No.
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.
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.
No, just a carbon copy of the AT&T iPhone, but on Verizon's network
No. they use completely different networks, Verizon uses CDMA, and att uses GSM, there are some Verizon phone how ever who do use the GSM, network for international call, i don't see that being an issue.
In order to unlock an AT&T HTC Inspire 4G Android Phone, you will need to contact AT&T direct. Alternatively, you can utilize software to enable unlocking of the phone.
AT&T. But you can "unlock" an iPhone for verizon.
In the US, it is available on Verizon and AT&T. There are also ways to unlock the phone so that you can use it with any SIM but I don't recommend this.
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.
No. Cingular/AT&T use the GSM network and Sprint uses CDMA. A Verizon phone could be used with a Sprint plan but Verizon customer service will have to give an unlock code.
There are a number of carriers that supple smartphones with Android. This includes Spring, Virgin Mobile, AT&T. However, my favorite place is Verizon.
Yes, you can use a Samsung Galaxy S3 or S4 that is on AT&T or Verizon network on a Straight Talk plan. You will need to unlock the phone before switching providers.
Makes the phone available to use under all cell phone companies.. example: The Apple i-phone (AT&T) was unlocked before I bought it, therefore I can use it under my Verizon Wireless plan.. explanation: Verizon Wireless does not have the i-phone
