I have recently moved to Mexico and my company provided me with an AT&T sim which works fine with the smartphone provided, but if I's like to switch the same sim chip into my own smartphone (career-free) it's not being recognized by the phone. Please advise how to use the AT&T chip in my career-free smartphone.

Sorry I don't get you. Why do I need to unlock a career-free smartphone? It recognized SIM chips in many European and Asian countries. I understand the AT&T SIM card is locked in some way. Can you please suggest?

Dear AT&T Social Media Manager @ charge,
Can you please provide me general information regarding whether AT&T is locking any sim card for being used in unlocked/career-free devices?

May I ask you to read all the history of this issue to avoid further confusions and misunderstandings?
As mentioned earlier the sim chip is working fine in the AT&T smartphone, but when I am inserting it to my career-free dual sim smartphone (which was never locked) it's not being recognized.

May we please get the wireless number to the dual sim smartphone? Is this a phone on your business account?

I see this last message is not even signed
Again, the dual sim smartphone did never belong to any carrier, it was purchased directly from the manufacturer and the AT&T sim chip is not recognized in it. Can you please analyze the data provided here in the trail and advise?

Since it sounds like the AT&T sim is working correctly in the AT&T device, then it sounds like the AT&T sim is not reading correctly in the other unlocked dial sim device. In order for us to further assist you please provide us the make and model of that device so we can check to make sure it is compatible; which might be the problem.

Thank you for your device information. I just looked up the device, and it seems that this device is not compatible on our network. You can go here http://go.att.com/5975d090 to see what devices are compatible.

The compatibility locator is not able to identify my phone based on the IMEI so I wonder who did you come to the conclusion it's not compatible with your network?
Let me share the Network details my phone is able to handle for your kind verification:
|Technology||GSM / HSPA / EVDO / LTE|
|2G bands||GSM 850 / 900 / 1800 / 1900 - SIM 1 & SIM 2|
|3G bands||HSDPA 850 / 900 / 1900 / 2100|
|CDMA2000 1xEV-DO & TD-SCDMA|
|4G bands||LTE band 1(2100), 3(1800), 7(2600), 38(2600), 39(1900), 40(2300), 41(2500)|
|Speed||HSPA, LTE Cat6 300/50 Mbps|
Do you see any overlap with the network details you guys have in Mexico?
Can you please advise?
