eSIM Plans for Thailand - From $3.28 | 5G on AIS, TRUE, and DTAC & More

Your eSIM connects to AIS, TRUE, and DTAC — that's 3 operators giving you the widest possible coverage across Thailand. Your phone automatically locks onto whichever network has the strongest signal at your location. If 5G is available from any of these operators, your device will use it. Otherwise, you'll get 4G/LTE speeds.

Plans start at $3.28 for 1GB over 7 days. Unlimited data starts at $3.28 for 7 day(s). We have 8 plans total for Thailand, and every price is a one-time prepaid payment — no auto-renewal, no hidden fees, no roaming surcharges. Pay with card, PayPal, Apple Pay, or cryptocurrency (Bitcoin, USDT, ETH) with zero extra charges.

Our most popular plan for Thailand is 4GB for 30 days at $6.33 — it covers most trips with plenty of data for navigation, messaging, social media, and video calls. Traveling for just a few days? The 1GB / 7-day plan at $3.28 keeps costs down. Heavy data user or working remotely? Go unlimited starting at $3.28.

Three steps: (1) Buy your Thailand plan on Bitcall and receive a QR code instantly via email. (2) Scan the QR code in your phone's settings while connected to WiFi — you can do this at home before your trip. (3) When you arrive in Thailand, turn off airplane mode. Your eSIM connects to AIS, TRUE, and DTAC automatically. The data validity period only starts counting from the moment you first connect in Thailand, not from when you buy it.

Yes. The Bitcall eSIM runs alongside your existing SIM using your phone's dual-SIM capability. Your home number stays active for incoming calls, SMS, and two-factor authentication codes. The eSIM handles your mobile data in Thailand through AIS, TRUE, and DTAC. You do not need to remove your physical SIM — both work at the same time.

Yes — Bitcall offers data-with-calls plans for Thailand in 15GB options. These include a local phone number for standard voice calls and SMS within Thailand. If you only need data, our data-only plans work perfectly with WhatsApp calls, FaceTime, Telegram, Zoom, and any other internet-based calling app. Both plan types are available on the Thailand page.

You can buy a top-up or a new plan directly from the Bitcall dashboard — it takes about 30 seconds and works from anywhere with an internet connection (use WiFi if your data is finished). The new data activates immediately. There is no limit on how many times you can top up. If you think you might run low, consider starting with the 4GB / 30-day plan at $6.33 for a comfortable margin.

If you have a 5G-capable phone and you're in an area where AIS, TRUE, and DTAC have deployed 5G, yes — your Bitcall eSIM will connect at 5G speeds automatically. Coverage is strongest in major urban areas across Thailand and expanding rapidly. In areas without 5G, your eSIM falls back to 4G/LTE seamlessly with no action required on your part. All Bitcall plans for Thailand support both 5G and 4G at no price difference.
