How do I know if an iPhone is unlocked? 3 ways to find out
It’s very easy to check if an iPhone is unlocked or locked to a carrier with the above three quick and easy ways. You can check it through iPhone settings, using a second SIM card or with an instant iPhone Checker.
The first 2 methods require the physical presence of the iPhone so you can review its settings and test other SIM cards. The third method has the ability to tell if your iPhone is unlocked remotely (anywhere in the world).
The first 2 methods are completely free since all you have to do is to check the iPhone’s settings or test a few SIM-Cards. However, the third method is a paid iPhone Unlock Check service, since it needs to access non-public databases which require a small fee.
1 – How to tell if iPhone is unlocked without sim card – iOS Settings
Since many users are asking us how to find out if their iPhone is unlocked without using other SIM cards, we found this method that can show you if your iPhone is locked or unlocked (There is some margin of error though).
- (Step 1) Power ON your iPhone
- (Step 2) Tap on “Settings” and then go to “Cellular”
- If you can find the “Cellular Data Network” tab then most likely your iPhone is Unlocked
- If you do not see this option (The “Cellular Data Network”), then most likely your iPhone is Locked by a Mobile Network
- (Step 3) Power OFF your iPhone and eject the SIM-Card
- (Step 4) Re-do the whole process from Step 2
- If without the SIM-Card the “Cellular Data Network” is there, then there are high chances that your iPhone is Unlocked
Unfortunately, this method is not 100% accurate, because the presence of the “Cellular” option alone does not mean that it is definitely unlocked. However, its absence is very likely to mean that your iPhone is locked.
Another drawback of this method is that it can not tell you which provider the iPhone is locked to.
2 – How do you know if an iPhone is locked – Using 2 SIM Cards
With this method, you can definitely tell if your iPhone is locked or not.
It is a very simple method and requires at least 2 SIM cards (if you have more, even better!).
- (Step 1) Power OFF your iPhone
- (Step 2) Insert the first SIM-Card inside SIM-Tray (Use the appropriate tools to eject the SIM-Tray to be 100% sure that you will not damage it – Read Apple’s Guide on Switching SIM-Cards)
- (Step 3) Power ON your iPhone
- (Step 4) Check your iPhone’s Screen
- (Step i) If it shows a “SIM not supported” or “SIM Invalid” message, then your iPhone is Locked
- (Step ii) If you can normally access the Home Screen but you cannot make any phone calls, your iPhone might have a different kind of a lock (Maybe Blacklisted)
- (Step iii) If you can make phone calls, then this means that this SIM-Card it allowed (It is not 100% sure that your iPhone is Unlocked)
- (Step 5) Power OFF your iPhone again and insert the second SIM-Card
- (Step 6) Power ON your iPhone and check your iPhone’s Screen
- (Step i) If it shows again the “Step 4i” error codes, then your iPhone is definitely locked to a mobile network
- (Step ii) If you can access the Home Page but you cannot make any phone calls, then your iPhone is Unlocked for sure, but most likely it is Blacklisted
- (Step iii) If you can make phone calls, then your iPhone is Unlocked (At least inside the country you currently live in)
With this method, you can be 100% sure if your IPhone is locked, but not if it is unlocked for all carriers worldwide.
If you have other SIM cards in your possession, then you can try them too. If you are lucky and you find a SIM card that lets you make phone calls, then the provider of this SIM is also the lock carrier (The network in which that iPhone is locked to).
