Apart from offering a consumer the ability to search a multitude of network providersas opposed to just their current carrier, there is a few other factors why you may wish to SIM unlock your mobile even before the end of your contract. You might be moving to foreign countries as an example, it's advisable to take advantage of a domestic sim card while you are there to keep clear of steep roaming service fees. Or maybe you've decided to sell your phone then you'll probably get a higher price and much more interest in a cell phone that is free to make use of with any carrier.
Nothing could possibly be criminal about unlocking your smartphone. It's yours and you are therefore well within your rights to make use of it on any network you wish. Unfortunately, there's a good chance unlocking your cell phone may end your warranty, so it may be best to hold off until you have finished your contractual obligations before you decide to ditch your current provider.
A few carriers won't chargeyou for unlocking advice while others can easily charge as much as $60. It's also worth bearing in mind that each providers has varied guidelines pertaining to how long you might have had your regular monthly or sim only agreement for and how to get your cellphone unlocked. Just about all networks have online forms to submit a sim unlocking request, but some will advise you to call their helplines. Just how long it will take to unlock your smart phone yet again can vary greatly between each network. In the UK, Vodafone for example, will unlock an iPhone in a week, while Sky Mobile state it might take up to 25 calendar days to unlock SIM locked devices.
If you're unsure which business you can trust, I highly recommend Unlock.Zone. I've used them myself and was very happy with the service I received, and ultimately that they successfully unlocked my mobile phone. They supply unlocks for all major makes and carriers, give a guaranteed price match promise, plus most importantly, offer a full refund policy in the unlikely event they can't unlock your phone.
