Camper WiFi is a solution that gives you access to mobile internet in your camper RV via a 4G router. The 4G mobile router works with a SIM card and its own WiFi network in and around your vehicle. This way you can easily connect laptops, smartphones, smart TVs, and other devices to the internet.
The best solution for this is an outdoor router. This is placed on the roof of the camper RV and offers significantly better range, speed, and stability than standard mobile hotspots.

Since the SIM card router is mounted outside on the roof rather than inside, you have a significant advantage compared to a typical hotspot located inside a camper vehicle. When the hotspot is inside, the camper acts like a Faraday cage, which can limit signal strength and quality.
