Is your phone eSIM compatible?

Most newer phones already support eSIMs, and can install them in 90 seconds.

Compatible devices: If your phone was made in 2019 or later, there’s a good chance it already supports eSIM. The only usual exceptions are budget models and some phones bought in certain parts of Asia, so most travellers can skip checking entirely.

Locked phones: Most phones these days are unlocked, which means they can hop onto a new network without any fuss. The main exception can be a phone you’re still paying off on a plan, but carriers will often unlock your phone if you explain it’s for travel use.

Using two SIMs at once: If you have a dual-SIM phone, you can use a travel eSIM for internet abroad, while still using your regular SIM for calls and texts on your regular phone number. No SIM swapping, and no missed messages from home.

U.K. and Ireland eSIM

Use a U.K. and Ireland eSIM to stay connected

Traveling across British Isles? An aloSIM British Isles eSIM keeps you connected the moment you arrive, without hunting for a local SIM in each country. One plan covers the United Kingdom and Ireland, so you stay online for maps, translation, bookings and staying in touch. Every plan includes a free Hushed phone number and 90-second setup, you can top up any time in the app, and the eSIM is yours to keep and reuse on future trips — the simplest way to stay connected across British Isles without roaming bills.

UK eSIM

How much travel data do I need in the U.K. and Ireland?

How much data you’ll need in the UK and Ireland depends on your travel plans. Having access to data is a must if you’re planning to enjoy day trips, local attractions and walking tours. You can’t always rely on Wi-Fi!

What makes a UK and Ireland eSIM so great is that you can buy data in smaller packages and top up as you go!

U.K. and Ireland eSIM

Should I buy individual eSIMs for the United Kingdom and Ireland, or a combined U.K. and Ireland eSIM?

That’s totally up to you! We offer identical pricing for our United Kingdom eSIM data packages, our Ireland eSIM data packages, and our combined U.K. and Ireland eSIM data packages.

But if you’ll be spending time in both the U.K. and Ireland, it makes sense to stick with one eSIM that works in both countries. Then you don’t have to worry about having leftover data for one country that can’t work in the other country.

Questions?

Yes. Your aloSIM British Isles eSIM connects automatically to trusted local networks across the United Kingdom and Ireland, so a single plan keeps you online as you travel between countries. Most phones bought after 2020 support eSIM if they are carrier-unlocked, so you can activate before you leave and connect the moment you arrive.

aloSIM is a strong choice for British Isles because one plan covers the United Kingdom and Ireland without swapping SIMs at each border. Plans are priced for travelers, every plan includes a free Hushed phone number for calls and texts, and setup takes about 90 seconds. That mix of wide coverage and a built-in number is rare among competitors.

Buy your British Isles plan in the aloSIM app before you travel, open ‘My eSIMs’, and tap ‘Install eSIM’. Installation takes about 90 seconds. Toggle the eSIM on and allow roaming when you arrive, and your device connects automatically to a local network — no physical SIM and no airport kiosk required.

Yes. aloSIM works alongside your home SIM on dual-SIM phones, so you keep your usual number active for calls and texts while your British Isles eSIM handles data. Check your home provider’s roaming charges first so you know what they bill for any use of your primary line abroad, then route your data through aloSIM to save.

For maps, messaging and everyday browsing, 1–3 GB per week suits most travelers. If you stream video, share your connection or work on the road, choose a higher-GB plan or an unlimited option. aloSIM lets you top up any time in the app, so you can start small and add more if you run low.

For most travelers, yes. Carrier roaming often runs $10–15 per day whether or not you use much data. Your aloSIM British Isles plans cost a fraction of that, and you pay only for the data you need, which over a week-long trip usually adds up to a real saving versus a standard roaming add-on.

Yes. Every aloSIM plan includes a free Hushed phone number for calls, texts and app verification — handy for hotel check-ins, WhatsApp and local sign-ups as you move between countries. Many data-only eSIMs leave this out or charge extra, so it is a real advantage when you are traveling across British Isles and want one reliable number the whole way.
