How to unlock AT&T Samsung Galaxy S9 to use with a different carrier

IMEI and other unlock methods for Samsung Galaxy S9 currently on AT&T plan


Samsung Galaxy S9 is among the best Android phones on the market. The device comes out following a huge success of the Galaxy S8. The Galaxy S9 retains what we have loved since the days of the S8, while introducing a huge upgrade. One of the highlights of the Galaxy S9 lies in its re-positioned fingerprint scanner, allowing for more accurate unlock functionality.

The Galaxy S9 is undoubtedly Samsung’s main focus this year to take on Apple iPhones. Therefore, it is not cheap out there, as the SIM-free model will set you back around $719.99, a huge jump over the last year’s handset.

In terms of a US cost on contract, you are seeing around $24 a month for a 30-month period. That’s slightly cheaper when compared to the Galaxy S8. However, keep in mind that if you choose to sign up for a carrier, then your phone is locked. That means that you cannot switch between carriers and use your phone while traveling abroad.

To free your phone, the only way is to get an IMEI unlock. Last year, I owned an AT&T-locked Galaxy S8 and took it by my side during my trip to Cambodia. The minute I landed at the airport, my phone immediately stopped working. After that, I inserted a local SIM card, but I did not get 3G signal.
