What happens when I hit my spend cap?

When you reach your spend cap, your network will block any further chargeable services until your next billing cycle. You can still use your included allowance (calls, texts, data within your plan) and make emergency calls. You can increase or remove the cap at any time through your network account.

What Is a Spend Cap on a Mobile Phone?

Q: What is a spend cap on a mobile phone?

A spend cap is a monthly limit on extra charges that go beyond your included plan allowance. It covers things like out-of-bundle calls, premium numbers, international calls and roaming charges. Your standard monthly plan cost is not affected by the spend cap.

What Is a Spend Cap?

A spend cap is a monthly limit you set on your mobile account to control extra charges that go beyond your included plan allowance. Think of it as a safety net: your normal monthly plan cost stays the same, but any additional usage that would generate extra charges is capped at the amount you choose.

If you set a spend cap of £10, the most you can ever be charged on top of your plan is £10 per billing cycle. Once you hit that limit, chargeable services are blocked until your next bill date.

What Does a Spend Cap Cover?

Spend caps apply to charges that sit outside your monthly plan allowance. These typically include:

Out-of-bundle calls and texts (once your included minutes or texts run out)
Out-of-bundle mobile data usage
Calls to premium-rate and directory enquiry numbers
International calls and texts
Roaming charges outside any included roaming allowance
MMS picture messages (on most networks)

What a Spend Cap Does NOT Cover

Your monthly plan cost is always charged regardless of your spend cap. The cap only applies to extras. The following are not affected:

Your standard monthly plan fee
Device instalment payments (if on a handset contract)
One-off charges such as late payment fees
Third-party subscriptions billed through your account (charity donations, app purchases)

Why Do Spend Caps Exist?

Since 2018, Ofcom has required all UK mobile networks to offer spend caps to customers. This regulation was introduced to tackle bill shock—the unpleasant surprise of receiving a mobile bill far higher than expected. Networks must let you set a cap at the point of sale and allow you to change it at any time.

How Spend Caps Help Businesses

For business mobile accounts, spend caps are one of the most effective cost-control tools available:

Predictable costs: Set a cap across your fleet and know your maximum monthly spend in advance.
Prevent misuse: Stop employees accidentally (or deliberately) running up charges on premium numbers or international calls.
Roaming protection: Particularly valuable for staff who travel, where a single day of uncapped data roaming can cost hundreds of pounds.
Budget compliance: Align mobile costs with departmental budgets without constant monitoring.
