I work for a surveying outfit based near St.Louis MO. We are running Javad Triumph GPS receivers with ATT 3G SIM cards/modems. For almost a month now we have not been able to connect to our DOTs network using the GSM function on the receivers. Anyone else having issues with ATT specific 3G connectivity? Or any other issues like this with gps equip? Any ideas/experience will help. Thanks!
What did Javad tech support say about that?
What APN are you using?
Hi Trevor,
Please email or private message me with the serial number of one of these TRIUMPH-1 receivers and we??ll investigate the issue.

Has ATT already started shutting down 3G in some areas? By 2022 it is all gone......
