If you wish to get a free unlocking for your Nokia C3, you need to get the unlock code, so you have to contact your phone carrier that is locking your the phone in this moment, because it is the only way to obtain the SIM network unlock PIN for free. You must know that you need to fulfill the carrier's requirements, such as being the cell phone plan owner. Our company is dedicated to calculate unlocking codes by IMEI, we work with official unlocking servers and we send the same code as the carrier.
The easiest way to unlock a C3 is to get the official unlock code thanks to our Nokia servers, when other SIM cards are inserted, and your Nokia C3 asks you for the code; you must fill out the questionnaire and in a few hours you will receive an email with the unlock instructions.
It is important to note that a Nokia usually has five attempts to insert the unlock code. If the attempt counter is zero, our unlocking code will not work on your C3. The solution will be to reset the mobile phone by cable, but it has a higher cost depending on each model.
Certainly not, our unlocks are official and forever, you can update Android without any problem.
Unlocking method is for any SIM card of Bell Mobility, Chat'r, DMTS, Fido, First, Globalstar, ICE Wireless, Freedom, MTS, Rogers, SaskTel, Telus Mobility, Videotron, Wind, Koodo, Solo Mobile, Virgin Mobile, Mobilicity from Canada and any other country.
When a C3 does not reject your new SIM card but does not allow you to make calls, it is most likely that the IMEI has been blacklisted. You need to contact with the carrier to solve it.
