I recently changed my phone (from Apple to Samsung) about 6 weeks ago and brought my number with me.
Everything was fine up until 2 weeks ago, my old Apple phone is receiving text messages but only from one specific person- they aren't coming through to my Samsung phone. However, if I message back from my Samsung, she receives my messages.
The Apple phone isn't hooked up to a network - I've just kept it so my sons can play games on it.
I really don't know what's happening. Can anyone shed some light on it please?
