How to Unlock iPhone 7/7 Plus for Different Carriers

Transferring carrier service on an iPhone 7 can be challenging if you use a GSM only model. Sprint and Verizon variants can be used on any unlocked iPhone 7 because they accommodate both GSM and CDMA sim card technologies, while the AT&T & T-Mobile versions lack CDMA chips. If you want to use your iPhone without carrier restriction, below you will find how to change carrier for iPhone 7/7 Plus.

Part 1: Official way to switch carriers on iPhone 7 (Plus)

Most carriers use GSM (Global System for Mobile Communications) SIM card technology. Unluckily for iPhone 7 users, you cannot use a Verizon or Sprint SIM card on a GSM iPhone 7 or 7 Plus. Other iPhone models like iPhone 6 and 6s can take all cards. Carriers in the U.S lock iPhones to their SIM cards, and you cannot freely change iPhone to another carrier without unlocking, e.g. an AT&T iPhone rejects a T-Mobile card. This is common for phones bought on contract to ensure the carrier recoups the subsidized prices.

You can try unlocking your iPhone by directly calling your carrier and telling them you’re having trouble switching iPhone carrier. Most carriers will unlock your iPhone if the contract has already expired. Request it to be unlocked if the contract is null and all bills have been paid in full. If you are travelling and will need to change carriers, inform them on the call to have it unlocked. You might be charged a fee, but it is worth paying. It is also possible to unlock the iPhone yourself.

Tip: You might receive a message saying “The SIM card inserted in this iPhone does not appear to be supported.” after unlocking. If so, please restore your iPhone to factory settings or consult your carrier to confirm whether the unlock process is successfully applied.
