What's the highest your cellphone bill has ever been?

Don't have to worry about that when your using a pay as you go service. If you have no money on the cell then no texting or making calls out on the cell phone. Or receiving any. Mind you I always check to see how much I have before topping up on it. So It is always a small buffer of money on it. :-)

I pay every three months and the highest it's ever been on is €435. Though in Scandinavia there are ALOT of services you can pay by phone, so the highest actual bill I've ever got was €3,469.00 But of course only €60 or so was the regular texting, phone, internet use. The rest was mostly train tickets, flight tickets, donations and beer when at the pubs.

£10.................

I don't use the phone much. Email is free and I can talk to people over the seas with it.

never had a bill because i'm on pay as you go, and it's a real good company, it's 1p international calls! which is all i use it for, and my wife has the same sim and i get 100 free minutes to call anyone on the same network with each £5 topup.

never going to go onto a contract because of the charges.

and after reading this:

Women gets $200,000 bill http://www.dailymail.co.uk/news/article-2050717/My-life-Shock-200-000-roaming-charges-womans-brother-takes-phone-holiday.html

i dont think i ever will get a contract, well unless i see a real good deal, you can sometimes get free laptops or ps3's when you get some contracts, but the payments are too high.

$437.50

I forgot to turn off international roaming when on vacation in the Dominican.

$80 for 6 lines unlimited everything. Of course, I'm an employee so I get a special rate :P

247, because I forgot to switch out my normal sim card with the one I use for surfing the net.
