Using unlocked Tecno Camon 12 with current ATT plan

Hello, I have a Tecno Camon 12 phone that I've used abroad. I want to use it on my ATT plan in the US, but when I put in the sim card it isn't recognized. Do I need a different type of sim card from ATT for this device or is it not compatible with ATT?   Thanks,   Danny

Unable to add minutes to AT&T pay as you go phone

I am no longer able to add minutes to my son's iphone. I think it's because I let 90 days go by without adding minutes. How can I add minutes, and if I have to get a new SIMS card, will he be able to keep the same phone number?

why is my SIM card taking so long? is it because this is for a prepaid account, and not a regular one?

I ordered a sim card on 8/16 to transfer my phone number from verizon back to you. Does it normally take this long? I'm beginning to have second thoughts about leaving my current carrier now, please advise on when i can expect to receive my sim card.
