I am in Australia with Boost Mobile.
Purchased a Samsung S21 Ultra outright (upgraded from S10 outright).
Have remained with Boost Mobile.
Samsung chat worked perfectly with my S10. But keeps saying registration failing with my S21 Ultra.
I have cleared cache etc on Samsung Messages.
Even when trying to set up Google Messages it keeps saying trying to register.
It's not the end of the world, it's just annoying something so simple isn't working.
Hopefully can get some help please.
