Note 10+ Unlocked Already?

[elie2wins]

I have a half paid off Note 10+ from xfinity, that looks to be unlocked already.

I swapped to a friends T-Mobile sim and was never prompted to enter an unlock code. The boot splash/log screen also updated itself to T-Mobiles. 

Any idea why this occurred, or would i need to maybe test with At&t as they are purely gsm?

Try to place a phone call with your friends T-Mobile SIM card.  It it completes the call, then it is unlocked.

Yea I did that too and the call was successful

That's your confirmation that it is unlocked.

$40 for nothing on two fronts.... i was going to do the Samsung trade in program, and just pay off the phone, but i learned those phones dont work anyway...and now i dont actually need to unlock the phone
