Problem solved! I knew it would be something simple! Had another good hard look at my phone this morning & discovered a folder called " Screened messages" & lo & behold there were all the wifes Txt messages! No idea how her number was put in the screened number list, must have been one of those gremlins!! I get a few of them on my computer too!!

I think you need to chage her message center, maybe that's why you don't recieve sms from her, also you can try setting her phone for default settings

Hi Guys, I'm new here so be gentle with me!!! Hopefully this won't be the Dumb question of the day ( or week, or month!!!! )
Anyway I have a 2300 & the wife has a 8390. I can phone & txt the wife from mine OK, but she can only phone me from hers, txt's are never received. She has no problem texting anyone else, I have no problems receiving txt's from anyone else. I'm sure it's something pretty simple but can't put my finger on it! When she phones & txt's my mobile she uses the same number from the Phonebook.
Cheers, KieranT
