Let me give you a little background and then some solutions. This is generic because I don't know your carrier. I'm using ATT as an example.
Phones are naturally unlocked, but a service provider might lock them
When originally manufactured, all GSM cell phones are unlocked. That is, they can be used with any SIM from any cellphone service provider - always assuming, of course, that the cellphone service provider has compatible GSM service on the same frequency bands that the phone can operate on.
Most cell phone service providers electronically 'lock' the phone so that it can only be used with their service. There are obvious reasons why they choose to do this - in particular, to force you to pay what are usually very high roaming charges when you take your phone out of their network and use it elsewhere in the world.
Fortunately, this locking is reversible. With some phones, it is possible to simply enter an unlocking password code into the phone and it is immediately then unlocked. Other phones need to be connected up to a special unlocking data terminal.
Your phone has to be unlocked by the carrier. LG, Motorola, Sony Ericsson, Nokia and most of their ilk, will not give consumers the unlock codes but don't despair.
A PUK (PIN Unlock Key) code is required to unlock SIM cards that have become locked following three successive incorrect PIN entries. If your SIM card becomes locked, you will need to get a PUK code from your carrier. For example, if you have AT&T to unlock your SIM card, you can obtain your phone's PUK code from AT&T by:
● logging in to your my wireless Account online ● using their Technical Support Chat ● calling Customer Care at 1-800-331-0500
To get your phone's PUK code online from ATT:
● Log in to your my wireless Account. ● Select My Services under My Account. ● From the My Services screen, select My Phone/Device. ● Select Unblock SIM Card. ● The Unblock SIM screen will display your PUK code.
Once you receive your PUK code, you will need to enter it into your phone to set a new PIN code.
Note: If you enter the wrong ATT PUK code 10 times in a row, your SIM card will be invalidated, and you will need to purchase a new SIM Card. The phone will display the following error: "PUK blocked call operator."
There are three other ways to unlock a phone:
● The carrier will unlock the phone for you at one of its retail outlets; ● You can do it yourself by clicking on this link Free Unlock Codes , ● Pay $3.89 at the following website: www.theunlockshack.com/. (I have no affiliation with this company!
I trust that this is helpful and solves your problem. All the best
I've had this happen twice, both times when I tried to quit during a
long web page download. Just taking the battery out briefly won't help
though. It has to be out for somewhere between 12 and 24 hours. Probably
there's a capacitor or a small battery that has to drain in order to
reset some volatile memory.

I had this issue before, I replaced the battery with a new one! a chinese one like the old one, it worked fine for like 4 months, then the same problem occured, I am now willing to buy a new battery but not chinese one I guess it was a big mistake to buy Nokia 7510 Supernova! now I am using a chinese mobile phone "double SIM card" and it's working really fine with me
You
can
get the unlock code by contacting your current service provider
customer care department. If your phone is locked you can use any of
your friends phone to make this call. The
service
provider will then provide you the unlocking codes. Remember
that the reason why the codes are provided only through customer service
provider is that, they will make a check on your name and identity proof
at
the time of your call. If the information is found to be correct and
matching with their data then you will be provided with the codes.
Everything is done for free of cost and you are not going to be charged
for this process.This
is
the universal solution and is useful for many customers who are
facing these kind of problems. Don't believe in any websites which
provides unlock codes. All are fake. Only your service provider can
provide these codes.
Another alternative is, you can take the
phone to any authorize phone service center to help unlock the phone,
because to unlock your phone, you will need some kind of software, USB
cable
etc to unlock the phone, so you can also go a nearby phone service
center to unlock the phone,
but calling your network service provider is the best because they have
the records of your phone and can easily help to unlock it. This are the
two reliable means you can unlock your phone.
Carefully disassemble the phone, take a Q-tip with a little alcohol on it & clean the contact on the back of the 7 button, as well as the area that it touches on the circuit board. While you have your phone apart, go ahead & clean all the key contacts. This always works for TV remotes with buttons that begin to fail.
It means that the phone is still alive but the firmware needs reinstalling. Nokia permits you to reinstall it from the net. All you have to do is to
1. Remove the memory card after fully charging the battery.
2. Set the profile to General.
3. Connect the phone to the PC and allow Nokia PC suite to detect the phone.
4. Follow the instructions to install the firmware.
5. The phone is supposed to reboot in between, so do not panic.
6. If, by any chance the phone does not wakeup after reboot then it is dead and can be thrown away (it has happened to me with my E61i).
So the best is to go to Nokia Care and get it done from them as when they do it, they do not depend on the net. Their firmware is downloaded fully before commencing the installation. Also they rewrite the whole firmware and not just required files only. And thus they remove the virus, because of which your phone may have got corrupted.
Take your pick.
