Going to be in the Philippines next week and I've pre-ordered a local SIM. I have an unlock code from ATT as well as have International Roaming enabled on my current account.
ATT said all I have to do is enter the code when I turn on my phone with the new SIM installed. Now ... the code, was that tied to the original ATT ROM? Because if it is, I can't see how the phone will accept a code that was wiped out with a flash?

Unless you ran a sim unlocker, the code is good no matter what rom you are using.
And unless you are planning on using att in the Philippines, get rid of that international roaming feature, you are just wasting money.
here's how it works: when you put in a sim card other than AT&T, the phone will ask for the network unlocking code regardless of the ROM...so if you have the code got from AT&T you're sorted.
as for the int'l roaming on your acc, not needed as the previous fella said.
hope that sorts you out
Thanks guys, sounds good! Apparently int'l roaming isn't something that they charge for according to the att rep I just spoke with.
No... but if you land in the Phillipines with that ATT SIM in the phone and you start roaming, even a incoming call that you DONT answer or a voicemail notification gets billed!! I know TMobile does ! Dont ask me how
I have been digging through the threads and it gets confusing with different people referring to unlocked tablets that are overseas etc.
I have a tmobile US springboard that is running the most recent rooted mediapad rom from this board (it runs great btw).
I was hoping I could use this device as my phone. I rarely take voice calls on the phone. I have Bluetooth in my car which is really the only place I talk to anyone and I have a Bluetooth headset if I need it. Most of the time I send texts and use data.
The problem is that when I put my phone sim card in the tablet, phone and sms work fine but data stops working (more specifically, it redirects to my.tmobile.com). From what I have read, I think we are just going to have to deal with it for now but I wanted to see if there are any options because some people thought that removing the imei file would help. There is also some stuff about data in the build.prop for the device.
How about getting a device subsidy unlock code from t-mobile? I should be eligible.
IMEI unlock
I copy and paste tmobile policy as blow:
support.t-mobile.com/docs/DOC-1588
" For information on the SIM Unlock Code, refer to the following:
If you purchased a device from T-Mobile, it has been programmed with a SIM lock which will prevent the phone from operating with other compatible wireless telephone carrier’s services. If you wish to use the phone with the service of another wireless telephone carrier, you must enter a numeric SIM Unlock Code to unlock the phone.
If you have a Postpaid Plan, T-Mobile will provide the SIM Unlock Code upon request to eligible customers, provided the requesting customer has a minimum of 40 days of active service with T-Mobile and did not request a Subsidy unlock code in the last 90 days.
For customers with a Prepaid Plan, T-Mobile will provide the SIM Unlock Code upon request to eligible customers, provided the requesting customer has a minimum of 60 days of active service with T-Mobile and either a Prepaid Plan account balance of at least $10.00 or a prior refill within the last 30 days.
T-Mobile will provide the SIM Unlock Code upon request to eligible former customers, provided that T-Mobile has such code or can obtain it from the manufacturer.
If you paid full retail price for a device, you qualify to have the SIM subsidy unlock code providedif you meet the following requirements:
The device must have been purchased at a T-Mobile retail store or authorized T-Mobile retailer.
The device must be paid for completely. You must be able to fax the proof of purchase to T-Mobile."
As indicated if the device is paid for completely, we qualify to have the unlock code. Have you or anyone tried to get an unlock code and tested?
I bought a Springboard on ebay and signed up for prepaid data for 60 days with tmobile after which time I requested a SIM unlock. I received the unlock code and after inserting my AT&T sim I'm able to make calls , get data, and text.
I can't specifically verify which bands on ATT nor whether I am getting real 3G data. I can verify that I am able to talk, text, get data.

If you're able to get more than 384kbps then you've got HSDPA/HSUPA/HSPA or whatever (real 3G is 384kbps). On most country, the signal label would change to H, on T-Mobile it would probably change to 4G. I can't exactly verify the label change though, since I'm on a data plan with 3G only speed (so my top speed is 384kbps).
If you can't trust the label then use those speed test app and verify it yourself.

