  • From perspective of a vehicle running. Which has more confiability/stability in sending data? Or why is better one than other? Thanks. Feb 5, 2019 at 18:24

    If it's for a car, maybe you have in mind "location of the car". In that case notice SIM800 dont have GPS. The location a SIM800 can give is the location of tower cell which can be far from the device. For sending data, saving them and so on I suggest to have a look at hologram.io SIM card. I use them for IoT project and that's pretty nice.

  • Hi Peter, I understand your comment about the GPS. Actualy in my project use a GPS module of UBLOX, the NEO-6M. Also thanks you for share me your hologram technology, it looks very interesting and useful. Best regards. Feb 6, 2019 at 22:01

SIM900 is older type. SIM800L has FM build it and it uses same AT cmds as SIM900. Also, they are in same quadband. I guess both will work just fine.
