An anti radiation company had recommended that a USB 3G dongle be connected to the laptop using a USB cable. Initially it was working fine, now it is giving an error 633 and not connecting to the internet. Does anyone know how to bypass the problem?

Also you can restart your devices and attempt connecting again. There is a full guide linked https://www.thekonsulthub.com/how-to-solve-error-633-modem-or-other-connecting-device-already-in-use/
