When an enterprise prepares a batch message list, if it cannot distinguish between Android and Apple numbers, it will be difficult to formulate a sending strategy according to the device system.
The original number is not marked with the mobile operating system
Mixing Android and Apple numbers affects list grouping
Message content may not be suitable for all terminals
A large number of numbers need to be sorted manually before mass sending
Wrong channel assignment increases send failure rate
Lack of independent Android user number list
