If you've ever tried to load Google Maps on café WiFi in Paris or upload photos from a hotel lobby in Rome, you already know the problem. Public WiFi across Europe—whether in restaurants, accommodation, or tourist spots—tends to be frustratingly slow, unreliable, or both. A portable WiFi device (pocket WiFi) usually runs circles around it, and there are good technical reasons why.
Why public WiFi is almost always slower
Public WiFi networks are shared resources. When dozens of guests squeeze onto the same hotel router, or half a café fights for bandwidth on a single connection, speeds plummet. The infrastructure is also often outdated—many European hotels and cafés haven't upgraded their routers or internet plans in years, leaving you with sluggish 2010s-era performance even if the venue advertises "free WiFi."
Then there's throttling and bandwidth caps. Venues don't want guests streaming Netflix or downloading large files, so many deliberately limit speeds or block certain activities. Add weak signals (try connecting from a top-floor hotel room when the router sits in the lobby) and you've got a recipe for wasted time and missed connections.
Security is another hidden speed killer. Safer public networks require login pages, redirects, and sometimes VPN connections that all add latency. Unsecured networks might be faster but expose your data—hardly a fair trade.
How pocket WiFi devices deliver faster speeds
A mobile hotspot connects directly to local 4G or 5G networks rather than competing with crowds on a shared router. You're tapping into mobile infrastructure built to handle traffic across entire cities, not a single building's overloaded broadband line. In practice, this means faster page loads, smoother video calls, and reliable navigation even when you're moving between locations.
Portable devices also give you control. You decide how many devices connect (usually up to five or ten) and you're not at the mercy of a hotel's IT budget or a café owner's internet plan. rentnconnect's mobile hotspot rental lets you pick up a pocket WiFi device for your trip—rent from as little as one day, completely pay-as-you-go with no subscription or long contract. Manage everything through the rentnconnect eSIM app on iOS or Android, and you've got fast, private internet from the moment you land.
The speed difference isn't theoretical. While public WiFi might struggle to hit 5-10 Mbps during busy periods, a decent 4G connection typically delivers 20-40 Mbps, and 5G can push well past 100 Mbps in covered areas. For short trips around Europe—whether that's a long weekend in Barcelona or a week touring Italy—having your own connection simply works better than hunting for the password at every stop.
