There is no service that was shut down, the telecom company in question is now charging for traffic going to Wikimedia Foundation domains where before they did not. Edit to clarify: "Wikipedia Zero" is an initiative by the WMF to get telecom providers to allow their customers to access WMF projects without incurring data usage fees. If your telecom provider participates, you don't have to do anything special or different to access "free Wikipedia", you just go to the normal mobile Wikipedia page and you don't get charged for the data.
