Does O2 Work in Other Countries?

O2 is the second-biggest network in the UK, with leading coverage and over 23.2 million subscribers across the country. But, most importantly for those eager to see the rest of the world, it’s often considered the best network for travellers, too, with a number of benefits that make it particularly attractive for those that roam when stacked up against its competitors.

Chief among these benefits is O2’s incredible roaming package, which allows any customers with an allowance of up to 25GB to use the same amount of data anywhere in its Europe Zone (more on that later). This comes standard with any plan, including both pay monthly contracts and pay-as-you-go plans. The benefits of this really can’t be overstated. 25GB is far more data than most subscribers will use up in a typical vacation, and if you end up needing more, it’s easy to add more data or simply switch to a local network of your destination. In our opinion, this is best combined with one of O2’s pay-as-you-go plans, which give you full control without locking you into long contracts. You only pay for what you actually use, with no nasty surprises on your bill. If you run out of that 25GB roaming data allowance or simply find a better option, you can swap out the SIM and switch to network local to where you’re travelling without any hassle at all. Of course, if you do go with pay-as-you-go, you need to ensure your data stays topped up. The best place to do this is mobiletopup.co.uk, which gives you access to instant delivery of O2 top up vouchers to your inbox no matter where you are in the world. Here, we’ll dive into the benefits O2 provides to travellers, and give you a guide to topping up abroad.

How does O2’s 25GB data roaming allowance work?

Whether you’re using a pay-as-you-go plan or a pay monthly plan outside of the UK, you can use your normal data allowances—up to 25GB per 30-day period, at least—anywhere in the company’s Europe zone. Note that for PAYG, this only applies if you purchase a “Big Bundle” or “Rolling” plan. Once that 25GB runs out, though, it’s important to know that pay-as-you-go customers will need to purchase a Data Roaming Bolt On, which are quite expensive. For pay monthly customers, the 25GB allowance resets with your normal billing cycle. Which countries are included in the Europe zone? O2’s Europe zone includes Austria, Azores, Belgium, Bulgaria, Canary Islands, Croatia, Cyprus*, Czech Republic, Denmark, Estonia, Finland, France, French Guiana, Germany, Gibraltar, Greece, Guadeloupe, Hungary, Iceland, Ireland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Madeira, Malta, Martinique, Mayotte, Netherlands, Norway, Poland, Portugal, Reunion, Romania, Saint Barthelemy, Saint Martin, San Marino, Slovakia, Slovenia, Spain, Sweden, United Kingdom, and Vatican City. What European destinations it DOESN’T include are Guernsey, Isle of Man, Jersey, Monaco or Switzerland. For these, you need to purchase an O2 Travel Bolt On, which is basically a small extra package that is free to sign up for.

What about outside of the Europe zone?

If you’re heading outside of Europe, you can purchase the O2 Travel Bolt On for £7 in a wide variety of locations, including the following:
