You can have 3 active number on your phone as long as it eSIM . But I don’t think eSIM is what I need .

I want to carried my data on my pocket which is physical sim card on my phone .

The phone company can silent your esim or interrupted the service internet in your sim card .. as long as you have the SIM card , you can always recover by changing provider or ..

try to have a look at your physical som card .. Good boy !! Look at it ! That is chip !

If you have not noticed. Chip is the most valuable data storage .
