Travel eSIMs are useful, but they still leave you guessing. You pick a country, choose a data pack, hope it lasts, and then lose whatever is left when the plan expires. If your trip has more than one country, the whole process starts again. Roamless caught my attention because it tries to remove that cycle.
Instead of making you buy a new eSIM or country plan for every trip, Roamless gives you a single global eSIM and a single balance. You add credits, use data where Roamless is supported, and keep the leftover balance for later. That makes it especially useful for people who travel a few times a year and hate wasting unused data.
