Looking for a way to perform the function equivalent to: *#*#4636#*#* --> 'Phone Information' --> 'Set preferred network type'

Because above code is not working on my both phones SGS3 LTE (GT-i9305 and GT-i9305T)

The article Change WCDMA to GSM automatically is for SGS2 and it doesn't work for SGS3.

Are there any alternatives?
