Just bought my first TSC3. I have had two TSC2's since 2006, the second one finally bit the dust. Still works, but the screen is flaky, already replaced it on this one with a screen that had been replaced on the other one before it died. Can't complain, 10 years for something that took a beating (and several dunkings) isn't bad at all.

I put an AT&T sim card in the TSC3. Works fine. But, when connecting to a VRS if I don't have it already connected it won't connect by itself. So, I have to start IE before going to the VRS, as IE makes it connect.

Is there something I am missing in the configuration that would solve this minor irritation? At least on the Yuma there is an app (Air Card Watcher) that will connect manually or automatically on power-up.

John,

I have used the TSC3s since they came out to run our local network VRS (LSU c4g) with an AT&T connection. Our's wont connect to the VRS without turning on the phone under wireless connections, and then "Connecting to GPRS" by opening a page in Internet Explorer. Once you do this, then you can connect to the VRS. It's like the data collection software (we are running SurveyPro) can't stimulate a cell phone/data connection. It has always seemed stupid and poorly thought out to me. The Leica collectors I have run connect and are up and running in seconds with the push of one button. If you find a solution, please post it up.

Yea, that is what I have to do, connect to a page in IE. Seems dumb.

There are "Internet Setup" and "Internet" icons in Access from the survey screen once you've opened/started a job. It can initiate cell service for you. You may have to scroll to see them. There were some major glitches with the call/hangup in the first generation of the TSC3. Required hard resets, etc. if you didn't know the proper procedure (which I've forgotten since...).

Thanks, Bill. If I go to the internet icon, it opens IE. So same procedure, just able to do it inside access without going out to the windows prompt.

I never cared for the internal modem, have always used personal MiFis instead. Same data plan, works a lot better, and has the added plus of being able to connect other devices to it.

Our mifi and phone hotspots are verizon, the internal modem is AT&T. Nice to have an option when signals are weak.

The TSC3 modem is not the best. In marginal signal areas you might be better off with something external. I found non-smart 2G phones worked best.
Another trick I have had to use is to change the internal modem to 2G only.
