Can I use my unlimited data abroad?

Man using phone at the beach

I’m going on holiday next month, and want to be sure I can use my unlimited data abroad? And if so, how much will it cost?

Thanks for your question, Kev…

Planning a holiday can be hectic enough, even without any extra worry about incurring extra charges when you use the internet on your phone overseas.

Good news is, you absolutely can use your unlimited data plan abroad. But unlike in the UK where unlimited data plans allow you to use as much data as you like (within reason), there may be much tighter restrictions on how much data you’re permitted to use when you’re overseas. This depends on your network’s policy.

Here’s everything you need to know, including which networks will and won’t restrict your roaming data use, as well as the best plans for unlimited data and how much you can expect to pay.

What is unlimited data?

As its name suggests, an unlimited data plans lets you use as much as you want without incurring charges. But as we’ll see while you’re overseas, ‘unlimited’ doesn’t necessarily really mean unlimited.

If you want peace of mind while you’re travelling, opting for unlimited data is a good idea. Especially if you’re an avid gamer, or you plan to watch a lot of TV shows and movies on your phone while you’re travelling.

Alternatively, if your network of choice doesn’t offer any unlimited data plans, you’ll probably find that it offers a generous data allowance, albeit one that’s not totally unlimited.

For using data abroad, most networks have deals and bolt-ons that make it easy to get what you need.

Which phone networks offer unlimited data plans abroad?

You’ll find unlimited data plans from a number of networks, including: Vodafone, Three, EE, iD Mobile, Virgin Mobile, VOXI, Smarty, iD Mobile and giffgaff.

Each network has a different approach to offering data when you go on holiday. Some will offer bolt-ons and deals, while others will let you use your current package.

To that end, it pays to check with your network provider to see what bolt-ons and deals are available. Here’s what the big four networks – Three, O2, Vodafone and EE – have to offer:
