Unlimited Essential

1GB each day at full speed, then unlimited data at 1.25 Mbps. A balanced option for an Old City stay with regular directions and messaging.

Compare Essential

Unlimited Plus

2GB each day at full speed, then unlimited data at 2 Mbps. Compare for heavier daily use. Plus is not Premium.

Compare Plus

Daily Unlimited options have selectable durations up to 30 days. Premium is not selectable on this Thailand product. Actual service and speed depend on local network, terrain and device.

Arrival and Old City navigation

Before you leave Chiang Mai International Airport, save the address of your accommodation and check its entrance or pickup point. Around the Old City, use mobile data for route checks and ride bookings, but keep a screenshot of your address if your phone loses signal or battery.

Day trips north of the city

Traveling toward Doi Suthep, Chiang Rai or Pai? Choose enough validity for every travel day and download offline maps before leaving urban coverage. Mountain roads and national-park areas can have weak or no service. Do not rely on an eSIM as your only emergency communication.

Buying before departure

  1. Confirm your exact phone model supports eSIM and is carrier-unlocked.
  2. Pick a total fixed-data allowance or daily tier that fits your route.
  3. Install the emailed QR code using stable Wi-Fi and follow its instructions.
  4. On arrival, set AloOui as your mobile data line; follow activation guidance and review roaming on your home SIM to avoid unwanted charges.

Chiang Mai eSIM FAQs

Can I buy a Chiang Mai eSIM without a local SIM card?

Yes. The Thailand eSIM is delivered as a QR code by email. Check that your phone is eSIM-compatible and unlocked before purchase.

Will the Thailand plan also work in Bangkok?

Bangkok and Chiang Mai are both listed destinations on the Thailand product. Choose validity for both stops; connectivity still depends on local coverage.

Is there a Premium tier?

No Premium variant is currently selectable on this Thailand product. Unlimited Plus is a separate daily-allowance tier.

Where can I get installation help?

See the AloOui Help Center. Ask support before deleting an installed eSIM that fails to connect.
