In some cases, yes, you can. But it depends on the service you use—and on the countries you visit. If you go from Canada to the UK, you’re not likely to get uninterrupted service. You’ll probably need to register with a new provider once you get to Europe. Let’s use Starlink as an example of a satellite service you could use. (It’s not the only service that plans to offer portable satellite features, but right now, it’s the best and most popular option for most digital nomads.) Starlink now offers a feature called Portability. For an extra $25 a month, you can schlep your satellite dish with you when you cross between countries on your resident continent. However, you aren’t guaranteed a certain level of internet service everywhere. Service depends on the Starlink coverage map, and you won’t necessarily receive prioritization outside your registered address. So if you want to continent-hop, one satellite service isn’t going to do it for you. You’ll probably need to sign up with a new service for each continent you visit and sometimes each country. Long answer: if you’re in the United States and want to travel to another state with your service, that should work fine as long as you have a portable satellite service and not one tied to a certain address. The same should go for other areas with a single internet-governing body (like the Federal Communications Commission in the US). For instance, if you’re in the European Union using an EU-approved portable service, you theoretically shouldn’t have a problem moving between those 27 countries. Make sure to compare the fastest and slowest internet speeds across US States.
International borders: Maybe, depending on your service and what countries you plan to travel to. Domestic borders: Probably, as long as you have a portable service.
