I will come to Bangkok this month and want to buy a sim for roaming, using in Huawei e583c.

I have surfed AIS website many times, but still find the email contact address. Besides, the web pages just partly english, can't find any APN setting or guideline. So, can anyone help...

1. Which AIS sim card pack is suitable for data roaming in Huawei?

2. What is the charges for a 6 days staying period?

3. I need to set APN myself? APN is " internet" , right? How about login and password?

4. Where can I buy AIS sim?

Many thanks

You can use any One-2-Call SIM.

Most data plans run for one month, but there are some daily plans and weekly plans (speed limited) http://www.ais.co.th/mobileinternet/en/internet-package/#2

You can buy a One-2-Call SIM anywhere/everywhere: AIS has a shop at the airport, or just pop in any 7/11, or mall with hundreds of mobile phone counter shops.

Thanks a lot. By the way, what is the different between GSM and One-2-Call?

GSM Advance is the post-paid brand name for AIS's mobile telephone service.

One-2-Call is the pre-paid brand name for AIS's mobile telephone service.
