How to avoid mobile roaming fees on your summer holiday

Your summer holiday should be a time for enjoyment and relaxation, rather than worrying about incurring mobile roaming fees. But every year, businesses and individuals alike get caught out by unexpected phone charges, sometimes with shocking results.

At DB Communication, we recently spoke to a customer who was billed more than £2,000 for using less than 1MB of data while at sea. It’s a perfect example of how quickly costs can spiral when you’re not fully aware of how mobile roaming fees work.

The good news is that with a bit of awareness and planning, these situations are completely avoidable. Read on to learn more…

What are mobile roaming fees?

When you leave the UK, your phone will automatically connect to partner networks in that country, and the costs can vary massively depending on your location and provider. While many people are familiar with EU roaming rules, things become far less predictable once you move beyond standard coverage areas.

One of the most common mistakes is when people assume they’re still covered by a UK network, when in reality they’ve connected to a completely different (and much more expensive) provider.

The hidden risk of using your phone at sea

Using your phone on a ferry, cruise ship, or any boat is one of the easiest ways to run up huge charges. Out at sea, your phone often connects to a satellite network rather than a standard mobile provider. These satellite networks are not covered by typical roaming agreements, meaning the costs per MB can be extremely high.

This is precisely how our customer ended up with a £2,000 bill for barely any usage.

The safest approach is simple. When you’re afloat, it’s best to switch off data roaming entirely. Even background activity like emails refreshing or updating apps can trigger charges.

Why flight mode matters

Most people switch their phone to flight mode during a journey, but it’s worth understanding why it matters. When you’re on a plane, especially one that offers onboard connectivity, your phone may attempt to connect to satellite-based services. Just like at sea, these connections can lead to expensive mobile roaming fees.

Keeping your phone in flight mode ensures it doesn’t connect to a network automatically, unless you deliberately turn the wi-fi on. It’s a simple step, but one that can prevent unnecessary charges.

Don’t assume your mobile plan covers everything

Not all roaming is created equal. What’s included in your plan might only apply to certain countries or regions, and charges can change depending on where you are. Before you travel, it’s always worth checking exactly what your provider includes. A quick conversation can clarify whether you’re covered, what your limits are, and what charges apply if you go over.

It’s far better to know in advance than to find out when the bill arrives.

Monitor background data usage

One of the biggest causes of unexpected mobile roaming fees is data being used without you actively doing anything. Apps updating, emails syncing and cloud services running in the background can all quietly use precious data.

When you’re abroad, that background activity can become surprisingly expensive, so take a moment to adjust your settings or limit usage.

Try a smarter alternative: eSIMs

When you travel, eSIMs are becoming the easiest and most cost-effective way to stay connected. DB Communication offers eSIM solutions that are quick to set up and simple to use. Instead of relying on standard roaming, you can connect to local networks with clear, controlled pricing.

This gives you far more certainty over what you’re spending, without the risk of unexpected charges building up in the background.

Stay connected without the stress

At DB Communication, we help businesses and individuals find smarter ways to stay connected, whether that’s through better mobile plans or easy-to-use eSIM solutions.

If you’re planning to travel this summer and want to avoid unexpected costs, it’s worth having a quick conversation before you go. It could save you far more than you expect.
