Just spotted this on Indiegogo:
https://www.indiegogo.com/projects/celtrix-...ce/x/13629384#/Would add phone functionality to a WiFi only Gemini. Could also allow a single SIM card to be shared amongst different devices, e.g. Gemini, other Android phones or tablets.
It isn't easy to swap the SIM card from the Gemini when you want to use a smaller phone for a day, so this would be an easy way to swap between using different devices, but have them all attached to the same phone number. I know that is what eSIM is for, but not many devices come with an eSIM and the only devices currently supported here in Australia are Apple watches.
