Hi,\n\nI've owned a mobile phone for about 8 years; this phone cost an whole £5 new through eBay and it broke my heart to put on £10 credit; 8 years on I've now got £4.40 credit on it this after a first £10 top up; I only ever use the phone to let Bron know I'm on my way home from Rufforth Auto Jumble once each month weather permitting so perhaps only 9 times each year.\n\nJust to indicate how much I know about these mobile phones when I topped up with credit I topped up with Vodafone; I thought all was well until the money was refunded then I topped up with O2 and all was well.\n\nA few months ago I bought Bron her first mobile phone it being new and O2 just in case of emergencies. I put £20 credit on it. Bron used her phone once just to test it; this morning Bron asked how often she needed to use her phone and I thought it to be once every 3 months? Now when Bron tried to ring our landline her phone is absolutely useless bringing up a "Invalid sim" message so in an emergency Bron is expected to contact O2 first before using her new mobile phone? So much for modern technology in an emergency; a box of matches to light a fire sending smoke signals would prove more useful.\n\nI don't trust anything having a circuit board fitted and I dislike any phone with a passion; I used to have three desks one in each of my departments at work with five phones in total and I also had a pager; at times I would have three pagers when my colleagues were off site; the phones and pager/s used to drive me mad hence I now detest phones.\n\nOut of curiosity I've just browsed the web; I can contact O2 by phone hopefully to resolve the problem which would be highly useful stuck in a remote area in an emergency with a dead mobile phone.\n\nOK I'm a dinosaur and proud of it but I remember the days long ago when things bought were reliable especially "Made in Britain" We're visiting Meadowhall Shopping Centre tomorrow so we'll pop into O2 and ask them to get the jump leads out to bump start this useless phone.\n\nI've just been up the mountain with a very old very reliable hoe to do some weeding.\n\nModern technology; Bahhhhhhhhhhhhh.\n\nKind regards, Colin.
