How to Check What Cellular Carrier Network an iPhone Uses (or Used)

Find out which cellular carrier network an iPhone is using or has used by following these easy steps. This guide will help you understand how to determine the network your iPhone is connected to or was last used on.


It’s important to know the cellular carrier network that an iPhone uses or has used, whether you’re buying a new device, purchasing a used iPhone, or checking compatibility with your chosen network. Even if your iPhone doesn’t have a SIM card or cellular service, you can still find out which network it was recently connected to or used by accessing the device settings. Simply go to the Settings app, select General, and then tap on About. Look for the Network and Operator settings to view the active network and the last network used by your iPhone. This information is useful for determining if your iPhone is locked to a particular carrier and for ensuring compatibility with your desired provider.


1. How can I check which network my iPhone is currently using?

To check which network your iPhone is currently using, follow these steps:

  1. Open the Settings app on your iPhone.
  2. Go to General and then tap on About.
  3. Scroll down to find the Network and Operator settings.
  4. Network: This shows the currently active network if available.
  5. Operator: This displays the last network your iPhone used and is usually the network it is locked to.

2. Can I determine the network an unlocked iPhone was previously used on?

Yes, you can determine the network an unlocked iPhone was previously used on by checking the Operator setting in the About section of your iPhone’s settings. This will show the last network the iPhone was connected to or used. It’s important to note that unlocking your iPhone makes the primary carrier irrelevant for future use with different carriers. To confirm if your iPhone is locked to a specific network, try using a SIM card from another service provider. If it works, then the device is unlocked.
