Unlock iPhone 4
Official and permanent IMEI-based unlocking service for iPhone 4
Step 1: Submit your IMEI
With our direct connection to all the manufacturer databases, we instantly detect your phone model and network using just your IMEI number. No other unlock company can do this.
Step 2: We whitelist your IMEI
We mark your IMEI as unlocked in your manufacturer's database which is then synced with your network. This typically takes a few hours. You can continue to use your phone as normal during this time.
Step 3: Unlock your phone
We'll then email you to inform you that phone is unlocked - some manufacturers such as Samsung will require you to enter a code whilst others such as Apple will unlock immediately over-the-air using your Wifi or mobile data connection.
When you unlock iPhone 4, 4S from its network, you open your device to a wide range of experiences with SIMs from other carriers. The benefits are many, but so are the risks, and this is something you need to be aware of before you approach anyone to unlock your iPhone 4, 4S from the carrier it is currently locked to.
The risks of doing an illegitimate unlock for any iOS device are considerable. For example, doing a software unlock for your iPhone using a method similar to jailbreaking may not be considered as legal, but it can end up bricking your device and rendering it permanently unusable. Another ill-advised method is hardware unlocking, which involves modifying your iPhones internals to allow other SIMs to be used in the device. The risk here is permanent damage to your device, which is certainly not worth taking.

Legal Way to Unlock iPhone 4, 4S
The only legal way to unlock iPhone 4, 4S from its carrier’s restrictions is to apply for an IMEI whitelist for your device. You can do that with the carrier, but it involves extensive paperwork and could put you out of pocket several hundred pounds in the process. The more affordable and quicker way is to approach an online unlock service provider like IMEINow.com, which is certified and authorized to offer such services.
You must understand that whitelisting your device’s IMEI can't be done by just anyone. IMEINow.com has privileged access to modify the status of your SIM and device from locked to unlocked. This will allow you to use another SIM of your choice, either from a different carrier or one from a local carrier when you travel overseas.

Our digital presence spans multiple countries and we are honoured to be granted privileged access with all the biggest mobile service providers on the planet.

Simply check your IMEI status on our website and then apply for an iPhone unlock for your iPhone 4, 4S and, in just a few days, you could be holding a legally and permanently unlocked device in your hands. Beware of unscrupulous websites that offer free or cheap unlocking services, because they could end up taking your money and leaving your device exactly as it was before; worse, they’ll tell you it’s free but steal your device details for nefarious purposes. Only use a trusted unlock service provider for iPhone such as IMEINow.com, and rest assured that we deliver on our commitment just as we have delivered to our million-plus customers - and counting.
