Genius, what service charge will the phone watch charge?

Wonderful wisdom books, calls, traffic, short messages, etc. Will be deducted.

Watches mainly need traffic when chatting and positioning. According to the calculation of sending and receiving 100 times of voice and positioning 100 times a day, the monthly traffic consumption is about 30M, and the traffic consumption is very small.

SIM card must enable caller ID, SMS and traffic to ensure the normal use of watch functions. If it is not enabled, caller ID may not be enabled, the watch cannot recognize the number, and family members who are already in the contact list will be rejected. If you don't open SMS, there will be problems such as being unable to activate and checking the phone bill.
