Three Customers Removing Paramount+ Could Face a 100Mbps Speed Cap
Some existing Three customers on older Complete-plan arrangements could lose legacy uncapped mobile speeds if removing Paramount+ causes their plan to move onto Three's newer terms
Some older Three Complete-plan customers who try to remove their included Paramount+ benefit may be asked to accept Three's newer airtime-plan terms — including an "everyday speed" limit of up to 100Mbps.
The issue was reported by ISPreview on 10 August 2026 after existing customers noticed that removing Paramount+ appeared to involve more than simply deleting a streaming add-on. For affected legacy customers, the process could also change the underlying mobile plan and introduce the speed limit now used across Three's current mainstream Pay Monthly plans.
This does not mean every Three customer who cancels Paramount+ suddenly gets capped. Customers already on Three's newer Lite, Value and Complete plans are normally advertised at up to 100Mbps already. The concern is mainly for some older customers who still have legacy plan terms with access to faster uncapped 5G speeds.
What has happened?
Three includes a Paramount+ Standard Monthly Plan with its Complete airtime plans. The streaming service is also available as a paid add-on on other eligible Three plans.
Three is currently warning that the chargeable Paramount+ Standard Monthly Plan will increase from £7.99 to £9.99 per month from 27 August 2026 for new and existing customers who pay for the service.
Against that backdrop, some existing Complete-plan customers have looked at removing Paramount+ from their account. ISPreview reports that for some older customers the removal journey appears to require acceptance of Three's newer plan structure, including its 100Mbps mobile-data speed cap.
Three says the chargeable Standard Monthly Plan rises from £7.99 to £9.99 from 27 August 2026.
Three advertises its current mainstream Pay Monthly plans with speeds of up to 100Mbps.
Three currently lists a £4-per-month Full Speed add-on for eligible Pay Monthly customers.
Do not press through a plan-change screen without reading it. If your old Three tariff currently has uncapped speeds, removing an entertainment benefit may be a poor trade if the transaction also migrates your airtime plan onto a 100Mbps limit.
Who could actually be affected?
The distinction between legacy plans and Three's current plans is essential. Three introduced the 100Mbps limit for new and upgrading Pay Monthly customers in 2026. Customers who had not changed their older plan could therefore still have different speed terms.
| Customer situation | Likely position | Why it matters |
|---|---|---|
| Older Complete customer with legacy uncapped speeds | Check carefully | This is the group at the centre of the report. Removing Paramount+ may trigger acceptance of newer plan terms. |
| Current Complete-plan customer | Already up to 100Mbps | Three's current Complete plan is already advertised with everyday speeds of up to 100Mbps. |
| Current Value-plan customer | Already up to 100Mbps | Value is also currently advertised at up to 100Mbps. |
| Current Lite-plan customer | Already up to 100Mbps | Lite uses the same headline everyday-speed limit. |
| Lite+ customer | Full Speed included | Three says Lite+ includes its Full Speed add-on rather than the standard 100Mbps cap. |
| Customer who buys the Full Speed add-on | Faster speeds possible | The add-on removes the standard speed restriction, but real speed still depends on coverage, signal, congestion and device capability. |
Most important point: the headline is about some existing legacy customers. It would be inaccurate to say that cancelling Paramount+ universally causes Three to impose a new 100Mbps cap.
How Three's current speed limits work
Three's own Full Speed support page currently states that its Pay Monthly plans come with everyday speeds of up to 100Mbps. Its Three Your Way page separately lists the same 100Mbps figure for Lite, Value and Complete.
Three also offers Lite+, which includes its Full Speed add-on, and eligible customers can currently buy the Full Speed add-on separately for £4 per month.
| Current Three plan | Advertised speed position | Selected extras |
|---|---|---|
| Lite | Everyday speeds up to 100Mbps | 5G ready, calls/texts, Three+; Paramount+ optional |
| Lite+ | Full Speed | Full Speed add-on included |
| Value | Everyday speeds up to 100Mbps | European roaming, extended warranty with eligible device plans; Paramount+ optional |
| Complete | Everyday speeds up to 100Mbps | Paramount+ included, wider roaming and additional device-plan benefits |
A 100Mbps cap is not the same as poor signal. It is a maximum plan speed. Actual performance can be lower because of coverage, congestion, indoor reception, device capability and network conditions.
Why could removing an add-on change the speed?
The unusual part of this story is that consumers may reasonably expect removing a streaming benefit to affect only the streaming benefit. But an older Complete customer may be on a tariff structure that Three no longer sells to new customers.
If Three's account system handles the removal by rebuilding or migrating the customer's airtime package onto its current Three Your Way plan structure, other contractual features can potentially change at the same time. That is why the final checkout or contract-change summary matters.
Legacy plan
An existing customer may still have older tariff terms, potentially including uncapped data speeds.
Remove Paramount+
The customer starts a change to remove the included entertainment benefit from the account.
