Ensure that Mobile Network is Turned On for the SD7
Look for Cellular Signal bars and the 4G LTE Icon at the top:
Menu > Network > Cellular > Cellular Data > Click to On/Off - If it says click to "On", click the top knob down once, it should say "Click to Off" when it is set up correctly
- If the previous stop shows "Click to Off", ensure that the SIM card is seated and secured properly underneath the battery and that the SIM card tray is locked in place
- If the SIM card is locked in place correctly, and the device still does not work, please double check the Mobile Number, IMEI and SIM card number are all aligned in you Wireless Carrier Business Account for this line
- If all of the above are correct, it may be that the SIM card has an issue, and the SIM card will need to be replaced.
You can always try another working SIM card from a different device and place it into that device, and if it works you know the original SIM card is bad and will need to be replaced by your Wireless Carrier Sales Rep.
