Drimsim is the first universal SIM card and free app for travelers. Drimsim is a real SIM card. It’s a plastic card with a chip, just like any other, which you can insert into your phone, tablet, or router. The difference is that it is not tied to an operator. Once your plane lands in a new country, Drimsim is immediately ready to work. Drimsim operates in 229 countries, provides stable communication, a fast Internet connection, and prices similar to those of local operators.
