Travel guides
Mobile data abroad, explained without the sales pitch: roaming rules, local SIMs and eSIMs.
How it works
- How to install a travel eSIM, step by step Step-by-step guide to installing a data eSIM before a trip: iPhone, Samsung Galaxy and Google Pixel, which settings to switch on, and what to do if you have no internet after landing.
- One eSIM for all of Europe, or one per country? Travelling through several European countries? When a single Europe eSIM beats buying one per country, what is and is not covered, and how much data you need. From 6,90 €.
- Your eSIM is installed and you still have no internet Your eSIM is installed, the phone says no service and you have just landed. The cause is nearly always one switch. Four checks, in the order that solves it.
- Two lines in one phone: which one uses data and which one calls Keep your number and bank codes on your usual SIM, put the data on the travel eSIM, and switch off the settings that quietly send you back to the pricey line.
- No, a data eSIM does not take away your number or your WhatsApp A data eSIM never touches your number. Why WhatsApp, Telegram and iMessage keep working, what the eSIM does not do, and how to still get your bank code.
- Sharing your eSIM data with a laptop or a tablet Yes, you can tether an eSIM. Why a laptop burns data far faster than a phone, what to switch off first, and how to pick a pack size when the laptop travels too.
- Before you fly: the eSIM checklist, in the order you do it The checklist in the order you do it: check the phone, buy, install at home on wifi, get the settings ready, and what to do when you land. From 6,90 €.
- How much data do I need for my trip? Work out the GB a trip needs: days times daily use, video on top, laptop on top. With examples by trip type and what to do if you fall short. From 6,90 €.
