I feel bad for some of my customers that I was shipping 3g routers until mid-2018. Looks like a couple automakers were shipping 3g equipment in 2019. I think several platforms like Tank Links are also going to have a purge when cheap 3g goes dark.
I wish there were some super cheap sparse data plans that worked out in the middle of nowhere USA. Everything out there want 10K units for get good discounts.
