Frequently Asked Questions

What is an eSIM and how does it work?

An eSIM is a digital SIM built into your phone. Instead of inserting a physical card, you scan a QR code or use an app to activate your mobile plan. It works exactly like a regular SIM for calls, texts, and data.

Which Irish networks support eSIM?

Vodafone, Three, Eir, and GoMo all support eSIM. Most budget networks (48, Clear, Lycamobile) still require physical SIMs. Check with your chosen provider before assuming eSIM is available.

Can I use eSIM and a physical SIM at the same time?

Yes, if your phone supports dual SIM. Most modern iPhones and Android phones allow one eSIM plus one physical SIM, letting you have two numbers or two networks simultaneously.

Is eSIM better than a physical SIM?

eSIM is more convenient for switching networks and travelling, but physical SIMs are easier to move between phones. For most users, either works fine. Choose based on your phone's capabilities and your provider's support.
