=============================================================

If your phone appears with the message "Phone Freeze, SIM unavailable. Please contact service provider" when you insert a non accepted SIM card, then request the 'unfreeze code' from us and follow these instructions:

1. Power on your phone with non accepted SIM inside so the phone displays "Phone Freeze, SIM unavailable. Please contact service provider"
2. Now type the NCK code that we supplied you and press OK (no digits will be seen on display when entering this code)
3. Now phone will ask you for Network Code, so enter SPCK code and press OK.
4. If nothing happens when you enter the SPCK code, you will need to compose code like this: #7465625*638*SPCKcode#
5. Now your phone should be unlocked.

N.B. If phone does not accept the SPCK code, and still have no luck with #7465625*638*SPCKcode# please try step 4 using the NCK code.
