F.A.Q.s
Is a Lipo Battery required? Can I run the FONA off of a power supply or just the microUSB port?
I really want to run my FONA without a Lipoly battery!
Ahh! My FONA was working fine then I sent it some command and its not working right anymore?
I'm using FONA as a voice caller and the other person can't hear me!
My FONA doesn't work with Arduino Due/ADK/101/Galileo/STM32....
Can I charge the battery and use FONA at the same time?
My FONA won't turn on/respond! Or it acts flakey and auto-shuts off sometimes!
FONA 800/808 requires a 2G SIM, does it work with a dual 2G-3G SIM?
Are you sure I can't use ATT for 2G service? I'm in a T-Mobile cold spot
How long can FONA last on my battery?
How do I set the Real Time Clock on the FONA SIM?
I'm using a FONA 808 and the GPS commands aren't working
How do I switch between SMS storage on SIM and in internal FLASH?
I'm trying to reset the FONA with my microcontroller/computer and pulling the RESET pin low via a GPIO isnt
working?
