KuWfi LTE router APN setup

[take]

It seems that my post has been deleted, so I’m posting it again. If I violated any rules, please let me know.

I’m trying to use data communication by inserting a PM SIM card into the KuWfi LTE router (CPE812), but it seems I’m unable to configure the APN settings properly, and I can’t connect. As shown in the attached photo, I have entered "sp.mb.com" for the APN, but what other settings are required?
I don’t know how to add other information other than APN section to the attached KuWfi router web interface because the fields don’t match with PM APN information, like MMSC.

What I tied based on the comments I got from the first post;
1) set "Auto select 3G/4G ISP" but it did not work.
2) set "primary DNS server" to "8.8.8.8" and "8.8.1.1" but both did not work.

If you have any other idea, please let me know.

Thank you all for your many suggestions. I'm currently communicating with KuWfi support, so I'll provide an update once the cause of the issue is identified.

Hi, hTideGnow the router is bought from Amazon.

hi @take where you got it from? Second hand via private sell or via proper shop? 

try with another carrier sim card and check if the router works at all.

not sure if it is connected, there is no IP address in WAN , so it meant either connected but unable to get an IP from PM or it wasn't connected at all

Hi slusagm, I believe the router is connected but not configured to transfer data. Attached status page.

Hi hTideGnow, I tried Auto Select but it did not work. No public mobile in the pull down.

Thanks

I remember your post.  I think you said putting DNS does not resolve your problem?  But the DNS there is neeeded

how about authentication set to Auto?  and that CDMA line, I don't like CDMA 1x Only, other choices?

and does it has an interface to show if it connects or not? we need to see if it connects and just some settings not right or not connect at all

hi @take did you try check mark the boxAuto select 3G/4G ISP? Also, instead of "User defined" any other option in that pull down?
