I've been having an odd problem for the last week or so, where my text messages are not received by my mum in the UK. I'm with Spark and my mum is with O2 in the UK. I get her messages no problem.

Trouble shooting this far:

- I've tried texting other numbers in the UK (on the same and different network to my mum) - no problems

- My wife and sister-in-law over here (on Spark and 2 Degrees respectively) have also texted my mum's number - texts not received

- My mum has taken her phone into her O2 shop and then took the battery out, cleaned the contacts and the SIM card, plus had a look at some other settings (not sure what), and said that there was nothing obvious.

This has happened once before and eventually, after a couple of weeks, sorted itself out. In the mean time it's a bit of a pain.

Just wondered if anyone else has/had this issue and has any ideas.

Thanks in advance for any tips. 😀
