O2 contract - help

harriet.victoria

Hello

I have been on o2 for about 4 years now, always with a contract phone. My current contract ends in July (so not that long now) however, my current phone is completely useless. Every few days it deletes all my numbers and messages and decides to not be able to connect to the o2 network and sometimes even tells me that the phone has no battery in it when i try to put it on charge. I have a sony erricson C950.

Can anyone tell me whether I have a chance at calling O2 and asking to upgrade early due to the fact that my phone is so useless? Or will I literally have to wait until the last month?

Also, would anyone recommend letting phone 4 u buy me out so I can get a new phone that way? The only problem with that is I think that the monthly charge for insurance with phones 4 u is absolutely extortionate and would therefore like to keep my contract direct with O2.

Thanks for any help.
