Hi @Kadanza,

How often does this error occur for you while you're using 2G?
Could you give us following info about testing device and connection:

• OS version
• device model - did you try it on another device models
• connection type - did the error happen just on 2G (not wifi, 3G...)
• does the error happen just on one mobile operator

We've made tests over 2G and didn't reproduce this error yet.

This is a caught exception and it doesn't affect library performance. API that failed tried to synchronize message delivery reports and other message operations which are all retried.
