Browsing the Internet on Happy DTAC GPRS can be painfully slow, but due to a recent house move I've had to use mobile internet more frequently on my phone. Several months ago I signed up for a recurring package of 20 hours per month (105 baht per month) but when I checked today I found I had run out of remaining minutes. No problem!

Thailand Mobile Expo 2010 is running until February 7 at the Queen Sirikit National Convention Center. Previous fairs have attracted large numbers of visitors – particularly at the weekends – and this year should be no exception. Most of the "bargains" (advertised in Thai) are strictly limited to the first few customers; nevertheless, the fair is a good place to see all the latest mobile phones, PDA and GPS devices, generally at high street or slightly discounted prices.
