The process is easy to follow. You can always check the progress of your IMEI unlock.
I waited around 10 days and now my iPhone is unlocked from KDDI Japan. I just restarted it with my old sim card (ATT Mexico) and is now working perfectly!
Thank you so much! Great service, worth every penny

Thanks for your service. my iPhone 5s is working good with other carrier sim. Unlocking process takes time about 8 to 10 days. But, factory unlock service requires time.

Japanese phone operators are notoriously protective of their hardware. This service was able to circumvent that, the service standard is high and professional.

My locked IPhone Now is unlocked and works with a new sim. Very very happy. It took longer and than expected With slightly high cost but with excellent customer support emails and follow up the unlock was delivered. Hopefully it'd stay unlocked as the company says it will. Have even ordered another unlock for my iPhone 6s. It's REAL and and Excellent service indeed and definitely not any fly by night operator.

It took 12 days. Finally my AU iPhone has been unlocked! Now I can say they offer safe and sure service. I am sure that the factory unlock is definitely the best choice comparing with using the sim unlock adapter which has major defects.

Realmente o serviço é muito bom. Recebi e-mails frequentes avisando sobre o andamento do desbloqueio. Recomendo muito tendo em vista que estava com um problemão e que resolveram com o desbloqueio do meu Iphone 5S 64gb bloqueado na Au Kddi.

At first, I was in doubt of providing my credit card. I have waited for almost 1 weeks the most, and even lost hope and didn't even mind checking my email if I got any email from the said site. I don't know what forced me to have the gut feeling to check my email, and VOILA! an email from saying that my request to unlock my iPhone 5g has been "MISSION ACCOMPLISHED". So my iPhone 5G which is locked from Japan Au KDDI before, now is working with my Philippine Sim "Globe Network". Thank you very much to this website, now I don't have to worry about replying to my contacts in a different / original phone number format.

I want to share my experience. As my iPhone carrier is KDDI, Japan, it is heard to find the unlock services. When I saw this website, I thought to give a trail. I did on September 7th, waited then suddenly on Sep 14, I got email that my iPhone is unlocked. So excited and next day I check with my colleague sim card. WOW !!! it worked nicely.

I recommend this guy.... You can trust...

Thank you very much..

For all those who are thinking about an unlock - Definitely this one WORKS. I totally recommend the service. They took a little more than 1 month to unlock my iPhone 5 here in Japan (and I thought it would be really tougher because Japan is a very strict country with hard rules and policies). It was still in contract with AU (what costed me higher - I had to make another payment) so that's the reason it took longer I think. The company contacted me and guided me keeping me updated on the status of my unlock. I contacted then 2 or 3 times and they replied me promptly with short but clear information. I have just received an email informing me about the unlock. I did not have the screen showing the unlock on the iTunes as they say/said but when I inserted a different SIM card it worked. It took a little to my iPhone understand the new card. I had no signal on the first 2 or 3 minutes but after 1 or 2 restarts everything went OK. Now I have my iPhone SIM free using a YMobile SIM card (I had to cut the SIM because they are different sizes - you can buy a cutter at Amazon or cut it yourself using very sharp scissors). My order was placed on November 3, 2014 and it was completed today December 9, 2014. TOTALLY SATISFIED....

All their procedures are transparent and their timelines are correct.. If you happen to have an issue with your unlock they will take time but still notify you in the end..

Truly the service works.. Takes time and i was impatient at first but when they came through i was glad and would do it again for next phone with no qualms this time.

Satisfied customer....... My phone had locked after an upgrade.... now factory unlocked.,

Thanks guys my iPhone 5 linked to KDDI, japan was unlocked (worldwide unlock service) however it took more than a month (18th July to 25th August).
The service is reliable but my only complain is communication and customer service. Its better that at the time of buying unlock you don't
offer this 24-72 hrs timeline to lure us. Moreover it would be very nice if you keep providing regular updates especially if the customer asks you
questions through the support page. Active communication really helps!

Ordered a worldwide unlocking service on a KDDI-Au locked iPhone 5 in late August, and unlocked within 2 weeks. Super fast service and genuine! Thank you very much! Might order again for another locked iPhone!

this is my third unlock with the company and they were able to unlock a locked KDDI Japan iPhone 4S. Took them less than a week and the cost was very reasonable. Great company, no doubt will do more business with them.

How to unlock iPhone 4, 4S, 5, 5C, 5S, 6, 6+, 6S, 6S+, SE, 7, 7+ locked to KDDI Japan

Step 1: Simply choose your model and enter your IMEI. KDDI Japan.

Step 2: The unlock price and timeframe will be displayed for an unlock for an iPhone locked to KDDI Japan 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 KDDI Japan 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).

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.
