is my phone unlocked incorrectly

[kayshaa]

i have a alcatel one touch 922 smartphone and i presume someone has tried to unlock it but did it wrong because it continues to go out of service for the telecom provider and say the following message *restricted access changed, all voice services are blocked*please help

It is not the phone, it is the phone company's block.
