This is a good Wi-Fi roaming option as opposed to a monthly fee. A little pricey but cheaper than paying for Wi-Fi roaming with major providers. Here's how Roamwifi works: You buy a pre-installed device that's good for say 90 days and 100GB, whichever comes first. Now 90 days doesn't start until you use it. The downside is that even if you don't use it for a week, for example, it won't stop. Customer support is almost non-existent, your best bet is to ask a question here. They say to email service@roamwifi.com for help but when I had a question they never responded. To connect, press and hold the power button for 3-4 seconds, a butterfly will appear, find an available network, select to get your SSID (acts as your login) and password, and press the once power switch. There are a few decent YouTubers who go through this. Speeds aren't as good as your home network, but decent depending on where you are. At least for a person connection. Keep in mind that this isn't a satellite phone, so there's no cellular connection (they use T-Mobile and AT&T in the US), no Wi-Fi, but most places under 7,000 feet usually have one of these two networks. So a total of 4 stars from me.
