My Lebar phone is not sending international sms to bank.

My Lebara phone is not sending international sms to bank. I have topped up pay as you go credit.

Have you used correct region code for bank you are texting

It's sorted now. Lebara customer service had no idea what was wrong. I phoned the bank they advised I shouldn't use WiFi when sending messages to bank, phone data should be used. It did work.
