Hello Manoj,
In the description of the HIROH-phone is talk of a software-based switch to easily turn off all your radio signals, Wi-Fi, Bluetooth and NFC.
I think this is the so called flightmode? Is it possible to program this switch to get a Dumbphone. Then we can make a phonecall or sent a sms message?
Thanks in advange,
Huib
Will have to check with the team and get back. You can read some response from the HIROH CTO here and here. The details on the Murena site as available with us are visible here.
