How to Avoid Expensive Roaming Charges and Stay Connected Abroad

Arriving in a new country without mobile internet can make even simple tasks difficult. You need directions to your hotel, want to message someone that you've landed, or need to arrange a taxi. The last thing you want is to discover that using your usual mobile data will cost more than expected.

Fortunately, staying connected abroad doesn't have to involve expensive roaming charges or searching for a SIM card shop after landing. With a little preparation, you can have mobile data ready for your trip and know what you're paying before you leave.

Here's how to organise your mobile connection, choose the right amount of data and get online when you arrive.

Why mobile roaming can become expensive

When you use your regular SIM abroad, your mobile provider connects you to a network in the country you're visiting. This is called international roaming.

Some phone contracts include roaming in selected destinations. Others charge a daily fee or bill separately for mobile data. These charges can add up over a holiday, especially if you're using maps, uploading photos or browsing throughout the day.

Before travelling, check whether your destination is included in your existing mobile plan. If it isn't, compare the cost of roaming for your entire trip against a prepaid travel data package.

For example, a roaming fee of £5 per day would cost £50 over a ten-day holiday. A prepaid travel eSIM gives you another option: choose a suitable data package in advance rather than paying a daily fee to your home network.

What is a travel eSIM and why is it useful?

An eSIM is a digital SIM installed directly onto a compatible smartphone. Instead of inserting a physical SIM card, you install the mobile plan using the instructions provided after purchase.

A travel eSIM is designed to provide mobile connectivity in another country. You can purchase it online, prepare it before departure and use it when you reach your destination.

That makes it particularly convenient for travellers who want to:

Use Google Maps and navigation immediately after landing.
Message family and friends without depending on airport Wi-Fi.
Access hotel reservations, transport apps and travel bookings.
Stay connected while exploring cities and attractions.
Keep their usual SIM installed while using a separate mobile data plan.

Most travel eSIMs are data-only. That means they provide internet access for apps, browsing and messaging rather than a new telephone number for ordinary calls and SMS.

How Astaroam makes staying connected abroad easier

One way to prepare your mobile connection is through Astaroam, a travel eSIM provider offering prepaid data plans for destinations around the world.

Instead of waiting until you arrive to find a mobile shop, you can choose your destination, select a data package and receive installation instructions digitally.

Astaroam offers both fixed-data and unlimited plans, giving travellers a choice based on how they expect to use their phones.

Choose a plan that suits your trip

If you're visiting a city for a few days and mainly need navigation, messaging and browsing, a fixed-data plan can be a straightforward choice.

For longer holidays or heavier internet use, larger allowances and unlimited options provide additional flexibility. Unlimited plans have fair usage conditions, so the plan details explain how much high-speed data is included and whether speeds change after that allowance.

You can compare the available packages before purchasing, including their data allowances, validity periods and supported networks.

Get everything ready before departure

After purchasing an Astaroam eSIM, you receive the information needed to install it on your phone.

Preparing the eSIM while you're still at home means you don't need to rely on finding a SIM shop or arranging a new mobile plan when you land. Follow the installation and activation instructions for your selected package.

When you reach your destination, select the Astaroam eSIM for mobile data, enable its required roaming setting and connect to a supported local network.

Keep your existing number

On a compatible dual-SIM phone, your usual SIM can remain installed while Astaroam handles mobile data.

This means you can continue using your existing WhatsApp account and registered number for messaging over the internet. Your regular mobile line can also remain available for ordinary calls and texts, although your home provider's roaming charges still apply to those services.

Top up if you need more data

Travel plans change. You might extend your stay, use more navigation than expected or spend more time away from hotel Wi-Fi.

Eligible Astaroam fixed-data plans support online top-ups, allowing you to add more data without installing another eSIM. This is particularly useful during longer trips when your usage is difficult to predict in advance.

How much mobile data should you take abroad?

The best way to choose a data allowance is to look at what you actually use your phone for.

Light users mainly send messages, check emails, browse websites and occasionally use maps. A smaller fixed-data package can work well for this type of trip.

Regular users rely on maps throughout the day, browse social media, upload photos and use transport or booking apps. A larger data allowance gives more room for everyday activities.

Heavy users stream videos, make frequent video calls, upload large files or share mobile data with other devices. Larger packages or unlimited plans are more suitable for this type of usage.

Check your phone's recent mobile data usage before buying. This gives you a useful starting point based on your own habits rather than somebody else's estimate.

You can also save data by downloading offline maps and setting app updates and cloud photo backups to Wi-Fi only.

Turkey: arrange your mobile data before flying

Turkey is a popular destination for city breaks, beach holidays and sightseeing trips. Whether you're exploring Istanbul, visiting Antalya or travelling around Cappadocia, mobile internet is useful for navigation, translation, bookings and finding places to visit.

Turkey has also introduced restrictions affecting access to some international eSIM provider websites and services. For travellers, the practical solution is straightforward: purchase and install your travel eSIM before departure.

