I recently traveled to California from Ireland with my phone. Purchased and esim before going. First two days here all working well until, my phone decided to tell me my sim cards where not working, neither esim or physical sim.
I literally don't have access to anything in sim manager as it is all greyed out. A message keeps popping up about the sim card tray. I can't seem to find anything online to help. No new apps on the phone or anything like that. No changes. My boyfriend tried my sim in his phone (same phone as mine) and the same thing has now happened to his! No phones and we are on a road trip across the States 😩 we have tried all the usual stuff. I know the basics. Other than that. I'm stuck!
Does your carrier cover international use? Most carriers require a separate plan or add on regardless what sim you use. You also need to make sure you have the correct charging adapter. Also did you change the time zone on your phone
