HI I changed the number that came with the phone to my existing mobile number, but the phone keeps switching from one number to another. i have spoken to o 2 twice and it's not resolved what do I do? Any ideas? Do you think they will try and charge me for 2 contracts?

thank you xx

Go to Settings then Phone and change the number at the top to the one you are keeping. Let me know if it had the old number there?

I'm having the same problem, under settings and phone my number was the new number I've changed it to the number I've asked to keep now. My phone receives texts from the number I wanted to keep but replies with the new number 😕 help please?
