O2 travel eSIM: How to use O2 outside the UK
Learn how to get data outside of the UK with an O2 travel eSIM. Our guide outlines coverage, price, data plans, minutes of calls included, and ease of use.
If you’re an O2 customer planning on using an eSIM for your next international trip, then an O2 travel eSIM might be a great choice.
In this guide, we help you decide whether an O2 travel eSIM is right for you by looking into plans and pricing, coverage, and ease of use. We also present Holafly as an unlimited data eSIM alternative if you need more data and wider coverage.
Peace of mind before you fly
Set up your eSIM before travel and get unlimited data on arrival.
Does O2 sell travel eSIMs for outside the UK?
Although O2 doesn’t sell travel eSIMs directly, you can get an eSIM for Europe from third-party websites, such as eSIM.net.
If you want to stick with O2 for other international destinations, you’ll need to rely on O2’s international data roaming through your existing plan, which may include travel passes, roaming add-ons, or pay-as-you-go rates depending on your location.
O2’s pay-as-you-go bundles and rolling plans offer up to 25 GB of data for use across Europe. However, they’re only available as physical SIMs. So while there are O2 tourist SIM cards available, there are no eSIM options currently on offer.
O2 travel eSIM plans and pricing
O2 travel eSIM plans all include data, minutes of international calls within the UK and Europe, and incoming SMS that last for 30 days from purchase. You get a +44 O2 UK mobile number with your plan, as well as unlimited inbound calls and texts in the UK and Europe.
There are two plans to choose from: O2 travel eSIM and O2 travel Plus eSIM. Info for each is as follows:
| Plan | O2 travel eSIM | O2 travel Plus eSIM |
|---|---|---|
| Data allowance | 20 GB total (usable while roaming) | 50 GB (35 GB usable while roaming) |
| Minutes of calls within the UK and Europe | 500 | 500 |
| No. of countries covered | 48 | 48 |
| Mobile hotspot | ✅ | ✅ |
| 5G whenever available | ✅ | ✅ |
| Validity period | 30 days | 30 days |
| Price | $20 USD | $23 |
These plans support mobile hotspot and tethering at no extra cost, as well as 5G, whenever available. If you subscribe for three or six months, you can get a discount of up to 15%.

O2 travel eSIM coverage
All O2 travel eSIM plans include data coverage and roaming in the countries below:
| Austria, Azores, Belgium, Bulgaria, Canary Islands, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, French Guiana, Germany, Gibraltar, Greece, Guadeloupe, Guernsey, Hungary, Iceland, Ireland, Isle of Man, Italy, Jersey, Latvia, Liechtenstein, Lithuania, Luxembourg, Madeira, Malta, Martinique, Mayotte, Monaco, Netherlands, Norway, Poland, Portugal, Reunion, Romania, Saint Martin, San Marino, Slovakia, Slovenia, Spain, Sweden, Switzerland, Vatican City, and United Kingdom |
Keep in mind that using your O2 international SIM outside these locations will consume your remaining allowance and may cause your eSIM to stop working.
How to install and activate O2 travel eSIM
Before reading on, please note that your plan’s validity period of 30 days starts as soon as it is purchased, so make sure to buy your O2 travel eSIM plan only when you’re ready to use it.
With that in mind, follow these steps to set up your eSIM:
- Purchase your O2 international SIM plan.
- Check the QR code sent to your email.
- Scan the QR code with your device. Make sure your phone is eSIM compatible.
- Complete the installation by following the instructions on your phone.
Some steps may differ depending on whether you’re using an iPhone or an Android phone.
Travel abroad using O2 international roaming
Depending on your needs, you can explore O2’s international roaming options instead. Whether you’re using O2 roaming in Europe, O2 roaming in the USA, or travelling from the UK to another international destination, O2 lets you stay connected with their travel-inclusive, travel pass, and pay-as-you-go plans like the O2 tourist SIM.
However, roaming charges can add up quickly without you noticing. To give you an idea, pay-as-you-go roaming plans can cost as much as £7.20 per MB, depending on the country/region. It may be a good idea to explore unlimited data options, such as Holafly, if you expect high data usage.
