  • [1]When the wireless LAN communication speed is 72Mbps, while the 3G network communication speed is 9.2Mbps. Service is on a best-effort basis. The stated speed is the maximum value based on technical standards and does not indicate actual speed. There may be significant decrease in speed due to the usage environment or network conditions.

Advantages of Wi-Fi!

Compared to 3G network (downlink speed is 9.2Mbps) Wi-Fi achieves 7.8-times greater speed [2] (up to 72Mbps) and enables smooth downloading of apps!
