Frequently Asked Questions

  • What is a travel eSIM?

    A travel eSIM is a digital SIM profile that lets a compatible device use a mobile plan without inserting another physical SIM. Choose a plan with coverage, data allowance and validity that match your trip.

  • Is an eSIM cheaper than using my home network abroad?

    It depends on your existing tariff. Compare the eSIM price with any included roaming allowance, daily charges and fair-use limits on your home plan. Check both options for your destination and travel dates.

  • How do I install a travel eSIM?

    Connect to reliable Wi-Fi or another internet connection and follow the QR-code or installation-link instructions supplied with your plan. Select the travel eSIM for mobile data and apply the roaming settings in those instructions.

  • Which phones support eSIM?

    Support depends on the exact phone model, regional variant and carrier restrictions. Check our device compatibility page and make sure the phone is unlocked before purchasing.

  • Can I keep my usual phone number?

    On a compatible dual-SIM device, you can retain your home line while selecting the travel eSIM for data. Calls, texts and voicemail on the home line may still incur roaming charges. Disable home-line data roaming and automatic data switching.

  • When does an eSIM plan start?

    Check the activation policy of the plan you choose. Installation, activation and first connection to a supported network can be different events. Follow the supplied instructions so you do not start the validity period earlier than intended.

  • Does an unlimited eSIM have any limits?

    Unlimited plans may have fair-use policies, speed reductions or hotspot conditions. Read the specific plan details before buying and check whether the terms suit your expected use.

  • Can I share eSIM data with a laptop or tablet?

    If your device and selected plan support hotspot or tethering, you can share the mobile connection. Connected devices use the plan data allowance and may be subject to hotspot or fair-use limits.

  • Will a regional or global eSIM work everywhere?

    No. Coverage is defined by the country list on each plan. Check every stop on your route, including transit destinations where you need mobile data.

  • What should I do if my eSIM has no data?

    Check that you are in a covered destination, the plan is valid, data remains available and the eSIM is selected for mobile data. Follow the supplied roaming and network instructions. Contact support before deleting the eSIM profile.

  • Why choose SimplySIM over Airalo or Holafly?

    SimplySIM is a UK-registered company that prices every plan in pounds, so UK cards pay no foreign-transaction fee. It sells both capped plans and unlimited plans, allows hotspot and tethering, and offers UK-based support, a student discount and a price match guarantee. See the full comparison on our SimplySIM vs Holafly vs Airalo page.

  • Can I use my SimplySIM eSIM as a hotspot?

    Yes. Hotspot and tethering are supported, so you can share your mobile data with a laptop, tablet or travelling companions. Shared devices use your plan allowance, so choose a larger or unlimited plan if several people will connect.

  • Do you sell unlimited data eSIMs?

    Yes. SimplySIM offers capped plans from 1GB up to 50GB and unlimited plans for most destinations. Each plan page states its allowance, validity, covered countries and any fair-use terms.

Why Choose SimplySIM Over Other eSIM Providers?

SimplySIM is a UK-based travel eSIM provider covering 180+ destinations. Unlike most eSIM providers, we price everything in pounds, offer both capped and unlimited data plans, and include a free VPN with plans of 5GB or more.

Priced in GBP, no hidden fees

SimplySIM charges in pounds sterling. Most international eSIM providers bill in US dollars or euros, so UK customers pay an extra 2–3% in card currency-conversion fees on every purchase. With SimplySIM the price you see is the price you pay.

Capped and unlimited plans

Most providers only sell one plan type - cheap capped allowances or premium unlimited data. SimplySIM sells both, from 1GB starter plans to unlimited data, so light users and heavy streamers both get the right plan without switching provider.

Free VPN included

Every SimplySIM plan of 5GB or more includes a free VPN gift, protecting you on hotel and airport Wi-Fi. No other major travel eSIM provider bundles a VPN at no extra cost.