New plan terms
If the change migrates the airtime plan, the customer may be shown newer terms including the 100Mbps limit.
The speed cap is not necessarily a fee for cancelling Paramount+. The better interpretation is that some plan-change journeys may migrate an older tariff onto Three's current product rules.
What is happening to the Paramount+ price?
Three's Paramount+ page currently carries a notice stating that the Paramount+ Standard Monthly Plan will increase from £7.99 to £9.99 a month from 27 August 2026 for new and existing customers.
That is a £2 monthly increase, equivalent to £24 over a full year if the price stayed at £9.99 for all 12 months.
However, customers need to distinguish between a chargeable Paramount+ add-on and Paramount+ that is included as a benefit for the full length of an eligible Complete plan. Three's current Complete-plan marketing says the Standard Monthly Plan is included with Complete at no extra charge for the plan term.
The Standard Monthly Plan price shown by Three before the August increase.
Three's current notice gives this as the new monthly charge for chargeable subscriptions.
A £2 monthly increase equals £24 over 12 months, assuming the same price throughout.
Complete customers should check their own contract. Do not assume a general Paramount+ price increase means your inclusive Complete-plan benefit suddenly costs £9.99. The account and contract wording for your specific plan is what matters.
Is a 100Mbps mobile speed cap actually a problem?
For normal phone use, 100Mbps is still fast. Three itself says this level is enough for 4K streaming, online gaming and high-quality video calls.
The issue is therefore less about whether 100Mbps makes a phone unusable and more about whether a customer is being asked to give up a feature they already have. A strong Three 5G connection can be capable of substantially more than 100Mbps, so customers who regularly download large files, tether laptops or use mobile data as their main internet connection may notice the difference.
- ✓Web browsing and social media
- ✓HD and 4K video streaming
- ✓Video calls
- ✓Music streaming
- ✓Most mobile gaming
- !Very large app and game downloads
- !Using a phone as a high-speed hotspot
- !Large cloud backups and file transfers
- !Replacing fixed broadband with mobile data
- !Users in locations where Three 5G routinely exceeds 100Mbps
Latency is different from download speed. A 100Mbps cap does not automatically make gaming laggy, and an uncapped plan does not guarantee low latency. Signal quality, routing and network congestion still matter.
Can you remove Three's 100Mbps cap?
Three currently lists a Full Speed add-on for £4 per month for Pay Monthly customers. Its support page describes the add-on as providing faster download speeds, while the Three Your Way page says Lite+ includes Full Speed as part of the plan.
Full Speed does not guarantee one specific number. It removes the standard plan restriction, after which the speed you actually receive depends on the network and device.
| Option | Speed position | Current published cost |
|---|---|---|
| Standard current Pay Monthly plan | Up to 100Mbps everyday speed | Included in plan |
| Full Speed add-on | Restriction removed | £4/month |
| Lite+ | Full Speed included | Depends on selected tariff |
Consider the maths before changing an old plan. If removing a benefit saves money but you then pay £4 every month to restore Full Speed, the net saving may be smaller than expected.
What should you check before removing Paramount+?
If you are an existing Three customer, especially one who joined before the current speed-cap structure appeared, treat the change as a possible airtime-plan modification rather than assuming it is only a streaming cancellation.
Record your current plan
Take screenshots or save the current contract information showing your tariff, monthly price, included benefits and speed terms.
Read the change summary
Before confirming removal, look for wording about speeds, minimum term, roaming, warranty, screen repair and monthly cost.
Stop if terms worsen
If the screen shows a 100Mbps cap or other unwanted changes, do not confirm until Three explains exactly what will happen to your account.
- !Uncapped or Full Speed mobile data
- !Inclusive roaming destinations or passes
- !Legacy discounts
- !Warranty or screen-repair benefits
- !Existing minimum-term conditions
- ✓Current bill
- ✓Current contract summary
- ✓Screenshot of any warning or speed change
- ✓Date and time of any customer-service conversation
- ✓Any confirmation email or SMS
How Three says Paramount+ can be cancelled
For chargeable Paramount+ subscriptions managed through Three, Three's support information says customers can remove the subscription in the Three app or My3.
- Log in to the Three app.
- Open Manage Add-on.
- Select Remove on the Paramount+ card.
- Confirm the removal.
- Continue to checkout.
- Log in to My3.
- Select the Plan area.
- Scroll to Manage Add-ons.
- Select Remove for Paramount+.
- Review and complete the checkout process.
For legacy Complete customers, the final checkout step is the crucial one. If it displays changes beyond Paramount+, read them carefully and contact Three before completing the transaction if anything is unclear.
Why older Complete customers should be cautious
Three's current Complete plan is a bundle rather than simply a basic mobile tariff with Paramount+ bolted on. It combines the mobile service with other benefits, including roaming and, on eligible device plans, additional warranty or repair features.
That makes it possible for a legacy customer's account change to involve the broader tariff rather than one isolated entertainment subscription. The exact impact depends on the customer's existing contract and the terms displayed by Three when the change is made.
