I'm currently on a Three SIM only contract, but have broken my nexus 4 
I like the look of the LG G2 so I'm planning on getting one of those and Three is again my network of choice by some way due to free and unlimited 4G.
Included in the deal if you pre-order from Carphone Warehouse is one of these http://www.lg.com/ae/pocket-photo (worth around £100) which is a nice bonus.
However CPW don't do Three upgrades, and I'm not even sure I can upgrade from my SIM only to a 24 month full contract, as I've been with Three for less than 3 months.
So taking out a new Three contract looks the way to go, but obviously I can't port my number between two contracts within one network. So my question is, is it possible to port my number to (for example) a dirt cheap giff-gaff goodybag, then straight onto the new Three contract without any problems?
