I have the same issue in Guatemala and have an open case. One thing I did find out was you needed to have SUPL enabled, and if you have a connection via WIFI with internet access it works and also if you use a cellular SIM in the MC67 and has internet access it also works.
Hi, We have the solution to this problem, we made a package that solves this problem. this solution found with SIM CARD and without SIMCARD. Your developers only write the parameters: Duration in time, Port, and Model, and de DSsolutionGPS return the latitude and longitude.
Send me E-mail with your problem and We help you.
I have the same problem. Can't open the port. had anyone find the solution please.
Thanks a lot.
