Before you will learn how to unlock iPhone in the UK for free and become free from your carrier you should first make sure that you are not unlocked already. Take any SIM card that doesn’t belong to your main network and insert it into your iPhone 6 or 5, 5S. Just remember that the iPhone 4S needs a MicroSIM which is bigger from what iPhone 6 Plus, 6, 5S, 5c and 5 need.
So once you are sure that you have a different SIM card [different from your mobile operator] and it is of the correct size, insert it into your SIM tray. Do you see the signal? If the signal appears you are fine and don’t even need to learn how to unlock iPhone 6 Vodafone, Virgin Mobile, O2 or any other carrier. If you are asked to insert a correct SIM or get a message about an invalid card or a card that can’t be accepted or there is no signal, you are locked to one network only.
How to Unlock O2 iPhone in the UK
We’ll add that it is simpler to unlock iPhone O2 UK by IMEI factory service, but we’ll still explain how you can do this directly from the carrier though it takes more time and is pretty expensive. This operator allows subscribers who are out of contract to fill an unlock form and pay either £15 [$23] or get the free unlock [which isn’t confirmed on the site].
You can give it a try and contact O2 to make sure you are eligible for direct unlocking service or just do the following thing. According to this carrier, non-O2 consumers can insert any SIM into their iPhone and connect to iTunes to become automatically unlocked. Give it a try, why not?
Just remember that you can unlock iPhone 5, 5S and earlier models through O2 and this carrier said that it had no plans for unlocking iPhone 6 Plus and 6 for a while.
How to Unlock iPhone Virgin Mobile UK [Tesco Mobile]
If you have a new smartphone that was bought recently from Virgin Mobile it has to be already unlocked. According to the carrier, any older iPhone units that were locked to this network can be unlocked automatically once you update your iOS to iOS 8.1.3 which is the latest official public version of mobile firmware for Apple smartphones.
Tesco Mobile agrees to unlock only iPhones that are out of contract. You can call 0345-301-4455 to order the service directly from this carrier but first find out how much it will cost you. Remember you can order factory IMEI unlock instead.
How to Unlock iPhone Vodafone UK
If you have a Vodafone account or know the information about your iPhone previous owner who had such an account you can order unlock directly from Vodafone. The carrier promises to respond to your request within 48 hours and unlock your smartphone within the next 10 days if you are eligible.
Users who had their Vodafone data plan for over 12 months can become unlocked for free, but everyone else has to pay £19.99 [$31].
