Question
What is a zero-byte session?
Why does my device open data sessions but not transmit any data?
Answer
A zero-byte session refers to a mobile data session established by a device without any payload (user) data being exchanged.
The session is technically live, but it does not serve any data transmission.
Both Upload and Download remain at
0 bytes
in such cases.
Cause
Zero-byte sessions are often the result of applications initiating mobile data sessions without following through with data transfer. This could be due to:
Firmware design that checks connectivity without actual data exchange.
Server endpoints failing to respond or accept data.
Application logic errors.
