What is travSIM?
travSIM is a provider of travel SIM cards and eSIMs that allows you to have a mobile plan dedicated to international use without changing your main subscription. eSIM profiles are downloaded onto the compatible smartphone’s embedded chip, while traditional SIM cards are physically delivered before departure. Once activated, the SIM card or eSIM uses partner local networks to provide data and, depending on the offers, calls and SMS. The catalog mainly includes local plans by country, notably for the United States, Canada, Mexico, South Africa, Europe, and other destinations, with volumes ranging from 1GB to unlimited offers for durations of 1 to 90 days. Orders are placed online, payment is made by card or e-wallet, then the user follows instructions received by email to install and activate their SIM or eSIM before traveling.
