AT&T SIM Card, Compatible with Prepaid (GoPhone) and Postpaid AT&T Cellular Service (Nano)

I bought a new phone (Moto G Power) which required a nano size SIM card, and unfortunately my old phone used a micro SIM card. I was a little worried as to whether or not I could activate my new phone online with this new SIM card, but actually it was quite simple. I have an AT&t prepaid account, so I just logged into my account, and clicked on Update Device, and entered the required information. I turned on my new phone and it was activated, no problems at all.

I was glad to be able to get this on Amazon. I went to Walmart & they were all sold out of prepaid SIM cards. AT&T store gave me a rough time because I didn't have the phone with me and they wouldn't sell me the SIM card. So I came home and went on Amazon & ordered this. I had no problem with installation and called AT&T for assistance in setting up the account. Great product!

The SIM card works, UNFORTUNATELY the number that is assigned to it is not checked. I obviously got the number of a woman who owes money to many department stores including the IRS, so I’ve been getting calls everyday from debt collectors. I tried to add a voice message but it cannot be done, so I’ll head to AT&T to see if they can fix the problem.

I purchased a new phone which required a nano SIM. I was sweating how to register the new phone, new sim to my existing AT&T Prepaid account, keeping my existing phone number and account, without creating a new account and/or phone number.I was pleasantly surprised at how easy the process actually was. Go ahead and load the new SIM into the new or existing phone. BEFORE YOU START THE PHONE, login to your existing AT&T Prepaid account. Using the menu icon in the upper Right-hand corner, Go to: "My Device" -> "Update Device", enter the IMEI of the phone (if it's a new device), enter the ICCID of the new SIM on the next line. Save the information, then log off.Start the phone with the new SIM card. The system should automatically register the SIM to the selected device, and de-register the previously associated SIM. My older phone went into "Emergency Calls Only" mode. My new phone responded to my existing phone number. My Prepaid account recently completed it's billing cycle (on "Autopay"), and everything is working fine.

I bought 2 SIM cards in one order. Cards were individually packaged and sealed.Though the sim cards were not identical in appearance (one was blue and the other was orange) they both worked when registered. I got new numbers when I registered online. I had to call AT&T customer service to port my old numbers after registration is complete. I got both numbers transferred for free while I was on the call with the service rep.All functionalities works - call, text, data, and tethering.

The SIM card itself worked well enough, but the number of junk calls received was unbelievable and infuriating.

The sim card actually works well. But what they don't tell you is that everything goes straight to hell after installation and setting up for use. The ATT prepaid site didn't recognize my number and THEY gave it to me. They had absolutely no records about me paying on a plan although I had the prepaid card and receipt. So, I lost that money. Because they couldn't activate the number that they assigned me during sim card setup, I had to pay $10 for a number change and it still didn't work. Finally, I went to a physical location and tried to fix it but it still would not work. So, I had a working phone with no working service for 2 days. Finally, I got someone who was knowledgeable in their field. She figured out that the sim card was the issue. Gave me a new one and told me to never again by from elsewhere. Just find a physical store and do everything in person to avoid any problems.

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
