DS now at age where he's shooting off with mates etc and is one of the few who does not have phone for emergencies etc. Any suggestions for reliable, simple phone that doesn't cost a fortune? Probably going for rolling monthly sim-only contract, versus 24-month one or PYG - so will end up buying phone at PYG rates. Re' tariff, looking at ones at moment that do 100 minutes, unlimited texts etc for about £10pm.
