Getting online the moment you land used to mean hunting down a local SIM shop or bracing for a nasty roaming bill. Travel eSIMs have largely solved that, and a new wave of budget providers is competing hard on price. The travel duo behind Hopscotch the Globe recently put one of them, MobileSIM, through its paces on a trip to Montenegro — and came away impressed.
For anyone still new to the concept, an eSIM is a digital SIM you activate directly on a compatible phone. There's no plastic card to swap and no queueing at a carrier counter; you buy a plan in an app, tap to activate, and you're connected. It's become the default move for frequent travellers hopping between countries.
The setup here was about as smooth as it gets. The writer had already used up a plan with a different eSIM provider after arriving in Montenegro, so MobileSIM was a mid-trip test: download, buy a week-long plan, activate. The whole thing took under five minutes on an iPhone and worked without a hitch.
Three things earned the thumbs-up. Price was the big one — the reviewers called it one of the cheapest eSIM options they'd seen for Europe. Performance came next: the connection held up in both coastal towns and rural inland areas, with speeds solid enough for navigation, uploading photos and video, email, and video calls. And there were no hidden fees or confusing terms to untangle.
The obvious caveat: this was a single-country test. The reviewers haven't yet tried MobileSIM elsewhere, so there's no data on how it performs across other destinations, even though its low pricing is aimed squarely at European travel. They plan to keep testing it and report back.
A few practical tips if you're considering it. Check that your phone supports eSIM in the first place — most recent models do, but it's worth a quick look before you pay. Since eSIM performance depends on which local networks a provider taps into, results can shift from place to place. And anyone who depends on data for work should keep a second eSIM provider as a backup, just in case a plan underdelivers on the ground.
One transparency note: the review was sponsored by MobileSIM, though the authors say the opinions are their own. Even accounting for that, the takeaway is simple — if you're heading to Montenegro or elsewhere in Europe and want cheap, dependable data without the SIM-card shuffle, MobileSIM is a reasonable candidate to try, with the usual wisdom of not betting your whole trip on a first-time provider.
For travellers, the bigger point is that eSIM pricing keeps getting more competitive. Comparing a couple of providers before a Europe trip can save real money, and five minutes of setup at your hotel beats an afternoon spent finding a phone shop.
