I bought an iPhone 6S a few months back. The seller advertised it as the AT&T model, but assured me that it would work with T-Mobile (my carrier). It did work on T-Mobile, but now I am looking to sell the phone again. However, I am unsure whether to list it as "unlocked" or just a "GSM" version of the phone. Since it appears it was not locked to AT&T, is it safe for me to market this device as "unlocked"?

If it was still locked you never would have been able to use it on T-Mobile.

Locked means locked to carrier, not type of network.
