Has to be sim free. It will be a work phone and they provide a sim card and then money towards a handset.
I've seen it for £199, which makes £104 as an upgrade on a contract look rather expensive tbh...
Sorry should have mentioned that is an upgrade on PAYG and not contract. I have a T Mobile PAYG sim on my spare phone which I used to get the discounted price of £109 as a upgrade and I use my giffgaff sim in it which is my main number. Basically your paying £109 for essentially a sim free phone. Hope that makes sense.
They do not normally come sealed. Must have just been done by the place he got his from.
Cheers for the heads up.
