Sin duda, liberar un iPhone por IMEI es la mejor opción para zafarse de las ataduras de las compañías de telefonía y de paso evitar tener que hacerle jailbreak al teléfono con el único objetivo de utilizarlo con otra compañía.
I have been an iPhone user since 2008 and I have always needed to jailbreak them because they were all unlocked by software, that is, in order to be used with any company I had to install the corresponding program to activate it (ultrasn0w) after each update of the phone’s firmware. At first there were no problems because, by the way, I could install from Cydia (and before, from its predecessor Installer.app) many system improvements, many of them essential.
However, today many of these essential improvements have already been included in the system itself and I consider that it is no longer worth the effort** of jailbreaking it.
So the other day I decided to take the step and unlock a couple of iPhones by IMEI. I had never unlocked an iPhone this way and I had doubts. Where do I do it? Will they damage my phone? The last history I had with Movistar was not good, so I was a little afraid.
Finally I opted for DoctorSim and for just over €20 I had two iPhones (An iPhone 3GS and an iPhone 4S) in less than 24 hours. The service they offer is already very good: you receive periodic notifications of the status of the process, they have an intuitive and very well designed page, but the customer service could also be considered an example of how to use social networks, in this case Twitter.
While I believe that there are many people who may find this article useful, it was the treatment received that led me to write this post. Demonstrating that behind a Twitter account there is a person with whom you can have a conversation and not a robot is a plus point that, against all logic, many companies do not understand.
If one day you find yourself in a situation like mine and want to unlock your iPhone by IMEI to save yourself the hassle of jailbreak and Ultrasn0w, I hope this post has been useful to you.
