SOURCE: country code

Your Canadian provider locked the phone, so that you may only use their SIM-cards in your phone. This is common practice. Consult your old provider for the unlocking code and instructions, the other solution is to take your phone to a proffesional unlocker and have him unlock the phone for you. Only problem with that is that the warranty on your phone might be void after doing that.

Un-Clocked is temporary, allows free txt and calls for a few minutes.
Un-Locked from a network is what will allow you to use any sim card on your phone.

Hi there,i had purchased htc thunder bolt a month ago from Miami US and since it was a lock piece i also bought unlock code online.Now the biggest challenge i am facing is when i put my local active sim...


Hi, i think your step not correct when entering HTC Thunderbolt unlock code. You must use your old sim card to unlock your phone, don't use new sim card before that phones completely unlocked. That's why your sim card not recognized. If this method not working maybe you get wrong HTC unlock code, since it's little rare for me. Usually if you bought unlock code reputable online store, they usually send unlock code with complete instruction how to insert that unlock code in your phones. The bottom line try my method and if not working get new code. Thanks.

NB: don't enter your wrong code to many times in your phones, it will caused your HTC to hard locked state and you can't use that phone even you put your old sim card.

I have downloaded the f secure to my mobile phone and locked my phone by mistake. now i can't unlock my phone because i don't have the default password.


Had same problem with Nokia N8. I removed SIM card & held on/off button & menu button(bottom right hand corner front of fone) for about 15secs until fone switched off. I then reinserted SIM card, switched on fone, entered my SIM (not F-secure) password & haven't had a problem since ! P.S. I also removed the micro sd card til fone was working correctly so as not to risk losing any data. Hope this helps...

My Samsung M3510 shows phone freeze


Now the only way you can do it is to contact your SIM provider , Call them and ask the PUK code , they will ask you some questions regarding your perivours balance and all that , try to use it and it will work , but if it does not work , then buy another SIM and ask your telecom provider to issue you on the same number ! This the way you can do it
