Professional byte-based subscription plans offer six levels of service. Unlike Professional Flex and consumer plans, byte-based plans are based on the total number of bytes used instead of a specific number of messages or tracking points. Byte-based plans allow for quicker tracking intervals (such as 30 seconds) than other plan types which offer tracking intervals starting at two minutes. Byte-based plans also offer the Team Tracking feature, which offers team tracking and messaging functions without cellular or Wi‑Fi^® connections.
