Came as a post paid AT&T card, but thankfully it did work on AT&T prepaid (No harm No foul)

Works as expected. Changed the SIM online and it came with all 3 punch out sizes to fit any SIM required phone.

Great quality lots of memory, easy to use, thank you!

Placed into unlocked S8 Plus, activated on my existing account.

Thank you Amazon for selling this card. Spent an hour with AT&T trying to get one for my new Samsung Go-Phone (also from Amazon) that used a different size than my old one--for an account and phone number I've had 10 years or more. But I'm in a rural town and their associates are at a loss when it comes to rural addresses and P.O. boxes. So that was an hour of heightened blood pressure. Hung up, ordered this card, went to my existing online account and registered it in less than a minute. Thanx for nothing At&t

Worked in Apple 6. Can be used for Go phone or prepaid. No issues for me. It came with 3 sizes. Not expensive. If using in prepaid situation recommend calling ATT setup

Works flawlessy and is compatable with all AT&T phones. Mine came with adaptors to make it work in any phone.

But once they acquiesced it’s been fine.

Exactly what it says it is. I purchased this instead of others because it is an official att sim card.(Offical cards do enhance network experience) I have proof of that as well. Don't know exactly how or why but 2 exact same devices and 2 exact same plans from AT&T and the device with this official sim card out-performed the device with generic sim card in all ways relating to network (sms,mms and most importantly LTE)....No problems with activation and was shipped well. If I need another I will be returning to this same seller. Do yourself a favor and buy the official.
