I mean, #Motorola at least made the #Iridium9500 & #Iridium9505 compatible with a #CellularNetwork by offering a " #CellularCasette " adaptor that could do #GSM900 [and some could even do garbage like #AMPS & #CDMA!] so that #Iridium users could roam on #GSM inside #Cities and get #Iridium where no #CellNetwork reached them!

Using A '90s Satellite Phone On The Iridium Network

@triptych Would love to, but @BNetzA says nope.

- As in: 'You cannot use any non-approved transcievers' and 'The primary users of said Band [ #GSM900 ] have every right to the exclusive frequency allocation they paid for.'

And as cool as it sounds, I'd rather not risk €50k+ in fines if not jailtime for #SpectrumViolation|s...

- Maybe someone will make a #LoRa / #Meshtastic version that uses 27/40/433/868MHz ?

I boosted your post tho, cuz the #Cybiko is still cool.

Hey! I'm so excited, just disassembled an old Siemens P1 car phone. It's a GSM900 phone built with discrete components!
And it has 5W max RF power!

Take off Your shoes, we're gonna look inside the device: sdr.li/post/longrangemobilephone/
