About Signal Atlas
Signal Atlas is a small, independent website that helps travelers understand and compare travel eSIMs. It is run by one independent creator who works behind the scenes; we keep the focus on the information rather than on a personality.
What we do
- Read providers' official plan pages, help centers and terms, and summarize them in our own words.
- Organize those facts into comparisons by destination, trip length and data needs.
- Write step-by-step setup guides based on Apple's, Google's and providers' official instructions.
What we don't do
- We don't claim to have personally tested every plan, and we don't publish speed tests, star ratings or "hands-on" reviews unless we actually performed them. We will say so clearly if we ever do.
- We don't invent experts, credentials, testimonials or user reviews.
- We don't sell eSIMs or handle your orders. You buy directly from the provider.
Accuracy and updates
Every guide shows a "Last checked" date and links to its sources. Travel eSIM prices change frequently, so always confirm the final price at checkout. If you spot an error, please tell us and we'll correct it.
