Traveling with AT&T Samsung TAB 3 7.0 LTE


Traveling with AT&T Samsung TAB 3 7.0 LTE

How to I unlock the device to use oversea (mainly in South East Asia countries)?   I bought the device from Bestbuy at full retail price and no contract.


I thought the device was already unlocked since it was no contract.   I put the AIS Thailand SIM in and I got the error "Network Locked SIM Card inserted".


I tried AT&T self unlock web service but I can't progress any further because I have to enter the phone number and IMEI in to the form.   


Could someone point me to the right direction to get this unlocked please?





AT&T wireless customoer since 1999

Thank you for the reply.   I should not have the difficulty unlocking the device but I am.


I returned the device already because AT&T rep told me I can't get this device unlock as I have not met the requirement.


Below is what the AT&T agent told me...


Me: Hello


AT&T agent name removed: Hi, I see you have a device unlock request then today..


Me: how do I do that. We are traveling on 12/25/2013 to Thailand and Vietnam.


AT&T agent name removed: and which line is this that you want to unlock?


Me: Not phone, just my tablet Samsung Galaxy Tab 3 7.0 from AT&T


Me: I just purchased it last night.


AT&T agent name removed: Thanks for that. and the phn number on the device?


Me: I already have an unlocked phones I use for travel.


Me: This is the problem I can't use the self unlock service on the web site.


AT&T agent name removed: Yes-- I need the last 4 of the device phn number..


Me: This device is brand new, no contract. Therefor no phone number associated with the device.


Me: Ummm, no number.


Me: An AT&T number or number of *ANY* SIM card?


AT&T agent name removed: I can not unlock a device where there is no line of service attached to it. The device needs to be under contract for 90 days with AT&T service before it can be unlocked according to AT&T policy. Have you read the terms and conditions for unlock requests on I believe all of this is spelled out there... 


Me: THis device paid in full retail not subcidy device.


Me: And if you look at my account history you will see I am not going anywhere.


AT&T agent name removed: I understand. The terms and conditions of an unlock state that the device has to have been activated and in service on AT&T before it can be unlocked. This is just AT&T policy....


Me: Wow - just wow.


AT&T agent name removed: I know, policy is not very flexible in this case... 


Me: MAybe it's time for me to going somewhere.


AT&T agent name removed: We would hate to see that! I have no latitude on this policy....


Me: Oh, well. I guess I can't get this thing unlocked so it going back to bestbuy.


Me: So me and my 3 lines once contract is over.


AT&T agent name removed: I am sorry to hear that.
