Way late response. Was checking the forum about any issues from batch v3.0.
From pricier logger/DAQ setups, i’ve seen Raven cell modems from Sierra Wireless (with NexSens data loggers and NI cRio data acquisition the Raven modems). Not sure if folks have combined the modems with any Arduino boards.
Board-wise, I know of the FONA board from Adafruit: https://www.adafruit.com/products/3147
I also ran across Skywire (distributed through digikey): http://www.digikey.com/en/product-highlight/n/nimbelink/skywire-lte-cat1-modem
Note, no experience using either breakout boards.
If my XBee radios + Mayfly can’t punch through the elevation gradient and slight tree interference, I may end up going with a Campbell CR300 logger + Raven Modem (assuming boss has the cash). Not sure if I was of much help, ‘luck with your project! -h
