A:AnswerHello. You muat buy an unlocked phone/model so you could take it to the provider of your choice. They will activate it and put it under the phone plan you already have. I did this with a couple of phones and took them to Cricket.
A:AnswerHello WiFiCaller, for issues with your phone's Wi-Fi calling feature, please contact your mobile carrier for troubleshooting and information. ^Elizabeth
A:AnswerYes, As of the latest update this phone does have the capacity to announce the latest caller even if you don't have them listed in your phonebook.
