If buying an international data plan or a SIM card for whatever country you visit seems too expensive or annoying, consider renting a mobile hotspot. These devices function as a tether between your devices and the internet, allowing you to connect easily and without sharing the link with nearby users.
The RoamingMan mobile hotspot is an Android-powered Wi-Fi hotspot with “cloud SIM” technology. This means that it gives you data — at 4G, no less — no matter where you are in the world. You’ll have to pay for your data, and the device throttles you after a daily 500MB limit. But at just $10 a day for 4G data wherever you roam, the RoamingMan is useful.
You can rent a device from RoamingMan’s website, telling the company the range of dates you want to use it for, then mail it back to them using a label they include.
First, you should check with your mobile carrier to see if they offer affordable international plans. If not, you should definitely consider a Wi-Fi hotspot.
