If you currently own a device that is on contract with a network provider, you are tied to using that sim.
Is there a Legal Method to Permanently Unlock iPhone 7/7 Plus?
Fortunately, there is a very straightforward way and does not require the use of any complex software that could brick your phone. Nor does it involve opening your device to modify the hardware to allow the use of another SIM. The process is called IMEI whitelisting, and you can only do this with the certified iPhone unlock service provider like DoctorUnlock.net .
The steps that you need to take are simple. First, do an online IMEI check on your device using the tool provided on this website. Once you know your eligibility, simply order an unlock for the device in question and await unlock instructions that will arrive via email.
We will whitelist your IMEI number from your carrier database. Obviously, this requires special access that only a few providers are granted. The unlock is delivered over-the-air using either a cellular connection or WiFi. This will allow you to use any SIM card, which is extremely useful when you travel overseas and do not want to be shocked by ridiculous roaming bills when you get back home.
You may also want to try out other networks because they offer different bundled services or simply because they offer better signal coverage in your local area. Whatever the reason, doing an unlock on iPhone 7/7 Plus will give you the freedom of choice over the course of your contract period.
