Cancellation service #1 in Singapore
Ais is commonly used to refer to Thailand’s Advanced Info Service (AIS), a major telecom and internet provider, or to similarly named services and resellers operating in or from Singapore. In Singapore contexts people often mean tourist SIM/eSIM resellers that supply AIS-network access for travellers.
Offerings include short‑term tourist SIMs, eSIM data plans, roaming bundles and related prepaid packages sold by local resellers and eSIM platforms in Singapore.
Some Singapore vendors sell AIS‑network data plans directly; other AIS services (broadband, postpaid) are operated from Thailand and follow AIS Thailand procedures.
Termination timing depends on the product: short‑term tourist SIM/eSIM will typically expire at the end of the purchased period, and access ceases then.
Prepaid data balances and included credits usually expire on service end; unused data is seldom transferable after cancellation.
If hardware (SIM cards, routers) was rented or sold, check the reseller’s return requirements to avoid additional charges.
Some AIS‑related terms state that all fees are non‑refundable and that access ends at the program period with no refunds or credits permitted.
Where seller terms explicitly state “no refunds,” resellers and platform policies may still differ; always check the specific vendor’s purchase terms.
The following table lists Singapore SGD prices published by Singapore resellers and eSIM providers for AIS or AIS‑network access.
| Plan | Price (SGD) | Period | Features |
|---|---|---|---|
| AIS Traveller Tourist SIM (SIMCard.SG) | S$8.50 | 7 Days | Unlimited high‑speed internet (first 15 GB high‑speed; 4G/5G then FUP), 15 Baht call/SMS credit, unlimited use of major social apps |
| AIRSIM Malaysia & Thailand 4G Data | From S$2.00 per day | Per Day (e.g., S$14 for 7 days, S$20 for 10 days) | 4G data in Malaysia & Thailand, optional AIRTALK voice minutes (30 mins free; top‑ups available) |
| Circles.Life Thailand eSIM 3 GB | S$9 | 7 Days | 3 GB data on AIS / TrueMove H network |
| Circles.Life Thailand eSIM 10 GB | S$18 | 15 Days | 10 GB data on AIS / DTAC network |
| M1 Tourist eSIM 150 GB | S$13 | 30 Days | 150 GB for use in Singapore, plus 3 GB roaming data for Malaysia, Indonesia, Hong Kong, Macau & Thailand (data‑only) |
| M1 Tourist Physical SIM 100 GB | S$14 | 30 Days | 100 GB local + 3 GB roaming (Malaysia, Indonesia, Hong Kong, Macau & Thailand), plus voice/SMS included |
Singapore law includes consumer protection provisions that can require remedies where terms are unfair or where a service is misrepresented. A unilateral “no refunds” clause may not always prevail.
Public reports include complaints about unwanted VAS (value‑added services) and daily charges, where users say support canceled subscriptions but refunds were rarely given.
There are also multiple negative reviews for AIS‑branded services on review platforms describing connectivity and billing problems.
One public review source for AIS‑related experiences is Trustpilot; readers should review multiple reports to form a balanced view: Trustpilot - ais.th reviews.
Assuming “no refund” is absolute: many consumers accept “no refunds” without checking statutory rights or the seller’s actual policy for specific products.
Always check the reseller’s refund and cancellation terms before purchase, and verify auto‑renew settings for eSIM or subscription products to avoid surprise renewals.
The table below compares the listed Singapore options by price, period and best use case to help decide quickly which product fits travel duration and data needs.
| Plan | Price (SGD) | Period | Best for |

Useful reseller pages and product pages: SIMCard.SG AIS Traveller SIM, AIRSIM Singapore, Circles.Life Thailand eSIM guide, M1 Tourist plans.
There is no single official AIS Thailand customer service address published for Singapore; many Singapore customers interact through local resellers or eSIM platforms.
Use the reseller contact pages linked above to find local support and contact details for the product you purchased.
For broadband or postpaid services originating from AIS Thailand, you must contact AIS Thailand directly via the channels provided at the time of purchase or on AIS Thailand’s official site; do not assume Singapore reseller channels manage long‑term Thailand postpaid accounts.
Keep records of any cross‑border correspondence and escalate through your payment provider or local consumer protection channels if unresolved.
