I have used a 3 Phone which has been great until a couple of months now. I have problems receiving SMS from abroad (especially Russia - and this is quite serious since my girlfriend's family is from there!).
Specifically, 1. I don't receive any messages (some of them very, very serious and urgent messages... such as girlfriend's parents visiting :-( ) 2. Or I receive them Protected content later, but this happens rarely.
Before this problem started, 3 worked very fine and I have been using it for 4 years now.
I am considering to buy a new phone, and maybe also a new operator.
Any advice on what is good and reliable for international texting (both sending and receiving)?
