The best student mobile deal in Ireland is currently 48 Student 100 GB at €10.99. It needs a college email at sign-up and runs on Three radio. If 100 GB is enough, it undercuts every mainstream unlimited plan.
If you want unlimited data, the practical student floor is €12.99 from 48, Clear, and GoMo. That gives students a choice across Three, Vodafone, and Eir host networks without paying premium rates.
Top student picks in August 2026
48 Student 100 GB is the clear price winner for students who do not need full unlimited. It is rolling monthly and cheaper than most prepay alternatives for high-data use.
For students who stream heavily, unlimited 5G at €12.99 from 48, Clear, or GoMo is usually safer than squeezing into a 100 GB cap. Note that Clear and GoMo each add a €12.99 activation fee up front; 48 does not, and 48 is plastic SIM only, where GoMo offers eSIM.
When 100 GB is enough, and when it is not
100 GB is big for lectures, maps, and normal social use. It can run out if you tether to a laptop daily, watch frequent HD video off Wi-Fi, or use hotspot gaming. In that case, the extra €2 per month to 48 unlimited can be worth it.
Remember that 48 student requires a college email and is listed as 4G, not 5G. Students who care about 5G speed should compare the €12.99 unlimited options.
Student trap to avoid: teaser contracts
Student budgets are hit hardest by intro cliffs. Tesco Elevate at €15 then €30 and Eir Connect at €14.99 then €29.99 can look manageable in term one, then hurt in year two.
Students who move often are usually better on rolling plans than 12-month contracts, unless a contract plan has a specific roaming benefit they will actually use.
How we rank student plans
Student ranking favors low monthly cost, no lock-in, and clear data allowances. We also value host-network transparency because campus coverage can vary sharply by location.
