LB2120 APN profile

[lte_rtr]

I am trying to configure this modem as a backup for our network and one of the most important things is to update the apn profile.

using the mobile tabe and APN option, i add the APN details and click on save. it displays the message tht the profile successfully saved. but it does not show the profile, nor does it seem that it has taken effect?

any help is appreciated!

Checking in again. nobody, not even netgear's support people have an idea why a brand new device is misbehaving?
