Hi, I am using many rut240 for teleservice of industrial applications. When not in use for their application and are just powered on, there is a dailly traffic of 2-3MB, even when no other device is connected. So this is 60-90MB per month. SIM CDR traffic is usually from 400KB to 1500KB per 6 hours. The RMS is disabled. However, there is a dynamic dns service (NO-IP). It is set to run every 10 days with force renew every 20days. The IPs are public and static.
Is it possible to reduce this data traffic?
