Today's gem on my other favourite website.
Not only going abroad ( a £400 bill was run up by a 13yr old in dd2 year on a school trip) but the money sink that is spam texts that you " subscribe" to, or your mate sign up to...or lend / mislay it overnight ( umm left it my locker mum) to find is been used for sex chat / calls to far flung lands. Etc etc
A nice phone in the hands of a little kid is a mugger magnet too.
And most insurance only cover the phone in the personal pisession of the bill payer anyway.
I won't even mention cyber bullying, sexting, porn or all the other things our little darlings would never ever get involved in but actually crop surprisingly often on mumsnet with kids and mobiles.
Mine have fairly basic phones ( the 16yr old does Use his on wifi at home. The 13 yr I'd has no phone Internet access) and giffgaff £5/ month unlimited txt sims.
If Å·ou must get a contract, or already have one, get it caped it you can, and block with the network, premium texts / numbers and data roaming if ou can gt them to agree.
