Just got a Samsung Galaxy Tab 10.1 and used Galaxy Tab Unlocker app to do a SIM Unlock so I can use my AT&T SIM in it but when I go to Network Setting\Mobile Networks\Network Operators and scan 2 different AT&T options show up and neither one will allow the tab to get online. One of the options says it's registered the network the other says Sim can not be registered to the network. Is there something I'm doing wrong? How can I check if the App really did a SIM Unlock? The app I used say's the SIM is unlocked. The tab is rooted and running OTA. Any and all suggestions would be appreciated.

Hi guy's, have a UK SGS2. It's rooted and running Criskelo ICS rom. I've recently been in Brazil for 6 months, my phone worked fine over there. I've come back to the UK and got a standard Vodafone PAYG sim card. When I try and use it the phone says "not registered on network"
The sim card itself is fine as it works in my old mans SGS2.
I have wiped the phone and installed the standard software and it's still the same.
Anyone got any ideas what could be up?
The phone could be network locked (sim lock)

That's what the guy on Vodafone web chat suggested.
How and why would it get network blocked?
The phone was originally on the 3 network. I bought it 2nd hand about 1.5 years ago and it's been fine on T-mobile ever since.
If it is sim locked, is there a way to unlock it?
You can unlock with:
https://play.google.com/store/apps/...sImV1LmNoYWluZmlyZS5zZ3Myc2ltdW5sb2NrY29kZSJd
It's free on google play.
I don't think it's sim locked, I can put any chip in it. It doesn't ask me for an unlock code.
I have run the sim unlock tool. The code it came up with is 00000000
When you go into the network settings, it shows all the service providers. every provider I click on says "can't register on the network"
I'm wondering if i've had some sort of network update in Brazil that's screwed it up?

I'm sure its something to do with being abroad as i've read about someone that had the same issue when they went from China to Denmark.
If I go to settings - phone it says...
Network - Unknown
Signal Strength - 103 dBm 5 asu
Mobile Network Type - HSDPA:9
Service State - Out of Service
Roaming - Not Roaming
Mobile Network State - Disconnected
My Phone Number - Unknown
IMEI - the correct number, I checked
The fault isn't with the sim card itself, I can use it in other phones and I can save a contact to it in this phone.
I'm wondering if some of those network settings I had from the Brazilian phone company's have messed something up.
Hello all,
I have been unable to find a clear answer to this question--I hope you will bear with me:
I have a Galaxy Note 2 from Verizon running Android 4.3. Before leaving for a trip to India this week I confirmed with Verizon customer service that the phone was unlocked. In Delhi I purchased a local sim card (from Airtel) and inserted it. Voice and text work perfectly but the data plan does not. The sim works when inserted into other phones but not in this one. The Airtel techs cannot figure it out. I have access to the APN settings under the Mobile Networks menu and have edited the Name, APN, Server, APN type etc. as indicated by Airtel but no dice. When I go to "Select" it finds Airtel after some spinning and when I select Airtel from "Network Operators" I get a "registered on network" message but still can't get data.
Is it the case that Verizon locks the data on this phone? Is there any way for me to unlock this from India? I don't really know anything about rooting phones.
Any help appreciated!
I also use the same handset in India and use other operator sim...no trouble so far in data
Sent from my SCH-I605 using XDA Premium 4 mobile app
I am having some issues making the switch and needed some help.
I purchased my Galaxy S2 from AT&T awhile back, rooted and installed task650's AOKP rom after I had issues with the ICS update, and have been running the latest build happily ever since with no problems. After my contract was up I got an unlock code from AT&T, purchased a sim from AIO and installed it. The phone booted up and never asked for the unlock code. I am able to make and receive calls and texts, but mobile data doesn't work. WiFi works just fine. I installed and ran GalaxSimUnlock and Galaxy S Unlock. Both programs indicated my phone was unlocked.
Is this an issue with AIO? The signal bars say AT&T on the phone, but I just assumed since AT&T owns AIO this was normal. Do I need to install a different rom and try to unlock again? I am going to try and track down a sim from a different carrier and see if that works. I have tried dialing *#7465625# to check the unlock status, but it returns the error "connection problem or invalid mmi code".
I have searched for answers, but I am clueless. Any help would be appreciated. Thanks!
Sounds like your APN settings are not configured correctly with your new sim. Go into your APN settings and let us know what is set.

Here are screenshots of the only settings I could find.
I went on aio's site and found how to manually enter APN settings.
Followed the directions and all seems to be working now! Thanks for pointing me in the right direction!

Hang on to that unlock code. When I moved from AT&T to Net10, my phone didn't ask me for an unlock code either. Net10 and AIO both use AT&T networks. But when I went to Canada and bought a local SIM there, it asked me for the code. Luckily, I had saved it.
Hello,
I have a Verizon Galaxy Note II (SCH-I605). It is stock running 4.4.2. I left Verizon and have put a GSM sim card from a local rural cellphone provider in my phone. The phone seems to work great. No issues with calls, sms, mms, or data.
I do have a constant notification that says "Phone Activation" "This SIM card is from an unknown source". Is there any way to get that removed or will it stay because it was originally a CDMA phone?
Thanks for the help! You guys are the best!
Hello, so I recently left my carrier, Boost Mobile. So the phone is locked to their network and they won't unlock. But within my apps list is an app called Network Unlock. Any idea how I can get it so show itself on my main screen? It seems to be hidden.
