Review on AT&T ATT SIM Card Kit (2 Pack) - Authentic Micro/Nano/Standard GSM 4G/3G/2G LTE - Unactivated Prepaid/Postpaid Starter, with Talk Text Data & Hotspot - Includes Free Tray Removal Remover Eject Pin Key Tool by Julio Montano

If there is an instruction manual I would give this card all 5 stars. Without proper maintenance, the product failed several times. I want to write some important points for using this map, seller please. 1. Search Google for "at&t prepaid activ", go to the official at&t.2 activation portal. Never, ever, ever take your card to an AT&T store to ask for help, even if you were unable to activate it online and the website says you should go to any AT&T store for help receive. People in the shops will just say the card doesn't work and you need to buy their card. It is not true! 3. You need a credit card or top-up card to purchase a plan once activated online. The billing address requires a real US address, but does not have to be your address. Since it is a prepaid tariff, no invoice is actually sent. Some plans are only available online, which is a lot better than the plans you can pick up in stores.
