Frequently asked questions

You can change your plan to get more allowance by going to My3 or using the Three app. If changing your plan doesn’t work out, let us know. We can always drop you back down to your base commitment. 

If you’ve joined us after 30 Jan 2023, you might be on a Three Your Way plan. If so, you won’t be able to change your existing plan. But the good news is you can always change your data tier by using the Three app.

If you’ve got a Device plan on Three Your Way and you change your plan, you'll need to continue paying off your Device plan until the outstanding balance is paid. You can settle your outstanding Device plan balance at any time via bank transfer, or by getting in touch. For more info, see our Device plan FAQs.

You can cancel an Add-on on My3 or on the Three app. If you have any trouble, get in touch.

If you're on Pay As You Go, you need to have enough credit to buy an Add-on. If you're a Pay Monthly customer, the cost of your Add-on will be taken from your monthly bill.

Pay Monthly customers can purchase multiple Add-ons, but each one can only be active once per billing cycle. For example, if you buy a data Add-on during one billing cycle, you won't be able to buy the same data Add-on again during the same billing period. However, you can buy multiple different Add-ons per billing cycle.

You can buy an Add-on in the Three app or on My3. No data? No problem. The Three app works even when you’ve run out.

How long an Add-on lasts depends on which you’ve chosen and what plan you’re on.

For Pay Monthly customers, all Add-ons except our Short-Term Boost and One Day Boost renew automatically until cancelled.

For Pay As You Go customers, Add-ons typically last for one month from the date of purchase. You can check the app for more details.

You can check which Add-ons you have, see which ones are available to you, and buy Add-ons on our app.

You also log in to My3 and select Allowance then Add-ons. The price you'll see for short-term Add-ons is a one-off cost until the end of the billing month. Long-term Add-ons have a monthly recurring cost.

No. So long as you have a data allowance, you can use your Personal Hotspot to share data with other devices. Learn more about Personal Hotspots.
