A friend of mine just bought an iPhone. She imported all her SIM contacts using the regular method:
Settings > Contacts > Import from SIM All went well.
But when she opens the Messages app, the list is filled with numbers with a country code prefix, so instead of the normal overview of conversations (Tom Dice, David Swimmer, Kim Bauer, etc.), she gets a list with all the numbers of her contacts as name (+324123456, +328945782, etc.).
So, has she imported her contacts the wrong way? Or Iis there some corrupt data in her phone? Or what?
I know it's a pretty vague question without a screenshot, but if you need any more information, please let me know.