Full hotspot & tethering

SimplySIM eSIMs allow hotspot and tethering on your full allowance, so one plan can connect your laptop or the whole family. Some competitors restrict tethering to as little as 500MB per day, even on "unlimited" plans.

UK-based company & support

SimplySIM is a UK company with support in UK hours from a team that knows UK networks, banks and devices. If something goes wrong mid-trip, you get real help fast - not a chatbot in another timezone.

Rewards & discounts

Verified students get a dedicated student discount, and anyone can earn 5% back in tokens through the SimplySIM affiliate programme - tokens you can spend on your own future eSIMs. Plus a free Holiday Trip Planner app for iOS and Android.

Comparing SimplySIM with Airalo or Holafly? Airalo focuses on capped plans, Holafly on unlimited - SimplySIM offers both, usually for less, in pounds. See the full side-by-side feature and price breakdown:

Why Choose a Travel eSIM for Your Next Trip Abroad?

A travel eSIM is a digital SIM you download to your phone before you fly. It gives you mobile data abroad without a plastic SIM card, a hunt for a phone shop on arrival or a surprise roaming bill. SimplySIM sells data only eSIMs for 180+ countries, priced in pounds and set up from the UK in a few minutes.

Connected the moment you land

Install your eSIM for travel at home over Wi-Fi, then switch it on when you arrive. Your UK SIM stays in your phone for calls and texts while the eSIM handles your data, so there's no swapping cards at the airport. Before you buy, check your model on our eSIM compatible phones list.

Travel eSIM vs roaming: what you really pay

Most UK networks charge a daily fee to use your phone abroad, and outside Europe that can add up fast over a week or two. A travel eSIM is a one-off price for a set amount of data, with nothing added to your monthly bill. Use our data cost comparison to see the difference for your trip.

One international eSIM for Europe and beyond

Choose a single country plan for France, Italy or Japan, or pick a regional or global eSIM if you're crossing borders. A travel eSIM for Europe covers several countries on one plan, so you won't need a new SIM card at every stop.

How to choose the best travel eSIM

Look past the headline price. Check which local networks a plan uses and how much data you really get, as some "unlimited" plans slow right down or cap hotspot use after a small daily amount. SimplySIM offers capped plans from 1GB to 50GB and unlimited plans for most destinations, with hotspot allowed on your full allowance. Check signal where you're going with our network coverage checker.

Unlimited data eSIM for heavy users

Streaming, video calls and maps on the go can burn through data quickly. An unlimited data eSIM removes the worry of running out mid-trip, and you can still pick a capped plan if you only need data for messages and directions. See what's available for Thailand or the United States.

Travel eSIM or travel SIM card?

A physical travel SIM card has to be posted to you or bought on arrival, and you have to take out your UK SIM to use it. A travel eSIM arrives by email, sits alongside your UK SIM and can be topped up if you need more data. It's the easier option for trips to places like Morocco.

Popular holiday eSIMs from the UK

Some of our most popular plans are for sunny breaks from UK airports, including Turkey, Egypt, Spain and Portugal. Buy before you fly and you'll have data for taxis, maps and messages as soon as you step off the plane.

How much data do you need abroad?

Maps and messaging use very little data, while video calls and streaming use a lot more. A week of light use often fits in a few gigabytes, but heavy users should look at bigger or unlimited plans. Our travel data calculator estimates what you need from how you use your phone.

Keep WhatsApp and your UK number

A data only eSIM doesn't give you a new phone number. WhatsApp, iMessage and FaceTime keep working with your usual number over the eSIM's data, and your UK SIM can stay on for texts such as bank security codes. Just turn off data roaming on your UK line so you aren't charged.

Share your data with hotspot

Every SimplySIM eSIM lets you use your phone as a hotspot, so a laptop, tablet or travel companion can get online from the same plan. It's handy for working away or keeping the kids' tablets connected on a long journey. Shared devices use your plan's data, so choose a bigger plan if several people will connect.
