Your ability to get 3g will depend on if the phone supports the frequency american 3g is on. A lot of foreign phones don't
I had a hard time getting to cell me a data package too for my phone since I bought it unlocked. The a holes act like "if its not ours we cant guarantee it will work!" then they wouldn't cell me a data package except the crappy medianet one (I should have been dishonest and taken it, would saved $15 a month for the same service). Called back, got a different rep, gave him the IMEI number, told him it was a PDA, went smoothly.

how to: debrand and unlock desire S

I have a desire s on Tmobile and want to debrand it to see if this solves my problems in failing to receive texts and phone calls.
Can anyone tell me the easiest way to do this, and can i rebrand the phone if I need to send it back?
Links or a how to guides would be great thanks!

De-branding alone won't resolve errors on your phone, but will void your warranty.
If your problems are reproductive and not just intermittent then I'd suggest that you return your device under warranty and seek a replacement.

Iv had 2 desire s from tmobile now both have done the same thing, I am sure its not a hardware issue I think its a problem with the tmobile software, or whatever enables it to use orange signal aswell

Hmmm....?
I can only take you at your word....but, my wife has a branded T-mobile desire s which functions fine and has done for over a month now.
Where as I have a non-branded desire s which also runs on T-mobile but is unlocked and runs customs ROM which also runs fine.
Failing to receive texts does sound like a network issue not a device problem?

I also have a t-mobile desire s and all works fine, am on custom rom at the moment and have tried most of them and not had a problem with any off them. Also all worked well when it was stock rom.
Are you sure all your apn settings are correct.

Google APN settings, they're easily found.
But I don't think these settings affect the way you receive texts or make calls, they're just for data, no?

Getting Cell Service with NO SIM! And some other guys number ! Help

I just bought a phone the guy who made no mention of the fact that it was rooted when I bought it. What is worse is he mentioned that his GF worked for Verizon, which did not seem to mean much at the time. Knowing that here is what i'm dealing with.
I was in a rush when I checked out the phone as I had to meet another person to pick one up for my wife as well. It's the sch-i575 in white 16gb. After having a minute to look at the phone it turns out he had Paranoid Android flashed and the phone was rooted. CRAP! Not what I was looking for and he was not upfront about it. The incredibly strange thing was that with NO SIMCARD the phone was getting 3g signal! I spent all night trying to unroot \ undo what he did. I managed to use ODIN to get back to the stock rom although I think it's still a rooted one since I still have the super user app. I got a sim card from verizon but since it was rooted I did not bring the phone in and when I tried to activate later it would not activate. My wife's by the way is working flawless and when I put my sim in her phone it works fine as well. I had to put the sim in my wife's phone and it activated there. Here is the crazy thing, with or with out a simcard the phone makes calls and has 3g internet only but when I make a call it uses HIS NUMBER!! I'm not sure what the hell to do, what could have he done? Any ideas? Please all help is appreciated! I did not think this was even possible for the phone to function w/o a sim. I'm worried about taking it in to Verizon because of the funkiness. Ty again for any insight...

I thought the I575 was an old slide phone. So A. your in the wrong section of the forum since this is Verizon's S3 or B. you mentioned the wrong device number? I saw phones before working and running on networks without sim-cards but that was years ago. If it is an S3, you sure it's a Verizon device? Also since you see 3g....can you browse around in the browser or make a phone call?

Yes, it's a galaxy s3 16gb in white. It looks like currently I was using the tar66 using ODIN. I'm reverting back to the bone stock one now. As far as the models go isn't the SCH-I575 the Verizon version of the S3?
I'm waiting on the stock unrooted rom to take through ODIN and will report back. Thank you for taking the time to try and help.
Ohh, yes the internet works and when I make phone calls with or with out my sim in it makes calls successfully but the other guys number shows up. What the heck did this guy do to the phone!

Our model is the SCH-i535

You are obviously absolutley correct. I'm frantically trying to figure this out. I have flashed the stock rom and don't have super user anymore. The problem persists with the guys number.
Could he have flashed a custom kernel and modem or does reverting back using the stock rom cover all that ?

The one i linked covers all that and completely erases all data on the phone. Did you insert your sim after the stock flash?

I just double checked and I had the I535VRLAG1 version, yours is the I535VRALF2 in the link you posted trying this now. The crazy thing is that it even says that the sim is activated with MY number! but the calls are still comming from him. I even tried wiping the device and clearing the cache. I also tried to JUST flash the modem with VRLG1.modem.tar.md5 and nothing :\. Waiting on the file from your link to download and will try that.
Is it possible that this is being caused by something on Verizon's end? The phone ( with out the SIM ) is registered to him somehow? I know this is not normal but because his GF worked for Verizon could they have done something funky?

Yeah its definitely possible its from something she did to the phone but most likely nothing from Verizon's end. Does the IMEI number under status match the IMEI number under the battery?

Yes IMEI is the same in the OS as behind the battery.
The curious thing is that on the same screen in the OS where you find the IMEI there is also a field called Network and it says " Unknown"
It also has things like:
Eri v : 5
Mobile network type : EvDo-rev.a:8
The thing I keep coming back to is how is it possible for this phone to make calls\ have data with out a sim?
Starting to really think I got cheated

Cheated? Sounds like you have free Verizon service.
Roll with it. If you really want a bill you can have mine...

