Klook DTAC Happy Tourist SIM – Cheapest Thailand SIM Card With 4G Data (3GB) For 8 Days

During my recent trip to Khao Yai and Bangkok, I bought the DTAC Happy Tourist SIM Card from Klook. At only THB 131, it was the cheapest Thailand SIM card I could find online. It provided really good connectivity throughout my holiday, both in the rural areas of Khao Yai and in bustling Bangkok city. This is my full review of the DTAC Happy Tourist SIM card.

DTAC Happy Tourist SIM

DTAC Happy Tourist SIM is a SIM card specially created for Thailand tourists. The network provider is (yup you guessed it) DTAC, which is the third largest mobile provider in Thailand after AIS and True.

4G 8 Day SIM card (3GB)

The SIM card offers 3GB of 4G data for 8 days.

After you finish using the 3GB, you will still have access to unlimited data usage, but at a pitiful speed of 384kbps.

The Happy Tourist SIM also comes preloaded with THB 100 call credits, which is equivalent to around 30 minutes of local talk time.

The SIM card comes with Standard, Micro and Nano size adaptors.

Lowest Price
Currently, the SIM card sells for just THB 131 on Klook, which is the cheapest Thailand SIM card I can find. And interestingly, if you buy from the official DTAC site, it is more than twice as expensive at THB 299.

“Unlimited” Data?
DTAC markets this SIM card as having “unlimited data” after you finish using the initial 3GB, but as mentioned earlier, the unlimited data only has a speed of 384kbps. To get an idea of how fast (or slow) this speed is, we can use this article you are reading as an example.

This simple page has a size of about 1.3MB, which means technically you would need around 3.4 seconds (1300KB divided by 384KB) to load it, which is essentially forever by today’s internet speed standards.

If you are wondering why this is the case, it is due to Thailand’s fair data usage policy. This is basically a way for mobile providers to force you to limit your data usage. Maybe it’s because they want to prevent jamming of the internet bandwidths, or maybe it’s because they just don’t like to see people enjoying fast internet speeds.

In any case, once you hit a certain data limit, your internet speed will be “throttled”, meaning that it will be reduced significantly. For this Happy SIM 4G 8 Day SIM card, the threshold is 3GB.

To be fair, this is just not the case for Thailand. Many countries implement this draconian fair usage policy as well, including Japan and Malaysia.

Staying More Than 8 Days
If you will be staying in Bangkok for more than 8 days, you can purchase a Day Pass by using the THB100 credit that comes with the SIM card package.

You just need to download the DTAC app to purchase it. You can also get it over the counter at any DTAC shop in major shopping malls. (credit to my reader “Lui” who provided this tip).

Purchasing Additional Data
I also saw on the Klook website instructions on how to purchase additional 4G data. For example, you can get an extra 9 GB of data for THB106 by dialling a series of complicated numbers. You can check it out on the Klook website – the instructions are enclosed in a yellow box with the heading “Insider Tips”.

Cancellation Policy
You can get a full refund as long as you cancel your booking at least 24 hours before your collection date. I like this policy because it gives me the flexibility to buy another SIM card if I find a better deal.

4G 15 Day SIM card (8 GB)

There is also another Happy Tourist SIM card which offers 8GB of 4G data for 15 days. You can check it out here. I usually just take short trips of a week or less to Bangkok, so this is not really suitable for me.

Fast and Reliable Connectivity

we enjoyed great connectivity in Khao Yai too!

The wife and I had no problems with the Happy Tourist SIM card throughout our holiday. In rural Khao Yai, our speed got reduced to 3G sometimes. But it was definitely still fast enough for our internet needs, such as checking Google maps, surfing the web, Facebook, Instagram, Whatsapp, etc. In downtown Bangkok, we enjoyed strong 4G data most of the time.

The THB 100 call credits were quite useful too. For example, I called the Let’s Relax spa in Siam Square to make massage appointments (I spoke English).

How To Buy

1. First, I went to the Klook DTAC Happy Tourist SIM website.

2. Next, I selected the BKK Suvarnabhumi Airport pickup option, along with the quantity and date of collection. You can also choose to collect at Siam Center or DMK Don Muang Airport. After my purchase, Klook emailed me the voucher immediately. It was also uploaded into my Klook App under “bookings”.

3. After going out from the Suvarnabhumi Airport Arrival Hall, I took the escalator down two floors to the basement level. Then, I followed the signs and walked in the direction of the Airport Rail Link Station for about 5 minutes. After that, I located the Klook counter at booth RC6. You can check out the map above.

There was no queue when I arrived at around 4pm on a Tuesday. I was lucky because a short queue formed behind me while I was collecting the SIM cards. You can see the picture of the counter above. The counter opens daily from 8am to 11pm.

In total, I took about 10 minutes to get to the booth from the arrival hall. It wasn’t difficult to locate the booth, but it did take some time.

4. At the counter, a rather stoic Klook staff scanned the Klook voucher QR code on my phone, and then activated both SIM cards. She helped me to insert the SIM card into my phone on the spot, and it worked immediately.

How to Unlock SIM Card

If your SIM card is locked to your carrier, you will not be able to use the Happy Tourist SIM card. Personally I have always been able to use foreign SIM cards without any problems because phones in Singapore are not telco-locked. Below are the steps to unlock your SIM:

Step 1. First, check whether your phone is indeed SIM locked. Insert a SIM card from another carrier (borrow from your friends or family) and restart the phone. If there is a signal and you can make outgoing calls, then your SIM is not locked. If not, proceed to step 2.

Step 2. Contact your carrier and ask them to unlock your phone. Repeat step 1 to check that your SIM is indeed unlocked.

Conclusion

On the whole, I was very happy with the Klook DTAC Happy Tourist SIM. I enjoyed great internet connectivity in both Khao Yai and Bangkok. The buying and collection process was fuss free too. Click here to buy the SIM card.
