How to cancel 1-2-Call with AIS and secure your refund in thailand
What is 1-2-Call and why you might want to cancel
1-2-Call is a supplementary mobile service offered by AIS that bundles calling, SMS, and add-ons such as calling melodies (เพลงรอสาย). The service operates on tiered pricing structures aligned to your usage period. Many Thai consumers activate these packages without realising they renew automatically, resulting in unexpected charges month after month.
Yafee has documented hundreds of cases where users intended to cancel but found themselves still being charged weeks or months later. The root cause: AIS provides no dedicated physical cancellation office, forcing you to navigate phone menus or call centres to formally terminate the service.
Understanding 1-2-Call packages and pricing
The table below breaks down the current 1-2-Call offerings and their cost. Pay attention to renewal terms-each package auto-renews unless you explicitly cancel.
| Package duration |

The combined bundle is where most consumers encounter problems. When your 30-day pass expires, AIS automatically enrolls you in the next billing cycle unless you actively cancel before renewal.
Why most consumers want to cancel 1-2-Call
You may seek cancellation for several reasons. Some switch to competing networks. Others discover the package does not suit their actual usage patterns. Many find themselves trapped in a cycle of recurring charges that continue without transparent notification.
Yafee has helped thousands of Thai users escape these recurring billing traps. The primary complaint: the cancellation process itself remains obscure, and confirmation of successful cancellation is rarely provided in writing.
Your consumer rights under thai law
Before you cancel, you must understand the legal protections that shield you when billing disputes arise.
The consumer protection act and your right to cancel
Thailand's Consumer Protection Act, B.E. 2543 (2000), grants you the explicit right to terminate any subscription-based service. Under this law, AIS must provide clear notice when billing starts, and you retain the absolute right to stop charges at any time.
Critically, if you submit a written cancellation request (registered letter or documented call) and AIS continues charging you, you may lodge a formal complaint with the Office of the Consumer Protection Board (สำนักงานคณะกรรมการคุ้มครองผู้บริโภค, OCPB) at telephone 1166 or via their website.
Yafee emphasises: the burden of proof shifts to AIS once you present evidence of your cancellation request. The company must prove it never received your instruction-not the other way around.
Your right to refunds and compensation
If charges appear on your bill after you have cancelled, you hold a legal right to recover every baht improperly collected. The OCPB can order AIS to refund the full amount plus compensation for administrative inconvenience if the company wrongfully refuses.
Your legal position: under section 32 of the Consumer Protection Act, you may demand restitution and claim damages if AIS continues billing after receiving your cancellation notice. This right exists whether or not the company acknowledges receipt of your request.
Preserve all evidence. Screenshot your AIS app billing history, save SMS confirmations, and retain copies of any call recordings or written confirmation the company provides. These documents form your legal shield if escalation to OCPB becomes necessary.
How to cancel 1-2-Call: three methods explained
AIS offers three cancellation pathways. Each carries different levels of documentation security and processing speed.
Method 1: cancellation via AIS call centre (fastest but riskiest)
Calling AIS directly is quick, but without written confirmation, disputes may arise later. If AIS denies receiving your cancellation request, you face an uphill battle to recover wrongful charges.
-
Contact AIS call centre on 1175.
- Operating hours are typically 08:00-20:00 seven days a week.
- Dial from any phone; it costs one unit of credit or uses your remaining prepaid balance.
-
State your cancellation request clearly.
- Say: "ฉันต้องการยกเลิกบริการ 1-2-Call" (I wish to cancel 1-2-Call).
- If requesting melody cancellation, specify: "ยกเลิกเพลงรอสาย" (cancel calling melody).
-
Provide your phone number and account details.
- Give your mobile number and any account reference the operator requests.
- Confirm the operator has entered your number correctly.
-
Request written confirmation.
- Ask the operator to email or SMS a cancellation confirmation immediately.
- If they refuse, escalate to a supervisor and repeat the request.
-
Record the call details for your records.
- Note the operator's name, call time, and date.
- Many Thai users record calls (permitted under Thai law for personal protection).
Critical risk: Without written confirmation, AIS can later claim they received no such request. Yafee recommends combining this method with a registered letter (see Method 3) for maximum legal certainty.
Method 2: cancellation via AIS IVR (Interactive voice response menu)
The automated phone menu offers immediate processing, but again, no written record is generated. Use this only as a secondary confirmation after securing documented proof via another channel.
-
Access the IVR system through either number below.
- Dial *789, then press 4 followed by 99.
