I have read all post that support for calling WS from Windows Phone 8.1 has been removed and you cannot do more right click, or even import a proxy because some classes are missing.
Also I have read this that suggest changing the endpoint, but that is not an option since I don't own the server where I have to do a call. SOAP Service Reference in Windows Phone 8.1 Universal app
What other alternatives are there?
Maybe an HTTPClient that parses the XML?
Any other ideas?
