I have a LG V40 thinq that was paid off some time ago.  I am preparing to sell the phone and need to verify it is unlocked.  How do I do that if I’m no longer a T-mobile customer?

The easiest way is to insert another carrier’s SIM and see if the phone objects when it boots up.

Another way is if the phone has the unlock app you can use it to check.
