This eSIM gives you one data bundle for two countries: Ireland and the United Kingdom, which means England, Scotland, Wales and Northern Ireland. In Ireland it connects to Three and Vodafone, in the UK to O2, Vodafone and Three (in the UK, Vodafone and Three have been combined as VodafoneThree since 2025). The plans run on 4G, which is plenty for navigation, social media and app calls in Dublin, Cork, Belfast, London, Edinburgh and most tourist areas. In rural Ireland, along the Wild Atlantic Way and in the Scottish Highlands, the signal can drop out. Networks: Three (Ireland), Vodafone (Ireland), O2 (UK), Vodafone (UK), Three (UK).
For a one-week city trip to Dublin and London, 5 GB is enough. For a two-week road trip along the Wild Atlantic Way or through Scotland, 10 to 20 GB is a better fit, and the 50 GB plan stays valid for 180 days for a longer stay.
With a plan from an EU or EEA country, Ireland falls under roam-like-at-home, but the UK has been outside those rules since Brexit and each operator decides for itself. This eSIM gives you one bundle that works in both countries.

Yes. Our eSIM gives you instant mobile data in Ireland & UK on the local networks, with no roaming fees. Your phone needs to support eSIM and be carrier-unlocked.
It depends on your trip. For mostly maps and messaging, 1 to 3 GB is plenty. If you use navigation, social media and some streaming, plan for roughly 1 GB every two to three days.
Right after payment. You receive a QR code on screen and by email immediately. It is best to install it at home over Wi-Fi before you leave.
Yes. Your own SIM stays in your phone for calls and texts. The eSIM runs alongside it, purely for mobile data in Ireland & UK.
The cheapest eSIM for Ireland & UK at esimzu starts from €2,49, with a lowest-price guarantee. You pay in euros by Bancontact, card or crypto and receive the eSIM instantly by QR code, with no app or physical SIM card.
Not necessarily. Ireland is in the EU, so a plan from an EU or EEA country works there without a roaming surcharge. An eSIM mainly helps when your bundle allows little data abroad, when you also visit the UK, or when your plan comes from a country where the EU roaming rules do not apply. If you stay in Ireland only, also take a look at our Ireland-only eSIM.
That depends on your operator. The UK has not been covered by the EU roaming rules since Brexit, so even with an EU plan each operator chooses whether the UK is included in your bundle or charged separately. Check your terms before you leave, or use this eSIM so your data is sorted in both countries.
Yes, the whole United Kingdom is covered by this plan: England, Scotland, Wales and Northern Ireland. Jersey, Guernsey and the Isle of Man are not part of the UK and are not on the coverage list of this eSIM.
The eSIM switches to a network in the other country by itself, so there is nothing to set up. Near the border your phone sometimes picks up a network from the other side, but with this eSIM that makes no difference, because your data simply counts down from the same bundle.
