Not sure that the cell connection will be strong enough to stream seamlessly (but I could be wrong). It also drains your battery faster. I suggest getting a mobile hot spot like my fav Verizon's Mobile Hotspot brands. I moved a lot when I was with my military ex and anytime I needed to wait for a cable set up, I'd use the mifi mobile hot spot.
I streamed on SM for a few hours a day and I think the upload speed was 3mbps(4G LTE Speeds), which isn't amazing; but it gets the job done and I had no lagging or complaints. Clear stream the whole time. You can use it anywhere there is Verizon coverage. The only issue I had was that it eats a lot of data when you stream (obviously) so you might be paying $300 to refill it for say 1 week or less if you can't stretch out your data. I say streaming 2-3 hours per day is probably max or you'll eat through it fast.
If you're going to be in Europe I've heard good things about the pocket wifi called My Webspot. They deliver it to you, you use it, travel with it, and return it before you leave. They have them in Europe only.
If you can, I suggest staying in airbnbs and ones that have strong internet connections. Before I stay in any rentals, I make sure the host has high speed net and they will answer any question you have before booking. Most will say so in the ad.
Just in case, bring your back up (mobile wifi). Just make sure you're okay with shelling out $200-300 for the product and the data. There's nothing really unlimited out there (I think sprint has something?) so once you run out of data, you'll have to add more- but it def works with cam.
This one has great reviews and can be used internationally/globally.

This has an unlimited plan, but it's 4G speeds up to 10G and then it drops to 3G speeds after. Or- anywhere from 5 Mbps-12 Mbps download speeds and 2 Mbps-5 Mbps upload speeds. So decent for cam and unlimited depending on the plan you want.