Just did and the same thing happened. I went to the Verizon store and the guy there had no idea and got me in touch with tech support from the store. They were dumbfounded and flat out said that what is happening is impossible. "It's impossible to make\receive phone calls with out a sim unless they are emergency" I harped on the fact that I am making phone calls as one of their other customers and that this is a big deal. In the end since I had the insurance and extended warranty they will ship me a new phone.

[Q] abroad - infuse can call only emergency - IMEI ok

I bought an infuse 4G in 2011 in USA then, the same year, I brought it with me in Italy, I unlocked it and it worked since then both in USA and in Europe. I deeply love this phone.
A month ago I accidentally broke some pins of the SIMM socket and then I thought to start using the infuse as a guinea pig to play with android and customized roms.
After many issues and trials and many "return to stock processes", I finally managed to have a working CM9 installed on it. It worked so well that I decided to repair the SIMM socket to use it again. I brought it to the repairing shop and I've got it back a few days ago.
Unfortunately, both with the american and italian SIMM cards I can only call the emergency number (911). Basically it can not register to any network. (btw I'm currently in Italy)
To my understanding if I can call and talk to 911 it should mean that the repairing was good.
I also called my provider to see if my IMEI number is blocked for some reasons but they have confirmed no bad records.
I tried returning to fix things following several guides like:
UCLB3_Unbrick_1.1
Odin_UCKE3_v2
No Voice or Data service after install of CM9 - ##72786#
Recover EFS
but I don't see any way out. The problem is still there and it doesn't change, doesn't matter what I do or what ROM is installed.
Unfortunately, I'm kind of lost here because, apparently, everything works and I don't have any error notification (or simply I don't know where to look at to make some debugging)
Do you have any idea, suggestion?
Thank you!

My only thought would be did they really fix the pins? Seems one of them still isn't making contact. Return it to stock then return it to the shop where you got it fixed and say you are still having problems.

i second this but if the shop that you send it to was in the US then its gonna be a while till you get it back but if they end up not being able too then i would suggest buying a new infuse since its about $80-100 on amazon which you would be able to unlock yourself then start from there but yea go to that shop and if they say its fixed try the sim in front of them to make sure it is fixed because returning to stock fixes most if not all issues

I should add that 911 will work whether a SIM card is in or not, valid or not, working or not. Emergency Call is a safety feature that doesn't discriminate (will connect to any network available). This is why telco's ding you with a 911 fee every month rather than charging you for using it when you really need to.

Thank you all for the suggestions

ha! that I didn't know and it changes EVERYTHING!! I thought that being able to call 911 mean I had no problem with the SIMM socket. After whatever you've told me I do believe that most likely the problem sits in the SIMM socket.
One question though: let's say that it wasn't welded well, is it then possible that I can see the SIMM number in the settings panel but it's still not working?

Forgot about that listing. Think I know why. Just went to that page, and I get an "Unknown" for that value (and my phone portion is working fine).
So that's mixed information, but a pin not making contact still covers that issue. But what it could be is that Access Point Names or Network Operators is out of whack (these things can apparently stay the same between flashes - or at least restored backups - for some reason).
To get to these two options, go to settings, the equivalent of More... under Wireless & Networks (sorry, I'm not on stock at the moment), and select Mobile Networks.

So I just have got back my phone from the repairing shop and ... it works!!
So I confirm that there was an issue in the welding of the SIMM socket. So this means that it's possible to see / access SIMM information if one of the pins is not connected.
Unfortunately the guy wasn't capable to tell me much about what they did exactly (don't ask, too long to explain ) so I don't know exactly what was causing the issue but I'm pretty sure it was one unwelded PIN.
It's also definitely true that you can call 911 even if the SIMM is not working properly or is not well connected to the device.

Question Calls drop after 29m50s

Running xiaomi.eu 13.0.8 stable. All my outgoing calls end at 29m50s.
I have tried calling different numbers so not a problem with the called number. I have put my Vodafone UK SIM in my S22 Ultra and that's fine, but any call I'm on just terminates at 29m50s.
Has anyone else got this problem? Hopefully we'll see an update soon which may fix it.

this could just be your carrier having a call duration restriction, have you tried your sim card in another device to rule out carrier issue?

Yes. It's just the Xiaomi 12S Ultra. With my Vodafone SIM and EE SIM, they both disconnect calls, and in an iPhone, S22, Pixel, etc. they don't

Upgraded to 13.0.9 and still got the issue
Can anyone else try a call and see if they have the same problem?

Has anyone managed to make a call longer than 29m50s?
Just performed a factory reset and same issue.

yea 13.0.10 eu.
no idea. the only thing i noticed is a drop of quality due the spot where i am, constantly changes between 3g, 4g, 5g depending on where i am. but making it 4g only fixes.

So I formatted/wiped and went back to 13.0.8
Managed a 31 minute call
Installed 13.0.10, didn't sign in to anything, update any apps, etc.
Call disconnected at 29m50.
Time to give up with this phone I guess.

Hi,
I'm experiencing the same issue and it's been behaving this way since day 1. I've tried two different SIM cards. I've even gone as far as factory wiping the phone and even disabling VOLTE and using 3G for calls but it hasn't helped. I'm running on the stock CN ROM.
I want to return the phone, but I doubt I'll get it refunded in full since I've been using it for so long and I'm unsure what Giztop would do and how I'd be able to prove to them it's faulty. v13.0.11 was just released recently and it's not helped either.
I've decided I'm going to wait for the Vivo X90 Pro+ or Samsung S23U and be done with this phone since this issue is a dealbreaker as I tend to make a lot of calls since I also use this as both my personal and work phone. I'm kind of disappointed and am going to miss the camera a lot.
