I have two phone numbers on my O2 account, it would appear that when someone sends a text to one of the numbers, the text shows up on the wrong phone, very strange as it almost appears that the two numbers are sort of mixed up.

Check the apple ID's on both phones are correct.
If you use the same ID on both you will receive duplicate messages.
