If you are currently seeing the irritating SIM Not Supported iPhone error screen, you already know that you can’t make and receive calls or send text messages.
Depending on the iOS version, this message may also be
- SIM Not Valid
- SIM Card Νot Ιnstalled
- Invalid SIM
Whether it’s because of a mobile network or not, the iPhone is locked until you find the problem and of course, resolve it.
What does SIM Not Supported mean?
Okay, the story goes like this:
You recently bought a used iPhone and the one who sold it promised that the iPhone is unlocked. However, once you have inserted your SIM card, you received the following message.
Before you start cursing the seller, we’ll have to take a look at what’s really going on with your iDevice. Why do you get SIM Not Valid?
The first question that needs a definitive answer and at the same time is a complete game-changer is the SIM Lock Status.
How to fix SIM Not Valid on a locked iPhone
Just by taking a look into various carrier forums, unlocking the SIM sounds impossible.
And the list could go on forever…
Of course, all mobile networks are suggesting that you use their services, but we all know that they are unlikely to do us the favor.
You do not have anything to lose, however, because their SIM not Supported Bypass Services are free or for a small amount of money.
But the point is: Do you know which Carrier has your iPhone locked?
The situation becomes more complex. Especially in the case of used devices, problems such as blacklist, outstanding financial balances, or an active contract make it impossible to use the unlock services of any wireless network.
So, we will need a third-party IMEI Unlock Service to fix SIM Not Valid.
However, there are new questions added on the table:
- Which service is suitable for you?
- Does your iPhone fulfills the necessary requirements to use a service
- Is the service currently active?
Once again a SIM Not Supported Bypass Check will give you the opportunity to learn your phone’s status accurately in just a few minutes, but at the same time, iPhone unlock specialists will get you the most appropriate SIM Not Supported Bypass service for your case.
iPhone SIM Not Supported - 6 ways to bypass Invalid SIM iPhone screen when it is unlocked
Frequently the solution is much simpler than you think because your iPhone is not locked. If you know that it is indeed locked, then our free iPhone Unlock guide is something that will interest you!.
If your iPhone isn’t actually locked by a network, follow the steps below and maybe you will put the error screen behind you in just a few minutes.
You can check the following guide if you already know that your iPhone is SIM locked.
1. Make Sure the SIM Card is Active and Works
As obvious as it may sound, remove the SIM card from the SIM tray, and then reinsert it. Make sure the SIM holder closes correctly. Sometimes using a card from a different iPhone model or another smartphone manufacturer can cause the Invalid SIM Card issue.
Make sure the SIM card that you inserted is still active with your mobile network. Contact your Carrier and check for activation or network problems. You may need to replace your current SIM card.
Try using another SIM card. Perhaps the one you already used causes the issue. After all, messages such as “SIM Not Valid” appear when a SIM card is damaged.
Finally, if until recently another SIM card was used with this iPhone (even if its contract expired), the iPhone may need this particular SIM card to get activated.
2. Restart the iPhone
4. Make an Emergency Call
Return to the activation screen, press the Home button and select Emergency Call (911 in the United States or any similar number depending on the country you are living) and disconnect the call as soon as it is connected and tap the Power button.
If this trick is successful then you will be transferred to the main screen of your iPhone, successfully bypassing the SIM not supported error screen.
5. Update your iPhone to the latest version of iOS
If you are using a cellular data connection, try connecting to a Wi-Fi network (you know it is reliable). If the Wifi connection fails, try connecting to iTunes.
6. Use iTunes
Make sure that iTunes is updated to the latest version.
Open iTunes on your computer and connect your iPhone
- If “Set up as New” or “Restore from Backup” show up then iTunes activated your iPhone and SIM Not Supported is history.
- If iTunes says that the SIM card isn’t compatible instead, then you can try using recovery mode and restore your iPhone
If none of the suggested SIM Not Valid solutions worked then your iPhone is definitely locked.
Conclusion on iPhone SIM Not Supported
SIM Not Supported can be fixed regardless of whether your iPhone is locked or not. The only difference is that in the first case it is surely free but in the second case no (unless you do so through a mobile network).
The real problem is to locate the source of the SIM Not Valid issue.
