That article for setting up and using Dual SIM, which is already done. I am using both Lines from one service provider. I used them both lines with my earlier dual sim Android phone and worked fine with Messenger and all voip applications. When i transferred from Android to iPhone back in Feb i noticed this problem which i have see already reported from different users. So, i concluded that my problem is with ios and not with Messenger or the other applications. The problem still not solved.
