Hi could you please help me to unlock the security codes for noki2630?

Unlock codes are a code that is created for the Nokia 2630 phone and is unique to its IMEI (serial number) usually one code is supplied, once it has been entered into the Nokia 2630 mobile phone the phone is unlocked and able to use any simcard.

If you got this phone from a company like AT&T or T-mobile, you could probably get the phone unlocked by the service provider free of charge. You need to call your service provider (customer support), and tell them that you need an unlock code for your phone. They will ask why you need it. Tell them that you will be traveling over seas and that you will be using a pre-paid sim card within the country that you are "traveling" to.

If this option is unavailable to you, there are other ways to unlock your phone. There are websites that provide unlocking services for a fee. One website is otherwise you can google "unlock phone service" and try to find website you are more comfortable with.

I hope this helps.

Please help i wanna unlock my n73

You're probably trying to use a SIM card from a network not supported by the country you're in.
Some networks don't have a roaming agreement between two or more networks service providers to enable the users of one service provider to use their services.

Purchase a new SIM card from a popular network in that country. Ask them to unlock your phone at the same time, because it might be locked on the original network, like Orange, Vodafone, t-mobile etc...
