Graba SIM vs Airalo: the same plans, side by side
Plans with exactly the same data allowance and validity for Europe, both data-only and priced in pounds. Coverage and networks can differ, so check the plan details before you buy.
Highlighted: the lower price for each plan. Holafly sells unlimited data only, priced in US dollars, so it isn’t in this like-for-like table.

Know before you go
- Many UK plans still include some roaming in Europe, often for a daily charge. Check your plan first: if Europe is included at no extra cost, you may not need an eSIM.
- Europe plans differ in which countries they include. Check Switzerland, Turkey and any non-EU stops on your route against the plan’s coverage list.
- If you are visiting one country only, a single-country plan is often cheaper than a Europe-wide one.

Set it up before you leave the UK

Questions UK travellers ask
What is the best eSIM for Europe from the UK?
It depends on how much data you use. For most travellers a fixed-data plan of 3 to 10 GB is enough, and it is often cheaper than paying a UK network’s daily roaming charge for the whole trip. Pick a plan whose validity covers your whole trip and whose coverage list includes every country you visit.
Is an eSIM cheaper than roaming with EE, O2, Vodafone or Three?
Often, for trips of more than a few days. UK daily roaming charges add up each day you use your phone, while an eSIM is a one-off price. If your UK plan already includes Europe at no extra cost, use that.
Will I keep my UK number?
Yes. The eSIM is data-only and your UK SIM stays in your phone, so you can still receive texts such as bank codes. WhatsApp and iMessage keep working over the eSIM’s data.
When should I install it?
Before you fly, at home on Wi-Fi. Then switch it on when you land. Check the plan details for when its validity starts.
