I have bought a Samsung Galaxy A51 in mexico and I have used it since. However, I moved to uae for my studies. It seems that the eatisaalat SIM card is not working with my phone and region locked massage for me, I can't send texts, or make calls. How should I proceed ?
All the Samsung phones come with an active regional lock when first bought. Assuming it's not also locked to a specific network, using a SIM from the same regional origin as the phone for at least 5 minutes of total talk time will disable the regional lock and allow you to use a SIM from any other region.
