Using a Verizon S7 edge on T-mobile in Europe

[AC Question]

I have a Galaxy S7 edge that I bought on Verizon, but recently switched to T-mobile. I've been using the same phone on t-mobile and it seems to be working fine for me, even though the bands aren't exactly the same as a t-mobile version of the S7 edge. However we're going to Europe for a month in September and I'm looking forward to being able to use t-mobile while there and not having to get another SIM. But I'm not sure if or how well my version of the S7 edge will work in Europe. I'm technically on t-mobile and have a t-mobile SIM but it's also technically a Verizon S7 edge.
