常见问题
Does frequent network switching mean the profile is broken?+
Not necessarily. Most of the time it is normal behaviour of the network-selection mechanism while moving or where several networks are close in quality.
When should I start worrying about network switching?+
When switching causes an unusually long drop every time, or causes an app in active use to disconnect mid-way often enough to genuinely disrupt use.
Is selecting a network manually safe to do?+
Yes, it is safe, but switch back to automatic before moving on — otherwise the phone may have no signal if the chosen network is not reachable at the new spot.
Does frequent switching drain the battery faster?+
It can use somewhat more battery during periods of frequent searching and evaluating, though the real effect varies by model and environment.
I cannot find the manual network-selection menu — what do I do?+
The menu location differs by manufacturer and OS version. Try searching together with your specific model name, or use our device checker for an initial read.
I tried manual selection and still have an issue — what next?+
Message us on LINE or by email with your device model, the country, and what you are seeing, and we will help check it and suggest a next step.
