Name does not appear only number

[9k2hn]

I have Just updated my Iphone 4 to IOS5 and there is one annoying problem is that if any number is saved in the contacts with the international prefix the contact name will not appear and only the phone number, I know that it has to do with the sim card itself (i'm using ZAIN Kuwait). But I want to know if any one else other than ZAIN users came across the same problem.
