Making a quick switch is one of the quickest ways to check your iPhone's carrier. Go to Settings › General › About and scroll down to the Carrier field. It displays the network your phone is currently locked to or using, which is especially handy right after you insert a new SIM card to ensure everything connected properly.
Another easy option is dialing *#06# to retrieve your IMEI, then visiting your carrier's website to input that number. This free lookup tells you exactly which network owns the device. It works whether your phone is active or powered off, making it a go-to trick for people buying second-hand.
If your iPhone is unlocked, insert a SIM from a different carrier and open the Settings app. Under "Cellular," the carrier name will update in real time. This is super useful for travelers wanting to test a local plan before committing to a long-term contract abroad.
