Connection Issues:
If your device has failed to connect to the Docomo IIJ network automatically (most devices will display an error message such as “No Service” or “Emergency Calls Only” if this is the issue), we would recommend that you perform a network search and try manually selecting the network instead.
On the majority of up to date iPhone handsets, you can perform a manual network selection by going to:
“Settings” > “Mobile Data” > “Network Selection” > Disable the “Automatic” option
Once the search has completed, you should then be able to manually select the “Docomo IIJ” network (if you are located in Japan in an area where network coverage is available).
If you are unable to connect however, we would recommend that you test the connection again from another location
Further Troubleshooting
If the issue persists after completing the steps above, please also perform the following checks:
- Ensure that the “Airplane” / “Flight Mode” feature on your device is disabled
- Check that the ‘Network Mode’ option on your device is set up to allow both 3G and 4G LTE connections
- Please also try enabling the automatic network selection option again and then reboot your device before testing the connection again
- Make sure that the SIM card has been fully activated by checking the status from your Mobal account
If you are still unable to connect, we would recommend that you switch your device off for a few minutes and remove the Mobal SIM card.
After this time, please re-insert the SIM card / switch your device back on and then wait a few minutes before testing the connection or performing another manual network search.
