Samsung Volt O2

I am a long term VM customer and have VO!T with an O2 SIM.             

I want to get a new Samsung Galaxy, but the deals on O2 are unrealistic in price.

I can get a deal through Samsung direct with an O2 contract attached at a very good price. 

If I give notice to O2, for my current Sim, under the 30 day price rise rule, will I lose Volt because my new contract is brokered through a 3rd party I.e., Samsung. I would appreciate a ruling from a member of the Forum Team.   Thanks
