eSIM Travel Tips for Thailand
Thailand is SA's most popular Asian destination: sort your eSIM at home
Thai Airways and SAA code-share on the OR Tambo to Bangkok Suvarnabhumi route. Thailand is about 10 hours from Johannesburg. Set up your HelloRoam eSIM at home the night before your OR Tambo departure. Enable data when you land at Suvarnabhumi and Grab Thailand works immediately for your Bangkok hotel transfer.
Grab Thailand is essential in Bangkok
Bangkok's traffic is legendary. Grab is the best way to navigate Bangkok alongside the BTS Skytrain. Both need live data. Your HelloRoam eSIM keeps Grab and the BTS app running from the moment you land at Suvarnabhumi. No taxi touts needed.
Phuket beach season: lekker connectivity in resort areas
Phuket's Patong, Kata, and Karon beaches are popular with South Africans for their familiarity (warm sea, beach bars, relaxed atmosphere). Strong 4G throughout the Phuket beach strip. Boat trips to Phi Phi and the James Bond Islands drop signal on open water. Download your tour itinerary before boarding from Ao Chalong.
Chiang Mai: night markets and temple tours
Chiang Mai's old city moat area, Nimman district, and the famous Night Bazaar all have excellent 4G and 5G. Grab and local tuk-tuk apps work well. Remote trek destinations north of Chiang Mai have limited signal. Download offline maps before heading to hill tribe villages.
Thai street food: your eSIM is your food guide
Thailand's street food culture is one of the world's greatest. South Africans who love braai culture tend to be very enthusiastic about Thai barbecue and street food markets. Google Maps food reviews, Instagram location tags, and translation apps for Thai menus all need live data. Your HelloRoam eSIM is your Thai food guide throughout the country.
Mobile networks in Thailand: what South African visitors need to know
HelloRoam connects on AIS, TrueMove H, and dtac in Thailand. dtac is a True Corporation brand since 2023, operating alongside TrueMove H. Both networks have strong national coverage across Bangkok and all major tourist destinations. Your eSIM selects the strongest available signal.

Buy before your Thai Airways or SAA flight from OR Tambo, activate at home, and arrive at Suvarnabhumi already on local Thai data. | Thai tourist SIMs are available at Suvarnabhumi airport counters. A HelloRoam eSIM sorted at home is more convenient after a long-haul flight from OR Tambo. | South African carrier Thailand roaming packages can cost R100 to R200 per day. Two weeks in Bangkok, Phuket, and Chiang Mai on SA roaming adds up significantly. |

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.
