I can’t send email through Ewon flexy with cellular modem. We previously had a hardwired WAN connections for internet access and cellular modem as fallback. We now had to remove the Harwired connection and cellular still in fallback mode. Can we keep this In fallback mode permanently, since I can no longer use a hardwired connection. Or should I change the cell modem as primary connection? Is there a difference? Thanks in advance.
