This is my own assumption into guessing why MultiSIM will not work with NumberShare.
For MultiSIM, it uses the same mobile number and because NumberShare also uses the same mobile number, there might be a conflict.
For MobileShare, you will be given a different number. Is just line with an empty plan with data/call/sms shared from your main number.
So technically, you can MultiSIM your MobileShare line as it is a different number if Singtel allows it.
