I HAVE ISSUES with O2-Ireland's standard billing fees for 3G broadband because if I use the service as my primary data connection, I exceed my allowance before half the month is finished.
I run both O2 and 3Ireland MiFi service in my daily routine and rack up at least 25 GB of data usage over the air. Once I use 15 GB with O2, any additional broadband usage costs an inordinate amount of money. As the screenshot shows, O2 charged me a fee equal to an entire month's broadband for two days of service.
Part of my O2 usage pattern is a tribute to the powerful upstreaming service offered by O2. The O2 mobile broadband service is well worth the contract but it simply is not fair to set power users up for bill shock because of a fee schedule that is designed to extract immense profit from known usage patterns.
