How To Know If An iPhone Is Unlocked or Locked

This article explains how you can check if an iPhone is unlocked, or locked to a specific cellular network. The difference is that an unlocked iPhone can be used on any network (like, only on Verizon, T Mobile, Sprint, etc.) while a locked iPhone can only be used only on the carrier it’s locked to. For example, a Verizon iPhone may be “locked” to work exclusively on the Verizon network and it cannot be activated on a competing carrier’s network. This is also called “SIM lock”.

Cellular carriers install software on the iPhone to lock it to their network. Unlocking involves disabling this software. This way, by locking, carriers are able to offer subsidized devices. This is why unlocked iPhones are worth more money. This may be especially important if you plan to buy a used iPhone because if you are not careful your new iPhone may not work on your cell carrier.

  1. My phone is Simple mobile from Walmart. iPhone XR. I had a replacement under warranty. From Apple. The phone says Carrier locked in settings and appears to have transferred all the data from the other, ie: shows the date when the original was purchased in settings but obviously this new phone has a different serial number. I am able to use AT&T and possibly other sims in this phone. What does this mean ?

  2. I have sim with H2owirelees, I transfer # to Ultramobile. My new sim dosen’t work then I found that I got sim lock. I call them. They say that they can not do do any unlocked because account gone. Anything over. How can i unlock sim.
