Flexible rental periods are available for both short term and long term use. Travelers can choose a shorter plan or a plan over ninety days. Plans can be extended online when travel schedules change.

A reminder email arrives a few days before the return date, and an email with a tracking number is sent when the package leaves.
Will a SIM card work in every phone?+
