Travelling to Portugal from the UK? One of the biggest hidden travel costs is mobile data roaming.
Many UK networks charge £2–£6 per day to use your phone abroad. Over a 10 day holiday that can easily add up to £20–£60.
A travel eSIM is a much cheaper and easier alternative. Instead of paying roaming fees, you can install a data plan before you fly and land in Portugal already connected.
