Frequently Asked Questions

Q. What is the difference between an optical line and a home router?
A. Fiber-optic lines require construction but the speed is stable, while home routers (WiMAX, etc.) can be used immediately with just an outlet, but there is no construction required, but the speed may fluctuate.
Q. Can I get a fiber optic line even if I am renting?
A. It's OK if it's already installed in a building, but new construction requires permission from the landlord. Even if the condominium type is not supported, it may be possible to contract for the detached house type.
Q. Will construction costs be free?
A. There are many campaigns that offer "virtually free construction costs." Please note that the monthly fee will be divided and offset, and if you cancel midway, you will be billed for the remaining balance.
Q. How do you choose a provider?
A. Compare prices, speed, support quality, and cash back. The major brands (OCN, BIGLOBE, So-net) are stable, and the low-cost ones focus on price.
Q. Which is better, pocket Wi-Fi?
A. Pocket Wi-Fi is a good option if you live alone and need less than 20GB per month, and if you use it with a family or watch a lot of videos, opt for a fiber optic line, which is stable and economical.
