Both my parents have SE phones (k750i and s500i), both on T mobile PAYG, and a few days ago on my mums phone she kept getting "network busy" whenever trying to phone anyone, it still hasn't gone away, now today the same has happened on my dads phone.
Funny thing is i have a k800i and also on T mobile PAYG, but I haven't had this problem occur (yet), i tested to see if it was an issue with their sim or phone by inserting their sim onto my phone, and wala it works fine, put my sim into their phone and it doesn't work, tried on another phone too an old panasonic and t mobile mda and their sims dont work on those either.
Anyone know what the issue could be? seems rather odd
