3G network closure regarding my mobile calls and SMS

[don4]

do I need a new Sim to continue my plan as is? 

does wifi calling and Text affect cost or connectivity or my current contacts?

Hi @don4, 

Let's check what options are available for you. Any chance you can PM us with your TPG account number or Customer ID? 

Thanks!
