Out of my head are some notes which may be of use, plus I did a bit of hunting around for the software needed.
I knew nothing of Zte "Join Me" software for PC nor Telecom NZ "R1" phones.
However, it reminded me that in about
1998 I used some third party software (I dimly recall that it was developed by a French software house) from Vodafone NZ for a Bosch mobile phone and which enabled the user to do some clever stuff with moving SMS text data and phone number data both ways between phone memory
OR phone SIM and a PC (I used a laptop) via an RS232 interface.
This was really handy and I used the Bosch phone as a central device to manage and sync the contents (typically telephone contact numbers) of multiple SIMs taken from non-Bosch phones that could NOT use the software/interface directly. The data was
forced onto the SIMs, overwriting all existing data.
The software also enabled the Bosch phone to behave like a modem, and the user could send/receive fax and SMS
from the PC
through the phone - typing the SMS messages on a keyboard was far better/faster than using a phone keypad.
If you had set up a Vodafone "Data Account", you could also connect to the Internet through the phone - I tried that, but didn't use it much as it was a bit slow - slower than a 56K modem, anyway.
I stopped using this method when I wanted some newer technology in my mobile phone, and anyway RS232 interfaces eventually became became a pretty rare item on laptops.
It was very handy and I have seen nothing quite like it since, but the Zte software described sounded a bit similar.
In 2005/6 I used some software that did something similar to the above, but via a Bluetooth interface. It worked on a range of cellphones, including the Ericsson that I was using at the time. It was called
floAt's Mobile Agent, which might be a defunct hyperlink now, but there might be copies of the website (and the software) on
Wayback at
https://web.archive.org/web/*/http://fma.sourceforge.net/
Wayback is really handy sometimes as their archives often have the downloadable software that was available when a snapshot of the site was archived. Just in case, I tend to make a local copy of these Wayback archived sites when I want them, using the FF
Scrapbook extension (just plain standard Scrapbook, not any of its forks), which also saves any related files from a website - if you tell it which file extensions you want it to sweep up as it saves.
Wayback gives the following links for Zte, but I have not been able to investigate them at the moment as I am hard pressed for time and also having major performance problems with FF, for which I am trying to locate the cause.

EDIT 2015-10-15 0506hrs:I have discovered the cause of the "major performance problems with FF" - and it's not just FF, but anything using the Internet. My daughter was given access to a family member's Steam library and has been downloading several games and playing them, including
Fallout Las Vegas (because she already really liked Fallout 3), and
Civilisation V - the latter which she describes as her "new addiction".
Some of these game downloads are 7 or 8 gigabytes at a time, and I watched a full-length HD SF movie the other night which probably broke the camel's back and blew the broadband cap. So it's been throttled back to dead slow now...
