Not support postpaid
Not letting me transfer.
Prepaid ONLY. Doesn’t work for post-paid accounts.
If you downloaded this app thinking your phone would suddenly be able to move your postpaid line from your physical SIM to your eSIM... it won’t. (15-Jan-2019)
Not what it should be
It does not allow moving from physical SIM to eSIM. Disappointment!
With Family Sharing set up, up to six family members can use this app.
