I'm going to be showing you how to use any smartphone with AT&Ts go phone service.
The first step is to make sure you have an unlocked smartphone compatible with the GSM network when you buy a smartphone unlocked you are paying for the full price of the phone, and you earn the freedom to choose any plan you want.
Can choose either the GSM or the CDMA network
You can choose to buy an unlocked smartphone compatible with the GSM network, which will work with carriers like t-mobile and AT&T or you can buy a smartphone compatible with the CDMA network, which will work with carriers like Verizon and Sprint.
Once you choose either the GSM or the CDMA network you can easily switch between plans and carriers. For instance, I have an unlocked iPhone 5 compatible with the GSM network, and I can easily switch between t-mobile and AT&T just by swapping out my SIM card to activate you unlock the smartphone on AT&Ts go phone service.
