1.1) Forms and methods of collecting advance payments.

       The company intends to provide prepaid services to users, in accordance with the National Broadcasting and Telecommunications Commission’s (NBTC) announcement regarding the criteria for prepaid billing in telecommunications. This will be in the form of a “fixed package” mobile phone service, where users can pay in advance for mobile phone services and SMS services offered by the company. Users can control their expenses as desired, check their remaining credit balance, and manage their usage period at any time. The criteria and methods for prepaid billing are as follows:

       1.1.1 ) The company’s prepaid billing method is as follows:

       The company’s prepaid billing for short message service (SMS) is as follows:

             (1) Billing based on fixed package

• • Users choose to purchase packages that specify the number of messages and the usage period, such as:
  • The 499 baht package includes 831 messages and is valid for 6 months.

(Average 0.60 baht per message)

• • The 2,499 baht package includes 5,000 messages, valid for 12 months.

(Average 0.50 THB/message)

             (2) Charging service fees in the amount that the service user wishes to pay.

• • Users can purchase packages based on their desired amount of money. The system will calculate the number of messages received according to the rates within the package price range, for example:
  • If a customer purchases a package for 1,000 baht, they will receive 1,666 message credits.

(The system will calculate the credit earned within the 499 baht package price range, using a rate of 0.60 baht per message, because the amount does not exceed the 2,499 baht package.)

• • Credits received from purchases can be used within the validity period of the purchased package, which has a maximum duration of 24 months (e.g., 2 months, 6 months, 24 months, etc.), depending on the package value and terms of service.

             ( 3) Short Message Service (SMS) will have a maximum usage period of 24 months, such as 2 months, 6 months, 24 months, etc., from the date of prepayment or purchase of the package, with a maximum usage period of 24 months (1 month = 30 days). If the number of messages or credits of the service user is exhausted, the service user will not be able to send messages until the prepayment is made or an additional package is purchased.

             ( 4) Users can check the number of remaining messages through the following channels or through the service channels specified by the Company.

A channel that can be checked independently at any time ( 24 hours).

       1.1.2 ) Method of collecting advance payment.

       The company offers two billing models: a “fixed package” and a “prepaid package.” Users pay a prepaid fee according to the rates set for each package. For example, a 499 baht package grants access to 831 messages (including benefits) within a specified period. Alternatively, users can choose a billing model based on their desired payment amount. The system will calculate the number of messages received according to the package price range. For instance, if a customer purchases a 1,000 baht package, they will receive 1,666 messages (the system will calculate the credit within the 499 baht package range at a rate of 0.60 baht per message, as the total amount does not exceed the 2,499 baht package).

Prepaid services are processed on a one-time basis per package purchase, with no accumulation of balance or top-up system. Users must select a new package when the rights to the previous package expire or the usage limit is reached.

The company has established secure and verifiable payment channels, such as:

Transferring money to the company’s bank account.

Payment via electronic invoice (E-Invoice)

Payment through the online system provided by the company.

       The company does not charge any additional fees beyond those specified in the package, and there is no top-up system for accumulating remaining balances. All prepayments are in accordance with the rates and conditions that are transparently announced in advance.

       In the event that a user cancels the service themselves, or is terminated by the company before the contract period expires or before the end of the promotional offer, the user can proceed according to the details of the contract termination procedures and the refund of the unused service fees paid by the user, as outlined in Clause 1.9.

1.2) Details of the terms and conditions if the user is required to use the service within a specified period (if any).

       Prepaid billing does not impose any mandatory payment requirement on users within a specified period.

1.3) Details of options for prepayment and post-service payment, including the channels for sales, except in cases where approval has been obtained from the NBTC to exempt the option for post-service payment or the end of the service cycle, as per Clause 8.

       The company offers both prepaid and postpaid payment options for its services, allowing users to choose the payment method that best suits their needs and convenience.

For this service, the company sets the same monthly service fee for both service types, regardless of the payment method. This means that users who choose to pay in advance will be charged the same rate as those who choose to pay later, without any additional fees or charges due to differences in payment methods.

       However, users who choose the prepaid service will receive additional benefits such as special discounts, usage bonuses, or message bonuses when purchasing packages, subject to the terms and conditions of the company’s promotional offers. Meanwhile, users who choose the postpaid service will receive benefits in the form of convenient payment options and other supplementary services that meet their continuous usage needs. The benefits offered to prepaid users must comply with the provisions of clause 1.6, such as discounts from the regular price, bonus credits, or other benefits that enhance the value of the service.

       – If it is a legal entity, a company registration certificate and a power of attorney (if applicable) are required.

 

1.5) Duration of the advance payment collection period.

       The prepaid billing model allows users to purchase packages according to the terms and conditions set by the company. The maximum usage period of the purchased package is 24 months, such as 2 months, 6 months, 24 months, etc., to comply with the company’s guidelines and regulations.

       The company reserves the right to adjust the minimum package value and service rates according to the company’s policy without prior modification to the billing period. However, users can choose a package that suits their needs through the channels specified by the company.

