A:AnswerYou can purchase it unlocked as I did and mine cam with a Verizon sim but all you have to do is remove that sim and put in your own or transfer your number through your carrier to the e-sim and use a secondary physical sim for a dual sim phone....
A:AnswerAn unlocked phone allows you to go from carrier to carrier by just changing the sim card. If the phone is locked, the carrier has to unlock it before you can change carriers and this can take days. Locked phones have always been a deterrent from changing your carrier. If you purchase/upgrade your phone through your carrier you cannot get an unlocked phone. These are sold through stores like Best Buy.
A:Answeryes but there are caveats since American networks will charge you a service fee of approximately $70 a month for international data. Google Fi is an international sim and works here or overseas. Do your research on companies that support both stateside and international data without charging extra. Your iPhone 11 is a dual sim phone which can be set up to use 2 different networks as I have done. I use Google Fi (physical sim) which can be used here or overseas and Verizon (esim).
