MTS, Kyivstar and Life support number parking.
To my big regret the parking didn't work in my case several days ago. My main Ukrainian number is Kyivstar one on the contract basis, so the calls forwarding works well. So before my journey (on the 1st of September) I tried to run parking for several times but each time I received the message that "You haven't set up the call forwarding on your sim card" (or something like that, I can't remember the exact message). After those attempts I proceeded with the manual installation of the call forwarding and found that it was installed to the phone number +380947112592 for all possible cases. I switched it off and on again, but nevertheless the parking was unsuccessful.
When I came to the destination country (GB), I bought the local sim card, put it within my phone, ran the Roamer app and confirmed the usage of the temporary number. After that I found the curios situation that starting from that moment I could be achieved by both temporary and my main numbers ('cause the call forwarding is still on), but all my calls are displayed as from the temporary number.
I use the latest Android version of the application, my phone is Samsung Galaxy SII (i9100), its firmware number is I9100ZCLS4 (version of the Android installed is 4.1.2, unofficial ROM, rooted).
Also I tried to run the parking on another phone (of my colleague), but the results were quite the same. His mobile operator is also Kyivstar, the phone is Samsung Galaxy SIII (I9300), its firmware number is I9300UBEMH1 (version of the Android installed is 4.1.2, official ROM, not rooted).
Could you please share your suggestions regarding the issue described?
P.S. Anyway I'd like to thank you for the great software, I hope that for the next time I won't struggle any difficulties and will be happy having cheap calls' rates .
