Only solution to fix this is by unlocking the phone, you can do this online at or go to an professional Unlock Shop.

for the online unlock service you need your factory data-cable that comes with the phone, everything is specified step by step at the site

this server can remove phone-freeze and simlock in 1 click

I noticed that lot of people facing the same issue.
The phone has been bricked due to incorrect insertion of unlock code three times in a row. However you can get an unfreeze or defreeze code online and unfreeze the phone, there are sites that do offer this service along with unlocking codes. I have successfully unlocked y Samsung Gravity 2 using Samsung unlock codes. You can also check other forums and Google for this.

SOURCE: My phone says: phone freeze, sim unavailable model

OKAY, Ignore the posters saying that you need to buy a 'freeze code', the truth is you don't. If your phone has 'phone freeze. sim unavailiable' please enter in *2767*3655#. After you do so the phone will restart and will work with your sim inserted. I hope this solves your problem.

Kind Regards,
