常见问题
What is the most common reason data slows down after several days?+
Most often it is the plan's fair-use threshold being reached, which drops speed automatically rather than cutting off access entirely.
How do I know if it is the fair-use policy or a different problem?+
Check usage against the threshold on the plan page first. If close to or past it and things still load, just slowly, it is likely this policy. If well below it, look for another cause instead.
Will buying an additional plan always fix the slowdown?+
Only in the case where the real cause is the fair-use threshold being reached. If the real cause is local network conditions or the phone latching onto a weak signal, buying more will not fix it.
Do I need to restart the phone every time it feels slow?+
Not always, but it is an easy, safe step to try when a weak signal is suspected. Do it after checking remaining data first, not before.
If every step has been tried and it is still slow, what next?+
Message us on LINE or by email with the plan's details and what symptom occurred. We can help look into it with the information available.
Can manual network selection fix a slow connection?+
It can help in some cases, especially when the phone attached to a partner network of lower quality than another available in the same area. Try switching to the next one on the list.
