||||| Service Provider
Locks ||||
SP Lock stands for a code your service provider
put in your phone to prevent the ability to use this phone with a SIM Card
different than the one you purchased it with.
This is due to a commercial trick: usually,
Service Providers sell phones and SIM cards together at a lower price than the
phone itself because they will earn from your telephone bill the money they not
charged you on the phone. Well, it's easy to understand they are not very happy
to let you spend such money with a different provider. If you ask a Service
Provider to unlock your phone, it will ask you some money to cover the income
it will not earn from you.
The code your Service Provider uses to lock the
phone may be freely selected and so, theoretically, there is no software which
may calculate it. In practice, they often use an algorithm to obtain a
different code for each phone from their international code and phones IMEI
number (which are both unique), to avoid the case of duplicate codes.
However the code is stored in memory and may be
read with the right equipment and knowledge.
At very first, you need a PC and an interface to
connect your phone with it; second you need to know the memory map of your
phone (each phone's model has its own); now you're ready to make a dump of the
Eprom of your phone and read there the code you are looking for.
Little by little we'll collect info about the
above mentioned interface or memory maps, we'll add them to the page of the
phone it applies to.
