I have a question to ask about this eSim. Since I still with physical sim card, haven't switch to eSim yet. Some people say that once you switch to eSim, you cannot do like a physical sim card, just take out the sim card and put to any phone that you like. If we want to change phone, we need to go down to telco centre do scan for new QR code again.

Actually I am planning to switch my physical sim card to eSim because I heard the recent news that Apple is planning to remove physical sim card slot in the future. Nothing is impossible, since last time Apple remove 3.5mm audio jack, remove touchID, remove power adapter, also rumour about removing the lightning port. Probably physical sim card slot will be the next.

So, if I switch to eSim, in case next time I want to replace to another new iPhone. Should I go down to telco centre to scan new QR code again?

I am hestitating about this issue so I search in Google and youtube to find out more informations. I found that actually iCloud can sync and backup our eSim data. So next time we just need to login our appleID in new iPhone to sync back the eSim data from iCloud, is that true?
