Why Choose O2 for Data and Calls?

O2 is one of the biggest networks in the UK, and it’s not just about fast data. They are also popular because of their international minutes and affordable roaming across Europe. For students, travellers, or even people living in the UK who call abroad often, O2 international calls can save a lot of money.

Imagine calling your family back home while studying in London or working in Berlin. Instead of paying crazy roaming fees, O2 lets you use your plan in many EU countries without extra charges. That’s where O2 Europe calls come into the picture; they are included in most plans, and you don’t need to think twice before dialling.

And if O2 is not available where you are? Don’t worry. You can also connect using a UK eSIM on EE Network or even Vodafone (VDF). All three networks are strong across the UK and Europe.

The Power of eSIM on O2, EE, and Vodafone

No more waiting for a SIM card in the post. With an eSIM, you just scan a QR code and you’re ready to go. This is especially handy if you travel a lot between the UK and the EU.

Here’s what you get with eSIM plans on O2, UK eSIM on EE Network, and VDF:

• Instant setup: No stores, no delays, no tiny SIM trays.
  
• Strong Network coverage: Offer 4G and 5G network across the UK and most of Europe as well.
  
• Affordable Packages: Understand your needs, and you can select your plan from multiple options.
  
• Flexible use: Keep your existing number, or get a new local UK number if you want.
  

So when people ask why go for an O2 data plan on eSIM, the answer is simple: it’s quick, reliable, and cheaper than roaming.
