Graba SIM Europe plans: data, validity and total price

Each plan is a one-off price for one eSIM. It starts when it first connects in Europe, and hotspot use comes out of the same data.

Using your phone in Europe

Interrail and city breaks
Crossing a border by train, the eSIM moves to the next country’s network by itself. Signal drops briefly in long tunnels.
Switzerland
Not in the EU. Many Europe plans include it, but check the coverage list on the plan.
Turkey
Partly in Europe but outside the EU, and often left out of Europe plans.
The Balkans
Serbia, Bosnia and Herzegovina, Montenegro, Albania and North Macedonia are outside the EU and not on every plan.
  • 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.
  • If you are visiting one country only, a single-country plan often costs less than a Europe-wide one.

Is a travel eSIM cheaper than Three in Europe?

It depends on the trip. Comparing Three’s lowest published option with a Graba SIM plan of about 0.7 GB a day: 3 days, the eSIM is £1.51 less; 7 days, the eSIM is £7.01 less; 14 days, the eSIM is £14.51 less. Three’s price also includes your UK calls, texts and up to 12 GB of your UK data.

Does a Europe eSIM work in every European country?

Not always. Plans differ, especially for Switzerland, Turkey, the UK and the Balkans. Check the plan’s coverage list against every country on your route before you buy.

Is a Europe plan better than a single-country plan?

Only if you visit more than one country. For a week in Spain or Greece alone, the single-country plan for that country often costs less.
