I bought it for the Internet at the dacha, inserted a SIM card and use it as a modem paired with a wi-fi router. For a long time there were no complaints in the work, however, when the temperature outside exceeded 30, tricks began. The device writes that the SIM card is not detected, but after a reboot everything returns to normal. In less hot weather, this was not observed. I have been using since May 2022.
