About Us
TravelSIM was built to solve a real problem: figuring out which SIM card to buy before you land in a new country. We research local providers, compare prepaid plans, and document where to buy, so you can get connected without overpaying or wasting time.
Buying a SIM card abroad should be straightforward. But every country has different carriers, registration requirements, pricing structures, and purchase locations. Most of this information is scattered across forum posts, outdated blog articles, and carrier websites that are only available in the local language.
We built TravelSIM to consolidate this information into a single, reliable resource. Each country guide is structured consistently so you can quickly find what matters: which provider to choose, how much it costs, where to buy it, and what documents you need to activate it.
Our research process is designed to produce accurate, current information that travelers can rely on. Here is how we build and maintain each country guide.
We review official carrier websites, tourist SIM pages, and prepaid plan catalogs for each country. Plans are documented with exact pricing, data allocations, validity periods, and included call minutes.
SIM registration laws change frequently. We cross-reference government telecom authority publications and recent traveler reports to ensure our activation requirements are current.
We incorporate feedback from travelers who have recently purchased SIM cards in each country. This helps us verify purchase locations, confirm pricing accuracy, and flag any recent changes.
Provider coverage ratings are based on published network maps, third-party speed test data, and reported coverage in rural and suburban areas. We rate each carrier on a 5-point scale.
SIM card pricing and plans change over time. We review and update our most popular country guides on a regular cycle to keep pricing and plan details current.
For countries where eSIM is available, we include a comparison with local SIM options so travelers can make an informed choice between physical SIM and eSIM solutions.
