why is my phone not activated anymore?

[Vanquish1]

I just did a restore and update to 7.0 and now my phone isn't activated anymore. I can't receive or make calls How do I activate my phone now?

Did you log in with your icloud account. If not you might need to sync it with itunes

sounds like your iphone has been unlocked with a gevey sim or something similar. these unlockes support only a specific ios version. so now you have to unlock again. i suggest a imei unlock. you can check where its locked on checkmend.com and find a seller on ebay
