I'll be in Geneva, Switzerland for about 8 hrs on a layover en route to Barcelona on May 11 - and I'll have my TMO S7 Edge with me. I am currently on a family plan and on the TMobile-one plan.

What are my options again for internet? Is it unltd or up to 5 gb at lte then a sloooowwww gsm type of connection the rest of my time out there?
