No. AT&T is a GSM band carrier, and Verizon is a CDMA carrier. GSM uses a SIM card, and CDMA has the carrier data encoded onto the phone itself. Furthermore, they use different frequencies, so even if you somehow could get one on the other, it wouldn't be able to get a signal.
Short answer: It's impossible.
No you cannot use a Verizon phone on AT&T as Verizon uses a CDMA network (does not require a SIM card) and AT&T uses a GSM network (does require a SIM card). The two networks are not even remotely compatible.
only if you unlock it which is very hard cuz you have to take the phone apart cut 3 wires and put them back in different places in the phone
no because they are two different phone company's.
Buy a verizon phone
no. verizon and at&t phones are not compatible. verizon and sprint phones are locked into their respective carriers.
No the Android does not only work with the Verizon phone plan. Yes one can buy an Android phone and use it on AT&T plan.Be aware that Verizon offers an attractive Family Plan with excellent service.
T-Mobile phones do not work with Verizon's Service. T-Mobile phones use Sim Cards and Verizon does not, so they are not compatible.
The phone will work with any home phone provider such as Sprint or AT&T.
Sometimes... With T-Mobile and AT&T you can used the cellphones offered by these two companies with eachothers service. For example if you buy an unlocked i-phone (which is an AT&T phone) you can use it with T-Mobile. You can do this because they both use the GSM network which requires SIM cards. However you cannot use an unlocked sprint or Verizon type phone with T-Mobile or AT&T because they do not use the GSM network.
verizon cell phones don't use SIM cards and T Mobile does. so in short, no.
N you cant use a t mobile phone with Verizon because it the t mobile phone has a sim card and the Verizon doesn't take sim cards.No you cant use a t mobile phone with Verizon because it the t mobile phone has a sim card and the Verizon doesn't take sim cards.This is not true Verizon does have sim cards look it up!!!!!!!!!!!!!!
No, it is a Verizon phone.
No you cannot. AT&T is a GSM network and Verizon is CDMA. They use different equipment. You can use a Verizon phone on Sprint though.
TMobile and Verizon are incompatible. As are every other two separate phone services. The only way to use a TMobile sim card in a Verizon phone, is to get the Verizon "unlocked". You can do this at most mobile phone shops, but not all of them and most likely not an official Verizon or TMobile shop. This will cost you.
The iPhone 3GS was never offered with Verizon. Most got them with AT&T, and got their phones unlocked so they can use the phone with other service providers.