1.6) Details of benefits or discounts.

       To compare the benefits of prepaid versus postpaid services, the company stipulates that users who choose to pay in advance will receive additional benefits in the form of bonus additional messages or cashback credits.

       The benefits or discounts received by customers will be equivalent to or no lower than the average Minimum Loan Rate (MLR) of the four largest commercial banks: Bangkok Bank, Krung Thai Bank, Kasikornbank, and Siam Commercial Bank, at the time the Bank of Thailand published the information. The company will use this as the primary reference rate to calculate the value of the benefits or discounts, in order to reflect the opportunity cost of customers paying for the services in advance.

• • Example of the Bank of Thailand’s MLR rate as of October 22, 2025
    (Source: Bank of Thailand website www.bot.or.th) :

This information is taken from the average MLR of 4 banks, namely:

– Bangkok Bank’s MLR rate: 6.50%

– Krung Thai Bank’s MLR rate: 6.50%

– Kasikornbank’s MLR rate: 6.72%

– MLR rate of Siam Commercial Bank: 6.50%

The average of the MLR rates from 4 banks.

= (6.50 + 6.50 + 6.72 + 6.50) ÷ 4 = 6.56% per year or 0.546% per month.

• Examples of benefits that users receive when paying for services in advance.

	Prepaid packages	Packages with later payment options.
Package price	499 baht	499 baht
Text credit	831 messages (Average 0.60 baht per message)	800 messages (Average 0.62 baht/message)
Package usage period	6 months	1 month

       Subscribers who choose to pay in advance will receive an additional benefit of 31 text message credits on top of their later-paid package. This is equivalent to a monetary value of 18.60 baht (= 31 x 0.60).

       When compared to the average MLR interest rate of 6.56% per year, or 0.546% per month, the monthly opportunity cost for service users is 2.725 baht (= 499 × 0.546%). When users choose a package with 6 months of prepaid service, the total opportunity cost is 16.35 baht
(= 2.725 x 6).

       It can be seen that service users receive returns in the form of benefits that are of higher value than the average MLR interest rate that the company uses as a reference rate to reflect the opportunity cost mentioned above.

1.7) Service period and payment due date.

Example of a prepaid package :
       A package priced at 499 baht with 831 credits (messages) for 6 months (0.60/message).

The user registered on the date… January 1, 2024	➝	Users select a package and make a payment.
January 1, 2024	➝	The system has instantly added 831 message credits.
January 1, 2024 – June 30, 2024	➝	You can use the messages until your credit runs out or the message expires.
June 23, 2024	➝	Reminder 7 days before package expires. (If there is still credit remaining)
June 30, 2024	➝	Package expired & remaining credits reset. (If no additional purchases are made)
July 1, 2024	➝	Not usable until a new package is purchased.

 

Example of a postpaid package .

– Package 1 costs 499 baht and includes 800 messages per month (at a rate of 0.62 baht per message).

– Billing cycle: 30 days/billing cycle

– Users can start using the service immediately after registration, with payment made later according to the billing cycle.

January 1, 2024	➝	Subscribe to a package.
January 1, 2024	➝	Getting Started (800 message credits)
January 31, 2024	➝	Billing cycle end date
February 1, 2024	➝	Please inform me of the service fees you need to pay.
February 17, 2024	➝	Send a reminder before the payment due date (3 days in advance).
February 20, 2024	➝	Payment due date
March 20, 2024	➝	Temporary suspension of service (with at least 30 days’ notice).
Within 60 days of suspension.	➝	If within 60 days after the temporary suspension of service, the service user has not paid the outstanding service fees, the Company has the right to terminate the service contract. The Company has informed the service user of the exact due date and has given a warning in accordance with the method clearly specified in the contract, as per Section 33 (2) of the NBTC Announcement on Standards of Telecommunication Service Contracts.

Notification before the usage period expires.

The company has a system to notify users before the package expires or the payment due date. The details are as follows:

Notification regarding prepaid packages.

1.8) Details of the procedures in case any other charges are levied as specified in the contract
(if any).

       The company does not charge any other fees as stipulated in the contract.

1.9) Details of the procedures to be followed upon contract termination and the refund of advance service fees paid by the user for unused services, as per Clause 12.

       In the event that a user cancels the service themselves, or is terminated by the company before the contract period expires, or before the end of the promotional package they subscribed to, the company will refund the prepaid service fees for the unused services, calculated proportionally to the number of unused messages. This is in accordance with Clause 12 of the NBTC Announcement on the Criteria for Prepaid Service Collection in Telecommunications Business, B.E. 2566 (2023).

       When customers wish to cancel a service in advance, they can notify the company of their request through the channels specified by the company, such as the website, customer service center, call center, or email address provided by the company. Customers must provide their registered phone number or bank account number, along with supporting documents including a copy of their national ID card and a copy of their bank account statement showing their full name matching the customer’s name, so that the company can properly verify their eligibility for a refund.

