Can I get a prepay eSIM?
Yes, most major providers now offer prepay eSIMs. While they were initially reserved for “bill pay” (contract) plans, you can now get them from the big networks like Vodafone, Three, and Eir right from the start. It is worth noting that you cannot always choose an eSIM directly when you first sign up. In some cases, you might need to buy a physical SIM card first and then request a switch to an eSIM later.
Your provider’s website should clearly state their specific process, but you can always contact their customer support if you are unsure.
What do you need to activate a prepay eSIM?
To use a prepay eSIM, you need two things: a handset that supports eSIM technology and a mobile provider that offers eSIMs for prepay customers. While most major Irish networks support eSIMs for contract plans, only a selection currently offer them for prepay. We list the current options in the table at the top of this page.
How to get a prepay eSIM
- Select your deal: Choose the prepay plan you want on the provider’s website.
- Enter your details: Fill in the required information and select “eSIM” as your SIM type.
- Checkout: Complete the purchase or your initial top-up.
- Activate: The provider will send you a QR code, usually via email. Scan this code with your phone to activate the service.
The process above is the standard method, but the exact steps can vary between networks.

What are the advantages of a prepay eSIM?
The biggest advantage is getting connected almost instantly. If your provider allows you to choose a prepay eSIM when you order, you can be up and running in minutes. There is no more waiting around for a physical SIM to arrive in the post, and you won’t have to go looking for a tool to open your SIM tray.
Another handy feature of eSIMs is the ability to use two numbers on one phone (called Dual SIM). This is ideal if you want to keep your work and personal numbers separate or if you are visiting Ireland and want a local prepay plan alongside your home SIM. Additionally, eSIMs are a more sustainable choice as they cut down on plastic waste and delivery emissions.
Are there any drawbacks to an eSIM?
The main drawback is that the setup can sometimes be slightly more technical than just “plug and play” with a physical SIM. It can also be a bit more complicated to move your eSIM if you switch to a new phone. While some manufacturers offer “quick transfer” features, you usually have to contact your provider for a new QR code to move your plan to a different handset.
Can I switch from a physical SIM to a prepay eSIM?
Yes, most providers that support eSIM will allow you to swap your current physical prepay SIM for an eSIM. For example, Vodafone allows you to manage this through your online account or by visiting one of their stores.
Lycamobile has also simplified things lately; you can now often select an eSIM directly during the online checkout, though existing customers can still swap via their My Lycamobile account.
Which is the cheapest prepay eSIM deal?
Lyca Mobile National Unlimited is the cheapest prepay eSIM deal right now (checked on 29/09/2026). Top up from €0.00/month for 1 months, then €12.99/month.
Frequently asked questions about prepay eSIMs
In Ireland, most major networks do not charge an extra fee for an eSIM. It is typically included as part of your initial top-up or provided as a free swap if you are moving from a physical SIM card. However, always check the specific terms of your provider, as some smaller MVNOs (mobile virtual network operators) may have different policies.
Not yet. While the main networks support it, some popular budget MVNOs still primarily use physical SIMs for their standard plans. If you’re looking for the absolute lowest price, you might still be tied to a plastic SIM for now. But always check the compatibility or “SIM types” section on the provider’s website before you buy.
Yes, if your prepay plan includes 5G data and you have a 5G-ready handset, it will work perfectly with an eSIM. The eSIM technology itself doesn’t limit your network speed; it’s your specific prepay plan and local network coverage that determine whether you get 5G or 4G.
Absolutely. This process is called “porting.” When you sign up for a prepay eSIM deal, you can choose to move your existing Irish mobile number (starting with 083, 085, 087, or 089) to your new provider. You will usually receive a temporary number first, and once the eSIM is activated, you can complete the move via the provider’s app or website.
Yes, Irish prepay eSIMs follow the same “Roam Like at Home” regulations as physical SIM cards. This means you can use your data, calls, and texts while travelling within the EU/EEA, though most providers apply a “fair usage policy” on the amount of data you can use abroad. Check your provider’s app to see your specific roaming data limit.
The main reason is convenience. You can download and activate your plan in minutes without waiting on the post. It’s ideal for people who want to keep two numbers on one phone – for example, a work number and a personal prepay number. eSIM is also a great option for tourists visiting Ireland who want a local prepay plan alongside their home SIM.
