My pocket wifi is huawei e583c, I have tried imobile 3gx last time when I visited Bangkok. It's ok for data roaming in Bangkok, but it was not be supported in airport.

This time, I want to try dtac, but I don't know will dtac support Huawei e583c. I know dtac is gsm1800

Is there any Pre-paid sim and weekly plan suitable for me? And where can I buy it?

I get the APN settings for AIS:

APN: internet

username: ais

password: ais

Is that right?

But I still don't know which prepaid sim is suitable for travellers, a weekly period. I have surfed AIS website, just partly in English. When I try to send enquiry through email, I can't do that. It need a phone number. Confused... can anyone help?

May I ask about the SIM card activation? Let's say 7 days package, 300MB

1. use smartphone to SEND *500*72#

2. after the sim is activated, insert it into the Huawei mifi

3. set the APN and login/password

Is that right? Thanks a lot

Besides, may I know the different between GSM and 1-2 CALL

In the Volume Base Packages, there are options for customers
