London, Manchester, and the Dover coast have attracted Israeli tourists for years. But while trip plans are meticulously organized, browsing abroad is often forgotten — until the bill arrives. Here are five recurring mistakes and how to avoid them.
1. Relying on roaming without checking costs in advance
The biggest mistake: arriving in Britain and assuming your Israeli SIM will simply "work." International roaming can be a nightmare. Israeli cellular companies will send you SMS messages with rates, but while you're traveling, you're already committing to high costs. Checking your operator's roaming rates in advance is a must, but even that doesn't guarantee costs won't spiral.
2. Forgetting to disable data roaming on your Israeli SIM
Here's the mistake that turns your phone into a problem: your Israeli SIM stays in the device, and data roaming on it is enabled by default. As a result, every email check, every app update, even silent notifications use roaming and rack up a huge bill. Recommendation: Upon arrival at your destination, immediately disable data roaming on your Israeli SIM in your phone settings.
3. Not enabling airplane mode during the flight
The third mistake is technical but costly: your phone tries to connect to cellular networks during the flight, and when you land in Britain, it immediately connects to roaming. Just a few minutes of unaware data usage can lead to significant charges. Airplane mode is a simple yet effective safeguard.
4. eSIM — incorrect installation or compatibility issues
More and more travelers are choosing eSIM as a smart solution. nRed's eSIM enables instant installation by scanning a QR code — no physical card needed, no need to swap your SIM. But a common mistake is failing to check phone compatibility in advance. Not every phone supports eSIM, and some require specific feature activation. Check your device before your flight to avoid surprises at the airport.
5. Not keeping a backup of connection details
Whether you're using an eSIM or a local SIM card, a common error is not saving your connection information (activation checks, QR codes, usernames). If your device encounters a problem, it will be very difficult to resolve it abroad without this information. Save a screenshot of every connection detail in your email or cloud storage.
The simple solution
eSIM offers a way to avoid many of these mistakes. Without needing a physical card and without relying on complicated swaps, you control your connection from the moment you arrive. Installation by scanning a QR code takes minutes, and your data starts flowing immediately. Your Israeli SIM stays in your device, and all you need to do is disable roaming — so you're in complete control of costs.
Britain awaits. And all it takes is a little planning ahead to make your trip connected, affordable, and hassle-free.
