Stepping off the plane in Bangkok, the humid air hits you before your feet hit the tarmac. It is a familiar sensation, almost comforting in its consistency. What follows, for many of us, is a cheerful text from our UK network, welcoming us to Thailand and helpfully informing us of today’s roaming charge.
It is, to put it mildly, a mood killer. The good news is that staying connected abroad in 2026 has never been more straightforward, or more affordable, provided you know your options.
This is not a conversation about cutting corners. It is about being a smarter traveller, which, after fifty-plus years on this planet, is something we are rather good at.
The Roaming Problem Has Got Worse, Not Better
Since Brexit, the landscape of mobile roaming has shifted considerably for UK travellers. The old “Roam Like at Home” arrangement, which allowed us to use our domestic allowances across Europe at no extra cost, is largely gone.
UK providers have steadily reintroduced daily fees for European travel, typically ranging from £2 to £3 per day with the major networks.
That might sound manageable. However, a two-week trip to Spain or Portugal can quietly add £28 to £42 to your bill before you have ordered your first glass of wine. For those of us heading further afield, to Southeast Asia, India, or the Americas, the charges are considerably steeper.
The fundamental issue is this: when you roam, your home network borrows infrastructure from a foreign carrier and passes the cost directly to you, often with a healthy margin added for good measure.
It is a system designed for occasional, short-term use. It was never intended to be a long-term connectivity strategy.
What Is an eSIM, and Why Should You Care?
The most significant development in travel connectivity over the past few years is the eSIM. It stands for embedded SIM, and it is, in essence, a digital SIM card built directly into your phone during manufacture.
Rather than hunting for a SIM card kiosk in a foreign arrivals hall, or fiddling with a tiny ejector tool over a toilet, you purchase a data plan through an app before you leave home. When you land, you activate it. Within minutes, you have local data at local prices.
I have been using Airalo for this, and it has become as much a part of my pre-departure routine as checking my passport. The interface is clean and logical.
You select your destination, choose a data package, and follow the installation steps. For Thailand, a 5GB plan covering 30 days costs £6.50. For a regional Southeast Asia plan covering multiple countries, you are looking at comparable rates.
The key requirement is that your phone must be eSIM-compatible and unlocked. Most smartphones manufactured after 2018 support eSIM, including iPhones from the XR onwards and a wide range of Android devices. If you are unsure, a quick search of your model number will confirm it.
The Local SIM Card: Still a Solid Option
The eSIM is not the only solution, and for longer stays or those who prefer a more hands-on approach, the local SIM card remains a perfectly respectable choice. In most Southeast Asian countries, buying a tourist SIM at the airport is straightforward and remarkably affordable.
In Thailand, for instance, you can pick up a 30-day tourist SIM with a 30GB data allowances for roughly 900-1000 baht (£20-£25). Vietnam, Bali, and Cambodia are similarly well-served.
The process involves presenting your passport, selecting a package, and waiting a few minutes while the card is activated. The trade-off is that you will temporarily lose access to your UK number.
This matters primarily for two-factor authentication texts from your bank. My workaround is simple: I notify my bank before I travel, complete any sensitive transactions before I leave, and use my eSIM or hotel Wi-Fi for anything requiring a UK verification code.
If you are planning to use local transport apps or booking services, a local number can also be useful. My post on How to Navigate Bangkok Solo Over 50 Using Public Transport covers this in more detail, including which apps require local registration and which do not.
The Offline Toolkit: Your Best Free Resource
Before reaching for a data plan, it is worth considering how much connectivity you actually need. A surprising amount of travel can be done entirely offline, with a little preparation.
Google Maps allows you to download entire regions for offline use before you leave home. Once downloaded, the GPS navigation functions without any data connection whatsoever.
I download the maps for every city I plan to visit before I board the plane. It has saved me more than once in places where data coverage is patchy.
Beyond maps, most streaming services, including Spotify and Netflix, allow offline downloads. Guidebook apps such as Lonely Planet and iOverlander have offline modes.
Even translation apps like Google Translate allow you to download language packs for offline use, which is invaluable in rural Southeast Asia.
The goal is not to disconnect entirely. It is to be deliberate about when you need data and when you do not. This mindset, combined with a modest eSIM plan, means you can travel comfortably without burning through data or budget.
Staying in Touch: Free Calls and Messages Abroad
The question of how to call home without incurring international call charges has a simple answer: use Wi-Fi. WhatsApp, FaceTime, and similar applications allow for free voice and video calls over any Wi-Fi connection.
This means your hotel, a cafe, or your eSIM data plan can all serve as the conduit for keeping in touch. WhatsApp, in particular, has become the default communication tool for travellers of all ages.
It is how I coordinate with Peter when we are in different countries, and how I reassure people back in blighty that I have not, in fact, been eaten by anything. It works on both iOS and Android, requires no special setup, and uses minimal data.
For those who are less familiar with these tools, my post on walks through the setup process in plain language, without assuming any particular level of technical confidence.
One additional note on security: public Wi-Fi networks, particularly in hotels and airports, are not always secure. If you are accessing banking apps or sensitive accounts, consider using a VPN.
It encrypts your connection and provides a meaningful layer of protection. There are several reputable options available for a few pounds per month. Personally, I use McAfee bank grade encyption VPN which comes included with my antivirus subscription.
A Quick Comparison: Your Options at a Glance
| Option | Cost | Best For | Drawbacks |
|---|---|---|---|
| Home Network Roaming | £2–£6/day (Europe); higher elsewhere | Very short trips only | Expensive; charges can accumulate quickly |
| eSIM (e.g., Airalo) | From ~£3.50 per plan | Most travellers; multi-country trips | Requires eSIM-compatible, unlocked phone |
| Local SIM Card | From ~£3–£25 | Extended stays; single country | Lose UK number; requires unlocked phone |
| Wi-Fi Only | Free | Budget travellers; light data users | Unreliable; security risks on public networks |
Before You Leave: A Practical Checklist
A little preparation before departure removes almost all of the friction from staying connected abroad. The single most common mistake I see, and have made myself, is leaving these decisions until you are standing in an arrivals hall at midnight, jet-lagged and surrounded by competing SIM card vendors.
Check that your phone is unlocked. If you are on a contract, contact your provider and ask them to unlock it before you travel. This is a legal requirement in the UK, and most providers will do it free of charge. Once unlocked, your phone can accept any SIM or eSIM, giving you full flexibility.
If you enjoy travelling with the best travel gadgets for over 50s, you will already appreciate the value of being prepared. Connectivity is simply another item on that list.
Final Thoughts
Roaming charges are, at their core, a tax on the unprepared. With a modest amount of planning, they are entirely avoidable. The eSIM has made this easier than ever, and for those who prefer a physical option, local SIM cards remain a reliable and affordable alternative.
The technology has caught up with the way we travel. The only thing left is to catch up with the technology. If you are still navigating the broader world of travel tech, visit my page introducing this new AI Travel Planner ideal for Solo Travellers Over 50. It can genuinely simplify the planning process from start to finish.
Travel well, travel smart, and for goodness’ sake, turn off your roaming before you board.
A note on how I write: Every trip starts with a journal, filled in wherever I happen to be; on a bus, plane, train, or in a backstreet cafe that has clearly seen better days. It’s not tidy, and it’s not always legible even to me. When I get the time, I use AI to help turn those notes into something readable, organising drafts and occasionally rescuing a sentence that has wandered off without me. The experiences, the perspective, the humour and every editorial decision remain entirely mine. As for the photos, I’m not remotely fond of having my picture taken, family portraits included, so I also use AI to help visualise the places and moments I write about.
