What we write about

Most of what gets published here falls into three buckets: setup and troubleshooting walkthroughs for specific handsets, data-planning guides that translate a trip itinerary into a realistic gigabyte figure, and country notes covering where coverage is reliable and where it thins out.

The recurring theme is that connectivity problems abroad are rarely about the plan. They are about a carrier-locked handset, a roaming toggle left off, or mobile data still pointed at the home SIM — so the guides spend more time on settings screens than on marketing.

Working out how much data you actually need

Maps, messaging and the occasional web page are light: a week of that typically lands somewhere around one to three gigabytes. Streaming video, video calls and uploading photos are what move the number, and tethering a laptop moves it fastest of all.

Buying slightly short and topping up mid-trip usually costs less than buying a large bundle you do not finish, because unused data does not roll over once a plan's validity expires.
