n Power off the Digi EX15, swap the antennas on the back of the
Digi EX15, and power on the Digi EX15. If this resolves the
connectivity and there are two or more bars of signal strength,
this may indicate that one of the antennas is faulty. You can
continue to use the Digi EX15, but we suggest that you
eventually order a replacement set of antennas to improve
signal strength even further.
n If swapping the antennas did not resolve the issue, verify the
SIM card is inserted properly. Power cycle the Digi EX15 after re-
insterting the SIM card. Wait 30 to 60 seconds. If the problem
persists, the unit cannot detect the SIM and the Digi EX15 may
need to be replaced.
