Common Travel Data Mistakes & How to Avoid Them

Most travel internet problems aren't bad luck — they're the result of mistakes that can be avoided with advance planning. Here are the six most common mistakes and how to sidestep them.

Mistake 1: Installing the eSIM at the airport instead of before

What happens: you land at the airport and try to install the eSIM — you may hit network issues or APN settings that take time to sort out. Fix: install the eSIM on Wi-Fi a day before travel and confirm it's working.

Mistake 2: Buying a data plan smaller than you need

What happens: your plan runs out mid-trip and you're forced to buy another at a higher price or go without internet. Fix: estimate your daily consumption (see "How much data do you need") and add 20% as a buffer on top of your estimate.

Mistake 3: Forgetting to activate the eSIM data line in Settings

What happens: the eSIM is installed but the phone is still using your old SIM for data. Fix: right after installing, go to Settings and confirm the eSIM is set as the data source and that Data Roaming is enabled on it.

Mistake 4: Watching video in high quality on mobile data

What happens: YouTube or Netflix in HD quality burns through gigabytes in hours. Fix: download what you want to watch on hotel Wi-Fi then watch it offline. Use mobile data only for browsing and communication.

Mistake 5: Not downloading offline maps

What happens: Google Maps uses data continuously and can let you down in areas with weak coverage. Fix: before travelling, open Google Maps, search for your city, and tap the offline download button.

Mistake 6: Relying entirely on roaming

What happens: the traveller turns on roaming and browses freely — the end-of-month bill is a shocking and painful surprise. Fix: use an eSIM for data at a pre-fixed cost, and keep roaming on only for necessary calls from your Saudi number.
