I agree with most that 2-3Gb is a reasonable amount, I haven't (for the last several months) gone over the 500Mb soft-limit, but since the other day I have started using 3G a lot more (got the SureSignal) and 3G coverage is a lot stronger in my area lately. I hope I can get covered under this net of 10% because Vodafone has overcharged me a lot for many things in the past. Does anyone know if the 10% is for a specific contract or the account? I'm assuming it is for each individual contract? Will watch this closely!
