We recommend a Level of minimum 18 for a good communication.
Under 18, the communication will work but with some errors, so some packets will be repeated and the overall throughput will decrease.

A signal level of 99 is displayed, when eWON did not yet receive the signal level information from it's modem.

Note concerning the signal level on UMTS/HSUPA networks: 
HSDPA network emits with a lower power, so it is normal to have a lower signal level indicated on the eWON. On UMTS or HSUPA networks even a low signal level of 5 will work.
