I'm not sure what it was that
lured convinced me to buy a pre-paid AIS 3G SIM card, but much like the old guy on the right in this photo, I couldn't seem to help myself. In any case, after the leather-clad sales-girls let me use a "demo" sim card in my phone to make sure it worked - including a video-call made to another booth-girl on a different floor - I plunked down my 110 baht, plus 300 baht for 1.5 GB of data (over either EDGE or HSPA) for a pre-paid sim. AIS's 3G service runs on their 900 MHz spectrum, so definitely check with them to make sure your handset will work before signing up (I can confirm that HTC Diamonds
do work!).

AIS's prepaid brand is
1-2-call, and the sim-package was sporting a very happy-looking frog wearing a crown. No, I have no idea. Based on the frog's smile, he never leaves Central World though (more on that in a sec). After slipping the sim into my Touch Diamond, and booting up, WinMo helpfully told me that it needed to configure my phone for AIS (I normally use DTAC), after which (this IS Windows) it had to reboot. I had to manually change the "band" selection from "auto" to "WCDMA" for some reason - according to the AIS guy, their mini-cell-tower's software needs to be upgraded.

In keeping with the green animal motif, the plastic card has a picture of a green mouse riding a cheese-mobile. The so-called "Freedom sim" works on AIS's regular GSM network, with all its EDGE mediocrity, wherever 3G isn't up and running yet. That would be practically
everywhere. The only 3G coverage is provided by some sort of pico-cells, or mini-cells, in Central World Mall, Siam Paragon (another giant mall), and MBK (the grand-daddy of Bangkok malls), in addition to their original test network in Chiang Mai.
Oh - and the new airport (Suvarnabhumi), which is once again running after
recently being the subject of a sit-in by protestors.
The stupid thing about the current state of AIS's mini-cell locations is that all of them have WiFi coverage anyway - True Move offers WiFi (not free) in all of these places, which cost me 250 baht/month on a promotion.
I wrote about True recently when checking out a new store/cafe they opened. An AIS employee assured me, though, that the first "real" cell-towers will be upgraded to 3G starting next month, so I'll post back when there's any new info. Until then, though, if your phone has WiFi, you're better off with that.
The low-down on pricing is this: Video calls are 1 baht/minute. Not that therei s anybody to call, except the AIS demo-booth girls. Whether you sign up for a normal post-paid account, or get a pre-paid sim, you need to pick a data plan (since it's a baht per MB if you don't!). All the below are for monthly usage:
- 100 baht for 500 MB
- 300 baht for 1.5 GB
- 500 baht for 2.5 GB
- 900 baht for 15 GB
- 1,500 baht for 30 GB
If you're sucking down 30 GB per month, you clearly have a bittorrent problem and should be running that on your DSL at home, but otherwise the prices are not bad! 500 baht (about $14) for 2.5 GB of data is enough for a lot of web-surfing, youtubing, emails and general syncing to Exchange/Zimbra/Gmail or whatever. Google maps is fabulous over 3G,
as I discovered in Korea in September. I did a couple of speed-tests using DslReport's "
iPhone browser Speed and Latency Test". Given that I'm in Thailand, and the server is likely in the U.S., I was pretty happy with the 491 Kbps and 467 Kbps results in my two tries. It's no
4G WiMax, but it beats EDGE.
So. I don't really want to change phone numbers (no mobile-number-portability-act here!), so sometime in February or March, I'll see what DTAC is up to - if there's less than a 90-day lag before they roll out their service, I'll wait. Otherwise, I'll be back to see the AIS girls!*

Note - the girl who helped me with the demo admitted she was just hired part-time for this promotion. I asked her if she uses AIS, and she sheepishly admitted that no, she's using DTAC too. LOL.
