Recently broke my Iphone X and my wife has an old IPhone 7 I am using. Model is an A1778 and I got it unlocked by ATT. I can make calls, have data and send imessages. MMS messages do not work, I cannot send or receive.
I know that Verizon Iphones do not have the option to enter these manually and not too many people are familiar with them. Both of the Verizon stores I have went to do not know anything about them.
I am hoping to have some luck here so that I can get MMS messages until I decide what I am going to do with my broken phone
