Cell phone unblocking or remote unlocking is something that is made out to be a taboo by most phone companies and networks, and many people think it is illegal. The truth is there is nothing illegal or taboo about cell phone unlocking, and the unlock codes are readily available. If I wanted to unlock my phone’s network, I would need an unlock code.
This is because all cell phone manufacturers and networks programme their own network as a preferred network into the phone’s own electronics, but not in the SIM card. The network unlocking code needs to be obtained from the network service provider (Vodafone, Orange, O2, etc.) of the cell phone handset, NOT the provider of the SIM card. Once you have input the cell phone unlock code into the handset the phone should then be compatible with a valid sim card from ANY network provider.
There are also a huge variety of websites and forums dedicated to remote cell phone unlocking and unlock codes. They can offer tips, advice and support, as well as step by step walkthroughs of how to unlock your phone, making it easy for even the least technical of us to unlock our cell phones without having to pay or even contact our network service providers.
Many network service providers are happy to unlock your cell phone for you, if it means you using their service over that of a competitor service provider. Talk to one of your local sales spokespeople for the network service provider you want to switch to, and they may be happy to provide you with the unlock codes needed for remote unlocking, or even unlock the cell phone for you.
There are shops and market stalls that advertise a phone unlocking service, a charge a fairly steep fee for the privilege, but you should be wary of using these. Using their services can mean there is the potential for invalidation of the service agreement for your phone, and this may prevent you from using a SIM on a different network. It can also occur that upon purchasing a sim card from one of these shops or stalls that the case may be they have not unlocked your cell phone, but is simply locked it to a different network service provider that is not suited to your tariff needs.
A small piece of advice for anyone attempting to unlock their cell phone, sometimes the memory of the device can get wiped or partially erased in the process, and often cell phone handsets will revert back to default factory settings after remote unlocking. It is advisable to create back up of any important files and information stored on your cell phone before performing the remote unlock.
