i got the companion working. Dont know exactly where, but you can find the companion for the TS on Google+. The developer is Kurt Huwig.
Must install Truesmart Master app from playstore.
Its working fantastic with my Zopo ZP980 dual sim phone. For both numbers, incoming calls are displayed on the TS and i can accept or cancel the call.
Even SMS is working fine, for both numbers.
Fantastic app, so I have now my standalone TS with the SIM and 3G, and also my companion TS, paired with my smartphone. Very happy about that.....:good::good::good:
