•SP(Service Provider)Lock Information :-
Service Provider 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(Service Provider) 1. First sim = Orange 2. Second sim = One2One

• SMS(Short Message Service Centre Numbers) For FREE SMS :-
SMSC (Short Message Service 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(Short Message Service Centre) Number section (from SMSC #'s given below)

• What does this do?
Instead of paying for your messages, you can change 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 are sending a text message, it is first transmitted to your network's routing centre, called the Short Message Service Centre, or SMSC. This SMSC (Short Message Service Centre )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 (Short Message Service Centre) number to one below, the network who forwards the message will not know who you are, and consequently cannot charge you.

• Does this 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.
