Unlock AT&T G3: Is T-Mobile Only Other Option?

[bossfan61]

Just received the unlock code from AT&T for my LG G3 (D850). If I choose to unlock it, is T-Mobile the only other option or can I use on Verizon or Sprint?

Thanks!

No VZW or Sprint. You can use it on Cricket and Straight Talk with their GSM services.
