KC868-A2 SIM7600 with Tuya GPRS not work

[alexps70]

Установил прошивку 2.18
в интерфейсе показывает, то Tyua и GPRS - Connected
но в приложении на телефоне устройство Offline (никакие команды управления не проходят)
ди и на сайте https://eu.platform.tuya.com/ видно, что устройство отваливается спустя пять минут
