Avoid excessive roaming fees

What is Singtel Thailand roaming?
Singtel roaming lets you use your Singapore SIM while in Thailand by connecting to local partner networks.
You can access mobile data, send texts, and make calls just as you would at home, provided you’ve activated an eligible plan.
Singtel offers both prepaid and postpaid roaming plans, with different durations, data limits, and prices. Without an active plan, all data, calls, and texts are charged at higher pay-per-use rates.
Singtel roaming in Thailand connects to trusted local networks that support 4G/LTE speeds, ensuring reliable coverage across major cities and tourist destinations such as Bangkok, Chiang Mai, and Phuket.
Singtel postpaid roaming plans for Thailand
If you’re on a Singtel postpaid plan, you can activate a roaming add-on before travelling to Thailand.
Most plans can be purchased directly through the My Singtel app, while others are also available via Singtel’s website chatbot or by calling customer service. Plans must be activated in advance, and unused data is not rolled over.

Singtel prepaid roaming plans for Thailand
If you’re using a Singtel prepaid SIM, you can purchase short-term hi!DataRoam packs for Thailand, offering fixed data at set prices.
These roaming add-ons are ideal if you’re looking for low-cost, flexible data while abroad. These data packs can only be purchased and activated using the hi!App. Validity begins from the date of purchase, and you can combine a 1-day or 3-day pack with a 30-day pack, but can’t stack multiple short-term packs at once.

Singtel Thailand pay-per-use charges
If you don’t activate a roaming plan before travelling, Singtel will charge you at standard pay-per-use rates. For Thailand, this includes:
- Data Roaming: $25.00 per MB
- Voice Calls (incoming & local outgoing): $4.10 per minute
- Calls to Singapore or international: $6.30 per minute
- SMS (send): $0.80 per SMS
- Video Calls: $2.00–S$6.50 per minute
At $25.00 per MB, Singtel Thailand roaming pay-per-use can become expensive very quickly. Even routine background syncing or updates from data-heavy apps, such as video streaming, navigation, or social media platforms, can add up to dozens of dollars without warning.
How to use Singtel Thailand roaming
To avoid unexpected roaming charges, activate a Singtel Thailand roaming add-on through the My Singtel app, SMS, or USSD before leaving Singapore.
If you’re unsure how much data you’ll need, using a Data Usage Calculator can help you estimate based on your needs.
For postpaid users, you can activate Singtel roaming via:
