Power off the Digi 6350-SR/6355-SR, swap the antennas on the
n
back of the Digi 6350-SR/6355-SR, and power on the Digi 6350-
SR/6355-SR. 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 6350-
SR/6355-SR, but we suggest that you eventually order a
replacement set of antennas to improve signal strength even
further.
If swapping the antennas did not resolve the issue, verify the

the SIM card is provisioned properly. If it is, then there may not
