Three's awkward problem is internal competition. It owns the network that 48 uses, yet 48 sells unlimited 5G at €12.99 on rolling terms. Vodafone has similar pressure from Clear at €12.99 on Vodafone radio. So this comparison is less "which network exists" and more "what premium are you willing to pay for owning-brand service and features".
If price is the main goal, check 48 vs Clear after this page. If you insist on direct MNO contracts, Vodafone usually lands as the better buy.

Price: Vodafone Red 15 beats Three Core at €20
Vodafone Red Unlimited SIM Only 15 is €15 in our August 2026 data. Three SIM Core starts at €20. That is €180 against €240 over the 12-month term, before April: both now carry a fixed €2.50 a month increase every April on SIM-only bill pay, applied inside the term (Vodafone on contracts from 16 October 2024, Three on contracts from 30 July 2025; Three’s handset plans get €3). Prepay is exempt on both.
Three has teaser structures like SIM Freedom €14 for 6 months then €28 on 24 months. Vodafone's value plan is cleaner if available at your checkout.
Network: both are MNOs, both strong
Both Vodafone and Three are MNOs with their own Irish network infrastructure. This is a true owner-vs-owner comparison.
Coverage performance is still local. A good map in your area beats any national marketing claim.
Data and plan structure: Three has more variants, Vodafone cleaner
Both have unlimited options across most tiers. Three has multiple plan variants including high-cost Flex and prepay unlimited structures. Vodafone also has a ladder, but the recommended value anchor is clearer at Red 15.
From a buyer perspective, less confusion is a benefit.
Contract: both use 12-month terms, but Three has long teaser paths
Vodafone direct plans are typically 12-month terms in the listed products. Three mixes 12-month with 24-month teaser-driven structures like Freedom. Both apply a fixed €2.50 April rise inside the term, and both offer eSIM on bill pay, so neither of those separates them.
The longer teaser path at Three can look cheap early but expensive over full term.
Roaming: Three can run higher on some tiers
Three lists 35 GB on Core and up to 60 GB EU roaming on Freedom and Flex. Vodafone Red Unlimited 15 includes EU roaming without a printed gigabyte figure; Vodafone Ultra lists 80 GB EU roaming but at a higher €35 price point.
At mainstream value tiers, both include EU roaming. On premium roaming-heavy tiers, results depend on which expensive plan you compare.
Who it's for: Vodafone for value, Three for brand-loyal perks
Vodafone suits buyers who want direct MNO service at the lowest direct-MNO monthly outlay. Three suits users who specifically want the Three account ecosystem and accept higher pricing.
If you just need cheap unlimited 5G, both can be beaten by MVNOs on their own networks.
