What is a Spend Cap?

A Spend Cap lets you limit your spending on things not included in your monthly plan. This includes calls, texts and data. But things like Add-ons, insurance and using Three Pay aren’t included.

How to set a monthly Spend Cap

Choose the max you’re willing to pay on top of your plan and that’s it. You can set your cap to £0 if you want, or to anything between £10 and £100 – in £10 increments. You can also choose to switch the cap off completely.

It’s easy to set this up by logging onto My3 or the Three app. Here’s how:

Three app steps

  1. Open the Three app
  2. Go to the Bills tab
  3. Select Set a spend cap

My3 steps

  1. Log into My3
  2. Open the Your Account menu
  3. Select Allowance and price plan
  4. Then select Control your spending

If you have any problems setting up your Spend Cap, contact us. You can also visit your local Three store for help.

Go Roam:

From 23 May 2022, Pay Monthly customers who joined or upgraded their plan on or after 1 October 2021, will incur a daily roaming charge to unlock their UK allowances for 24 hours in Go Roam destinations. The daily roaming charge is £2 in Go Roam in Europe destinations and £5 in Go Roam Around the World destinations. The daily roaming charge is triggered as soon as a customer uses any of their plan allowances in a Go Roam destination. View here for further information.

Republic of Ireland and the Isle of Man are exempt from the daily roaming charge. Fair use policies apply.

The charge counts towards your Spend Cap, so if that’s set at zero, you won’t be able to use your UK allowances in Go Roam destinations.

If your Pay Monthly contract started before 1 October 2021 there’s no daily charge in Go Roam destinations. This means you can use Go Roam no matter which Spend Cap you choose.
