Image of simultaneous connections are possible from multiple devices including smartphones, tablets, and PCs

You can use various Wi-Fi compatible devices such as PCs, tablets, and gaming devices in addition to smartphones.

Up to five devices can be connected simultaneously.

  • The number of devices is identified with MAC address.

Reliable Security

Communications may be intercepted or monitored at a public Wi-Fi SPOT that are not encrypted. d Wi-Fi uses the WPA2 system to encrypt wireless sections connected to access point devices for secure communication.

How d Wi-Fi Security Works

The d Wi-Fi offers wireless security between an access point and a wireless LAN device.

When transmitting important information such as personal information through the Internet, we recommend to use additional security such as TLS or VPN*2.

TLS and Internet VPNs ensure security even in wireless LAN areas, and therefore they are able to protect your connection even if the wireless LAN encryption is decoded.

  • When you log in to d Wi-Fi, TLS is used for communication between your device and a DOCOMO's server. This encrypts your d ACCOUNT and d Wi-Fi password information to prevent data from being intercepted or tampered with.
  • d Wi-Fi SPOTs support IEEE802.1X technology which supports automatic authentication with robust security.
    You can configure it on your device.
  1. You may not use some VPN technologies as d Wi-Fi allocates a private address to your device.

Content Filters Option

A subscription to the Content Filters Option, which blocks access to harmful websites, is recommended for minors.
