If I have a Huawei cell phone, I have read that it must be connected to Bluetooth. My question is only at work I usually have no network. Does it do what or is it enough, only Bluetooth and network do I need none? Be happy about any answer.
You set up the band, and whenever you want to synchronize the data you turn on Bluetooth an internet is not necessary.

The tape does not need internet or a permanent connection to the cell phone to record your steps.
Connection is only necessary to synchronize your tape with the app, or if you want to receive notifications from your phone on the tape.
