When using a Samsung Galaxy Ace Plus, GT-S7500, Dtac internet sim, in Bangkok?

And a Samsung Galaxy S2 GT-I9003, AIS, Bangkok?

When having mobile internet turned on, all I see is an "E".

Saw something about 3G on the news today but didn't really understand what it is about.

Thanks.

E = edge

If you had 3G the 'E' would be replaced by '3G'

Settings, About phone, Status

You need to subscribe to a 3G data plan.

Not sure but I think the Samsung Galaxy Ace Plus, GT-S7500 is 900/2100 MHz 3G so a no op on DTAC/TrueMove H, would work on AIS or TOT.

And I think the Samsung Galaxy S2 GT-I9003 is really an SGS1.5, also 900/2100 MHz 3G so AIS or TOT.

Thanks for the replies.

My phone shows under Network mode: GSM/WCDMA

Under Mobile network type it says: EDGE

It says on the box:

HSDPA 7.2 Mbps/Dual Band (900/2100MHz)

Quad band (850/900/1800/1900 MHz)

@lomatopo

Guess I need to change to AIS or TOT to be able to use 3G on my phone, not?

Thanks

Take the phone to your service provider and ask them.
