Customers of Three UK, now part of the merged VodafoneThree operator, received an unexpected notification indicating that the network is introducing download speed caps on most new and upgrading plans from mid-April 2026.
The move, which appears to have been implemented with minimal prior warning, introduces “Everyday Speeds” tiers across Pay Monthly, Pay As You Go (PAYG), and mobile broadband offerings.
Many existing customers on legacy plans remain unaffected for the time being, but those who upgrade or sign up for new contracts will face the new limits.
The message sent to customers reads as follows:
“We wanted to let you know about upcoming changes to our network. From 19 April, download speeds will be capped at 50Mbps for new customers. But good news – if you keep your current Auto-renew Data Pack active, you will continue enjoying uncapped speeds.”
This suggests that many long-term customers who avoid upgrading or re-contracting can keep uncapped access for now. However, over time, as people naturally move to newer plans, the caps are likely to become more widespread.
What are the speed caps?
- Pay Monthly plans (mobile and mobile broadband): New customers and upgraders are now limited to “up to 100Mbps” download speeds under the standard Everyday Speeds tier. This is positioned as faster than the UK average mobile download speed of around 72Mbps.
- Pay As You Go (PAYG) plans: Standard cap of up to 25Mbps. Certain Mobile Broadband data packs and standard-rate usage can reach up to 50Mbps.
- Full Speed option: Customers can pay an extra £4 per month for a “Full Speed Add-on” (or select plans that include it, such as Lite+), which removes the cap and allows access to the network’s maximum available speeds.
The changes are detailed in Three’s updated price guides dated 19 April 2026.
A degraded service
Three UK was previously known for offering relatively uncapped speeds on many plans, often as a point of differentiation in a competitive market.
The changes come roughly a year after the high-profile merger between Vodafone and Three, which created VodafoneThree and promised network improvements, including better coverage and speeds for millions of customers through shared infrastructure.
The new structure may reflect influences from Vodafone’s existing tariff approach, which has featured speed tiers in the past.
For most smartphone users, the 100Mbps cap is unlikely to cause major disruption. Real-world mobile speeds are highly variable depending on location, network congestion, and device, and many everyday tasks perform well below that threshold.
However, users relying on mobile broadband as a primary home internet connection, particularly in areas with strong 5G signals, may notice the difference more acutely if they previously achieved consistently higher speeds.
VodafoneThree has not commented further on the rationale beyond the initial statement. As the merged network continues to integrate and invest in its combined infrastructure, more details on long-term strategy may emerge.