I have a question: Since your device has updated firmware (mine is running ICS), does it mean it has been unlocked already? Have you tried a SIM from another carrier? In another word, will updating to a generic firmware unlock tablet automatically? My reasoning is that all the coding/decoding is through software and an updated generic firmware removes all the T-mobile stuff as far as I can tell. The software that is in charge of sim lock is very likely been replaced as well. My doubt is that people can then buy a Springboard with data contract at a much lower price and update the firmware to remove the lock. I bet T-mobile is smart enough not to let that happen.
I finally got the unlock code from T-mobile and bought an ATT sim card. Unlock is not that as simple as I thought to be. Strangely, my ICS does not pop up the unlock code entering interface. I cannot remember from which post I downloaded the ICS. It is within "the" giant thread. By using the famous ()()2846579()()=, it showed nothing after "SIM card lock state". So I flash back to HC3.2 and unlock the device in the pop up interface. After flashing again to the most recent general firmware from huaweidevice.com, it shows "SIMLOCK_DEACTIVE" after "SIM card lock state". Recalling the sim card lock status is one of the features installed after a second boot during the installation and I did not recall my first ICS did that, I am wondering if the first ICS does not install the component related to sim card lock status. Probably my springboard under first ICS is unlocked by software.
Anyway, I am pretty happy with the latest version and have an officially unlocked springboard. From this experience I learned that SIM card lock status in general does not change after update the firmware (at least the official one). And probably someone can do it by modifying the firmware by his/her own.
By the way the ICS I first had has no fastboot option.

I am thinking of unlocking too and I am wondering where you found the HC3.2 to flash? I searched the forum and the only one I found appeared to be made up of many smaller files. There appeared to be multiple versions of files and I was not sure which ones I needed and how to flash them.
If you only want to unlock, flash the latest ics for general purpose from Huawei. The unlock interface appears after you insert a sim card other than tmobile.
Sent from my HUAWEI MediaPad using XDA
I just flew in to Spain for study abroad here for the next 4 months and wanted to take my ATT Atrix along for the ride. So I called ATT, got the unlock code from them, and after much difficulty and having to flash a Brazil Radio to negate the maximum number of tries limit, I got it carrier unlocked. The SIM I am using now is a prepaid Yoigo card (funny name, i know). I also reflashed the .36P radio.
The weird thing is that Onavo Count still says I am roaming, even though I have a local SIM in Barcelona. Is this an issue with Onavo Count? Or is the phone really still thinking it's roaming? Is it the radio? After every reboot, the phone makes me enter the SIM Pin. Is that an issue with the sim card and the phone getting along, or just the standard SIM security feature doing it's job.
Im running cm7 rc1 with the .36P radio.
Thanks in advance.
No service / emergency calls only on AT&T.
Help please - on "new" unlocked GT-I9100, running SlimBean 4.2.2.build.7-OFFICIAL. This phone is for international use, but my sister-in-law is trying to use it in the states on AT&T prepaid. The phone gives all indication that it's unlocked successfully. Note that the same issue happened on 2.3.5 stock, so it's definitely not the ROM.
No signal or service on a new AT&T sim card (prepaid). Brought the card to the store, tried a different one, same issue.
Available networks: "AT&T" & "US". Clicking on either gives "Can't register on this network right now."
Tried a friend's T-Mobile SIM card, got weak service but was able to make a call successfully.
Running basebank I9100XXKI4. Had KI3 originally, same result.
ESN is clean and unmodified. Passed online ESN verification sites.
Any and all advice is appreciated!
What's the status on this??? I bought an s2 gt-i9100 of ebay. The phone works just fine with tmobile but stays on emergency mode with full bars on at&t. It's really weird since my tmobile sim is 7 years old and the at&t is only 2. Any help on this is appreciated.
Hi,
I'm in South Africa and I bought a SM-G991U1 (US unlocked version) on Amazon Renewed and everything works fine except for mobile connectivity.
I get the "Your phone's not registered on a network" message if I try to make a call and mobile data does not work.
I've tried:
- Resetting network settings
- Manually setting APN details
- Tried a few other SIMs from different carriers as well that work in other phones
- Checked IMEI info, doesn't seem corrupted or 'null'
I suspect that the modem firmware or something else is region specific to the US on this model and not working on South African networks as the phone does support our network bands according to GSMarena.
Would it be possible to re-flash the modem firmware or fix the issue some other way?
Hello I'm having the same problem, have you find any info about it?
Not much, I went to a carrier store and the phone seemed to work alright there after rebooting the phone with the sim card installed. I am starting to suspect that the phone doesn't like my closest cell tower maybe? Or possibly doesn't like using another carrier's mobile tower?
No idea.
I've since bought an identical but South African version of the same S21 which works flawlessly.
As a quick rant for anyone considering buying from Amazon: I tried to return the phone, shipping it back to the US and everything, only for Amazon to refuse to pay the import duties on it once it arrived, forcing DHL send it right back and charging me for it again
