How can you tell if your phone has a SIM card?
There are a couple of ways to know whether your phone uses a SIM
card.
1. If you know who the service provider is for your phone, and
it happens to be either AT&T, or T-Mobiles, then your phone
does have a SIM card.
2. You could open the back of your phone and look carefully to
see if you see a SIM card. If you do not see a SIM card, then
gently remove the battery from it's compartment and look under the
battery. If you see a SIM card, then your phone does use a SIM
card.
