First, sorry for my bad english. I haven't found another forum where ask this question.
Supposedly, the Spanish carrier Movistar and Sony have reached an agreement whereby, we provide a way to allow unlocking bootloader (which is not the same to "unlock the bootloader". We want to our mobile indicates: "Bootloader unlock allowed: yes").
The problem is that Sony is not providing the solution to contact them by mail, as their community manager indicates in its Movistar official support forum.
If Sony is a reputable company, I wonder if they think to solve this problem, or they will follow in the footsteps of others such as HTC, making excuses not to meet various users' request.
Solved! Go to Solution.

I think there is a bit of a translation issue here. Can you reply in Spanish?
What model phone do you have?

Xtorm "talks" about the restriction that many people (who bought the phone through a phone company, in our cases, Movistar) aren´t able to use this: http://unlockbootloader.sonymobile.com/ because we have "Bootloader unlock allowed = NO", instead of "Bootloader unlock allowed = yes". That's right if you have permanence with your phone company but if you buy the phone without it or when the permanence ends, you have the right of having the phone as if you had bought it "free", without any phone company.
The problem has been talked with Movistar and according to them (you can see it in the link of Xtorm), Sony has accepted to provide us the way of getting the "Bootloader unlock allowed= YES", we only have to send an email to firstname.lastname@example.org with our IMEI number and the unlocking code (SimLock) which is given by Movistar.
However, the answer of Sony is not clear because, we know that what we need is only a code, like the SimLock code, but Sony sais that we have to send them our phones during 2 weeks to get the "Bootloader unlock allowed=YES". Besides, in some cases, Sony says that the code to unlock our Sim is wrong which is not possible because that code is given by our phone company.
We ask Sony to clarify the solution. We paid our phones and, as I wrote before, we haven't any permanence with Movistar, therefore we have the right to have our phones without any restriction. I hope you can understand our situation.

this is interesting, according to Sony
However, even if the phone model is supported, certain releases of the phone model may not be supported due to operator restrictions. To check if your phone can be unlocked, go through the first two steps on the page.
but according to movistar
Movistar desconocía la existencia de dicho bloqueo, y por tanto no ha sido una solicitud por nuestra parte, sino que como hemos indicado previamente, lo activa el fabricante ya que el desbloqueo del bootloader lógicamente reduce la seguridad del simlock.
Movistar was unaware of this blockade, and therefore has not been a request on our part, but as we have previously stated, is activated by the manufacturer and that unlocking the bootloader logically reduces the security of simlock.
something doesn't add up
