For the last two hours I've tried the 789, 150, and SMS routes and so far haven't found a solution. In particular SMS seems to be a very dim AI app which repeats questions and hasn't respond for over 30 minutes.
The battery in my older phone is on its last legs so I now have two Android phones. I tried using the SIM card from the old phone in the new phone but no joy. So I conclude that I need (new or replacement) SIM card..
I'd like to keep the old phone for emergency use. If I turn off power greedy like GPS/Location it's fine.
