I have written them many times. I have opened trouble Tickets. I have chatted with their staff and still my phone is not unlocked and unusable. They keep saying 2 or 3 more days. But it never happens. They have taken my money as well. I have been forced to file a fraudulent charge With my bank. DO NOT USE THIS CONPANY!!!

This company is a junk. They don't seem to have any clue about T-Mobile devices. I requested for my T-Mobile phone to be unlocked and they debited my account $23.95. After about 24 hours, they said my device is unlocked and sent me one useless code. According to their instructions, I should insert a sim different from the original sim after which I would be prompted to enter a code. I did that but the phone never asked for a code. Apparently, every person with a knowledge of T-Mobile devices know latest T-Mobile devices don't prompt for any unlock code. Instead, all unlocks are done through the T-Mobile device unlock app. To cut the story short, they took my money and didn't unlock my phone. After almost a month of trial with no positive result, they are now accusing me of using a wrong method. So please, don't waste your time and money with them. 

Im disapointed cause i order my code yesterday at 16:42 and pais for express service wich i should get between 1-12 hours,and i still didnt get it, i will change my review if you fox this...

The code they provided did not work and instead actually locked my phone for good. They refused to refund me, despite all the promises they make on their website. I followed the method to the letter and this company has left my phone useless, really not impressed!

Well I have order 7 unlock code of blackberry phone 4 works 3 don't. I have lost £8.85

I payed 28 dollars to get unlocked. Found out I had to sound 100 dollars more to get a mother special unlock. Support was bad. Computer responses to questions. With no refund.

I follow all instruction however the unlock doesn't work in my cellphone, I understand that I bought the imei unlock code under my own risk, but didn't work for me.

I ordered an unlock code for a Nokia 113 but the code send by doctor SIM is incorrect. Have emailed customer services twice with required information and still no response a week since payment was made. This company has very poor customer service and would not recommend DoctorSIM to anyone.

I have paid you 116 CAD, but you not resolve my iphone 6 anything, my iphone 6 is locked & it into lost mode, its icloud account has been locked & could not reactive it, since I had lost my iphone 6 icloud account information, so I can't active my iphone 6 through apple store, nor apple icloud account support, I must reactive my iphone 6 by icloud bypass or icloud unlock tools, that is why I have paid money to buy icloud bypass or icloud unlock tools, you said you have tools, so I have paid money, but you don't offer me tools, itune is totally useless for my iphone 6, because my iphone 6 iOS must need my icloud account information to reactive, but I had lost all information of my icloud account, so that the key problem is I must have an effective iphone 6 icloud account unlock or bypass tool, that is why I ask you offer me the software tools, if you have tools, just offer it to me , if you don't have any tool, then you have return my money, I'll look for other people. ok?

I have ordered code for my HTC but code send by doctor SIM is fake and doesn't work. My money has been looted by doctor SIM.

I was totally disappointed. I felt that I'd paid over thirty pound just to do the job myself. And it didn't work. I followed the instruction to the letter and my phone was still locked A complete waste of money

La menor decirles que mi teléfono Sansung Galaxi j7 2016 continúa en las mismas condiciones,ya he intentado todas las instrucciones que ustedes me han dado y todo intento de desbloqueo ha sido en vano.

When I placed the order online, it said 2 two days and 3 hours of the time frame. I called customer service on the third day, not only she was rude but also had loud background Foreigner TV sound that I can hear clearly. I asked when will my order be ready and she said within 30 days, then she hung up on me right after she said that. Worst customer service ever! I wish I went somewhere else!

Hace mas de un mes que compre un paquete para liberar mi telefono, despues de un dia de realizar la compra me informaron que no existia numero para mi celular y que si deseaba el reembolso de mi dinero, lo cual les indique que si que me devolvieran mi dinero, hasta ahi todo bien, me dijeron que en 24 hrs estaria el deposito y que lo veria reflejado de 5 a 7 dias habiles, pues asaron los 7 dias habiles y no hubo reembolso, me comunique por correo a el servicio a cliente y me dijeron que tenia que esperar 10 dias mas, pues pasaron los 10 dias mas y no hubo reembolso, me comunique de nuevo y me dijeron que ya no era problema de ellos sino de mi banco, que lo resolviera mi banco, hable a mi banco y me dijeron que no habia reembolso alguno por parte de la empresa y el cobro por el servicio seguia reflejado en la cuenta de doctor sim, pues nuevamente me comunico a doctor sim y ya no hubo respuesta, por mas correos que he enviado, son una estafa, confie en la empresa por todas las buenas opiniones que lei, pero LA REALIDAD ES QUE ME ROBARON Y SE QUEDARON MI DINERO, NUNCA NOTE POR PARTE DEL EQUIPO DE DOCTOR SIM, UN DESEO POR RESOLVER MI PROBLEMATICA, ME DIERON LARGAS Y AL FINAL DEJARON DE RESPONDER MIS CORREOS Y NUNCA ME DEVOLVIERON MI DINERO. A SIDO UN HORRIBLE EXPERIENCIA, NO LOS RECOMIENDO EN LO MAS MINIMO

The password i was given didn't work, it was a waste of money

It didn't work. Ended up having to get no Sim and phone number. Js

I expected the phone to be unlocked, not just get instructions to get a non Verizon SIM card. Waste of $29.95