       The company will review the refund request within 7 business days from the date of receipt. The company will then consider the remaining prepaid service fee and refund the money to the customer via the specified method, such as bank transfer or check. The refund process will be completed within 30 days from the date of verification of complete documents and information.

       However, refunds of prepaid services will only be processed if certain conditions are met, including cases where the user has unused credits or prepaid funds that have not been used. In cases where the user has only used the service partially, the company will calculate the refund amount based on the remaining proportion.

The company will only consider refunds for services that have not yet been used, subject to the following refund conditions:

• • The user still has any unused credits or messages as of the date the service is canceled or the date the company terminates the contract.
  • Prepaid service fees may not have been used in full or in part. In cases where partial usage has occurred, the company will refund only the remaining amount based on the proportion of unused messages or credits.
  • The company no longer allows users to utilize benefits received from prepaid services, such as bonus messages or special discounts. For example, a 499 baht prepaid package includes 831 messages, of which 31 are considered bonus messages. Users can no longer use these bonus messages.

       If a user’s service is terminated due to a breach of the company’s terms and conditions, such as illegal use of the service or other violations of the agreement, the company reserves the right not to refund any prepaid service fees for services already utilized. However, the company will refund any remaining prepaid service fees proportionally to the unused services, including Value Added Tax (VAT 7%), within the specified timeframe.

       In the event that a subscriber subscribes to a promotional package with a “non-refundable” clause, the company wishes to clarify that if there is any remaining unused prepaid service balance, the company will refund the remaining amount proportionally as stipulated in Clause
12 of the National Broadcasting and Telecommunications Commission’s (NBTC) Announcement on Prepaid Service Collection in Telecommunications.

       The company is committed to adhering to international standards in refunding advance payments to build
confidence among users and ensure fairness to both users and the company. For further inquiries regarding service cancellation and refunds, users can contact the company’s customer service center through the designated channels.

Refund processing time.

How to calculate a refund:

       The company will calculate the refund amount based on the proportion of unused messages from the total number of messages specified in the package, regardless of the usage period.

       The company has a system for storing data on the number of messages used and remaining for users. This data can be used to calculate refunds fairly and transparently.

Calculation formula:

Refund = (Number of remaining messages ÷ Total number of messages in the package) × Prepaid service fee

Refund conditions

– The company deducts only the service fees already used before issuing a refund.

– Refund includes Value Added Tax (VAT 7%)

Example of a refund calculation.

          The 499 baht package includes 831 messages (including 31 bonus messages). If the user has already sent 100 messages, 731 messages will remain.  

          Refund = (731 ÷ 831) × 499 = approximately 439.06 baht

The company will verify the number of messages used in the system and issue a refund through the payment method provided by the customer. This process will be completed within 30 days from the date the company verifies that all information and documents are complete.

Refund methods

The company will issue refunds through the following channels:

– Transfer money to the user’s bank account (registered account).

– Issue a check to the customer (in case the money transfer is not possible).

– Cash refund (for refunds collected at the company’s office)

note :

– The company does not issue refunds via credit/debit cards or e-wallets.

– If the user wishes to change the account for receiving refunds, they must notify in advance and attach proof of identity.

The company may refund prepaid service fees by cash, check, or deposit into the user’s bank account, or by any method specified by the user, in accordance with Clause 34 of the National Telecommunications Commission’s Announcement on Standards for Telecommunications Service Contracts, B.E. 2549 (2006).

1.10) Details of the return of benefits or discounts received by the service user from the service provider, as per item 13.

-If the user has not yet started using the service, whether in whole or in part.

       The company will refund the full amount of the service fee paid and will no longer allow users to use any benefits received from the prepaid service, such as bonus messages or special discounts. For example, a 499 baht prepaid package includes 831 messages, of which 31 are considered bonus messages. Users will no longer be able to use these bonus messages.

– If the user has already used part or all of the service.

       The company will not deduct any benefits previously provided from the refund amount that the service user will receive upon service cancellation. For example:

The 499 baht package includes 831 messages (average 0.60 baht per message).

If a user has already sent 100 messages, 731 messages will remain.

Refund = (731 ÷ 831) × 499 = approximately 439.06 baht

       The company will not deduct or calculate any of the 31 bonus messages back as a discount, as the user is considered to have already received that benefit in full. Any refund will only be based on the remaining credit balance in the system.

       Furthermore, the company will comply with Clause 13 of the NBTC Announcement on Guidelines for Advance Payment of Services in Telecommunications Business, in cases where the service user is not required to return benefits or discounts to the service provider, as follows:

       Users are not required to return any benefits or discounts received from the service provider in the following cases:

• • The user is unable to receive services from the provider due to ongoing issues beyond the user’s control.
  • The service provider has breached a material term of the contract.
  • The service provider has been declared bankrupt.
  • A service provider may alter a contract or service agreement that results in a reduction of the benefits the user is entitled to, except in cases where such alteration is permitted by law.
