2g - ok, 3g - does not work - Networking

Hello, my mobile phone does not want to find 3g/WCDMA network. With 2g conections everthing is ok, but when I choose "only WCDMA mode" It can not find network (on both sim cards). I am sure I am in area with strong 3g signal
I want to know it is software or hardware problem? Does mobile phone has diferent modems for 2g and 3g connections with different antennas and different modems firmware. Or maybe it is one module?
Note 3 neo 7502 dual sim
Thanks very much!

It depends on where you live in the world and if your phone has the right bands for 3g. It may be designed for UK and you try to use in US and if the bands do not match for your provider(s) it will not work.

This phone is designed for Ukraine (UCRF). And I am using it here, It have label in Ukrainian language on the body and also on the box.
I am sure it sertificated for Ukraine, and band are right, (HSPA+ (850/900/1900/2100MHz - it is information from box)
But something is broken. I want to know it is software of hardware problem.

Are your providers doing 3g. Contact them and make sure. They may have to issue you replacement SIM Cards. Make sure they have that active on your plans.

3g problems

Hi. Newbie in this forum. Bought an htc tytn from u.s. but am from Phil using smart carrier with gsm band at 1800. after going thru sev topics, properly identified device as Herm200 rom:1.18.255.3 07/22/06 extrom:1.18.255.106 radio1.03.03.10 protocol32.34.7010.01H.
All phone features working perfectly except for 3G. Smart carrier people cannot help. What could be wrong. Vendor says 3g works on 2100 band. Confusing statement. What can be done? Connects to umts but when video call is pressed will not connect.
Which carrier are you on again? Smart Carrier? .. From what I know no carriers in the US support video calling .. Also, Cingular is the only GSM carrier in the US with 3G which runs on the 1900Mhz band ..
also .. what does your phone display while connected "G" or "U" ... what are your phone band settings .. can you also goto dslreports.com/mspeed and see what speeds are you getting ..
According to GSM world SMART (a Philippine operator) uses UMTS 2100, which your TyTN does definitely support.
Have you checked if your SIM card is 3G-enabled? Most 3G networks require special USIMs for 3G usage.
I just learned, that Cingular uses UMTS 850 and 1900 to be exact. According to the American HTC website the Cingular 8525 supports "Tri-band UMTS/HSDPA high speed wireless data network support (2100MHz and 850/1900 MHz), Quad-band GSMĀ®/GPRS/EDGE worldphone".
Does anyone know if there is a special hardware version, that supports UMTS850 & 1900 or will my European TyTN work on those networks, too?
TyTN is tri-band UMTS .. 850/1900/2100 .. so it should work on these networks without any issues ...
And my bad .. didnt realize that you are trying to use the TyTN in Phillipines ..
You should also check, if the called party has a 3G signal, while you call him. Further make sure video calls are activated by your network operator.
3g problems in the philippines
Everything you guys mentioned in order(am in a 3g area calling a 3g enabled party with a 3g sim card). Even the tech staff behind Smart Communications cannot make it work. Displays U and u. But video call cannot push thru even if pic on front camera shows. There is 1 thin line( or command?) stopping it from connecting. My last option is to borrow my friend's unit and see if her unit's 3g works here then it's my device that's a problem. Thnks for the input. Keep it coming.

Hi. I don't know how they did it but Smart Communications did it! Apparently and ironically their 3g sim card is not compatible with the htc tytn but their regular sim is. Thanks all.
are u using 3G now in Phil ?
Is there a Globe perpaid 3G simcard ?
3g problems no more
Hi everyone. After my first thread i have finally got everything on my tytn working: 3g, mms, internet, phone. The problem was on the settings. Smart and Globe, the primary carriers in the Philippines can both work on the phone if the settings are right.
sectorlord,
yes there is 3g and hsdpa along with gsm and gprs and wap in the philippines. and yes you can buy globe prepaid 3g sim card.
glad to hear you've got your problems solved jjc!

