 3g only solves the issues.
UPDATE : I'm so gutted that this phone 4g/3G is ****. Love the phone but loads of people and reviews suggesting 4g/3G issues with this phone and high number of call drops. I did a test today, I put my sim in an iPhone 6 and instantly connected to 4g and speed test was through the roof peaking at 38mb. Put the sim back into the s6 edge plus and only connects to 3G. But unable to browse the Internet. This confirms my fears that the 4g chipset/antenna are ****. In this phone. Which is a real shame as the phone is my favorite ever. Going to get an iPhone now. Connectivity is the most important thing and I can't be dealing with this crap from such an expensive phone. Shame on you Samsung.

I have the exact trouble as yours whichs about constantly changing between the H and H+. (4G is not matter, its new around here). When it turns on H, doesnt connect any site and application which need data connection. But H+ is doing normal. I bought an unlimited data package is provided for up limit 7.2Mbps. Dug something and saw that HSDPA(H) technology's up limit is 7.2 for our carrier. Then bought limited turbo data package(shows as up limit 43Mbps) but still changing H and H+ Thats not such for current device. It was in such an annoying situation since H+ available to connect. Tried to force use H+ but no luck. Sorry for long article and bad grammar. Just saying. Thanks.

Been doing a lot of research and it appears to me that this phone is crap at holding 4g/3G signals. I think this is a hardware/design fault. Most people won't release this until they test this on an iPhone in the same location and see the huge difference. Can't believe Samsung would release a huge pile of crap.
