I have recently bought a Reliance Netconnect mobile broadband device, and it remains in use all 24 hours of the day.
I have noticed that the device heats up after an hour or so of usage.
Is my continuous usage of the device likely to cause it any harm? Can it affect its functioning some way or lessen its life? Are there any cautions I could take in this regard, to ensure the proper functioning and long life for my mobile broadband device?
