My Pocket WiFi says it's out of coverage. What should I do?

If the signal icon is in red and it looks offline, please try the following steps and see how it goes.

  1. pull off the back lid from the right bottom corner while it's turned off 
  2. remove the battery 
  3. slide to open the sim slot cover 
  4. take out the sim and re-insert it
  5. slide to close the slot cover and put everything back on 

Here is the video for you to fix it in 30 seconds.

(It's also possible that it actually is out of coverage area if you are in very rural areas in Japan.)
