Enhanced Full Rate/Half Rate Enhanced Full Rate Codec :-
(EFR) For activation enter *#3370#
For deactivation enter *#3370*
Enhanced Full Rate Will give you much better sound quality when you enable it.
The new Enhanced Full Rate CODEC adopted by GSM uses the ASELP (AlgebraicCode
Excitation Linear Prediction) compression technology. This technology allows
for much great voice quality in the same number of bits as the older Full Rate
CODEC. The older technology was called LPC-RPE (Linear Prediction Coding with
Regular Pulse Excitation). Both operate at 13 kilobits.(but you take up more
space on the network, so they can charge you more) - Talk-time is reduced with
about 5%
Half Rate Codec
For activation enter *#4720#
For deactivation enter *#4720* In all cases the phone will automatically restart.
Half Rate will give you bad soundquality, which gives the serviceprovider the
opportunity to have more calls on the network, and you might get a lower charge
from them. - Will give you 30% longer talk-time.
