Depending on your location - I am in Ontario       Contact   Rogers or Telus  for the SIM cards.


Also, during the configuration, be sure to set the unit to the proper BANDS, they are different from the

programmed bands.  The command is detailed in the big programming manual.

If you need a copy, I can email it to you.      dant@sandtron.com
