giffgaff includes EU roaming on its plans, but its allowance works differently from most networks: the cap is counted per plan rather than per month, which catches some travellers out. This guide explains exactly what you get, what happens when you run out, and how giffgaff compares to the other budget networks you might pick instead.

How we put this guide together
To put this guide together, we reviewed giffgaff's published roaming terms against giffgaff's own help pages, checking the included allowance, the fair usage caps, the out-of-bundle charges, the travel data add-on pricing structure, and the list of covered destinations. giffgaff runs on the O2 network, and coverage reliability assessments reference the most recent RootMetrics UK RootScore Report and Ofcom Connected Nations data.
Does giffgaff include roaming?
Yes. All giffgaff plans, which giffgaff calls goodybags, include EU roaming at no extra cost under a Roam Like at Home arrangement. You can use your plan's data, minutes, and texts across the EU and a list of selected destinations just as you would in the UK, with no daily charge to unlock your allowance. This applies to plan customers. If you use giffgaff on a pay as you go basis without a plan, you pay standard roaming rates from your credit instead.
There is one condition worth knowing up front. New members may not get inclusive roaming straight away if they have not yet used giffgaff in the UK, in which case roaming has to be enabled before it works abroad. We cover that in the fair usage section below.
Where can you roam with giffgaff?
giffgaff's inclusive EU roaming covers 37 destinations, which it groups together as the EU zone: the 27 EU member states plus 10 additional locations including Iceland, Norway, Liechtenstein, Gibraltar, and several French overseas territories such as Martinique and Reunion.
Two omissions catch people out. Switzerland is not in the inclusive EU zone, despite sitting in the middle of Europe, and neither is Turkey. Both are instead available only through paid travel data add-ons. If your trip includes a Swiss leg, do not assume your allowance will work there.
How much roaming data do you get?
This is where giffgaff differs from almost every other UK network, and it is the single most important thing to understand before you travel.
You get a maximum of 5GB of data to use in the EU zone, taken from your plan's allowance. Crucially, that 5GB is counted per plan, not per month and not per trip. On most networks a roaming cap resets every month, so a 12GB cap means 12GB each month you are away. On giffgaff, the 5GB is the total you can use from a single goodybag while roaming, however long that goodybag lasts and however many separate trips you take on it.
If your plan includes less than 5GB of UK data, your roaming cap is simply that smaller amount. If it includes more than 5GB, you are still limited to 5GB while abroad. Calls and texts are unlimited within the EU zone and back to the UK.
What happens if you go over the limit?
When you reach your 5GB roaming cap, your data does not simply stop dead, but what happens next depends on whether you have credit and whether you buy an add-on.
By default, data used beyond the 5GB cap is charged at 10p per MB. That works out at roughly £100 per GB, so it is not a rate you want to drift into unawares. These out-of-bundle charges come out of your giffgaff credit, so keeping little or no credit on the account acts as a natural brake on runaway data costs, and you can tighten that control further by switching on giffgaff's credit spend cap.
The better option if you need more data is a travel data add-on, bought in the giffgaff app. These give you a block of roaming data at a far lower effective rate than 10p per MB, and they can be used across the whole EU zone on a single purchase. If you are running low, with less than 500MB of plan or roaming data left, giffgaff also lets you start your next plan early to refresh your allowance.
Roaming outside Europe
Outside the EU zone, giffgaff plans include no roaming allowance at all. Your goodybag data does not extend to countries like the USA, so without action your phone will not have usable data there.
The route giffgaff offers is the travel data add-on, but outside the EU these cover a short list of countries: China, Switzerland, Türkiye, and the USA. Prices are higher than the EU add-ons and vary by country. For the USA and Türkiye, an add-on costs £6 for 1GB, £12 for 5GB, or £18 for 10GB. For China and Switzerland it is steeper still, at £15 for 1GB, £30 for 5GB, or £45 for 10GB. Unlike the EU add-ons, a non-EU add-on is tied to the specific country you buy it for, so you need a separate add-on for each country you visit. They are data only, valid for 30 days from purchase, and bought through the app. For any non-EU country not on that list, or for heavy data use, a local eSIM is usually cheaper than giffgaff's roaming options. Add-on coverage and prices can change, so confirm in the app before you travel.
The 63-day rule and fair usage abroad
giffgaff's inclusive EU roaming is built for travel, not for living abroad. You get EU roaming for up to 63 days, and that entitlement depends on having used giffgaff in the UK in the 63 days before you arrive. Stay longer and giffgaff sends a warning text, then a second text confirming Roam Like at Home has been switched off, after which you are charged from your credit.
