SWMBO's mobile recently had an unfortunate and fatal meeting with a Toilet (rice trick didn't work) and she's in the market for a second-hand one while currently getting by with daughter's spare....
...but seeing as it actually gets used as a telephone, ie for voice calls,
I did have a look for a Review site that would allow me to key in specific requirements, but no luck.
Looking to spend £50-ish second-hand, eBay.
NB: in a similar vein, we noted while checking out one of the major network's deals that they appear to be less than honest about the monthly cost of the Hand Set. A 'Contract' deal for the requisite Data and Text allowances was approx £19 monthly, with £4 stated to be for the Handset and the rest for the Serivice....
...but the same provider would provide identical services, without the phone, 'Sim Only' for a tenner a month.
On a happier note, I just bought a top of the range Bosch S5 Battery for £80! ECP have a 50% deal, get there quick if you need one.
