You can edit the turn-off screen mode using the RoamSave application:
Go to “More” and tick “Keep Screen On”.

A: Some handsets may turn off the Wi-Fi connection in standby mode, thereby disconnecting RoamSave.
You can edit the standby mode in your handset’s settings listed as below:
Settings > Applications > Development > Stay awake
(note: You need to connect your handset with a power cord)

13. Why can’t I receive incoming calls when I can make outgoing RoamSave calls?
A: Please check that you have enabled an unconditional call-forwarding function (**21*). If you have, then please disable it (##21#) before re-starting the RoamSave application by pressing the on/off button once.

14. Why can’t I make outgoing RoamSave calls when I can receive incoming RoamSave calls?
