常见问题
Does the system's data saver mode block important apps?+
It generally does not block the app you have open in front of you, but it does limit background activity for apps that are not open. If a particular app genuinely needs to update continuously, check the data saver menu for a setting to exempt that specific app.
If automatic photo backup is turned off, do already-taken photos disappear?+
No. Every photo stays on the device exactly as normal — it simply has not been uploaded to the cloud yet, until backup is switched on again or Wi-Fi becomes available.
How much data should be bought in advance?+
Use the data calculator on the site, entering the number of days and a rough sense of usage habits, to get a figure close to your actual need, rather than guessing from a generic number.
How much data does sharing a hotspot with a friend use up?+
It depends entirely on what your friend does through that hotspot — streaming video uses far more than messaging. Agree in advance on what each person should download offline before connecting.
Is public Wi-Fi reliable enough to replace mobile data entirely?+
The quality and stability of public Wi-Fi varies enormously from one spot to another. It works well as a supplement for non-urgent activities, but should not be relied on as the main connection for anything needing stability while actually moving around, such as real-time navigation.
What should be done if data runs out before the trip ends?+
Check whether the four main data-saving changes have all been applied. If they have and it is still not enough, buy a top-up or a new plan through your destination's plan page, and always check the top-up option's terms before confirming.