- Alternatively, dial *1175 and navigate the menu: press 3, then 4 for cancellation options.
- English-language menu options are available on both numbers.
-
Follow automated prompts to confirm cancellation.
- The system will request your phone number for verification.
- Confirm which service you wish to cancel (1-2-Call, melody, or both).
- The system will provide an automated confirmation code-note this immediately.
-
Screenshot or save the confirmation code.
- Many IVR systems display a reference number on screen.
- If the system sends an SMS confirmation, preserve it.
Caution: the IVR system is efficient but leaves no human record. If a dispute arises, AIS may claim the system malfunctioned or that your input was not properly registered. Pair this method with Method 3 for legal protection.
Method 3: cancellation via registered letter (slowest but most secure)
This method is time-consuming but creates a legally binding paper trail. Once AIS receives your registered letter, the law places the burden on them to prove cancellation did not occur.
-
Compose a formal cancellation letter in Thai.
- Address it to: "AIS Customer Service, Advanced Info Service Public Company Limited".
- State your full name, phone number, and the exact service you wish to cancel.
- Include the date and your signature.
- Sample text: "ข้าพเจ้ากำหนดให้ยกเลิกบริการ 1-2-Call ตั้งแต่วันนี้เป็นต้นไป" (I hereby request cancellation of 1-2-Call effective today).
-
Mail the letter via registered post (ลงทะเบียน).
- Visit a Thai Post office and request a registered letter service.
- Request a proof-of-delivery receipt (เนื้อหาที่ส่ง)-this is your legal evidence.
- Cost is approximately ฿30-50.
-
Send to the official AIS service centre address.
- Advanced Info Service PLC, 93/2 Chaengwattana Road, Saphan Song, Bangkok 10570.
- Alternatively, check AIS's official website for the current billing dispute address.
-
Keep the delivery receipt as your proof.
- Thai Post will return a receipt showing AIS received your letter and the date.
- This receipt becomes your primary evidence if a dispute reaches OCPB.
-
Monitor your next billing cycle.
- Wait 3-5 business days for processing, then check your bill.
- If charges continue, you now have documented proof of cancellation request.
Why Yafee recommends this method: Thai consumer law explicitly recognises registered post as conclusive proof of notification. Once OCPB receives your delivery receipt, AIS must prove they cancelled incorrectly-they cannot claim ignorance.
What happens after you cancel: the crucial follow-up period
Cancellation does not end your responsibility-vigilance during the next billing cycle determines whether AIS respects your request.
Monitor your bill during the first 30 days post-cancellation
Even after cancellation, auto-renewal glitches occasionally occur. The first month is critical. Yafee advises all users to check their bill daily during the 7 days immediately following cancellation.
- Check your AIS bill via the mobile app. Open the AIS application, navigate to "My Account" or "Billing", and review all charges for the past 7 days.
- Look for any 1-2-Call line items. Even a ฿1 charge indicates the system did not process your cancellation.
- Cross-reference with your SMS notifications. AIS typically sends billing alerts by SMS; compare these with your app records.
- If charges appear, photograph your bill immediately. Screenshot the relevant section showing the unwanted charge, the date, and your phone number for OCPB escalation.
Document everything for refund claims
Should unauthorised charges appear, your evidence file becomes your legal asset. Yafee recommends maintaining a folder (physical or digital) containing:
- Proof of your cancellation request (call recording, registered letter receipt, or SMS from AIS confirming cancellation).
- Screenshots of your bill showing the unwanted charge.
- Any communication from AIS regarding the charge or cancellation.
- Timestamps and dates of all interactions.
Recovering your money: the refund procedure
If AIS continues charging after you cancel, you have a clear legal pathway to recover every baht.
Step 1: contact AIS for refund before escalating
Begin with a direct request to AIS. Document this attempt in writing.
-
Call AIS customer service again (1175) and request a refund.
- Reference your previous cancellation request and provide the date.
- State the exact charge amount and the date it appeared.
- Ask the operator to email you a refund confirmation.
-
If AIS refuses or delays beyond 10 business days, proceed to the OCPB.
- Do not wait passively; Thai consumer law requires businesses to respond within 10 days.
Step 2: file a formal complaint with OCPB
The Office of the Consumer Protection Board is Thailand's primary enforcement body for subscription disputes. Yafee has seen OCPB secure refunds and compensation orders within 30-60 days of complaint filing.
-
Gather all evidence into one file.
- Cancellation proof (letter receipt, call recording, or SMS).