Network problem with Blackstone

Hi I would like you to help me with my network settings.
I'm from Mexico city and I bought a HTC Blackstone few days ago. First of all let me tell you that in my country we don't have a provider for HTC phones, we just have some of them but the old ones. So I bough my Blackstone from a US online-store.
I did Hard SPL on my phone and installed Laurentius26 "L26_THDV5" ROM. After that I took some time to configure the network settings from my country and everything was ok. But my problem is that my Blackstone is not working on 3G mode, it's using EDGE. Actually I don't know how far the differences are, but I can feel that it's slower with Youtube or Internet than my previous phone (a Nokia N75). I don't know if I changed something with the new ROM or if there is some way to fix it and work on 3G mode because actually I'm paying that service with my provider (Telcel).
Please, could someone help me with it?
The Nokia N75 supports the 850MHz / 1900MHz 3G bands.
The HTC Touch HD supports the 900MHz / 2100MHz 3G bands.
Depending on your provider you will not have 3G at all.
are you sure ?
I've started a thread about this:
http://forum.xda-developers.com/showthread.php?t=477426
in the menu: phone - options - BAND
which options are present?

[Q] Please help.

Hi guys.
I got a highly noobish and probably stupid question about my Nexus One.
Using the *#*#4636#*#* / phone information / network type: EDGE.
My wife's wildfire shows HSDPA and we ure under the same operator.
So, its a phone problem? It doesnt support HSDPA? If so, how to change that?
I understand there are 2 versions of Nexus One, how to figure out which one I have?
Thanks in advance!
There are 2 versions of the Nexus 1 that are out. One that works with tmobile 3g and one that works with at&t 3g. If you use the tmobile version with at&t you will only be able to get EDGE.
How long have you had your N1? Did you buy it new or used? Who is your provider?

Thank you for your answer. Really fast.
I live in Colombia, South America. My provider is movistar.
I have the nexus about 6 months ago. Rooted. Running CM nightlies.
What do you say about the result on *#*#4636#*#*??
Thanks again.
movistar uses 2100mhz for hsdpa in colombia correct? Both the wildfire and nexus one should support 2100mhz no matter what version you have, so you should be able to get it on both phones if it's available. The only reason maybe you wouldn't is that you have the "Use only 2G networks" option enabled?
Something else, in the data icon of the notification bar does it say the same thing as it does on the phone information screen, or do they both indicate edge?

2G Networks only unchecked.
Indicate Edge in notification bar and in phone information (4636).
Is there a way to change or fix this thing out?
Thank you.

This is true on both phones? But it is only the wildfire that says hsdpa in phone information?
In phone information, scroll down a bit to the drop down box of network types above "Turn off radio". What is this setting?

Wildfire: WCDMA preferred.
Nexus: WCDMA preferred.
Set both to GSM only. After a minute, if the wildfire still says hsdpa then it is likely a firmware issue where the connection information is permanately set to "hsdpa" or it doesn't update as it should. Have you traveled into an hsdpa service area recently?
Do you think changing the radio band may work? I didnt see any checked right now... in any of the phones...

After a while the wildfire was unable to coneect via data connection when I put GSM only.
When changing to GSM only, the nexus keeps showing E.
The radio band should auto-adjust based on what is available. I don't know that you can specify a certain radio band in android.
The wildfire has "E" in the notification bar at all times, correct?

No, the wildfire has H, the Nexus E.
movistar does not use the same bands for gsm and hsdpa anyway, this is a strange issue but I suspect it is simply a firmware issue
Edit: Maybe what I read was wrong. Do you know for sure what your provider uses for hsdpa in your area?
One version of the nexus one uses 850/1900/2100 and the other uses 900/1700/2100 for hsdpa, while the wildfire uses 900/2100. But they both have 850/900/1800/1900 for gsm. I didn't think 900mhz was used in South America?

Let me ask first. If the phone shows H not necessarily theres HDSPA? Is what you mean?
They claim to offer 3.5g. Edge is 3g? Hsdpa is 3.5g?
The only thing I can think of is that your provider is using 900mhz for hsdpa and you have the wrong version of the nexus so you will not be able to use that band. Or, you have gsm 900 available and not hsdpa at all and the wildfire is interpreting gsm as hsdpa. Download a speedtest app and see if the connection speed on the two phones is actually any different.

