Question
When should I turn on data for 8x8 Work for Mobile?
Applies To
Answer
8x8 Work for Mobile offers the ability for users to use
Wi-Fi or Cellular Data for voice calls and meetings. Cellular Data
operates differently depending on the platform and should be turned on or off
depending on how the user wants their call routed.
Android
Cellular Data On
If cellular data is on and the call is connected through
Wi-Fi, when the user leaves the Wi-Fi coverage area, the call will
automatically switch to cellular data.
Cellular Data Off
If cellular data is off and the call is connected
through Wi-Fi, when the user leaves the Wi-Fi coverage area, the call will
automatically drop.
iOS
Cellular Data On
If there is an active cellular data connection and the user
makes a call when connected to Wi-Fi and then moves out of the Wi-Fi coverage
area, the call is automatically handed out to the Cellular Data network without
any user intervention.
Cellular Data Off
If cellular data is off and the call is connected
through Wi-Fi, when the user leaves the Wi-Fi coverage area, the call will
automatically drop.
Using Carrier Minutes
There are cases, where it is not desirable for users to make
voice calls over Cellular Data, for example:
Cellular
Data coverage near the user’s area is flaky and weak
Cellular
Data is expensive
In these cases, users may choose to enable the Cellular
Assist feature which lets users make calls using Carrier Minutes (similar to
normal voice calls through native dialer) for their outbound/inbound call.
Carrier minutes settings should be used only in the
above-mentioned situations where the use of Cellular Data is not desirable.
Note that calls with carrier minutes still require an active internet
connection (Wi-Fi/Cellular Data) to initialize the call, but bandwidth with the
actual audio is consumed from the carrier minutes.

Though calls are made using native dialer, 8x8 ensures
that to the other party of the call, the user's work number is presented and
never reveals their personal number.

The table below summarizes the relationship between the
network selected for the call and user experience with respect to UI, call
quality, and the chance of call drop.

If the
user allows Cellular Data for calls and the user moves out of the Wi-Fi
coverage area, the call is automatically handed over to Cellular Data without
the user taking any action.
If the
user has not allowed Cellular Data for the calls and the user moves out of
the Wi-Fi coverage area, call drops as there is no network interface to hand
outcalls to.
