I am using a WP7702 module which I try to connect to an LTE-M1 network. The module is fully compliant with 3GPP Release 13 thus I [expect](https://en.wikipedia.org/wiki/LTE-M) to see a device receive bandwidth of 1.4MHz, how-ever when looking at `AT!GSTATUS?` is shows `LTE bw: 10 MHz`, which I do believe is not LTE-M1, but LTE-WB instead.
I used `ATSELCIOT=6` to ensure `LTE-WB` is disabled, but have no way of knowing if this is actually enforced. I have not found a status command which give clues in the actual LTE operating mode and Cellular IoT (CIOT) operating mode in use.

Does anybody know how-to reveal the LTE operating mode and Cellular IoT (CIOT) operating mode which is currently in use?

you can disable CAT-M1 network in AT!SELCIOT and see what happens.
Here is my module registered with CAT M1 network:

Thanks for the suggestion, I have disabled CAT-M1 `AT!SELCIOT=1` and this results in no connection after waiting for 10 minutes. So yes, the connection is LTE-M1 based.
I am still confused on the reported bandwidth how-ever `LTE bw: 5 MHz`, especially since `eMTC LTE Cat M1 (3GPP Release 13)` seems to support a bandwidth of 1.4 MHz exclusively, where-as `LC-LTE/MTCe LTE Cat 0 (3GPP Release 12)` seems to support a bandwidth range of 1.4–20 MHz.
How should I read this value?

The product technical specification says it supports 3GPP LTE release 13:
