If you want to get the unlocking code for your Oppo A77, we recommend you to contact to the original carrier, 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. At Movical.Net we know that sometimes it is complicated to fulfill these requirements, if your device is a second-hand phone or if you are in another country it will be a really complicated task.

It is important to note that a Oppo usually has five attempts to insert the unlock code. If the attempt counter is zero, our unlocking code will not work on your A77. The solution will be to reset the mobile phone by cable, but it has a higher cost depending on each model.
