I have a Mulitple Entry ED Visa (1 year)

Previously I was able to re-enter Thailand the day before the visa expired and be granted an additional 90 days - effectively getting 15 months from the visa.
Am I correct in my understanding that I can no longer do this?

Sure.

I changed from DTAC to AIS as the DTAC 3G connection where I live (Koh Tao) has been terribly inconsistent during the past couple of months.
No option for phone line internet at my house either right now.

My experience changing over:

I did not need to unlock the DTAC dongle - it recongised and accepted the AIS SIM straight away.
Suprisingly, I was also able to use the DTAC 3G software to connect.


The final thing I needed to make sure of was that this area had AIS 2100mhz 3G activated, as opposed to 900mhz which is what AIS previously used (and still does in cetrain parts of Thailand). The DTAC dongle will not accept a 900mhz 3G connection.
I called AIS and confirmed that this area is now using the 2100 band.

Easy

Thanks for the help, got it working now

I currently have a DTAC Aircard dongle (text on dongle: 7.2 Mbps - ZTE MF190A) and would like to use an AIS 12 call Sim card in it.

I have 2 questions:

1. Will the AIS sim card work in the DTAC dongle? Or do I need to buy a new AIS/generic dongle?

2. Do I need special AIS software on my computer to access the AIS 3G network?
My DTAC dongle came loaded with specific DTAC software on it that I use to connect.


Apologies if this has been covered before, I could not find specific answers to both these questions after searching the forums.
