How to choose a mobile operator?

Question

Computer networks

Hello, advise which mobile operator I should choose for the so-called "Internet of Things". I am engaged in the development of electronic devices that work autonomously for up to a year, and therefore the devices must turn on at certain intervals, receive and transmit information and turn off again. One unpleasant thing turned out, in megacities, such as Moscow, St. Petersburg, everything works fine. But in small towns: Tver, Ulyanovsk (and indeed 90% of the Volga region) during the day the connection to the Internet is very bad. The network in 80% responds with error 600 (network error). As I think, this is due to the fact that in such cities the reference stations (towers) have a small number of GPRS channels.

Answer 1

enter into a corporate service agreement with the operator with guaranteed slots and your own APN
