I came across this in the play store, not sure if it has the software necessary to enable Bluetooth calling or text messaging from the watch to a phone.
I haven’t been able to root my watch.
Install both apps, one to write the stack (requires root) the other to enable functionality.
Bluetooth SIM access install
Bluetooth SIM access profile
SIM access profile (SAP) allows a phone to use the SIM of another phone via Bluetooth. This is mainly used by car phones which can use the SIM of your mobile phone. Unfortunately it doesn’t help us to get BT calling on our smartwatches.
My car radio can Bluetooth dial contacts from my phone… Even send texts…
It can’t be that difficult in my opinion.
Actually it’s not that easy.
Phone to phone is completely different to pairing your car or headset.
There is a thread about it at the top of this forum.
