ZDBox is a great app for keeping tabs on your data.
It also has the an apps to SD, app lock, task killer, system cleaner and a few more bits and bobs.
Psst. It's free BTW.
^ it's typical Thailand really; once you've been through it once and know what you're doing then it is easy, but along the way will be misinformation and smiles and mai pen rai/dai instead of clear knowledge based advice...
That's why this forum works well - people learn by reading these threads, so they don't have to suffer themselves; the next person who buys an Xperia and wants 3G will know to bypass Dtac and go for AIS. At least I think that's right, I will know by the weekend once I've been to the Sony shop and AIS.![]()
Cycling should be banned!!!

I'm curious myself what you find out.
It reminds me of my xperience (haha!) getting 3G service, with AIS initially telling me about their "modern 3G service", and finally had to admit that 3G coverage in Bangkok is limited to, essentially, right outside the AIS store and about 100 meters around SIAM Paragon, and Central World - if you're lucky. They had no service to talk of.
TRUE, on the other hand, at least at their SIAM flagship store, was immediately able to tell me their exact coverage. I signed up with TRUE, and haven't regretted it - I used to have AIS for the 5 years preceding it. Haven't gone back.
I did switch to DTAC in Chiang Mai for a while, they basically had free GPRS on PAYG, and 12Call had nothing. Then they stopped it.
Now the 12Call 3G on PAYG works fine for me.
mostly use wifi, so I want a wide Bangkok coverage for 3G, not sure if AIS can provide this - we will see...

^ True Move has great coverage, plus you can use their mobile wifi hotspots, of which they have many, even down here, for free
They are on the same band as AIS too...
900

Don't waste your time and money on AIS, then - just get a TRUEmove SIM. I think they only allow new sign-ups on their TRUEmove H service, nowadays, which might be supported by your phone.
Again, I have had great support from their stores, so just go and ask. Seriously, don't waste your time with AIS.

I'm sure you can decide for yourself.

Plus, bear in mind that TRUE has nearly ubiquitous wifi hotspots citywide. Once registered, hand-over between hotspots is seamless. Works really well to give you decent speed, and conserve your 3G. AIS as no such hotspot network.
your advice is sh1t
any idiot who listens to you deserves what they get
I'll check both out, not sure if True do 900 or 850 like Dtac - I will just go to the shop and wait around until I see 3G on my notice bar (or whatever it's called).
As long as the missus let's me, I can.Originally Posted by harrybarracuda
Thank you.
It is also amazing how much misinformation and utter BS is written up to these forums.
For 3G frequencies:
AIS is 900
True is 850
DTAC is 850
TOT actually has 2100 which they sell themselves and via few virtual operators. The thing here is that it's ok for data but not good for calls and texts. They do not have any indoor coverage in malls etc so it's good for laptops with dongles only.
Coverage wise all of them have been expanding a lot, AIS having only three base stations in Bangkok was correct couple of years ago not anymore. All of them are installing more every day. DTAC in fact is in the process of modernizing their whole network so most likely will be good on quality wise once completed.
AIS has wide range of WiFi hotspots as well, although i never use them as i don't do youtube or download movies on mobiles hence my 1GB data plan covers my heave email and internet use.
It's all on their web pages easily available to check coverage etc details.
Also there is no need to use pre-paid sims anymore as foreigners can have post paid very easy from DTAC. All you need is credit card to back it up. Much cheaper and hassle free compared to pre-paid.

I'd only care about postpaid on TRUE.
This rather forces my Xperia clad hand. Thanks, Mojo.Originally Posted by Mojo
There's been reports in media that TOT would allow AIS customers into it's 2100 MHz network but i haven't seen anything lately. Maybe the deal did not happen when this True - CAT deal hit the fan.
This would have allowed all phones to work with AIS as 2100 is the global standard and pretty much all handsets supports it.
Latest is that they will finally issue the licences for 2100MHz later this year. Who knows if they are really going to do it this time. It's been "by end of the year" past eight years now. If they do expect around six month to get some coverage in larger towns and 12 to 18 months for full swap.

Just in time for the rest of the world to firmly have switched to LTE and bringing their networks up to some serious 4G compliance. Heck, Cambodia has better 4G coverage than Thailand, at the rate Thailand is going.
What frequency does 4G need? How is 3G upgraded to 4G?
Don't they do Google on your computer?
4G

Sadly, the 4G frequency spectrum is all over the place, and there is no real global standard. While 700MHz is a suggested spectrum, different countries use all kinds of different frequencies, including 2100MHz, 900MHz, 1900Mhz, etc... It really doesn't matter.
The only way to get 4G is to purchase a phone that is compatible with 4G *in your specific country* -- as it's not guaranteed to be working in another country. Most 4G mobile devices will also support the full spectrum of all 3G frequencies, meaning that it will work internationally via 3G, and only in your country on 4G, if at all.
Furthermore, none of the current 4G labeled devices comply with the true speed of the 4G standard (ie LTE) and thus should, at best, be considered as 3.5G.
Hope this helps.
