Hi TK Liew / Peplink Team
Many thanks for replying.
I was envisaging a list where I add the MCC/MNC codes for the networks I want to be able to connect to one by one then maybe an option in cellular settings where the whitelist can be turned off and on. This way there would be no need to add all the networks on a drop down, for example, and you would not need to keep any lists up to date as new networks are formed. The router when in automatic network selection mode would then look at all the networks it can see and see if any are on the "allowed" list before it connects.
The manual carrier selection option that you currently have is great and does not need changing in any way. We find the scan facility much more useful than manually setting the network via MCC/MNC code which some other makes (e.g. Cradlepoint) employ.
Your UI is the best of the bunch by the way. We have exposure to most of your competitors and yours is head and shoulders above the rest. Automatic firmware update check doesn't work too well though if you are after feedback - I tend to have to do this manually.
