How to Make a Locked iPhone Accept Any Sim
Happy with your iPhone, but think you are paying too much for data and text messaging? We’ve all there before, to be honest. Sometimes switching carriers is a good idea, but there can be a small downside: if your iPhone locked on a particular network, you’ll need to unlock it before it can accept another carrier’s SIM card.
If this sounds complicated, don’t worry. Below all the information about how to unblock cellular carriers. Remember that an operator lock different from a screen lock. The latter prevents you from accessing a phone, while carrier lock prevents you from using another carrier (if you have Verizon, you cannot use AT&T until the device unlocked).
Here’s how to tell if your(phone) iPhone is locked
There are several ways to know if your iPhone unlocked. Let’s go through the methods.
Use a SIM card
Not sure if your phone locked? Well, that’s pretty easy. Just take out your current SIM and try a new one from another provider. If you bought your iPhone directly from an Apple Store, it unlocked by default, so switching between SIM cards from different networks quick and easy, and you don’t even have to restart your phone.
But, if your iPhone locked, you will get error messages like “Invalid SIM” or “No SIM card installed.” This may not mean your phone locked; it could be an iOS attack. With this mount, it’s just a simple case of turning airplane mode on and off and rebooting the phone or reinserting the SIM card.
Alternatively, go to Settings | General | Info, and tap “Check for carrier settings update.”
Note: If possible (in the GSM network), it better to use a SIM card from T-Mobile or AT&T. Some CDMA phones require particular SIM cards, which vary depending on the phone model. This means that your mobile may be unlocked, but it won’t recognize the SIM card you have inserted.
Check with the carrier
Most cellular service providers have the option of verifying that your phone can be activated on their network. AT&T, for example, has this website. You can enter your phone’s IMEI number and get notified when it’s ready to be activated or even blocked with a previous carrier.
If you receive a message with the SIM card locked, you are out of luck and need to unlock your phone.
Find out if a phone is unlocked earlier than you buy it
A common problem with unlocked phones selling them to someone else. Whenever you buy a locked phone from the original purchaser, you must unlock it. You can, of course, check with your carrier to see if the IMEI supported, but this won’t continuously tell you if the phone unlocked.
The best thing to do meet with the seller at your operator’s store and activate the service before paying for it (most honest sellers will). However, if you buy the phone from eBay or ship it to you, it not an option.
Your next choice to use a third-party site to run the IMEI for you. But, as always, there risks here too. Most of these websites charge a fee, and some not even accurate. If you visit the original operator’s website, you may be in luck, but you will need the actual account number and other vital information that the seller may not want to give you.
What do I need to unlock my (phone) iPhone?
If you have received your phone under a contract, your phone will only be blocked from the network until the conditions of the agreement, rental, or installment payment met.
you bought your phone used, it a bit more complicated; you can’t get the seller to unlock it, you may have to go through some hurdles.
If the phone were originally purchased under a contract or lease, you would likely need the original account holder’s information to unlock the phone. Otherwise, the phone will stay with that provider forever.
