常见问题
Why does the phone pick a network that is not the fastest one?+
Because the radio prioritises signal strength above download speed. The two sometimes align and sometimes do not.
After selecting a network manually, does it need redoing every time you move to a new city?+
You should switch back to Automatic before moving areas each time, then consider manual selection again in the new area if needed, since staying on the old selection often causes a total loss of signal.
Does a battery-saving mode really slow the connection?+
On many phones, yes, since the mode automatically caps data speed and background activity. The exact behaviour varies by brand and operating system version.
If every network on the list has been tried and it is still slow, what next?+
Consider that it may genuinely be a limitation of that area at that time. Try testing again at a different time, and if you still suspect the profile itself is at fault, contact the team via LINE or email with the details.
Does manual network selection work in every country?+
The feature exists on most phones, but the partner networks that actually appear depend on the plan and destination country. We do not assert a fixed list of networks for every country — check that plan's own page for details.