- Screenshots of unauthorised charges.
- Your previous correspondence with AIS.
-
Visit or contact the OCPB office nearest you.
- OCPB hotline: 1166 (toll-free from any network).
- Main office: 43 Phetchaburi Road, Makkasan, Bangkok 10400.
- OCPB accepts complaints via phone, in-person visit, or online form at www.ocpb.go.th.
-
Explain the complaint clearly: you cancelled, AIS continued billing, you want a full refund.
- The OCPB officer will guide you through the next steps.
- If your case is straightforward (written cancellation proof + unauthorised charges), OCPB often orders immediate reimbursement.
-
OCPB will notify AIS and request their response within a set timeframe (typically 10-15 days).
- If AIS cannot justify the charges, OCPB will order a refund plus potential compensation.
Your legal position: under the Consumer Protection Act, once OCPB intervenes, AIS must provide evidence that you authorised the charges or that your cancellation request was invalid. This burden now rests entirely with the company, not with you.
Common mistakes that delay or prevent cancellation
Cancellation troubles are preventable. Thousands of users have successfully terminated 1-2-Call by avoiding these critical errors. Below are the pitfalls Yafee sees repeatedly.
Mistake 1: cancelling via the AIS app without follow-up confirmation
Some users assume clicking "cancel" in the mobile app completes the process. The app may confirm the action on-screen, but this does not create a binding legal record. AIS can later claim the app malfunctioned or that your request did not transmit.
Correct approach: if you use the app, screenshot the confirmation screen, then follow up immediately with a call to 1175 or a registered letter referencing the date and time of your in-app cancellation.
Mistake 2: cancelling just before renewal without allowing processing time
If you cancel on day 29 of a 30-day cycle, the system may not process cancellation before renewal occurs. AIS will charge you for another month and claim the cancellation arrived after billing.
Correct approach: cancel at least 5 business days before your renewal date. Check your bill history in the AIS app to identify your exact renewal date, then set a phone reminder to cancel one week prior.
Mistake 3: relying solely on phone cancellation without written proof
Phone cancellations leave no paper trail. If AIS denies receiving your request, you have no legal recourse unless you recorded the call.
Correct approach: combine phone cancellation (for speed) with a registered letter sent immediately after. The letter serves as your legal insurance policy.
Mistake 4: not monitoring your bill after cancellation
Many users cancel but never check whether the charges stopped. Weeks or months pass before they discover unwanted billing continued. By that point, recovering multiple months of charges becomes complex.
Correct approach: set a mobile phone reminder for day 8 after cancellation to check your bill in the AIS app. Photograph any suspicious charges immediately.
Pricing table: all 1-2-Call packages and auto-renewal costs
This table consolidates every 1-2-Call offering so you can forecast total charges and identify which packages auto-renew.
| Package name |
Cost per cycle |
Auto-renews? |
Annual cost (if not cancelled) |
| 1-day pass |
฿29 |
Yes, daily |
฿10,585 |
| 7-day pass |
฿99 |
Yes, weekly |
฿5,148 |
| 30-day pass |
฿299 |
Yes, monthly |
฿3,588 |
| Calling melody add-on |
฿39-฿99 |
Yes, monthly (often forgotten) |
฿468-฿1,188 |
| Combined bundle (30-day + melody) |
฿399 |
Yes, monthly (most common hidden charge) |
฿4,788 |
Notice that a 30-day combined bundle, if left uncancelled, costs ฿4,788 per year-a significant hidden expense for many Thai users. This table underscores why proactive cancellation saves money immediately.
Avoiding future subscription traps: your checklist
Once you cancel 1-2-Call successfully, protect yourself from similar recurring charges in the future.
- Review your monthly AIS bill in full. Spend 2 minutes checking every line item every billing cycle. Yafee recommends the first Friday of each month as your personal "bill audit day".
- Disable auto-renewal for all services. In the AIS app, navigate to Account Settings > Subscriptions and disable auto-renewal for every supplementary service you do not actively use.
- Set price alerts on your phone. Use your phone's calendar or reminder app to alert you one week before any known subscription renewal date.
- Request paper or email bills from AIS. A physical or email copy creates a backup record if the AIS app malfunctions.
- Save all cancellation confirmations for two years. Thai consumer disputes can take time; keep evidence for the full statute of limitations period.
- Document the name of every customer service representative you interact with. If escalation becomes necessary, OCPB benefits from having specific names and dates of prior contact attempts.
