If you want to buy a Samsung Galaxy S8 and do not know if the device is Simlock and Netlock free, then you should absolutely test this before the final purchase. The situation usually occurs when buying via eBay etc.
You are on site with the seller, but he does not know himself. So that you do not buy a Samsung Galaxy S8, which is blocked with such a lock, we show you now how to test this easily:
Insert your own Sim card
Take your own Sim card and put it in the Samsung Galaxy S8. Now test whether you can use the phone and Internet function. If this is possible, then there is no Sim or Netlock set.
If the phone does not work, then the smartphone is busy with a sim or netlock.
To remove this lock it usually costs around 100 $, so we recommend you to buy the smartphone only if the seller decreases the price fot this amount.
We hope that you have good luck with your preused Samsung Galaxy S8 and you will enjoy using your smartphone.
