Struggling to know what a DIM is as said in the headline. The only thing which is DIM, is someone who posts a thread without reading what they have typed before submitting.
I have an AIS prepaid SIM for calls topped up monthly with Bht 20. Enough for me.
Then SIM 2 is a DTAC annual SIM @ 6Mb/s, 60 GB per month, plenty for me. Cost me Bht 2300, less than Bht 200 per month. Works perfectly. It can also be used for phone calls if I want to use that old technology.
However, I have just been told by my Internet provider 3BB, that I can get a data SIM INCLUDED in my Bht 749 1000/500 subscription.
Sounds good to me.
