When 3 take over o2

[Anonymous]

Hi all.
just having a beer after work in the beer garden and got to wondering when 3 take over o2 how do they "unlock " your mobile phone so it can receive the 3 signal?
do they change the signal code somehow so your phone knows?
BT will do the same with ee too in time.
I think I should get out more! Lol
cheers

Heres a good thread by @Bambino for you to look over, the deal won't be complete for at least a year

It's all back door stuff - your phone won't change at all.

Example for you when O2 started all that changed was the name on people's mobile screens from btcellnet to O2-UK

@MI5 strange thing is all that stuff is back door and will allow you to use a 3 simcard in your existing phone but to do that now / previously  (without the change over) we have to request a unlock code and manual enter it e.c.t.

So technically speaking shouldnt that process be able to be back door aswell? 

Ik it's probly more complex but idk

Ya, is it a software thing ?

@Anonymous it will all be done in due course, do not get your knickers in a twist about a deal that is yet to be fully ratified

Not really getting in a twist, just asking a tech question about how they carriers switch the signal so the phone can receive it.

Any operator can make a change on their servers to allow any sim to be used on any network - Just like when you are roaming abroad for example.
