WP7702 with LTE-enabled SIM issues

Cloud & Connectivity

Hi

When I use WP7702 with an LTE and GSM-enabled SIM but not LTE-M1/LTE-NB enabled, the WP module does not use the GSM fallback. And even if I get it to use the GSM fallback it does not maintain a stable connection.

The only way for me to get a stable connection is by disabling LTE RAT completely using at+ksrat=1.

Is this a known issue, any known workarounds or fixes that doesn’t involve completely disabling LTE?

Did you get any further with this issue? I seem to have the same behavior.
