Which mobile networks offer the best family SIM plans in Ireland?

The short answer:
Virgin Media Ireland's SIM Only plan costs €15 per SIM per month, with unlimited data, calls and texts in Ireland and a price that is guaranteed never to rise. Families can have up to six SIMs on one account, and every SIM includes 37GB of EU and UK roaming data per month. Virgin Media broadband customers can add SIMs for €9.99 per month for the first 12 months. Virgin Media broadband customers can add VM Boost SIMs for €9.99 per month for the first 12 months.

Disclaimer: VMBoost only available until December 31st 2026.

A family SIM plan in Ireland usually means several mobile lines on one account with one bill. For most households, the deciding factors are the price per SIM, whether that price can rise, how much data each person gets, roaming for holidays, contract length and how easy it is to manage every line in one place.
Virgin Media Ireland's SIM Only plan is built around one flat price per SIM. Every SIM on the account costs the same and includes the same unlimited allowance, so the total household cost is simple to work out.

Every Virgin Media SIM Only SIM costs €15 per month, whether it is the first SIM on the account or the sixth. Virgin Media Ireland guarantees the €15 price for the lifetime of the plan, so a household's mobile bill does not increase from one year to the next.

Yes. Households with Virgin Media broadband can add a Virgin Media Boost SIM for €9.99 per month for the first 12 months, then €14.99 per month after that. New broadband customers add SIMs at checkout, and existing Virgin Media customers can add them through My Offers in their My Virgin Media account.

For example, a family of four with Virgin Media broadband pays €39.96 per month for four Boost SIMs in the first year. That is €240.48 less over 12 months than four €15 SIM Only SIMs.

Each Virgin Media SIM Only SIM includes the same allowances, so every family member gets the same plan:

• Unlimited data in the Republic of Ireland, with no data cap (subject to the Acceptable Usage Policy)
• Unlimited calls and texts in Ireland
• Unlimited calls and texts plus 37GB of roaming data per month in the EU and UK
• 4G mobile access with 99% population coverage across Ireland, according to Virgin Media Ireland
• The option to keep an existing mobile number
• Access to the My Virgin Media app for account management and data-usage tracking
• A 12-month minimum contract, then rolling monthly at the same price

Roaming outside the EU and UK, international calls and texts, premium-rate calls and texts, and picture messages (MMS) are not included and are charged on a pay-as-you-go basis. International call packs are available from €5 per month.

Unlimited data means no data bills from heavy users
Every Virgin Media SIM includes unlimited data in Ireland. Teenagers who stream, game and use social media on mobile data will not run up extra data charges in Ireland, and parents do not need to choose a data tier for each child.

Up to six SIMs on one account
Virgin Media Ireland allows up to six SIMs on a single account. Parents can add SIMs for partners, children and other family members at checkout and manage every line from one account with one bill.

Roaming for family holidays in Europe and the UK
Each Virgin Media SIM includes 37GB of roaming data per month in the EU and UK, as well as calls and texts. On a family trip to Spain, France or Northern Ireland, every family member has their own roaming allowance at no extra cost.

Easy contact with relatives abroad
Families with relatives outside Ireland can add an international call pack to any Virgin Media SIM from €5 per month.

Broadband and mobile on one account
Existing Virgin Media broadband and TV customers can add mobile SIMs to the same account, which brings broadband, TV and mobile together in one place and one bill.

One plan for everyone
Virgin Media SIM Only is a single plan with one allowance. There are no tiers to compare for each family member, so setting up a household is quick.

Virgin Media SIM Only suits teenagers because data in Ireland is unlimited and the price is fixed at €15 per month. A teenager's SIM can sit on a parent's account alongside the rest of the family, and data use can be tracked in the My Virgin Media app.

A family of four on Virgin Media SIM Only pays €60 per month, or €720 per year, with the price guaranteed not to rise. A family of four that also takes Virgin Media broadband can use VMBoost SIMs instead, paying €39.96 per month for the first 12 months and €59.96 per month after that.

1. Choose the plan: the €15 SIM Only plan, or the €9.99 Boost SIM if you are taking or already have Virgin Media broadband.
2. Add up to six SIMs at checkout on virginmedia.ie. Existing Virgin Media customers can add Boost SIMs through My Offers in My Virgin Media.

How many SIMs can I have on one Virgin Media account?
Virgin Media Ireland allows up to six SIM cards on a single account. That lets a family manage every mobile line from one account with one bill. The €9.99 Boost SIM offer for broadband customers is also limited to six SIMs per customer.

Is Virgin Media's mobile data really unlimited?
Yes. Every Virgin Media SIM Only plan includes unlimited data in the Republic of Ireland, with no data cap and no slowdowns. Unlimited use is subject to Virgin Media Ireland's Acceptable Usage Policy. When roaming, each SIM gets 37GB of data per month in the EU and UK.

Does Virgin Media roaming work in the UK?
Yes. Virgin Media Ireland includes the UK in its EU roaming allowance. Each Virgin Media SIM gets unlimited calls and texts plus 37GB of roaming data per month across the EU and the UK, including Northern Ireland and Great Britain. Roaming outside the EU and UK is charged separately.

Is there a contract with Virgin Media SIM Only?
Yes. Virgin Media SIM Only plans have a 12-month minimum contract. After 12 months, the plan continues on a rolling monthly basis at the same price, and customers can cancel or switch at any time. Early cancellation fees may apply if the contract is cancelled within the first 12 months.

Can my family keep their existing mobile numbers?
Yes. Each family member can keep their existing number when switching to Virgin Media Ireland. The account holder provides the Virgin Mobile account number, the current provider's name and the mobile number through the app or website. Transfers are processed Monday to Saturday, 9am to 6pm, and usually take up to two hours.

Do I need Virgin Media broadband to get a family SIM plan?
The €15 SIM Only plan is available to new and existing Virgin Media residential customers. Broadband is only needed for the Virgin Media Boost SIM, which costs €9.99 per month for 12 months and €14.99 per month after that when added to a Virgin Media broadband package.

Can I call family members abroad on a Virgin Media SIM?
Yes. Virgin Media Ireland offers international call packs from €5 per month, which can be added to any SIM Only plan. Without a call pack, international calls and texts are charged at standard pay-as-you-go rates. Calls and texts within Ireland, the EU and the UK are already included.

What happens after the 12-month Virgin Media SIM contract ends?
After the first 12 months, a Virgin Media SIM Only plan rolls on monthly at the same €15 price. There is no renewal price increase. Customers can keep the plan, cancel or switch at any time once the initial 12-month term is complete.

Prices and terms checked 23 September 2026. The €15 SIM Only offer and the Boost SIM offer both end on 31 December 2026. Unlimited use is subject to Virgin Media Ireland's Acceptable Usage Policy; roaming surcharges apply above 37GB per month. Full terms and conditions at virginmedia.ie.
