Hello. We are using Motorola Atrix 2 phones for a global public health project and we have run into an issue. We are ordering the phones unlocked from Amazon.com and we are receiving two versions, one that has AT&T printed on it and one that does not. The one that does not works with both a US T-mobile sim and a US AT&T sim so it is truly unlocked. However, in Ethiopia when we insert an Ethiopia telecom sim the About Phone shows Baseband Version -UNKNOWN and if I go into More settings the Mobile Networks is grayed out. If I take the same phone and put in a US T-mobile sim I get the Baseband Version info and the Mobile Networks sees the Ethiopia Telecom network.
I flashed the phone from Android 2.3.6 to 4.0.4.
System version 67.21.125.MB865.ATT.en.US
Model number: MB865
Firmware config version is GAS_NA_EDSNICSATT_P006
Build number is 6.7.2-226-EDICS-10
This is a huge problem for us as we have 24 phones which can't be used for the project. We are trying to find out if this is just an Ethiopia Telecom issue or a worldwide (other than the US apparently) problem.
Please help!!

I just acquired an unlocked AT&T Captivate.
When I put my Bell Canada sim in I can not see/register/connect to the the Bell Network.
If I put my wife's Roger's sim it connects right away and when I enter the Rogers APN info it connects fine to the 3G network.
With the Bell sim in there I cannot even get to the menu for automatically or manually selecting the network as the meni option is grayed out/unselectable.
Any ideas? Are there other Bell Captivate users out there?
edit: with the Rogers sim in there and if I manually search for a network it list Rogers and a 302610 network which suspect is the Bell network as the MCC is 302 and MNC 610 for Bell
maybe video? i wanna see it
is the sim itself ok?
My cap runs fine on bell... I have the network selection part greyed out too but it picks up signal as soon as the sim is in place
Sent from my X10i using XDA App
I am assuming the SIM is fine. It works in an unlocked Telus Hero and an unlocked Rogers Magic. What video would be helpful? Of the settings screen or the no signal icon in my notification bar?
I get no errors or warnings with my Bell sim in there. It just won't find the network.
(and thanks for confirming that there is at least one other cap working on Bell)
My plan is to get Froyo on here anyway. Is changing the ROM or Kernal likely to impact this issue at all?
which band does bell use? which modem you use? (euro or us?)
Bell uses 850 & 1900 - my understanding is that they are same as the Rogers frequencies.
I am assuming I am using a US modem. How do I check the modem? The phone is an AT&T phone that did arrive in my hands rooted and unlocked already so I suppose something else could have been done to it.
more details:
Baseband version: I897UCJH7
Kernel version: 2.6.29 [email protected] #2
build number: ECLAIR.UCJH7
Anyone? I've tried different modems and ROMs including the Bell i9000 modem/rom for the Captivate. Its almost like my sim is bad but I know it works in my htc magic.
well in case some one else has this problem it was the SIM. Apparently there is a problem with a batch of Bell SIMs - they had me swap to a new SIM and I connected immediately.
Woo Hoo!
hey,
i am from India. My friend is going to gift me samsung galaxy s3 (unfortuantely and probably its t-mobile) from United States. i've no idea whether they are CDMA or GSM carrier. if its CDMA so my questions are :
can i get an unlock code which allows me access any gsm networks in India.?
And if it is GSM one, can i access 3g networks in India.?
i have read in a random forum that if its gsm carrier i can only use EDGE service in India.
AND the last one-
should i update official ics stock rom firmware for INDIA OR for The USA?
This is really wierd. Hope someone can help.
I bought an unlocked LG Optimus G E971 phone in Toronto, Canada this May. Inserting a Rogers and Fido SIM card was perfectly fine and working while I was in Toronto Canada. No SIM network unlock PIN required.
In October, I travelled on vacation to Hong Kong with the same phone that I thought was unlocked. As always, I would buy a local SIM for my unlocked phone. To my surprised, it prompted for a SIM network unlock PIN. I went to a total of 3 carriers, including 3 Telecom, China Mobile and one other (cannot remember the name). All asked for a SIM unlock PIN.
Not believing what had happened, I went back to the shop in Toronto, Canada after returning home. Tried inserting Rogers, Fido, Bell and AT & T SIM card, all worked perfectly.
My question is, could this be a region lock? Like the Samsung Galaxy Note 3?
Anyone has similar experience to share?

Probably.
Region locking or maybe that your phone did not have the right baseband? I dont know. My phone had a similar problem, it displayed roaming in the native country I was.
If you find something about it, please do post back, ok. I am very curious to this issue.
You need to unlock the phone from your carrier in order to user unlocked sim on your mobile

I can use both Fido/Rogers and Bell. They are different carriers and Fido and Bell are competitors in Canada. My LG Optimus G E971 is manufacture unlocked meaning its brand new and unlocked when I bought it from the shop. I don't buy locked phones from carriers and I don't need an unlock code. Been buying and using manufacture unlocked GSM phones in the past 10 years, never had an issue. Not a believer of locked phones and it's ripped off plans in North America.

The LG Optimus G E971 is quad band and it has HSDPA 850/1900/2100. I matched this to my Samsung Omnia II (I8000) which has HSDPA 900/1900/2100. My Omnia II is manufacture unlocked and is usable in Hong Kong (Asia) without an issue. Not a phone tech person but I would assume my LG Otpimus G E971 is quad band and is useable in Hong Kong.
I didn't know there was a section for LG Otpimus G, I have also posted my replies here:

Hello,
I have an SIM unlocked but AT&T branded RM-877_nam_att_205 with Lumia Denim Update:
Name: Lumia 1020
Model: NOKIA 909
Carrier: AT&T
OS version: 8.10.14226.359
Firmware revision number: 3051.50009.1451.1001
Hardware revision number: 3.3.0.2
I have a Movistar MX LTE SIM whichs works fine, even tethering works, but even it shows 4G connectivity it does not really connects to LTE, accessing the Field Test ##3282# in the LTE info says:
Sys Mode Invalid
Also in the field test app forcing the phone to connect with 4G only does not work, only with 2G and 3G only modes.
I know there is no way to flash my phone with another ROM other than AT&T one, and I really would not want to change the ROM, but only to get the LTE speed work with my carrier which has already LTE Band 4 enabled in my city.
Is there a way to enable the LTE connectivity without changing the ROM?
Hello,
Im using Moto g4 plus 32gb version in USA which is bought in India few days ago. Also im using Lycamobile carrier here in USA. My problem is im not getting an LTE signal on my device while i changed settings to LTE recommended and others in my area are getting LTE signal for the same carrier. Am i missing something here or is the fault that i brought this device from India that's not supporting LTE bands in USA. Is there an app in playstore for network unlocking compatible to bands in the U.S. Could anyone please help resolve the issue.
P.S. i updated the device to Android N 7.0 through OTA after reaching U.S.A.
Check your compatibility with Lyca.
