It sucks to be stuck to a single network connection, bound by some contract you have no say over. We get it.

In doing so you can't put in another SIM if it belongs to a different provider. And if you're dissatisfied with their service? Well then that sucks but nothing you can do about it! Or at least, that was true until recently. But now, all you gotta do is learn how to SIM unlock iPhone 7 or how to SIM unlock iPhone 5 or SIM unlock any other iPhone and you can snatch that power right back!

Part 1: Basic Info about SIM unlock

Is it legal to unlock SIM card?

This is a common question that people have. And the short answer is; yes. As of February 11, 2015, under the "Unlocking Consumer Choice and Wireless Competition Act" it is completely legal to unlock your phone. However, the wording on the law is pretty lax so the carriers may still impose their rules and hurdles to keep you by stating that you have to get past your 2 year contract or they may place restrictions upon how many times a year you can unblock it, etc. But those are just things they could do rather than what they actually do in practice.

Why do users SIM Unlock iPhones?

1. Access other Networks

This is one of the primary reasons. You could simply swap out your SIM card and easily get access to another network connection.

2. International Travel

This is the most ideal option for those who are constantly traveling internationally. This is because local carriers charge an exorbitant Roaming charge on international calls. However, if you have a SIM unlocked phone you could get a local Pre-Paid SIM and use it for the duration of your travel rather than pay such exorbitant rates.
