"[SALE] 4G SIM Card (Klook Counter at Siam Center or BKK Airport Pick Up) for Thailand"
13 Sep 2018
This is my second time to buy a data sim in Bangkok via Klook. Although, the instructions were clear, I had a hard time locating their kiosk. Back then they were on the ground floor near the airport exit doors. Now, they are in the B floor (basement) next to the train station. I use the sim with my wireless router. I never had issues before but now everytime I turn on my wifi router, I had to login to my router ip and turn on LTE and data roaming before I could reconnect. Other than that, I am happy with the internet connection. It was fast and I did not experience any slow down after three days of using data. If you frequent Bangkok, it is best to buy your own wifi router and sim than renting wifi router. It is more economical. However, if you are not worried about paying more then do what works for you.
