call on other devices
So i have an iphone 13 but in my country i cant use my sim because i have to get it pta approved and that costs to much, so i was thinking about getting iphone 5s for calls on sim.
The questions i have are
•Will call on other device work if any one of devices dont have internet
•How long is the conectivity range
•Can i place a call on the phone that doesnt have sim and network
p.s i am not talking about calls on facetime or any type of internet call, i am talking about sim calling
