This Android app was created to SIM unlock any Samsung smartphone model.It can be downloaded and installed for free. However the unlocking code delivery is a paid service as we are a distributor for these codes from the manufacturer database.Unlocking codes are assigned by Samsung to each specific phone on manufacturing time so each code is unique for each IMEI (world-wide unique serial of the phone). The manufacturer via the carriers and third-party professional services like ours distributes these codes.The unlocking procedure doesn't require cables, software, or any technical knowledge.Just use this app to order the code associated to your phone. Once you have the code you can unlock your phone only in a few moments. The procedure can be performed anywhere: local or abroad. There is no need to have access to a SIM of the original carrier.We offer a 100% Money Back Guarantee if the procedure doesn't work for your phone.Our app is not hacking your phone in order to unlock it. Also it is not requiring special actions (like rooting the handset)that can void your warranty. We are using only the manufacturer recommended routines for your specific model to unlock the phones with genuine codes. This is a professional service and the very same mechanics & codes are used by the carriers or any third-party certified phone service centre.THINGS TO CONSIDER BEFORE ORDERING:Make sure that your phone is asking for the network unlocking code when you insert a SIM card of a different carrier. For Samsung models there is no other way to insert the code.If your Samsung phone is reported as Stolen/Lost/Payment-Issues it will not work in the country of the carrier that blacklisted it. Before ordering please consult our support department. If it is your case and you still order you will NOT be eligible for a refund.Factory unlocking will not solve the carrier ban. More information about this issue you can find on our website.TROUBLESHOOTING:IMEIs starting with '99' are from CDMA models. Unfortunately we are not able to help you unlock these models. There are no codes available in the database and there is no code entering procedure available.Unfortunately at this point there is no support for Samsung locked by major CDMA carriers (e.g. Verizon, Sprint).Alphanumeric IMEIs? Most likely this is the MEID not the IMEI. The MEID is a serial number specific to CDMA standard. We are not able to help you unlock these models.If your Samsung is rooted and/or has custom firmware installed you will need to revert to stock firmware and apply the unlocking procedure. After unlock as it is permanent you will be able to install any firmware version (custom/stock)and root the phone if you desire.If you receive "Network Unlock Unsuccessful" error when you are inserting the code check the news section from our website (or contact us)for solutions.KEEP UP ON "SIM Unlock for Samsung":For tips and other helpful information visit our website http://www.imei-unlocker.com and follow us via https://twitter.com/imei_unlocker on Twitter, on Facebook at https://www.facebook.com/imeiunlocker or Google+ at https://plus.google.com/+Imei-unlocker.Thanks to all our users for your support and advice!
