Numerous wireless service providers may be found in every region of the world. You must insert a SIM card into your mobile handset to access their respective networks.

What it means to have no sim restrictions

If you’re unfamiliar with iPhones and are wondering what no sim restrictions means, be assured that it merely indicates that the iPhone is unlocked and will accept a sim card from any network provider. The phone is not linked to a single carrier, so you may change the SIM card in it freely without worrying about whether or not the new card will function.

How Can I Tell If My Phone Is Unlocked?

Testing several SIM cards from different providers is the surest method to determine whether your phone is unlocked. A SIM not supported notice will appear in the screen’s upper-right corner if your phone is locked, often near the signal indicator. If there are no SIM limitations, but the phone still won’t function, resetting the network settings may help. 

In such a case, you should contact your mobile service provider. If you don’t have a SIM card but are curious about your phone’s network or locking status, you may do it by entering the settings.
