Troubleshoot SWWAN "SM activation error",136 on ELS61-E | Telit Cinterion IoT Developer Community

August 29, 2023 - 7:35am, 394 views

Hello, I have a ELS61 based routed and I managed to use it on MBIM mode. However, I would want to try it on ECM with AT^SWWAN=1,2 but it returns a +CEER: "SM activation error",136,"Regular PDP context deactivation" error. However, I am able to ping with AT^SISX="Ping"
