activation server

What error are you receiving?

"We're Sorry, Activation Server Temporarily Unavailable, contact Customer Care?"

99.9% of the time, the cause of this issue is the fact the phone was jailbroken/hacked to unlock it for use on networks other than the network the phone was originally locked to. Apple maintains a database of officially unlocked iPhones, and when Apple's servers detect phones such as yours, activation stops & you get the message you got.

So, either get a sim card from the carrier your phone was originally locked to, or get it officially unlocked, if you want to activate it. Because it appears that it was not officially unlocked.

The phone is unlock, i think problem with icloud !

I used right ID and PW but it keep saying wrong ???
