Why can't Mi Tu Telephone Watch get through to telecom users?

Does not support telecom SMS and phone calls.

The SIM card of the watch is plug-in, and users need to buy Nano-SIM cards (Mobile, Unicom, Xiaomi Ren Woxing, etc.). ) on your own. At present, the telecom version is not supported to send and receive text messages and calls.

It is suggested that parents who support the mobile/Unicom 4G SIM card open a supplementary card as the calling card of the watch. Open one less MasterCard and save next month's rent. If you support the secondary card service, please consult your local operator.

If the watch is used continuously for a certain period of time, and the plant identification is more than 15 minutes, it will be forbidden to use the above functions, so as to prevent children from eye fatigue caused by playing the watch for a long time and effectively prevent the watch from consuming too much electricity due to continuous use.
