I have one from DTAC, costs are some few THB only to keep the Sim 1 year valid. Upload and extension can be done online.

Any SIM other than a Tourist SIM can be kept valid for a year in advance in perpetuity. In fact it is likely the restriction is only for Truemove H tourist SIM. 
Either way, just buy a normal 50 baht SIM and go from there. You can do lots of small top up which will add 30 days of SIM validity at a time until you reach 12 months. Activate the SIM for International Roaming in so you can extend validity whilst abroad by simply tapping in the appropriate code. 

AIS SIM cards are valid for year. 

Not really sure.  The last time I was at Don Muang I tried to get a sim and a cop was hassling me telling me I can't walk up the counter and the true staff couldn't speak a word of English.  I pulled out the money and they ran away like rats.

 

Just say two weeks and give him money.

You can buy additional validity:

Press : *113*90*9# for 90 days extension. Cost 6 Baht

Press : *113*180*9# for 180 days extension. Cost 12 Baht

Not True! 

 

You can easily buy validity up to 365 days for the TrueMove H SIM using the True iService App.

 

Maximum total validity is 365 days: Validity 180 days - 14.02 THB (including tax).

 

These are the conditions as stated in the App:

 

"Customers must activate TrueMove H service for at least 90 days or have accumulative top-up since activation of at least 200 THB"

 

So top up 200 baht and buy validity in the App. 180 days at a time.

 

DTac is the same, but you only need to top-up at least 150 baht before you can buy validity.

I have the same and yes, the longest you can have validity is 90 days, but that resets every time you top up.  So add 50 baht every 85 says or so and your good,  And yes, it can be done easily online - use the True iService app on your phone and it's simple.  I suspect a True shop could change the SIM and keep the same number and give you something valid for 12 months, was going to try but really its no issue to top up so haven't bothered as of yet. 

On the TrueMove app, I can buy additional validity, cheaply.    180 days costs 14 baht.    I can only buy up to 12 months.    I go to Thailand every year so this is OK.    If I didn't go to Thailand, I could set a google calendar reminder to check it every 50 weeks.

I can certainly confirm that the iService app offers the option to extend the validity in 2 ways.  Either "buy validity", THB 8.41 for 90 days for instance, or by topping up credit,  Different amounts give different extension periods (I did mistakenly mention THB 50 for 90 days, actually it only in fact extends mine by 30).  But whatever method is used, the validity can never exceed 90 days.  I tested it a long time ago, bought 180 days for THB 14, result was extended from whatever it was, maybe 10 days, to 90, not 180.  Queried it with True and they confirmed that my SIM (30 day Infinite Thailand) cannot ever have over 90 days validity.

 

It is quite possible that not all tourist SIMS are created equal.

It seems that you were wrong, as confirmed by @Upnotover  

Might have helped if you had told them to convert the SIM to a ‘normal’ SIM in the first instance…

The problem with AIS is that you have to top up multiple times to extend validity to a year. With DTAC and Truemove H normal SIM you can extend validity to up to a year with a single top up and the application of a code via the mobile’s keypad. 
With AIS, it’s perhaps eleven separate top ups. 
If you change the base pack promo on your Truemove H Tourist SIM, you should be able to extend that to a year continuously. 
AFAIK it’s only the Truemove H Tourist SIM that has that restriction.

It is true that you need multiple top ups with AIS however that’s not very difficult to do. I have kept my number for the last 30 years for most of which I was coming to Thailand in two or three trips a year. Now that I’m here permanently, all I do is have a 20 Baht per month top up, set in my banking app, and that keeps the  validity to a year for. Initially you do the number of top ups that allow the maximum time.

How and where do I buy  normal Sim.  And with which carrier
