Both deals include unlimited UK calls and texts, and 20GB of the data allowance can be used while roaming in the EU and other selected destinations.

Giffgaff is also upping the amount of data on its £8 goodybag from 2GB to 3GB. This deal also includes unlimited UK calls and texts.

To purchase any golden goodybag, non-members need to buy and activate a SIM, select their chosen golden goodybag and set the purchase to recurring whilst ensuring that they have saved a valid card payment method.

Existing Giffgaff members need to log onto their account, select their chosen golden goodybag and set the purchase to recurring whilst ensuring they have saved a valid card payment method.

Once the above is completed and the golden goodybag is activated, customers who want to have 5G access can apply for a SIM swap for a new 5G-ready SIM to be delivered within one to two working days.

Once it arrives, all customers need to do is insert the 5G-ready SIM into a 5G-compatible phone and if required, enable 5G in their phone settings and do a software update.

Giffgaff customers can turn off the recurring payment option at any point after purchase. But if they want to re-purchase a golden goodybag, they need to go back through the new journey process by saving a valid card payment method and setting payment to recurring.

Those who swapped to the 5G SIM can also opt to switch back to 4G by either disabling 5G in their phone settings if available on their device, or requesting a 4G SIM and doing a SIM swap.
