Reading this thread, I wondered whether a newer version of some BVRP software might do what seems to be wanted in the OP.
Some years ago whilst working in SE Asia, I bought a Bosch GSM908
cellphone. It got damaged, so I bought a newer model Bosch 909DS
(dual waveband) and as I also wanted to be able to download/upload phone numbers between PC and phone, I bought some PC software in New Zealand that was sold under the Bosch label with the name Data Interface
by BVRP Software (bvrp.com).
Here's a PDF of the User Guide that came with the software: Bosch - Data Interface Eng.pdf
The software provided for:
- Data File Transfer
- Terminal emulation
- via an RS232 interface. I got Data Access enabled to my NZ Vodafone account and found that I could set up the phone as a modem to the PC and connect through it to an NZ dial-up ISP for Internet access. It was slow, but it worked. All in all, it was a pretty good piece of software.
However, the most useful functionality for me was that, regardless of what country/network I was using, I could "use the PC as though it was the phone"
- i.e., I could download stored and incoming SMS messages from the phone, to my PC, and send/receive SMS messages directly from/to the PC, via
the phone. So I could type in my SMS messages on my laptop, which I found far more efficient than all that finger-and-thumb texting, and, furthermore, I could retain all the data on my laptop - which was regularly backed up.
I haven't come across any software quite as comprehensive or effective as this since.
