We are currently planning to return to Thailand in November for a stay of around 90 days.  In the past, we have gone to Big C and purchased prepaid sim cards from the DTAC outlet and it has generally gone well.

Doing a little light surfing it looks like things have changed a bit since we were last there (early 2024), with packages quite a bit more costly.

Between us, we will need a sim each for our phones, plus a data only sim for internet at the apartment.  We have a router etc there already.  What would your best steers be for the current times?  Both our phones can accommodate e-sims apparently, so that may be an option.  In the past we have stayed with DTAC because we found their coverage fairly stable.

Thoughts anyone?

Personally I would go AIS, but if you are happy with DTAC..

Best to diversify anyway. If you have a problem on one network, you have the other network as a back up.

 

Cheapest solution overall are 90 day Marathon/Kongkrapan SIM. 590 to 650 baht.

 

You can order online as eSIM:

Thanks for that.  I'll look into it all.

 

Catholics won't but these in case they are the original sim.

If there is a Thai person in your family, then https://gomo.th/ by AIS.

Thank you . 

 

We have no Thai family members, and we are not interested in anything with a contracted commitment beyond our 90 day stay.  Thanks all the same. 

 

Hopefully your post will be of interest to someone else..

@Maud There is no contracted committment to GoMo. From whence did you surmise that? It is PAYG.

It's currently the best Unlimited deal available. Though, as aforementioned, needs a Thai national to register the SIM.

To be fair, there is https://finnmobile.io/en who offer Unlimited up to 20Mbps data at the same price, on the DTAC network. So if you have a preference for DTAC, it's one to consider.

 

They have a Facebook Community if you'd like to ask questions. https://www.facebook.com/groups/2179834265506084/posts/3137822139707287

Thank you .  It looks like I misinterpreted their pricing on the website.

We don't have a Thai national family member, so will bear that in mind.

It may well be that we elect to have a short term Tourist eSim for the first few days then decide in-country when we've checked our hardware there still works etc.
