Sky Mobile vs Virgin Mobile: the two TV-company SIMs, on different masts

Price: Sky is €12.99 unlimited, Virgin is €15, and Sky has a €10 row

Unlimited is €12.99 a month on Sky and €15 on Virgin, both 12-month terms, no activation fee listed on either plan page. Year one is €155.88 on Sky against €180 on Virgin — about €24 in Sky’s favour for a faster SIM. Sky advertises the €12.99 as a cut from €15, so confirm the post-term price on the order summary; Virgin’s €15 is the same in year two by promise.

Sky also sells a 10 GB plan at €10. Virgin does not have a light row at all; it is €15 unlimited or nothing. If your phone lives on Wi-Fi, that is €60 a year back in your pocket with Sky, and the Piggybank means a quiet month is not a wasted month.

Virgin answers with the broadband bundle. Virgin Media broadband customers can typically add a second SIM at €9.99 for 12 months, after which it steps to €14.99. Sky does not list an equivalent mobile discount for Sky TV or broadband customers on its Irish plan page, so do not assume one is coming.

Sky now sits exactly on the cheap unlimited floor: Clear is €12.99 on the same Vodafone radio, rolling monthly, no contract, first month free. Virgin is €2 a month above 48, which is €12.99 on Virgin’s own Three radio. The TV-company SIM has to earn the 12-month term with roaming, rollover, or one bill.

Network: Sky rides Vodafone, Virgin rides Three — test a phone on each first

This is the part most people get wrong. Sky is an MVNO on Vodafone: Sky Group’s September 2024 launch release names a long-term wholesale partnership with Vodafone. Virgin is an MVNO on Three — Virgin’s own site does not name the partner, but every independent MVNO list does, and Virgin’s owner Liberty Global was in talks to buy Three Ireland in early 2026. Neither brand owns a tower here. The logo on the SIM tells you who sends the bill, not who carries the signal.

So “which has better coverage” has a local answer, not a national one. Vodafone claims about 98 per cent population coverage and Three 99 per cent, but they use different mast sites and spectrum, and they diverge most in rural Ireland and indoors. The honest test is free: borrow a phone on Vodafone (Vodafone, Clear or An Post are all Vodafone radio) and one on Three (Three, 48 or Tesco Mobile) and check bars in the rooms you actually use. If Three drops to one bar in your back bedroom, Virgin drops with it — and Sky, on Vodafone, may not. Our best mobile network in Ireland guide and the rural mobile page explain where the three radios tend to differ.

The second difference is the generation. Sky lists 5G on both of its plans. Virgin states its SIM-only plans currently operate on 4G. So even where both radios are strong, Sky gets the faster layer where Vodafone has built it and Virgin is held to 4G on Three. Our data score for Virgin is 8.0 against Sky’s 8.8 largely for that reason.

Data: Sky has 5G and Piggybank rollover, Virgin has plain 4G unlimited

On unlimited, both are unlimited with fair-use. The difference is speed: Sky’s unlimited runs on Vodafone’s 5G, Virgin’s is capped at 4G on Three. For streaming and maps 4G is fine; for tethering a laptop or anything in a busy cell, Sky’s 5G is the better product.

Sky then rolls unused data into a Piggybank you can draw on for up to three years. On the 10 GB plan that matters. Use 4 GB in a quiet month and 6 GB waits for the month you go over. Over a year a light user can bank a comfortable cushion and never pay for unlimited.

Virgin has nothing to roll because everything is unlimited. That is simpler, and for a heavy user simplicity has a value. It also means Virgin cannot sell you less. If you are a light user, Virgin is asking you to pay €15 for 4G data you will not touch.

Not sure which you are? Check your phone’s own usage screen, then read how much data do I need. Most people under 10 GB are surprised by how little they actually use.

Contract: two 12-month terms, one "for life" promise

Both are 12-month SIMs. Neither lets you walk next month the way 48, Clear or GoMo do. Early exit can cost on either, so the 14-day cooling-off window is your only free escape.

Virgin writes the price into the contract as €15 for life: no annual rise during the term, and the same rate after it. That is a real promise at a time when the big networks add fixed or CPI-linked increases every spring. Sky’s plans are at a fixed monthly price for the 12-month term on the plans we list, and the €12.99 is advertised as a cut from €15, so Sky does not use the words "for life" and its Irish broadband and TV products do carry annual changes. Read the order summary.

Sky has eSIM, so a switch can be done from the sofa. Virgin is plastic SIM on the plan we list. Minor for most, decisive if you run a dual-SIM phone or travel with a second line. More in eSIM in Ireland.

If the 12 months is the deal-breaker, neither of these is your SIM. Read no-contract mobile plans instead.

Roaming: Sky roams like home, Virgin gives you a number

Virgin includes 37 GB of EU and UK roaming a month on the €15 plan. That is a big, clear number, and it is more than the 20 GB or so most €12.99 MVNOs write into their fair-use policy.

Sky says roam like at home in the EU and UK on both plans. On the 10 GB plan your 10 GB travels with you. On unlimited Sky states it does not impose a separate roaming limit, so you use data abroad as you would at home, fair-use still applying.

Which is better depends on how you travel. A fortnight in Spain with a family streaming in the apartment can get past 37 GB. Most people will not. The UK is covered by both, which matters for anyone crossing to Belfast or Holyhead often, because post-Brexit UK roaming is not guaranteed by EU rules.

Neither plan includes calls to foreign numbers from Ireland. If you ring family abroad, see best for international calls.

Who it's for: pick by the radio first, then by the bill you already pay

Sky household: take Sky if Vodafone works at your address, and take the €10 plan unless you know you burn more than 10 GB. Virgin household: Virgin is defensible if the €9.99 broadband second SIM is on offer, or if Three is the only radio that reaches your kitchen; for a single main line where both radios work, Sky is still €2 cheaper with 5G, and the TV logo is not worth paying more for a slower plan.

Only one radio works at your address: that settles it, and the TV logo is irrelevant. Vodafone only — Sky, or Clear at €12.99 without the 12 months. Three only — Virgin, or 48 at €12.99 without the 12 months. Neither — GoMo at €12.99 on Eir. Signal beats loyalty.

No TV bundle with either: there is less reason to be here. Sky still wins for unlimited at €12.99 with 5G and eSIM, and for a light user who values rollover. Virgin wins only for someone who wants a for-life price more than they want 5G. For everybody else, the rolling €12.99 SIMs in best unlimited mobile are the better starting point — Clear is Sky’s Vodafone radio and 48 is Virgin’s Three radio, both without the 12 months.
