HSDPA Coverage
Talkback In Southbank I manage to get HSDPA coverage for my T-mobile dongle. Not run speedtests but have downloaded files at around 250-300kb/s T-mobile's £10/month then £15 a month after that offer seems to be better value.

3G operators bullish on coverage plans
Talkback I can't help wondering how "coverage" is measured. I have a 3 phone, which has been nothing but trouble as far as coverage is concerned for ordinary calls, yet alone 3g. What is needed is some form of standard to determine how "coverage" is measured.

Northern Ireland to roll out universal broadband coverage
Talkback 100% coverage! You must be joking. I am living in a new development on the outskirts of Belfast (Dunmurry), yet BT still cannot offer me a braodband facility. My exchange is Balmoral so I am too far away.
