Essentially, there are two types of unlocking methods. One is called remote unlock by code, and the other one is unlock by an unlocking software with the help of a data cable. In my extensive research to hunt down free cell phone unlocking services I found that 100% of remote unlock by code were paid services.
But, we all love free stuff and phone unlocking is no exception. So that begs the question; are there any free unlocking services on the internet? The answer to that question is, not really. Let me explain. You may find some websites out there that do give away free unlocking software, but that software is primarily outdated and is most likely not going to unlock your phone unless you own a cellphone that was manufactured close to the turn of the century.
Cell phones are coming out at blazing speed. No matter you own a Nokia, Motorola, Samsung, LG cell phone or one of these latest Smartphone PDAs, in the time it takes for a person to fully acquaint themselves with their phone's functionality, a newer model is spitted out by the manufacturer. It's a fast paced industry and therefore great majority of free unlocking softwares out there are too outdated to cover new phone models.
There are websites that do offer softwares that unlock newer phone models and types, but you guessed it right, they usually sell those softwares for a price. These software vendors know that their software is current and worthy and therefore they tack a price to it. I did however find that unlocking phone by software almost brought down your phone unlocking cost to about half especially if you received your phone with a data cable, in which case you don't have to incur the extra cost of purchasing a data cable.
I found that http://UnlockAcell.com provides remote unlock by code services at a discount prices. On the other hand if you are interested in phone unlocking by software method, the website http://UnlockSoftwares.com has effective and late model phone unlocking softwares at reasonable prices.
