Service Provider Lock Information :-
Service Provider Lock Service Provider lock is the lock to your phone which is implement by your service provider e.g. Orange onto your sim card. The phone is usually locked to a certain SP but it can be unlocked allowing you access to other service providers that provide a better deal. The same effect can also be used by using a Dual sim, you could have two sim cards in one phone allowing you to switch between sims and SP 1. First sim = Orange 2. Second sim = One2One
Short Message Serivce Centre Numbers ( FREE SMS ):-
SMSC (Short Message Serivce Centre Numbers) SMS Centre number allow you to send free sms, by changing your message centre number like this:
1. Go to messages
2. Message Settings
3. Set 1
4. Message Centre Number
5. Then change the number to one from SMSC Number section (from SMSC #'s given below)
What does this do?
Instead of paying for your messages, you can alter a number in your phone to send to a different centre. This cannot charge you, and consequently you have free SMS!
How does it work?
When you send a text message, it is first transmitted to your network's routing centre, called the Short Message Service Centre, or SMSC. This SMSC is generally a telephone number, normally a memorable one- i.e. Orange's is 0973 100973. Here, it is sent to the recipient's network's SMSC, where it is then forwarded to their phone. The whole process takes only seconds, but the vital part is when it reaches your SMSC, because then it is forwarded, and you are charged according to your tariff. If you, however, change your SMSC number to one below, the network who forward the message will not know who you are, and consequently cannot charge you. Clever huh?
Does it always work?
No! It can take hours to find a number that hasn't been blocked by your network- they usually carry out checks monthly and bar any numbers known to be forwarding SMS. Also, I understand that Orange and all networks in Denmark have barred all numbers aside from their own- so it won't work with Orange or Danish networks.
ISDN Number :-

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.
