There are so many people who buy locked phone from the network carriers and later to worry about how to unlock their phone to enjoy the best deals offered by other network carrier services. The unlocking services are in fact offered by the network carrier who locked your phone, but only if you have met his terms and conditions. But there is still an option open for you to unlock your phone through the third party unlock phone services offered online. By availing their services for a fee, you can easily have any of your phones unlocked irrespective of the phone model or the network carrier service. If you want to unlock Orange phone all you need is to just contact them online and send across your phone IMEI number. The unlocking services shall send you a code and the instructions on how to unlock the phone using the code. It is that simple and you don’t need any technical skills or knowledge to unlock your phone. 
 

 
If you want to unlock Orange iPhone the same process applies like sending the IMEI code and getting the unlock code. But you can also unlock iPhone using latest version iTunes. You have to first install iTunes into your phone through internet connectivity. Then connect the phone to iTunes with a not accepted SIM card. As iTunes detects the phone disconnect the iPhone and connect it again to have your iPhone unlocked permanently. The third party unlocking services can unlock all iOS versions and it remains unlocked even if you update to latest version of iOS. 
 

 
Similarly, to unlock Optus phone which is generally locked to a single carrier you have no other option rather than availing the phone unlocking services online. They need the phone IMEI code and the model number to send across the unlock code for your Optus phone. You should then insert a non carrier SIM in the phone and switch on. The phone prompts for a code and you have to enter the code for more than 10 times to finally have your phone unlocked. The same process applies either to unlock O2 phone or unlock Optus iPhone.  
 
There are so many benefits with unlocked phones as you no longer have to pay the roaming charges when you are traveling abroad by switching to a local GSM carrier. You can also choose the network carrier offering better deals in the market and above all the resale of your unlocked phone multiplies.
