From Binh Thuan to Da Lat city, Lam Dong province, there are many routes, including 3 main routes: National Highway 28, National Highway 28B, National Highway 55 and all of them are connected to National Highway 20. When merging Binh Thuan into Lam Dong, the roads were more crowded with vehicles.
However, many locations on the mountain pass, especially Dai Ninh Pass on National Highway 28B, have many sections that are missing 4G waves, some sections have lost phone waves, affecting users.
Mr. Tam - a bus driver running the Da Lat - Phan Thiet route said that the locations where the phone signal was lost caused communication disruption. Or the vehicle's tires are unfortunately flat in these locations, making it difficult to patch the shell.
There are sections on the pass, where 4G waves are converted to 3G, affecting users' ability to watch movies and listen to music online. There is also a situation where passengers on the car want to read the email that the customer has just sent with a large amount of attached documents but cannot connect to the network to read it, so they have to wait until the 4G signal is back.
Losing 4G waves to connect to the internet, usually the phone only has a 3G icon, but the transmission speed is very slow, almost unresponsible. And the sections that lose 4G mobile waves often last from 5 - 10 km.
National Highway 28B is being upgraded and repaired. Many people hope that the telecommunications system on the pass routes will soon be upgraded, ensuring smooth connection and meeting the needs of road users when traffic volume is increasing.
