From the press release:
O2 Broadband, through a wireless USB modem, will enable up to 10GB of data to be downloaded as standard per month, with no additional charges for occasional usage in excess of this. O2 is the first mobile provider in Ireland not to automatically charge customers if they exceed the 10GB usage limit, subject to fair usage policy.
The service will initially be available for a three month introductory price of €15 per month for those with an existing O2 post-pay voice connection or for new post-pay customers taking a voice connection*. It will be €20 for all other customers. Following the three month promotional period, the monthly cost is €30 (with voice connection*). For all other customers the cost is €40 per month. The USB modem will be priced from €69 (all prices quoted are inclusive of VAT).
I’ll be trialing it this week to see what it’s like. I’m going to try and get clarification on the “occasional usage” line.
Update: So basically 02 are saying, don’t ride the system and everything will be ok. If someone goes over they will be informed if they will be charged if they further go over the cap.
