When i go overseas to get temp sim it ask me to provide password from sms.
But doesn't receive sms.

Simcard size different from my Ip6 cannot interchange

Any ideas?

cut sim to nano, use ip6 get password, use sim adapter put back in ipad. that's what i will do if needed

that manual option i've been doing
i thought i could install some app to get it working
in theory if it is 3g capable it should work
