About SORACOM Beam Connections

I'm trying to tinker with the SORACOM that was announced last month, but
I stumbled while setting up SORACOM Beam.

First, I tried to check the connection to Beam, but now it is as follows.

configuration

• Configuring SORACOM Beam
• Assign SIM to group with Beam configured
• (Just in case) Stop SIM 利用 Re-use
• Put SORACOM SIM on your mobile router
• Connecting a PC to a Mobile Router on the

State

• Connect to the Internet (you can also view the Internet normally)
• ping www.google.co.jp 繋がるConnect
• ping beam.soracom.io < ping:sendto:Host is down
• curl http://beam.soracom.io:8888/
  ⇒ curl:(7) Failed to connect to beam.soracom.io port 8888:Operation timed out

This is the situation.
Please let me know if anyone has any helpful information in the situation where it does not connect to beam.soracom.io.

environment

OS:Mac OS X YOSEMITE
SIM:Nanodata Communications/SMS
routers:Docomo BF-01B
That's it.
