Going to Europe and wanting to host Zoom classes in US

[PascalSimon]

I am going to Europe for 3 month and need to hold several 2 1/2 hour Zoom group calls (with video) I have TMobile but I am not sure if this will work. How many GB will each call be and how can I make sure that my calls dont drop? Local SIM card? Google FI? One of those mobile hot spots?  Does anyone have any experience with this? Thanks in advance

Hey @PascalSimon, should have no issue as long as you're able to get service, as Zoom will adjust to your cellular environment; otherwise if connected to a wireless network your connection will be dependent on the wifi, however, should have no issues connecting or hosting. Also, suggest checking with your service provider plan to ensure no extra fees are at cost when using cellular data outside your main region e.x., the US.
