dual sim
can anybody help me . I’m not very tech savvy .last year I bought a new iPhone 17 pro . Normally I would go to the shop and get the Apple tech to set it up for me . But this was sent by post . I went on Holiday and set the phone up myself late it night when I was tired . I put the sim in and followed the instructions. Everything worked well but I could not send texts . When I came home I went to the Apple shop and the man said I had set the phone up With dual eSIM . He deleted one and then I went home. But the problem continued. Sometimes my phone would send blue iMessage sometimes it would change to green texts with no apparent pattern . This was causing me problems which I wont go into. Eventually I went back to the apple shop and saw a different technician. After 10 seconds he popped open the drawer on the side and said you have left your physical sim in . (I thought your phone needed a physical sim ) I’m now being told “you can’t have 2 sims with the same number , one would cancel the other out “ I only know what the apple tech told me . Can anyone explain ?
