Unlock vs Bypass Apple iPhone & iPad


Unlock is the process of ‘untying’ the mobile phone from the operator, allowing you to work with SIM-cards of any cellular operators. The unlocking is necessary if your iPhone was purchased with a specific mobile phone operator contract (usually phones purchased in the US), but you want to use the SIM card of another operator.

IMEI of all ever-sold iPhones are stored in a single activation database on Apple servers. Only Apple employees and representatives of mobile operators, who have an agreement with Apple to sell locked iPhones, have access to this base. This database contains information for each iPhone about whether it is locked, if so, on which mobile phone operator.

When you first turn on iPhone or do firmware recovery or update, the device send activated ticket. iTunes sends several hardware identifiers to Apple activation server. The server finds your iPhone in Apple activation database and sends an activation token in response, which encrypts iTunes instruction to allow iPhone unlocking for one or for any cellular operators.


What is bypass? Is it the same process as unlock? Have to say that they are absolutely different things. When you unlock some restrictions – you fully remove them. They could not appear again. But when you bypass something, for example MDM configuration profile, you just pass over it, not fully delete it from your device.

Imagine that you have to pull out a weed. You can root it away, and this will be Unlock. And you also can pull it out leaving small part in the ground. And that is what Bypass means.

It does not mean that bypass is useless thing! There is a big range of cases, when Unlock is Impossible and only Bypass can save your device from coma.

How to bypass MDM Lock (corporate devices)

How to bypass SIM Lock

You can buy Apple devices for bargain prices at online auctions. However, you need to be careful, because very often they are simlocked. You should also remember that when buying a phone you can get not only simlocked phone, but also this device can be reported as stolen or even with iCloud Activation lock, which won’t allow you to unlock the phone without entering the user’s password.

SIM-lock means that the phone has a software restriction on the mobile phone work. Sim-locked device can only work in one network. The customer who bought the SIM-locked phone from a certain operator could not switch to another GSM network. Such phones are usually sold by the operator for 10-20% of their real value, and the rest of the cost is paid by the operator. The purpose of such actions is simple: a SIM-locked phone will always remain working only in one network and sooner or later will pay back that part of invested money to operator.

SIM Locked Screen

Still, there are some ways to bypass Sim Lock. These include accessories such as R-SIM type card. After placing R-SIM in the phone, the lock becomes deactivated.

Such cards work with most iPhone models and on most cellular networks, and their cost is much cheaper than a full-fledged unlock. Unfortunately, this is not a reliable solution. After using old generation of this card, there could be a problem with 3G network support.

The biggest problem is that R-SIM cards can stop working after each, even the slightest update of iOS system.

How to unlock MDM Lock

How to unlock iPhone SIM Lock

What is SIM lock (Carrier lock)? When your iPhone does not accept your SIM card or when it throws an error message ‘this sim card is not supported’, ‘No service’ that means your device has SIM lock.

SIM Unlock is the process of unlocking Apple iPhone from operator for the future use of SIM cards of any country in the world. Unlock is required since iPhones in many countries are sold initially locked to SIM cards of a specific operator.

The server finds your iPhone in Apple activation database and sends the required activation token, in which, in fact, iPhone lock status data is encrypted. Whether it is blocked by the mobile operator (SIM Lock Status: Locked) or unlocked (SIM Lock Status: Unlocked).

If you switch on iPhone for the first time and see the message ‘SIM-card is invalid’, this clearly indicates that iPhone is locked to the mobile operator and your SIM is not suitable to complete the activation process. It is necessary to insert the SIM card of the operator with which iPhone was sold.

SIM Locked

Official unlock – iPhone lock status changing to “UNLOCKED” in the activation database on Apple servers. Apple Corporation has provided the opportunity for cellular operators to regulate this issue with their subscribers themselves. If the contract term, with which iPhone was bought, expired and there is no debt on it, the devices are UNLOCKED without difficulty. Just go to the official website of your operator and in the appropriate section apply for iPhone official unblock. This way you can make iPhone unlock in many mobile companies.

Also you can find many sites with offers for unlock simlock for various phone models on the Internet.

The authors of such proposals promise to unlock iPhone Sim lock on Apple servers, so that the lock will not return after software update. The cost of such a service varies depending on the model and network from a few tens to several hundred dollars.
