3. Will RoamSave work with a home or hotel’s free Wi-Fi service?
A: Yes RoamSave basically works with any Wi-Fi connectivity, regardless of whether it is a free service provided by a hotel or a router in someone’s home (note: csl cannot guarantee RoamSave service performance nor voice call quality at every single Wi-Fi hotspot).

4. Why does the RoamSave icon disappear from the status bar?
A: This represents weak or no Wi-Fi connectivity. If this occurs, move to an area with better Wi-Fi coverage and remain there until you finish your call.

A: Yes.

7. When I am on a RoamSave call, will the call be disconnected if I leave Wi-Fi coverage?
A: Yes, the call will drop because the Wi-Fi connection will be lost and the RoamSave application will be disconnected. You are recommended to stay within the coverage area until you finish your call.

8. Will my RoamSave application be re-connected to Wi-Fi automatically when I return to an area with Wi-Fi coverage?
A: No. You will need to connect your RoamSave application to Wi-Fi manually (please refer to User Guide Q1). Until you reconnect RoamSave, you will be able to receive calls via regular voice service.

9. Why can’t I connect to RoamSave when my handset detects Wi-Fi?
A: The Wi-Fi signal only shows that you are within hotspot coverage, but you may need to login to the Wi-Fi network before proceeding to RoamSave (note: csl cannot guarantee RoamSave service performance nor call quality at every single Wi-Fi hotspot).

10. Why is RoamSave call quality better on a headset than when I hold the handset in my hand?
A: Some handsets are intelligent enough to turn off the screen automatically when it detects a human face in order to avoid buttons being touched by accident. However, the turn-off screen mode will also switch Wi-Fi connection to power save mode automatically, thereby making call quality unstable or even poor because of a weak connection.

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

11. Why can’t I use my Bluetooth headset with RoamSave?
A: RoamSave does not support a Bluetooth headset, but you can use an ordinary wired headset with RoamSave.

12. Why can’t I receive a call when my handset screen switches to standby mode (ie when the handset screen is off)?
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?
A: Please check whether the outgoing voice function of your account has been barred. You may want to contact the 24-hour csl Consumer Service Hotline 1000 for more details.

15. I am a Pocket Wi-Fi user, so can I use RoamSave?
A: Yes

16. I am a 1SIM2Number subscriber, so can I use RoamSave?
A: Yes. Please note the following:
Caller display will show your Hong Kong mobile number only when you make an outgoing call with the RoamSave application, even if you are inside China Unicom’s network coverage.
You are required to pay an “Outside Region Connection Fee” of $1/minute to receive calls via the secondary number (ie China Unicom mobile number) in addition to the standard RoamSave service charge, and the charge is applicable to all destinations.

17. Why I can make outgoing RoamSave voice calls but can't make outgoing RoamSave video calls?
A: Please check whether your RoamSave app version supports to make RoamSave video call (updated version: 4.2.0). You may want to contact the 24-hour csl Consumer Service Hotline 1000 for more details.
