International unlocked cell phones are those that are not tied to a specific service provider. This means that they can be used with any SIM card from any operator in any country in the world. These cell phones offer greater flexibility and freedom for the user, since they are not limited to a single provider or contract. ​In addition, international unlocked cell phones tend to be compatible with a wide range of frequencies and technologies, making them ideal for those who frequently travel abroad.
