Grab vs Metered Taxi: Why You Need Data Immediately
Bangkok's metered taxis are cheap and honest when flagged on the street. But the taxi rank at Suvarnabhumi Arrivals is a different environment — touts approach before you reach the official queue offering "flat rate" journeys to Sukhumvit for 600–800 THB. The same journey via Grab costs 250–350 THB with a fixed upfront price and GPS tracking. You need a working internet connection to book Grab before you exit arrivals. Ovosim activates in the air — you're booking your ride before you collect your luggage.
Bangkok Neighbourhoods: Coverage by Area
Sukhumvit (BTS Asok to On Nut) has the densest 5G coverage in Bangkok — AIS has invested heavily in small-cell infrastructure along the BTS Skytrain corridor. Silom and Sathorn (the business district) have excellent 5G indoors and out. Rattanakosin Island (Wat Pho, Grand Palace, Wat Arun) is older infrastructure but maintains solid 4G. The Chatuchak Weekend Market — one of the world's largest outdoor markets — has strong AIS 4G despite 15,000+ simultaneous users on weekends.
BTS Skytrain and MRT Underground Coverage
Bangkok's elevated BTS Skytrain has full 4G/5G coverage at all stations and on the trains between them — you're above ground, so signal is excellent. The underground MRT (Blue Line and Yellow Line) has patchy coverage; signal drops between stations but returns at platforms. The Airport Rail Link to Suvarnabhumi maintains AIS 4G the entire journey. Download Google Maps offline for Bangkok before landing as a backup for MRT dead zones.
Essential Bangkok Apps That Need Data
Grab Thailand — primary ride-hailing, also food delivery. LINE MAN — food delivery app locals prefer over GrabFood. QueQ — virtual queue app for popular tourist sites like the Grand Palace. Citymapper Bangkok — better than Google Maps for combined BTS/MRT/boat routing. All of these require constant data to function. A single offline moment at the wrong time means a 45-minute wait for a tuk-tuk that should have been a 3-minute Grab booking.
Khao San Road and Backpacker Areas
The Khao San Road area (Banglamphu) sits in the historic Rattanakosin district and has decent 4G but noticeably worse speeds than Sukhumvit due to lower infrastructure investment. The surrounding streets — Rambuttri, Chakrabongse, Phra Athit — are narrow and lined with old shophouses that create signal interference. Expect 4G rather than 5G in this area, which is more than sufficient for navigation and messaging.
Floating Markets: A Coverage Warning
The popular floating markets (Damnoen Saduak, Amphawa) are 60–100km outside Bangkok in Samut Songkhram province. AIS coverage extends to both markets with 4G, but the narrow canal areas between stalls can create brief dead zones. More importantly: these markets involve significant navigation on rural roads where offline Google Maps is genuinely useful. Download the route before leaving your Bangkok hotel.

FAQ: eSIM for Bangkok
What is the best eSIM for Bangkok?

How much does an eSIM for Bangkok cost?
Plans start from €5.99 for 1GB. There are no hidden fees or roaming charges.
Does this eSIM work in Bangkok airports?
Yes, the eSIM activates instantly upon arrival. You will have 5G data immediately.
Which network does this Bangkok eSIM use?
Ovosim connects to AIS (Advanced Info Service), Thailand's highest-rated network by Opensignal. AIS has the strongest coverage in central Bangkok, the Sukhumvit corridor, and Suvarnabhumi Airport.
Can I use Grab Thailand with this eSIM?
Yes — and this is the single most important reason to activate before landing. Grab requires data to book rides. With Ovosim active before you exit arrivals at BKK, you avoid the tout-heavy taxi queue entirely.
Does it work on the BTS Skytrain and MRT?
Yes on BTS (elevated, full 5G). MRT underground stations have 4G at platforms but signal drops in tunnels between stations. The Airport Rail Link to Suvarnabhumi has full AIS 4G coverage.
Is this cheaper than buying a SIM at Suvarnabhumi Airport?
Yes. A 7-day AIS tourist SIM at BKK airport costs 299 THB (around €8) and involves a 30–60 minute queue. Ovosim's 7-day plan starts at €5.99 with instant activation and no queue.
Does it cover Pattaya and Phuket day trips from Bangkok?
Yes. AIS covers the entire Eastern Seaboard including Pattaya, and all of southern Thailand including Phuket and Koh Samui under the same plan.
Will it work at the Grand Palace and Wat Pho?
Yes. The historic Rattanakosin district has AIS 4G coverage. Expect slightly slower speeds than Sukhumvit due to older antenna infrastructure, but maps, photos, and messaging all work fine.
