Practical notes on staying connected while traveling.
eSIM vs. roaming: what actually saves you money
Your home carrier's roaming rates are almost always the most expensive way to get data abroad — often several dollars per MB. A local prepaid eSIM for your destination is usually a fraction of the cost for the same data, since you're buying at local rates instead of a roaming markup. The other common option, a physical local SIM, saves money too but means finding a shop, having ID ready, and losing your home number while it's in the tray. An eSIM gets you the local rate without any of that.
Regional vs. country-specific plans: which to pick
If you're visiting one country, a country-specific plan is almost always cheaper per GB than a regional one. Regional or global plans make sense when your trip actually crosses borders — a two-week trip through three European countries is one eSIM instead of three, and the price difference is usually smaller than the hassle of managing multiple plans.
Fixed data vs. daily allowance: reading the fine print
Plans come in two shapes: a fixed total bucket (e.g. "5GB, valid 30 days", usable whenever until it runs out or expires) and a daily allowance (e.g. "1GB/day", where each day resets — unused data that day doesn't roll over). Daily plans suit steady, predictable use; a fixed bucket suits uneven use, like a heavy first day of maps and photos followed by lighter days.
