Fona

Adafruit sells breakout boards called FONA

2G is going away next year so that pretty much leaves the first one. I ordered one to (try to) get the free additional line from Ting that is on offer. I hope it gets here in time.

• FONA 3G has a GPS receiver, about $80
• FONA 808 2G + GPS, $50
• FONA 808, shield format $50
• FONA MINI $45 2G only, FM radio

These are all accessory boards, meaning you probably want to hook it up to a controller like an Arduino for instance.

They sell the Particle Electron 3G board too, in fact I have one of those, but it's NOT an accessory board and I am not excited to learn how to program it right now. Maybe later.
