Makes sense to hold back on rollout
Considering the bloody mess that the mobile phone companies got themselves into, paying a combined £22.5bn for their 3G licences, it makes sense to hold back.
Let a few other countries determine the business model and iron out the kinks before we go down that road.
No-one, except a handful of companies, wanted to pay several £££ per MB of data. So the mocos in the UK had masses of unused bandwidth and big debts to pay off after they bought their licences. Once they went flat rate, data usage rocketed such that 3G networks now congestion and slow speeds.
The mobile companies had forked out so much money, they were forced to make it back with higher contract fees and call charges. Phone subsidies are not the only reason they're moving to 18 and 24 month contracts.
So for a change, let's not be the guinea pigs with a new technology. Once they've figured out what the demand for bandwidth will be, based on other markets, they can make an educated bid for some spectrum, without hobbling the entire industry from the outset.
