T-Mobile sim in my unlocked Verizon 5S

[Zo6]

Just wanted to try the coverage in my area for Tmobile with my Verizon iPhone 5S by just sticking in a temporary sim card and number. Will that work without doing anything with Verizon?

If the phone is unlocked it will work as soon as you pop the sim card in. I am not really sure how you will get a "dummy" sim that has cell service without starting a line with tmobile

A member borrowed a sim card from an AT&T or T-Mobile store to test the coverage. I think you can probably do the same, unless you already have an active one from a friend, etc.

U can pay also. 3/day tmobile

Yep, your phone is already unlocked.
Not sure what the best route is for trying T-Mobile service though.

It's plug and play.
