SOAP API alternative for geo-autocomplete - sabre

Question

Is there a SOAP API alternative for geo-autocomplete that is available in REST API? Is it EncodeDecodeLLSRQ? If so, it is always providing the below response when I try with the below provided request. I get the same response for the example provided in doc too.
<EncodeDecodeRS Version="2.0.0" xmlns="http://webservices.sabre.com/sabreXML/2011/10" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:stl="http://services.sabre.com/STL/v01">

I don't think EncodeDecodeLLSRQ was designed to do what you're looking for but it might just work. For example, when entering an incomplete city name, the service will return a list of possible values.
RQ:
<CityName>MONTEV</CityName>
RS:
<Text>MVD MONTEVIDEO, URUGUAY</Text>
<Text>MVE MONTEVIDEO MN, MINNESOTA,USA</Text>
<Text>FMV MONTEVIDEO FLUVIA, URUGUAY</Text>
<Text>VDT MONTEVIDEO TC BUS, URUGUAY</Text>
Do you have access to SOAP API? If so, could you please share the complete RQ to see if there's something wrong there?
