[Resolved]  Airtel — Unable to connect to a reliance number

Sir,I have been using an Airtel prepaid number from last two years,The problem is that I cannot connect to my home number which is a reliance number.The problem is happening from the starting date I changed my moblile but no use it is the same problem.Do you what ti says when i dial to the reliance no. It says "
The no. does not exist Please check your number and dial again".But if I try the same no. at the same instant from any other mobile connection, I do get connected.
I don't understand what is the problem with these mobile service providers, Might be disputes between them make all these.Please help me what should I do ?Is it all for what we buy a mobile SIM?When we do not get connected to any different SIM users what is the use of these many telecom companies there should be only one unique company.
If needed i can provide a video of the call.
Details :
My no. is [protected] (silchar,assam)
My home no. is [protected] (Vijayawada,Andhrapradesh)
