Removing Paramount+ on Three UK Risks Inviting 100Mbps Data Speed Cap

Some existing customers of mobile operator Three UK, specifically those who have the Paramount+ add-on included with their ‘Complete‘ plan, have responded to the looming price hike on the streaming service by taking the option to remove it from their package. The catch is that doing so seems to require you to accept the operator’s new 100Mbps cap on mobile broadband speeds.

Back in April 2026 we reported that Three UK had moved to mirror Vodafone by introducing mobile broadband (4G, 5G) speed caps of between 25Mbps and 100Mbps (Megabits per second) across various mobile plans (here) – those still wanting “full speed” could take it via a £4 add-on. But this was only for new customers, while existing users with uncapped speeds could continue to enjoy it, at least until they needed to recontract.

The latest development relates to customers of Three’s Complete plans, which often came bundled with a free period of the Paramount+ streaming service and currently also offer the bonus of inclusive roaming in over 160 worldwide destinations. Sadly, such users were recently notified that “Paramount+ will increase from £7.99 to £9.99 a month from 27th August 2026 for new and existing customers“.

The problem, as spotted by one of ISPreview’s forum members and Three UK customer MissTuned (here), is not so much the price increase but the fact that when customers take the option to simply remove the add-on, Three UK then rather sneakily seems to change the rest of their contract to impose the 100Mbps speed cap too.

Three UK Customer MissTuned said:

Watch out with Three – they sent me an email about the price of Paramount going up. I have literally never used Paramount and never will, so I decided to go and remove the add-on from my account to avoid getting billed when the free period runs out.

At the very last moment in the “remove add-on” section, I noticed that the process would also change my speed cap to “up to 100Mbps”, they are sneaking it on with every account change you make! This is a contract that has quite a long time left to run, so it seems that they’re treating “get rid of Paramount” as a contract change which then allows them to hit you with the speed cap.

The other issue, as can be seen in the example screenshot below, is that Three also appears to propose an additional update to the customer’s inclusive roaming on the same plan. But unlike with the introduction of a speed cap, they don’t make completely clear what has actually changed with this one.

“It feels like they are using Paramount, which is a pretty useless also-ran TV streamer, as an add-on that people will want to cancel, and in cancelling it they’ll accidentally speed cap their package. There’s also the unspecified change to roaming, which isn’t clarified other than that the roaming allowance shows as “updated” when you go to remove Paramount, I presume the removal of some countries or partners,” complained MissTuned.

The related Paramount+ price increase notification page on Three’s website makes no mention of the additional caveats. Most operators usually treat adjustments to add-ons separately from wider package features. ISPreview has queried the situation with Three to clarify if this is a mistake or not, and we’ll report back as soon as they respond.
