Not directly Visa, but related :

"I will enter Thailand again on a Non-O visa to extend after the procedure. Other times I was in Thailand I had an AIS Prepaid SIM with 'unlimited' data, which cost about 1200 Baht.

Now I want to live there permanently and am exploring other possibilities.

So my question is: what operator and formula would you advise is the best to get a decent amount of data (minimum 2 GB/day or 60 GB/month)."

Hello, I will spend the next few years without interruption in Thailand and I have a question regarding Internet. I am planning to buy a sim card with unlimited traffic, it will cost about 900THB per month. I would like to know if it is possible to get a second sim card for the same number so I can use it as a wifi source for my apartment. For example I can use an old phone and activate the Mobile Hotspot. Alternatively there are routers that can be equipped with a sim card. So I would always have wifi at home and also on the road unlimited internet. Can anyone tell me if this is possible?

Edit: When i say unlimited, i mean no speed limitations after a certain amount of monthly usage.

I just realised that while I was actually getting unlimited data for 600B on my AIS package last year, what I bought at the airport for 850B is in fact not unlimited, but rather limited GB after which you are cruising along at 400kb/s

Are there any really unlimited packages left in Thailand on prepaid? Dtac? True? Or is the 25Gb 6Mb/s package as good as it gets these days?

EDIT:

For those interested in coverage, here is a great tool. [[members only])

Seems like DTAC, True Move and AIS cover most of the country, but AIS has significantly better coverage of "4G+"
