hi friends... Can @scorpius or anyone pl help me to know whether I can simply change my sim between yappari and whatsapp? Some solution was given to this issue, but I am unable to locate the post.

I am using Yappari for my personal mobile no. All my contacts are sync with my personal no in Yappari. I could remember that once the same sim card is removed from yappari and put into some other mobile, whatsapp was throwing some registration issue... so as per my understanding (pl correct me if I am wrong) i cannot simply suffle my sim card between yappari and whatsapp.

Thanks in advance.