Best consumer approach: if the saving from removing Paramount+ is important, ask Three whether it can remove or adjust the entertainment benefit without changing your legacy airtime speed terms. Get the answer in writing or retain the chat transcript where possible.
What this story does not mean
| Claim | Accurate? | Better explanation |
|---|---|---|
| “Three has just capped every customer's 5G at 100Mbps.” | No | Three introduced the cap on its newer plan structure earlier in 2026; some existing legacy customers retained older terms. |
| “Cancelling Paramount+ always causes a speed cap.” | No | The reported issue concerns some older Complete-plan customers and appears linked to migration onto newer tariff terms. |
| “100Mbps means Three's 5G network can only do 100Mbps.” | No | The cap is a retail-plan restriction, not the physical maximum capability of the 5G network. |
| “Complete plans have uncapped speeds.” | Not current plans | Three's current Complete-plan page advertises everyday speeds of up to 100Mbps. |
| “There is no way to get faster speeds.” | No | Three currently offers Full Speed through Lite+ and a £4 monthly add-on for eligible Pay Monthly customers. |
Why this matters for mobile customers
This is a useful reminder that changing one part of a mobile bundle can sometimes alter other parts of the contract. As networks create more complex tariffs containing streaming, roaming, insurance and speed tiers, the difference between an add-on cancellation and a plan migration becomes increasingly important.
The monetary value is also not always obvious. A customer might remove a streaming service to save money but then discover that restoring their previous data performance requires another monthly add-on.
Bundle changes may affect speed, roaming, entertainment and device benefits together.
An old uncapped tariff may be more valuable than it first appears if the replacement is restricted.
Judge the saving after accounting for any replacement Full Speed add-on or lost benefits.
Bottom line
Some older Three Complete customers should think twice before removing Paramount+ if the change also moves them onto a 100Mbps speed cap
The key issue is not that Three has suddenly imposed a brand-new cap on everybody. Three's current mainstream Pay Monthly tariffs already advertise everyday speeds of up to 100Mbps. The potential problem is for legacy customers who still have older uncapped terms and may lose them when changing their package.
Three's Paramount+ price notice adds a reason for customers to review the streaming part of their account, while the £4 Full Speed add-on gives customers on eligible newer plans a route back to unrestricted network speeds.
The safest one-sentence summary is: if you are an existing Three Complete customer with an older plan, check every term shown before removing Paramount+, because the change may involve migration to Three's newer 100Mbps-capped tariff rather than simply cancelling the streaming benefit.
Frequently asked questions
Does removing Paramount+ from Three automatically add a 100Mbps cap?
No. The report concerns some existing customers on older Complete-plan arrangements. The concern is that removing Paramount+ may require those customers to accept Three's newer airtime terms, which include a 100Mbps speed limit. Check the change summary for your own account before confirming.
Are Three's current Pay Monthly plans capped at 100Mbps?
Three currently says its standard Pay Monthly plans have everyday speeds of up to 100Mbps. Its current Lite, Value and Complete plan descriptions carry that limit, while Lite+ includes Full Speed.
Can I pay to remove Three's 100Mbps speed cap?
Three currently lists a Full Speed add-on for Pay Monthly customers at £4 per month. Check My3 or the Three app to see whether it is available on your specific plan.
How much will Paramount+ cost through Three?
Three says the chargeable Paramount+ Standard Monthly Plan will rise from £7.99 to £9.99 per month from 27 August 2026 for new and existing customers. Eligible Complete plans currently include Paramount+ as a plan benefit.
Is 100Mbps slow for 5G?
It is lower than the speeds a good 5G connection can sometimes deliver, but 100Mbps is still fast enough for most everyday phone use, including streaming and video calls. The difference is more noticeable for large downloads, tethering and people using mobile data as a broadband replacement.
How do I know whether my old Three plan is uncapped?
Check your contract documents, account information and any original plan terms. If the speed position is unclear, ask Three to confirm whether your existing tariff is subject to the current 100Mbps restriction before making any change.
Should I cancel Paramount+ if I do not use it?
If it is a separate chargeable add-on you no longer want, cancelling may save money. If it is included within an older Complete plan, first check whether removing it changes any other contract terms, particularly your mobile-data speed.
Does the £9.99 Paramount+ price apply to every Complete customer?
Do not assume so. Three currently says eligible Complete plans include the Paramount+ Standard Monthly Plan for the length of the plan. The £9.99 notice concerns the chargeable monthly subscription. Your own contract and account information should confirm how the change applies to you.

Accuracy note: the reported link between removing Paramount+ and accepting a 100Mbps cap concerns some existing legacy Complete-plan customers. Three's public pages confirm the current 100Mbps plan structure, Full Speed option and Paramount+ pricing, but they do not state that every Paramount+ cancellation triggers a speed-plan change. Customers should therefore rely on the contract-change information shown for their own account before confirming any modification.
