Contact names dissapearinng in messages

[LayneeMarko]

Hi folx..

I have a problem.. Occasionally my contact names are disappearing in messaging app.. So when I have a conversation with John for example, sometimes when I enter messaging i see johns number, instead of his name ( and it's not imessage it's regular sms).. Then, right from sms thread i enter contact info, tap edit and tap done, and name is back again.
But it will disappear again sometimes.. Sometimes not..
Any one can help me?

Thanks in advance

Are you getting any notifications that your SIM card is loose or becoming disconnected? I had this happen on a phone before where my SIM card kept jogging loose and it'd turn my contacts into phone numbers for a couple minutes. Might want to open up your SIM door and see if there's any dust or anything wrong in there.

Any one else with new suggestions?
