Use of phone as APP device only - no phone service required

A

AC Question

I have a ZEPP golf analyzer which I now want to use with a smart phone rather than an iPad. There is a ZEPP device on my golf glove that talks via Bluetooth. It also gathers 2 more stats if the phone is in my front right pocket when I swing.

Anyway, I don't want / need any phone service. I imagine I can use a WiFi connection to talk to the ZEPP server which gathers and reports on data.

How can this be done - I don't need or want any 3G or 4G phone service (so I don't need a phone number).

Thanks. Tom
