At some point, most people won't only use one kind of network in their life. But considering that switching your current device to use another network is too wasteful, and not everyone can afford it, many of you are likely to use some ways to unlock your device from a specific carrier.

To make such a thing more straightforward and quicker, this guide collects FOUR easy and quick universal ways to unlock your phone (iPhone or Android) from any carrier. 

Part 1. 3 Universal Ways to Unlock SIM Card on iPhone

iPhone users have three ways to unlock a SIM card from any carrier. Now, let's review these ways and select the one you prefer to use.

Way 1. Unlock a SIM Card on iPhone with PUK Code

The official (and the safest) way to unlock a SIM card-locked iPhone is to get a PUK code from your mobile provider. This requires you to provide some identity to prove you're the owner of your SIM card. To know more details, check the following steps. 

Step 1. Use another phone to contact your customer service. 

Step 2. Provide your identity as required, and then get the PUK code.

Step 3. Enter the PUK code on your iPhone to unlock your device. 

Enter PUK code on your device

Pro tips: If your provider is AT&T, you can get the PUK online. All you need is to sign in to your AT&T account, click "My wireless," and select your device under "My devices & add-ons," click "Manage my device," and then click "Get your PIN unlock key." Then, you can enter the PUK code on your device to unlock it. 

Way 2. A Safe Way to Unlock SIM Card on iPhone Without PUK Code

Suppose you can't contact the provider or think it troublesome to contact the provider. In that case, an easier and quicker option is to use this free iPhone unlocker - EaseUS MobiUnlock.

Way 3. Unlock SIM Card on iPhone via Online Services

Some websites also provide unlocking services. No installation or registration is required. All you need is to provide information like your device model, the country and carrier with which your phone is locked, and your IMEI number. Then, submit your order and wait for your device to be unlocked. 

The price to unlock your device is based on factors such as your device model, brand, and the original network. Once you pay for the service, it will take a few days to finish the unlock process. 

The pros of such sites include convenience and ease of use. But on the other hand, they are easy to cheat your money. To some extent, such services are not as safe as the other two methods introduced in this guide.