How can I know?
I know, the other carrier claims hsdpa, COMCEL is the name of the operator.
But if my phone is configured to EDGE, what can I do then?
I'm sorry this issue is so confusing. I read conflicting information about what bands Movistar is using for gsm and hsdpa in your country. The operator name in the notification bar is Movistar, correct? If it is, the wildfire can not be using COMCEL.

S5360L band changing ?

hi
i have here few PCS of S5630L
its same phone but bands are not the same.
HSDPA 7.2 850/1900MHz
anyone think it can be changed via software ? or its a hardware issue ?
if so can i change bands filters ?
thx
anything ? anyone ?
it can never be done,
it is the internal radio which transmits and receives frequencies,
which is a hardware thing,
if i got you correctly S530L is CDMA and you want a GSM band

This model is not cdma, irs gsm model fits to some countries like brazil and argentina.
so this phone works only on quad gsm 2g network with no, but on 3g networks it works only on 850/1900 and i need 2100
On older nokia phones we changed anttena duplexer and bands filters and it did the job.
On newer phone like i9000 we can change bands via programing menu.
I just wonder if it can be done even with hardware changes.
Thanks
Anyone ??
I tried *#*#197328640#*#* but not working

No 4G/LTE with SM-G935FD

I have a new SM-G935FD purchased in the UAE. The software version is MMB29K.G935FXXU1APD1. The phone has a "United Arab Emirates" section in the About page.
I travel a lot. I generally use a local SIM when I am in a country for some time. Right now I am in France. I am using a SIM from Bouygues Telecom but I have no 4G/LTE service at all. The phone is connecting at H+ and also at 3G, but it is not showing 4G/LTE at all.
I will be in several other European countries as well as the US soon. I specifically purchased this phone because it has all the LTE bands for the countries I spend time in. This same SIM does give me LTE connections on Bouygues when I use it in my old phone (a Motorola X 2nd Gen). I had expected this phone to just work on LTE everywhere that I typically go.
I have looked through these forums and see a thread or two about others with LTE problems. But no clear solutions.
I have tried various apps such as LTE Discovery (no luck) as well as 4G LTE Switcher - using that if I set "LTE only", I get no service at all, and then have to reboot the phone before I get service back.
Is there something I need to do to get LTE?
Thanks.
Have you put the SIM in the correct slot?

Yes, the bottom slot. The SDcard is in the top slot. The SIM is showing in the phone as "SIM1".
Strange. I have a G935FD and it works with LTE no problems. I've used it in Singapore and Indonesia, with different SIMs and all work.
In Settings - Mobile Networks - Network Mode, it's set to LTE/3G/2G?

Yes it is. I've tried changing to one of the non-LTE modes and back, but no change.
In the About device / Status / SIM Card status page, I see Mobile network type as UTMS. Shouldn't that have LTE and, if so, how do I change it?
Mine says the same, but I'm only connected to 3G at the moment, so I don't know if it's normal it not. I have a 4G card in, but I'm out of my area's 4G network range.
Edit: Actually I was connected to my wifi. Now I'm connected to my 3G and it says HSPA+ now
Edit again: Ok, so my phone is jumping between 3G and H+, which is what's changing.

Ah, mine is doing the same. I see Mobile network type jumping between UMTS and HSPA+ if I watch for a while. Obviously that field is a status field, not a setting field.
Thing is, I am in an area with full LTE coverage.
At least you seem to be confirming that this should work. Still need to figure out what the problem is.
I have the same Problem in Spain. With a Vodafone Card I dont have 4G Connection (The same card in a the Galaxy S5 of my wife works with 4G). But with a Yoigo Card I have 4G Connection. The software version is MMB29K.G935FXXU1BPH6. The phone has a "United Arab Emirates" section in the About page too. Any Idea?
Thanks
