Please check carefully if your order to unlock Samsung Galaxy S2 handset fulfills the following:

  1. Be sure that your phone is SIM locked. Insert another network SIM and wait for the unlocking message to be displayed. If your phone doesn’t show any unlocking message and if it works with another network SIM, then your handset is NOT Sim locked.

  2. Be sure that you send us the correct IMEI. There are 2 ways you can get the IMEI of your phone. The first one is by dialing *#06# on your phone. The second one is to check the sticker underneath the battery of your handset. The IMEI is a 15 digit number that is unique for each handset.

  3. Be sure to choose the original country and operator – NOT the one you wish to use it on! There are certain operators in certain countries that sell phones we can NOT unlock.

If you place a wrong order by not fulfilling the requirements above, you will NOT be eligible for a refund. We support the cost for each IMEI we try to unlock, that’s why if we generate a code for a wrong IMEI or a wrong network, we are not able to send your money back.
