Guys, I have a problem with my ASUS AC88U router while configuring the zte USB modem.

The router firmware shows that the usb is recognized as a modem and I try to configure the dial up automatically/manually (login and apn details), both doesn’t seems to be correct.

The USB modem is blinking blue, I guess sim is activated. Any lead? My current fiber modem ™ is fried and waiting for TM to come. Maxis told me it will be 29th May (reported beginning of May)
