Best time for Singapore travellers to visit Bangkok
November to February is the best time to visit Bangkok from Singapore. The cool dry season brings manageable heat and clear skies. Songkran water festival in mid-April is a culturally rich experience but expect large crowds. Singaporeans visit Bangkok year-round as it is one of the shortest and cheapest flights from Changi.
Suvarnabhumi Airport (BKK) is Bangkok's main international gateway. It has 4G and 5G coverage throughout the terminal, concourses, arrivals hall, and transit hotel. The Airport Rail Link directly connects Suvarnabhumi to central Bangkok.
Don Mueang Airport (DMK) for low-cost carriers also has 4G throughout its terminals.
BTS Skytrain (Sukhumvit and Silom lines) has outdoor 4G and 5G at all elevated stations. MRT Blue and Purple lines have 4G at stations. The BRT and bus network have outdoor coverage on all routes. Grab and Bolt rideshare apps work throughout the city.
Singapore-based travellers should activate their eSIM before departure so data is ready when they arrive.

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
