Just what are the advantages of an unlocked cellular phone?
Aside from offering the owner the chance to consider a variety of network providersrather than just their current provider, there's a number of other factors why you might like to unlock your smart phone before the end of your contract. Should you be moving overseas for example, you might want to take advantage of a local SIM-card when you're there to keep away from high roaming penalty charges. Or if perhaps you've decided to sell your handset then you'll probably get more money and much more interest in a mobile phone that's free to use with virtually any network carrier.
Nothing is illegal about unlocking your cellular phone. It's yours and you are within your legal rights to make use of it with any network you choose. Having said that, there's a very good chance IMEI Unlocking your smartphone will probably end your warranty, so it could very well be best to hold off until you have finished your contract before deciding to get rid of your current provider.
You will need to ensure your cellphone actually needs sim unlocking by entering a SIM card from a different provider into your mobile. If it's locked, a message will pop up on your phones home screenadvising you of this. The easiest way to carrier unlock your smartphone is to telephone your carrier and ask for a Network Unlock Code (NUC). A good number of them will supply you with one and some even do it for free once you have finished your contract. The moment you're supplied with this code you should be capable of input it into your cell phone to get rid of the lock. This is the easiest and most common method of unlocking.
Once your mobile is unlocked, you are ready to find one of the lowest priced cellular packages available - a SIM only package. All these usually operate on a rolling month to month basis, meaning you can use the package for so long as you are content with your cell phone or you can update when the next device is released or your trustworthy old cellphone sooner or later gives up the ghost.
If you're not sure who you can trust, I highly recommend Unlock.Zone. They supply unlocks for all major brands and networks, have a guaranteed price match promise, plus primarily, have a 100% refund policy in the unlikely event they can't unlock your phone. I have used them myself and was very happy with the service I received and ultimately that they successfully unlocked my cell phone.
