What purpose are from that commands, support from quectel never mention them in my cases.
MBN - those are files with firmware programming...
Do you read main thread about EP06* and my #10 post?
Quectel EP06-E and wAP R ac (RBwAPGR-5HacD2HnD) - MikroTik

Whats worked lately with visible(verizon) and ATT is:
-Program the correct APN into the connection profile manager
-Remove all of the AT+CGDCONT entries, including AT+CGDCONT=1, via AT-Terminal window.
-Power cycle the router
Router will come up, program the correct APN and eventually connect, and has been persisting through multiple reboots.
Seems that when I change SIMS, the default values of AT+CGDCONT? change, I assume due to the type of sim card. My testing so far shows that if there is any other entry than the APN we're trying to connect to in AT+CGDCONT causes some kind of issue.
Still somewhat of a mystery, but they modem has worked for two days and through several reboots. I'm still not sure I trust them though lol.
You are correct when you switch SIM or when Quectel modem detects a different sim that it recognizes. It will switch to that carrier's MBN file (in this case it's Verizon) which gives you all the APNs that you see when doing AT+CGDCONT? When it doesn't recognize the SIM, it will switch to the default generic MBN file which is why it works on carrier like T-Mobile/SimpleMobile without encountering the connection problems.
What you want to do is issue the following commands:
CODE: SELECT ALL
AT+QMBNCFG="AutoSel",0 (stop Autoselect config on sim detection)
AT+QMBNCFG="Deactivate" (disable MBN config)
AT+CFUN=1,1 (reboot the modem)
That should let you use the APN you set in your router.
If you have problem connecting without using the MBN config, select the generic config by typing:
CODE: SELECT ALL
AT+QMBNCFG="List"
AT+QMBNCFG="Select","The_Generic_Config_Listed"
AT+CFUN=1,1
Also, if your modem doesn't use band 66 for CA for some reason. Force it by disabling band 4. For me,
CODE: SELECT ALL
AT+QCFG="band" yields AT+QCFG="band",0,2000001003300185a,1
