Hi I'm a mobile phone Tech.

If your mobile phone is on a contract with a service provider, most of the times it will be locked in with them for the duration of the contract,
So if you try to insert a sim card from a different service provider, it may say "sim card not valid'
Try to insert your original sim card and see if that works.

Otherwise if this IS your original sim card and all of a sudden this message "sim card not valid" has appeared, then the sim card has gone faulty and you need to get a new sim card from your service provider eg... Vodafone.

Hope this is helpful
