Got a phone locked on t-mobile uk, how do I unlock it?

[riquier]

Got a nokia locked on t-mobile uk, when i put a sim from another network, it says restricted and tells me to input a code. 

when I write my imei number on the ee unlock website it keeps saying 'application error'

When i try an imei of another phone, it goes through just fine, what is going on? please help!!

Hi @riquier 

It is likely too old to be unlocked by EE if it is T-Mobile. 

I suggest looking on Google for solutions.

Thanks

But I had another phone locked on t-mobile and it unlocked on the website just fine, without any trouble!

Hi @riquier 

It could be that the device you're trying to unlock is too old, so we don't hold the codes for them any more, 

You can give Customer Service a call who'll raise a request to the unlocking team to check if there is a way to unlock the T-mobile device.
