I have 3 batteries for the phone - all 10 years old - all work perfectly!!
Whats the problem??
Orange wanted to keep me at the end of the £99 for 12 months offer in 1996 - so, they put me on the Virgin Offer (to match Virgin) ...... this is where I simply pay for calls ONLY.
Hence the 35p a month average - 2 texts and a short phone call - picking up my voicemail is free too!!
Best deal then, best deal now

Why change??
