About our Boosts

Our Boosts last for (or refresh every) 30 days and can be purchased out of the credit you currently have on your phone. If you do not have enough credit on your phone to apply a Boost you will need to pay for the Boost in full at the time of purchase.

Boosts are valid whist you are in the UK or traveling within the EU/EEA (subject to the fair use data and roaming policies). Boosts cannot be used when traveling outside the UK and EU.

For your convenience you can add a one-off Boost, or you can add a recurring Boost. With a recurring Boost we will add the selected Boost to your SIM/account every 30 days. If you have insufficient credit, we will automatically top-up your phone from your stored payment details.

The Calls+Text Boost, and data Boosts that include unlimited UK calls and texts, includes all calls to 01, 02, 03 & 07 UK numbers. If all the data in a data Boost is consumed, simply add another, or pay our standard rate of 1p a MB for any excess data you use.

Excess data - If your 30-day data usage exceeds the size of the Boost(s) applied, any excess data will be charged at our standard rate of 1p/MB and deducted from your credit balance. Alternatively, you can buy an additional data Boost from our website. There is a cap of 14GB when using the data in the EU with roam-like-at-home. Any additional data used, over 14GB, will be charged at the standard rate of 1p a MB.

The "Order SIM" button for "Unlimited UK calls and texts", "1GB" and "4GB", will take you to the order page to order a standard £10 SIM. Once this has arrived and you have activated it, you can add the Boost of your choice from the £10 credit on the SIM.

* If ordering a 10GB, 25GB, 50GB, 100GB or 200GB Boost from here then the Boost is automatically applied when the SIM is activated and it set to auto-recurring.
