CommunityFibre launches £15 unlimited 5G eSIM on VodafoneThree

Last reviewed: 10 July 2026

What CommunityFibre has launched

CommunityFibre, the London and South East full fibre broadband provider covering around 1.4 million UK premises, launched an unlimited UK mobile eSIM in July 2026, developed in partnership with Gamma Communications and app developer Zappter. The plan offers unlimited UK data, calls and SMS with tethering and hotspotting included, on a monthly rolling contract with no fixed-term commitment, activated entirely through the CommunityFibre mobile app rather than a physical SIM card. Pricing is tiered by existing relationship: £15 a month for customers who already hold CommunityFibre broadband, and £17 a month for anyone signing up for the mobile plan alone. The structure positions the eSIM as a retention and cross-sell tool for the broadband base as much as a standalone mobile product, consistent with CommunityFibre's own framing of the launch as extending value across its combined broadband and mobile customer relationship.

Correcting the network claim

CommunityFibre's own marketing and coverage of the launch describe the service using language about fast 5G connectivity without always specifying the underlying network operator. Verification against CommunityFibre's press materials and independent reporting confirms the eSIM runs on the VodafoneThree network, the single merged network formed from the Vodafone and Three UK combination, positioning CommunityFibre as a Mobile Virtual Network Operator, or MVNO, reselling capacity on that one network rather than switching between multiple operators. This distinguishes it clearly from genuinely multi-network products such as Fuse Mobile, which connects across EE, Three, Vodafone and O2 depending on signal strength. A CommunityFibre eSIM customer's coverage is therefore defined entirely by VodafoneThree's own network footprint in a given location, not by whichever of the four national networks happens to be strongest nearby.

How the price compares

Against other unlimited SIM-only plans, CommunityFibre's £15 non-discounted price sits toward the competitive end of the market without being the outright cheapest. Budget MVNO Smarty has offered unlimited SIM-only plans around £15 a month on the EE network for an extended period, giffgaff runs a limited-time unlimited eSIM offer at £20 a month on the O2 network, and spusu prices high-allowance but capped plans, such as 20GB for £7.90, considerably below either on a price-per-gigabyte basis for customers who do not need a genuinely unlimited allowance. CommunityFibre's own published comparisons claim savings of several hundred pounds over 24 months against Virgin Media and O2 SIM-only equivalents, though those figures come from the company's own marketing rather than an independent source and compare bundled broadband-plus-mobile scenarios rather than mobile pricing alone.

Prices as published by providers, July 2026. Plans vary in included extras such as roaming and international minutes; figures compare UK data, calls and SMS pricing only.

The separate travel eSIM

CommunityFibre's launch coverage also references a distinct travel eSIM product, offering country-specific roaming data bundles for more than 160 countries from £2.29, which predates the unlimited UK launch and operates as a separate purchase rather than an add-on to the £15/£17 unlimited plan. Anyone comparing CommunityFibre's mobile offering against roaming-inclusive products, such as Fuse Mobile's higher tiers which bundle 130-plus country coverage into the monthly price, needs to treat the two CommunityFibre products as distinct purchases with distinct pricing, rather than assuming the unlimited UK eSIM includes international use.

The prepaid, per-country structure of the travel eSIM also differs functionally from an inclusive roaming allowance. A traveller visiting several countries on one trip would need to purchase separate bundles for each destination, or a wider regional bundle where available, rather than relying on a single allowance that works everywhere automatically. For occasional travellers this can still work out cheaper than a roaming-inclusive monthly plan priced for year-round use, but it requires planning ahead of a trip rather than simply crossing a border and continuing to use the same allowance, which is the trade-off against a product like Fuse Mobile's always-on international coverage.

Who the product suits

A single-network MVNO on VodafoneThree is a reasonable option for a household already inside VodafoneThree's coverage footprint, particularly one already paying for CommunityFibre broadband and able to access the discounted £15 rate, where the pairing produces a genuine combined saving over separately priced broadband and mobile contracts. It is a weaker fit for anyone in an area where VodafoneThree coverage is patchy relative to other networks, or anyone specifically seeking the coverage-resilience benefit of a multi-network product, which this eSIM, despite some marketing language implying broad 5G reach, does not provide.

Handset compatibility and the eSIM shift

The plan requires an eSIM-capable handset, broadly meaning iPhone XS and later, and most Android flagships released from around 2020 onwards, though exact compatibility varies by manufacturer and UK model variant. CommunityFibre's own research, cited in its launch materials, estimates that roughly 60 to 75% of smartphones currently in use in the UK are eSIM-capable, rising to close to 100% of new handsets sold, putting the addressable market for an eSIM-only product at somewhere between 32 and 40 million devices nationally. That figure explains the timing of the launch: eSIM-only pricing structures, which avoid the cost of issuing and posting physical SIM cards, have only become commercially viable at consumer scale as handset compatibility has caught up, and CommunityFibre's decision to launch eSIM-only rather than offering a physical SIM alternative reflects that shift rather than a cost-cutting choice specific to this product.

Frequently asked questions

How much does the CommunityFibre unlimited eSIM cost?

£15 a month for existing CommunityFibre broadband customers, and £17 a month for anyone taking the mobile plan without CommunityFibre broadband. Both include unlimited UK data, calls and SMS on a monthly rolling contract.

Which network does the CommunityFibre eSIM use?

The VodafoneThree network. It is a single-network MVNO service, not a multi-network product that switches between operators.

Does the plan include roaming?

No. The £15/£17 unlimited UK plan does not include international roaming. CommunityFibre sells a separate travel eSIM with country-specific bundles from £2.29, covering more than 160 countries.

Is a physical SIM card needed?

No. The service is eSIM only, activated through the CommunityFibre mobile app on a compatible smartphone or tablet.

Is CommunityFibre's eSIM cheaper than other unlimited SIM-only plans?

It is competitive but not always the cheapest. Smarty has offered unlimited SIM-only plans around a similar £15 price on the EE network, while giffgaff's limited-time unlimited eSIM costs £20 on O2. The comparison depends on which network's coverage suits the user's location.
