You should set maxReceivedMessageSize=”2147483647″ to increase message size. Try to change config to this:
<binding maxBufferSize="2147483647"
maxBufferPoolSize="2147483647"
maxReceivedMessageSize="2147483647">
<readerQuotas maxDepth="2147483647"
maxStringContentLength="2147483647"
maxArrayLength="2147483647"
maxBytesPerRead="2147483647"
maxNameTableCharCount="2147483647" />
</binding>
But it is a bad practice to increase you message values to max value. This can lead you to serious troubles with DOS leaks.
