What did your carrier say when you contacted them about your invalid sim?
Are you using a supported carrier http://support.apple.com/kb/ht1937
you have got right answer ?
i have also same problem
I am so happy that I finally fix this invalid sim card with iphone4.
What I have:
- iphone 4
- iphone 6
- sim card 1 (invalid for iphone 4, but works on iphone 6. This card's original carrier is from a foreign country)
- sim card 2 (works for both iphone 4 and iphone 6)
What I did:
- put sim card 2 into iphone 4
- Settings -> Cellular -> Cellular Data Network
- Because sim card 2 works for both iphones, then you could see that it has carrier settings like "gprs.carriernameXXX.ch" (e.g. gprs.swisscom.ch)
- Then, keep your iphone4 staying in this setting page
- Remove sim card 2
- Insert sim card 1
- Then you will see the left-upper-corner of iphone 4 is searching for carrier
- Wait and patient, then it works for me. iPhone 4 found the same carrier as "gprs.swisscom.ch" for sim card 2.
- After two minutes, iPhone 4 reminds me to have an update of carrier, i click ok.
I did this, because i noticed that when i insert sim card 1 into iPhone 4, it shows "Carrier not available" in General->About-> Carrier: Not available
Then it reminds me that, maybe I could insert a working sim card to record this Carrier setting.
Because I want my sim card 1 (foreign sim card) working by using the same carrier as sim card 2.
Hope it helps you.

Problem solved! Thank you so much. I was stuck in one country trying to use my sim. This was a lifesaver.
