I'm attempting a few projects, including my rover, that will require cellphone voice access via computer audio. I know the DroneCell exists for everyone who's not on an AT&T/Bell/Telus style network, but for those of us who are stuck on UMTS/HSPA 850/1900, has anyone else come across an easy-to-find replacement?
I've discovered a few USB dongles that theoretically work, or are known to work, but they are all so old that they've become quite hard to find. The one with the most information I can find is an Huawei E156. USB wouldn't be optimal for the drone tho, something like dronecell would, and can also be adapted for my usb uses I think.
Thanks for any information!