There is a worthwhile exception. Buying a travel data add-on lifts the 63-day limit for as long as that add-on is valid, so a longer trip is possible if you are willing to pay for the data rather than rely on the inclusive allowance. If you spend very little time in the UK over the longer term, your roaming eligibility can lapse entirely, and the only way to restore it is to return to the UK and use your phone here. This makes giffgaff a poor fit for digital nomads or anyone based abroad for months at a time, even though it serves ordinary holidaymakers well.
What a typical trip actually costs
Consider a two-week holiday in Spain on a giffgaff goodybag that includes more than 5GB of data, with moderate use of maps, messaging, and some streaming, totalling around 7GB across the fortnight.
The first 5GB comes out of your plan at no extra cost. The remaining 2GB is the question. Left to default rates, 2GB at 10p per MB would be around £200, which no sensible traveller should pay. The right move is a travel data add-on bought in the app before you cross the 5GB line. EU zone add-ons are priced at £4 for 1GB, £8 for 5GB, or £12 for 10GB, valid for 30 days, so the extra data for this trip costs a few pounds rather than a few hundred. The practical lesson is that giffgaff is genuinely free for trips that stay under 5GB on a single plan, and for anything beyond that you should treat the add-on, not the 10p per MB rate, as the real price of extra data. Add-on prices can change, so it is worth a glance in the app before travelling.
How giffgaff roaming compares
giffgaff's 5GB EU allowance is modest by current standards, and the per-plan rather than per-month structure makes it tighter still for longer or repeated trips. Among budget networks, both iD Mobile and Lebara include a far more generous 30GB roaming allowance, and SMARTY includes 12GB, all counted per month rather than per plan. Their over-limit terms differ too: iD adds a £3 per GB surcharge beyond 30GB, while SMARTY lets you buy a pass to unlock your full UK allowance. If EU data volume is your priority, giffgaff is not the strongest budget choice.
Where giffgaff earns its place is the wider package: O2-based coverage, no contract, the spend-cap protection, and the breadth of non-EU add-on destinations for travellers who go further afield than Europe. For a light-data holidaymaker who values flexibility and simple bill protection, it is a sound pick. For a data-hungry traveller, the networks above offer more for similar money.
How to check and manage your roaming
Before you travel, make sure roaming is enabled on your giffgaff account and that your phone's data roaming setting is switched on. In the giffgaff app you can switch between your UK allowance and a Travel Data view that shows your inclusive EU data, any add-ons, and your balance for the country you are in. Travel data add-ons are bought in that same Travel Data section, and you will need a debit or credit card to buy one.
To protect against unexpected charges, switch on the credit spend cap so out-of-bundle data cannot run away from you. If you are moving to giffgaff from another network and want to keep your number, our PAC code transfer guide explains how.
Roaming FAQs
Does giffgaff roaming work in Switzerland or Turkey?
Not on your inclusive allowance. Both Switzerland and Turkey sit outside giffgaff's EU zone, so your plan's data will not work there by default. You can buy a country-specific travel data add-on: for Türkiye that is £6 for 1GB, while Switzerland is much pricier at £15 for 1GB, so for a Swiss trip a local eSIM is often the cheaper option.
Can I buy more data if I use up my 5GB in the EU?
Yes. You can buy a travel data add-on in the giffgaff app, priced at £4 for 1GB, £8 for 5GB, or £12 for 10GB in the EU zone, which is far cheaper per GB than the default 10p per MB out-of-bundle rate. If you have less than 500MB of allowance left, you can also start your next plan early to refresh your data.
Does the 5GB cap reset every month?
No, and this is the most common misunderstanding. The 5GB is a maximum per plan, not per month or per trip. It is the total roaming data available from a single goodybag, regardless of how long that plan lasts.
Will giffgaff roaming work without a plan?
On pay as you go without a plan, you pay standard roaming rates from your credit rather than getting the inclusive EU allowance. You also need credit in your account for any out-of-bundle or non-EU data to work at all.
How long can I stay abroad on giffgaff?
Inclusive EU roaming lasts up to 63 days, provided you used giffgaff in the UK in the 63 days before arriving. Buying a travel data add-on lifts that limit for the duration of the add-on.
Best for: Occasional EU holidaymakers who use under 5GB of data per plan and value O2 coverage, contract-free flexibility, and simple bill-shock protection. Heavy data users and anyone travelling for months at a time should look at iD Mobile or Lebara for their larger, monthly-resetting allowances instead.
