@Pjpkp You purchase the roam abroad pass so you can use your allowance call/texts and up to 50Gb per month m. This will cost you £25 and it’s a 30 day add on that you need to stop when your back in the UK or you’ll keep being charged for it. You also need to make sure roaming is enabled on your account by texting ROAMING to 150. By enabling roaming you will connect to a roaming network. ( add ons don’t enable roaming).
