Unlock T-Mobile UK iPhone

  1. VERY IMPORTANT: This service supports all ESN - excluding Bad, unclean and Lost and Stolen

    This unlocks the GSM portion of the handset for international use. If you are based in the USA, it will still have to be used on Verizon(it won't work on AT&T for example).

Supported Models

iPhone 2G

iPhone 3G

iPhone 4

iPhone 4S

iPhone 5

iPhone 5S

iPhone 5C

Get started and enter your IMEI and Model

Your IMEI number is a 15-digit number unique to your handset. You can find your IMEI number in the Settings > General > About screen, or by dialling *#06#

If you cannot access this screen and you have an iPhone 4 or 4S then simply eject the sim tray on your iPhone. The IMEI will be printed on the sim tray - but please be aware that sim trays are sometimes switched.

If you have an iPhone 5, 5C, or 5S, the IMEI will be printed on the back of the iPhone itself.

Unlock possible - we can unlock this handset on all basebands, up to and including firmware 4.2.1.

i was afraid of doing it by internet and i try it... they unlock my iphone 4s in 3 days.. the always are in touch with you sending you e mails,, nothing to said just good service.

Muy buen servicio, estaba un poco temeroso de desbloquiar mi equipo por internet pero trate y resulto genial, solo se demoraron 3 dias en desbloquear el iphone 4s.
Te mantienen informado sobre el proceso en que va el desbloqueo mediante mails.

solo les falta mas claridad en los precios de desbloqueo pero todo el resto muy bien.

Enquired about getting an iphone 4 T-Mobile unlocked, responded quickly to my enquiry and phone unlocked with clear instructions using iTunes.
Iphone unlocked and I should of used OfficialiphoneUnlock a long time ago.
Everything that was required was met with excellence.
Highly recommended, don't bother about the high street places that claim to unlock just visit OfficialiphoneUnlock.
Will definitely use again.

I have used other services to try an unlock my Iphone 4, but they have all failed to deliver. So, I found out about Official iphone unlock, and they lived up to everything they said they could do. My iphone was unlocked from T-Mobile UK as promised and fast! I would recommend them to anyone.
Great Service, keep up the good work!!!

At first I was kinda hesitant of this site because it might be a scam .Before I paid for the service I made some research about the site to see if it's legit.Then found it 100% legit and decided to have their service unlock my T-Mobile UK iPhone.I was also worried about some delays in unlocking my phone because I have read some comment about it.But I didn't expect my phone will be unlocked in just 3days.They didn't exceed with the time frame they gave me.So happy and satisfied about the service. :))))

I had an iphone 4S, firmware 5.1.1, baseband 2.0.12, locked to T-Mobile and I live in Greece so wanted to use a Greek sim (of course). Spent hours scouring the web for a solution to no avail. Was about to gift it to someone as an expensive door stop when I found Sceptically gave them my IMEI and fifty quid and after a few days I get an email saying its unlocked. Naaahhhhhh, still couldn't believe it.......I am now holding in my hands an unlocked iphone 4S!!! Great customer service, quick replies to queries and honest. YAAAAAYYYYYY!

I came across this company online and spent some time checking them out and comparing it with others. I was very skeptical about it at first especially after I could not send the money directly using my debit card and they do not have a Paypal account which I think they should so people can be more at ease and to make it worse, I am located in the Islands of Cape Verde, est Africa.But anyway I sent the money transfer through my bank and was eager to get unlocked from T-Mobile UK. But 1st I had to be very patient since it took a few days for the money to be cleared, then another 24 hours for them to get the response from Apple servers. I sent the money on Tuesday, it was recieved on Thursday and I received the e-mail telling me that I was unlocked on Saturday morning (a week-end, mind you). That's why I feel nothing but pure joy joy joy, because these folks are real and they take care of their customers. I was even so happy to know from the web designer, that the concept for the site was done in Cape Verde when he came here on vacation months ago. Well folks, there you have it. I trust them totally and I will do business with them again and will tell all my friends about them. Thank you again for this new found freedom for my Iphone.

My iPhone Unlocked in about three days ... but there was some weekend time involved.

Ordered unlock in November 2012 but as T-Mobile and Orange were joining companies
it took untill 14 December to send order to Apple,It then took until 11 January to receive
unlock code. I telephoned the help desk and although they were very helpful they were
unable to advise a time from Apple.To be fair most of the delays have been due to
T-Mobile/Orange.and Christmes holiday shut downs.
The price was unexpectedly high but the phone had to be unlocked as it was a
Cristmas present.

iPhone 5 locked to T-Mobile UK successfully unlocked and registered back to me with Apple. Not the cheapest but service delivered as stated. I would advise any prospective customer to read the information on the website. My unlock took a few weeks but the reason was explained within the pages of the website. I am satisfied that I got exactly what I paid for. Many thanks.

After having phone pinched at work, had to get hubby's old iphone unlocked, Was really pleased that we found a trusted site to unlock phone safely. Took a little longer than I anticipated, as lots of the reviews said only took few hours, e.t.c. But it works, and can't recommend this site enough, as it really is safe.

Permanent IMEI unlock for T-Mobile UK iPhones (3GS, 4, 4S, 5, 5C, 5S)

Factory iPhone MEI Unlock for iPhones locked to T-Mobile UK. Unlock your iPhone with a factory IMEI unlock and make your iPhone sim-free. Supports all baseband and firmwares including the latest iOS 7 and beyond.

Your iPhone is permanently unlocked and will remain so on updates with iTunes as it is an official unlock.

Get your iPhone locked to T-Mobile UK working on your network of choice.

Our service is performed from the comfort of your own home. NO jailbreak hacking of your iPhone is required. Using our T-Mobile UK-approved IMEI unlock, your warranty remains intact and your iPhone simply becomes a factory unlocked unit.

Prices starting at £89.99

How to unlock iPhone 4, 4S, 5, 5C, 5S locked to T-Mobile UK

Step 1: Simply enter your IMEI on the Buy Now page - using our direct connection to Apple we will tell you instantly what carrier your handset is locked to and whether it is locked to T-Mobile UK.

Step 2: The unlock price and timeframe will be displayed for an unlock for an iPhone locked to T-Mobile UK and you simply enter your email address (for the unlock notification when done) and enter your credit/debit card details.

Step 3: Once we have marked your iPhone as unlocked from T-Mobile UK we will send you an email, containing easy to use instructions on how to carry out the unlock - it's literally as simple as plugging your iPhone into your computer and iTunes will display a message telling you that your iPhone is now unlocked (see below). Alternatively, if you already have service on your iPhone locked to T-Mobile UK or have access to a WiFi network, the unlock will be applied automatically Over The Air.

How we are different from the crowd

  • INSTANT carrier checking - never buy the wrong unlock again - other sites make you wait hours if not days if you choose to check your carrier first, and also will refuse to refund if you choose the wrong network when purchasing an unlock. However with just your IMEI we give you everything you need - guaranteeing you are purchasing the correct product. We take the guessing out of unlocking.
  • The fastest unlock delivery (check the reviews!)
  • Telephone support which is actually answered rather than a recorded message going nowhere. Remember we aren't robots though and don't work 24/7 - please call us during UK working hours Monday to Friday.
  • Status of your unlock is updated hourly, from submission right through to unlocking.