Set it up while connected to Wi-Fi at home, save the installation details and follow the package's activation instructions.

When you arrive, you can select your travel eSIM for mobile data and connect using its supported network. This saves you from having to arrange a new connection when you're already abroad.

Saudi Arabia: stay connected from the airport onwards

Having mobile internet ready on arrival is especially useful in Saudi Arabia, where visitors frequently need maps, transport services, hotel information and messaging.

For travellers visiting Makkah and Madinah for Umrah, a reliable data connection helps with navigating unfamiliar areas, keeping in touch with family and accessing travel arrangements throughout the journey.

Buying a local SIM at the airport is one option, particularly if you need a Saudi phone number. But if your priority is mobile internet, a travel eSIM lets you organise your data before leaving home.

Astaroam offers Saudi Arabia eSIM plans with different allowances and validity periods, allowing visitors to choose a package that matches their trip.

For someone arriving after a long flight, the benefit is simple: less time arranging mobile connectivity and more time getting to their destination.

Europe: use a regional eSIM for multi-country trips

Travelling around Europe often means crossing several borders during the same holiday. You might spend a few days in France, continue into Switzerland and then travel onwards to Italy.

Rather than buying a separate data package for every stop, a regional eSIM can cover multiple destinations under one plan.

Before purchasing, compare your itinerary with the plan's country coverage list. Choose a regional package that includes all the countries you'll visit, then use the same eSIM as you move between supported destinations.

This can be particularly convenient for road trips, rail journeys and holidays involving several European cities.

How to install and use a travel eSIM

Setting up a travel eSIM is straightforward once you know the basic steps.

Check your phone. Make sure it supports eSIM and is unlocked for use with other mobile networks.
Choose your destination and plan. Select the data allowance and validity period that suit your trip.
Install the eSIM. Follow the instructions supplied after purchase, preferably while connected to reliable Wi-Fi before departure.
When you arrive, select the travel eSIM for mobile data. This tells your phone which connection to use for internet access.
Enable data roaming on the travel eSIM. Travel eSIMs commonly use agreements with local networks, so this setting is often necessary.
Disable data roaming on your regular SIM. This helps prevent your home network from using chargeable mobile data abroad.
Test your connection. Open a website or navigation app to confirm that mobile internet is working.

On phones with automatic mobile data switching, turn that feature off if you want to ensure your regular SIM doesn't take over the data connection.

What to do if your travel eSIM isn't connecting

If your eSIM has been installed but mobile internet isn't working, there are a few settings worth checking before contacting support.

Confirm that the travel eSIM is switched on and selected for mobile data.
Make sure data roaming is enabled on the travel eSIM if required by the provider.
Check the APN settings against the installation instructions.
Check the supported local network and try selecting it manually if automatic selection isn't connecting correctly.
Switch airplane mode on and off, then allow the phone a few minutes to reconnect.

If the problem continues, contact your eSIM provider with your phone model, current location and screenshots of the relevant mobile network settings.

Avoid deleting the eSIM during troubleshooting unless support specifically instructs you to do so.

Travel eSIM questions answered

Can I install my eSIM before travelling?

Yes. Preparing an eSIM before departure is often the most convenient approach. Follow your plan's instructions to confirm when its validity starts and when it should be installed.

Will I lose my existing phone number?

No. Installing a travel eSIM doesn't replace your existing SIM. On compatible dual-SIM devices, you can keep your regular number while using the travel eSIM for mobile data.

Can I use WhatsApp with a data-only eSIM?

Yes. WhatsApp messaging works over mobile internet, and you can continue using your existing account. Voice and video calling features are subject to local service restrictions.

Can I add more data during my holiday?

Yes, if your package supports top-ups. Astaroam provides online top-ups for eligible fixed-data plans, so you can add data when needed.

Is an eSIM better than buying a SIM at the airport?

A travel eSIM is particularly convenient when you want mobile data ready on arrival. A local SIM is worth considering if you need a local telephone number or plan to stay for an extended period.

Before you leave: your mobile data checklist

Check whether your current mobile plan includes roaming at your destination.
Confirm your phone supports eSIM and is unlocked.
Choose a data allowance that matches your usage and trip length.
Install your travel eSIM according to its instructions.
Save important tickets, maps and accommodation details offline.
On arrival, select the travel eSIM for mobile data and enable its required settings.
Check your regular SIM's roaming settings to avoid unwanted charges.

Stay connected without the roaming headache

Mobile internet has become an essential part of travelling. From navigating a new city to arranging transport and staying in touch with family, having a working connection makes the journey easier.

The simplest approach is to plan ahead. Check what your existing mobile provider offers, decide how much data you'll need and arrange a suitable connection before departure.

For travellers who want prepaid mobile data without visiting a SIM shop after landing, Astaroam provides a convenient way to choose and prepare an eSIM for their destination.

That means one less thing to organise when you arrive, and more time to enjoy the trip.
