You must determine yourself if your handset can be unlocked before purchasing as this money cannot be refunded if you did not check first.  The easiest way to do this is to insert a sim-card of a different network provider that your phone is not locked to.  If your phone ask or prompts for a network pin or unlock code this means your phone is supported for unlocking with a code.  

It is our terms and conditions that factory codes are not refundable.  It is the policy of our supplier that by no means can codes be returned for any reason.  Unlimited assistance can be given to help resolve issues with errors and bugs.  Also if the phone is blacklisted the code will be of little use to the buyer as the phone will still likely not work on FRANCE  networks.  We cannot be held liable for codes that do not work because of phones being blacklisted or any other error.  By making this purchase you acknowledge the code cannot be returned or refunded.  We hope that our reputation and reviews of past purchases will bring you the reassurance you need to know that you will receive your phones accurate unlocking code from the factory database.
