Thai SIM, зарегистрированная на паспорт, essential для banking OTPs, Grab, immigration appointments и 2FA login. Купить SIM легко; правильный plan и store экономят деньги и избегают early expiry.

Где купить
| Канал | Плюсы | Минусы |
|---|---|---|
| Airport counters | Immediate data after landing | Tourist-priced packs |
| Official brand stores | Proper registration, receipts | Queues in malls |

Bring passport — photo page and entry stamp. Registration on the spot.
Tourist SIM vs long-stay plan
Tourist SIMs (often 8–15 to 30 days) suit holidays. Long-stay holders move to monthly prepaid or postpaid to avoid mid-extension data cutoffs.
Nomads on DTV: align plan renewal with 90-day reporting calendar so you don't lose OTP access.
eSIM в 2026
AIS, True, dtac offer eSIM QR at flagship stores — useful if phone supports dual eSIM. Airport eSIM kiosks exist; confirm 5G band support for your device.
Need data before you reach a shop? A travel eSIM is a different product: prepaid data (usually no Thai number) that you install before the flight. See Thailand eSIM before you land. It does not replace passport registration when you need OTPs.
Tip
Screenshot phone number and carrier app login after activation. Needed for bank KYC and condo internet orders.

Частые вопросы
Можно ли home country SIM?
Roaming works briefly but expensive for daily Grab and banking OTP.
One SIM for dual-SIM phone?
Common: home eSIM dormant, Thai physical SIM slot two.
Lost passport — SIM still OK?
Report to carrier with police report; number recovery depends on carrier records tied to old passport.
Need VPN?
Not for carrier reasons; some banking apps geo-check — Thai IP or local SIM helps.
