Same radio, different jobs. If you wanted Eir coverage and cheap Irish unlimited, that is GoMo, not Lycamobile’s “unlimited” teasers. If you wanted to ring Lagos or Manila more than you stream, Lycamobile. If Eir is the wrong radio at your address, neither: 48 is €12.99 on Three and Clear is €12.99 on Vodafone.
Both have eSIM. Both can keep your number. The rest of the comparison is whether your month looks like international calls or Irish data.

Price: 28-day bundles versus €12.99 forever
GoMo is €12.99 monthly with no listed jump, plus a €12.99 once-off activation fee: €168.87 in year one. Lycamobile’s cheap rows start at €4.99 data-only. Ireland Plus is €9 for six cycles. Unlimited Plus is €10 for six cycles then €25; Go Unlimited is €11 for 12 cycles then €20. National Unlimited is €12.99 plus a €12.99 activation fee, on 28-day cycles, so 13 a year.
A cheap Lycamobile voucher is not a cheaper GoMo. It is less Irish data, or a throttle, or minutes instead of data, or a promo that becomes €20 to €25 a cycle.
Network: the same Eir radio, so coverage is a draw
Lycamobile moved from Three to Eir in late 2025. GoMo is Eir’s own budget brand. Same masts, same 5G layer, same dead spots — indoor signal cannot pick this one, only the plan can.
Eir is retiring 3G from 1 October 2026, and that applies to Lycamobile and GoMo customers alike: an old 3G-only handset will stop working on either SIM. If Eir is the wrong radio at your address, neither SIM fixes it — look at 48 on Three or Clear on Vodafone.
Data: real unlimited versus 100 GB then crawl
GoMo is unlimited 5G with fair-use. Lycamobile Unlimited Plus and Go Unlimited are 100 GB at 5G, then 256 kbps. National Unlimited is listed as unlimited on the same Eir radio, with an activation fee.
Data-only XS to L is 3 GB to 20 GB. That is a tablet SIM, not a GoMo replacement.
Contract: both easy to leave
GoMo is rolling monthly at a for-life price. Lycamobile is 28-day prepay, but Unlimited Plus and Go Unlimited carry a promo price that steps up to €25 and €20 after six and twelve cycles. Neither is a 12-month Elevate-style trap; one of them still has a thereafter.
Miss a Lycamobile top-up and the bundle ends. Miss nothing on GoMo and it keeps billing.
Roaming: both list EU, Lycamobile adds extra countries on some rows
GoMo lists 23 GB EU. Several Lycamobile plans include EU, Ukraine and Moldova on the note. Caps are still caps.
Neither is a travel-eSIM product. 48’s HelloGlobe is travel-only too, and 48 is not in this matchup.
Who it's for: minutes home versus Irish data
Lycamobile is the international specialist. GoMo is the cheap Eir unlimited SIM. Same masts, so nobody should pick between them on coverage. If you landed here because both say unlimited, read the 100 GB throttle and pick again. They are different jobs.
Which should you choose?
It comes down to cost profile, host network fit, and contract style. Use this fast decision frame.
Choose Lycamobile if
You buy a SIM for international minutes and 28-day control. Country bundles matter more than a €12.99 Irish unlimited plan. You accept Eir radio and, on the "unlimited" teasers, a 256 kbps cliff after 100 GB.

Choose GoMo if
You want unlimited 5G in Ireland at €12.99 on Eir radio, for-life pitch, app-only support. International calling is not why you are shopping.
