Afghanistan SMS Best Practices, Compliance, and Features

Afghanistan SMS Market Overview

Locale name:Afghanistan
ISO code:AF
RegionAsia
Mobile country code (MCC)412
Dialing Code+93

Market Conditions: Afghanistan's mobile market is served by four major operators: Roshan, MTN (Areeba), Etisalat, and Afghan Wireless Communication Company (AWCC). SMS remains a critical communication channel, particularly for business messaging and notifications, despite growing OTT messaging app usage. The market predominantly uses Android devices, with iOS having limited penetration. A2P (Application-to-Person) messaging is widely used for business communications, with strict regulations around sender ID registration and message content.

Key SMS Features and Capabilities in Afghanistan

Afghanistan supports basic SMS functionality with some limitations, primarily focusing on one-way messaging with mandatory sender ID registration requirements.

Two-way SMS Support

Two-way SMS is not supported in Afghanistan through standard A2P channels. Businesses looking to implement two-way communication should consider alternative communication methods.

Concatenated Messages (Segmented SMS)

Support: Yes, concatenated messaging is fully supported across all major carriers.
Message length rules: Standard SMS length limits apply - 160 characters for GSM-7 encoding, 70 characters for UCS-2 encoding before splitting occurs.
Encoding considerations: Both GSM-7 and UCS-2 encodings are supported. UCS-2 is recommended for messages containing non-Latin characters or special symbols.

MMS Support

MMS messages are not directly supported in Afghanistan. When MMS content is sent, it is automatically converted to SMS with an embedded URL link where recipients can view the multimedia content. This ensures message delivery while maintaining compatibility with local network capabilities.

Recipient Phone Number Compatibility

Number Portability

Number portability services are limited in Afghanistan. Mobile numbers generally remain tied to their original network operator, which helps ensure more reliable message routing and delivery.

Sending SMS to Landlines

SMS to landline numbers is not supported in Afghanistan. Attempts to send messages to landline numbers will result in a failed delivery and a 400 response error (code 21614). The message will not appear in logs, and no charges will be incurred.

Compliance and Regulatory Guidelines for SMS in Afghanistan

Afghanistan's telecommunications sector is regulated by the Afghanistan Telecom Regulatory Authority (ATRA). While specific SMS marketing laws are still evolving, businesses must adhere to general telecommunications regulations and international best practices for messaging.

Explicit Consent Requirements:

  • Written or electronic consent must be obtained before sending any marketing messages
  • Maintain detailed records of how and when consent was obtained
  • Clearly communicate the type and frequency of messages recipients will receive
  • Provide transparent information about the sending organization

Best Practices for Consent Collection:

  • Use double opt-in processes for marketing lists
  • Document consent timestamps and methods
  • Store consent records securely
  • Regularly update and verify consent status

HELP/STOP and Other Commands

  • All SMS campaigns must support standard opt-out keywords:
    • STOP, CANCEL, UNSUBSCRIBE (English)
    • توقف, لغو (Dari)
    • ودرول (Pashto)
  • HELP/INFO commands must provide information in both English and local languages
  • Responses to these commands should be free of charge for users

Do Not Call / Do Not Disturb Registries

Afghanistan currently does not maintain an official Do Not Call or Do Not Disturb registry. However, businesses should:

  • Maintain their own suppression lists
  • Honor opt-out requests within 24 hours
  • Implement internal do-not-contact databases
  • Regularly clean contact lists to remove unengaged users

Time Zone Sensitivity

Afghanistan follows UTC+4:30 time zone. While there are no strict regulatory time restrictions, recommended sending hours are:

  • Weekdays: 8:00 AM to 8:00 PM AFT
  • Weekends: 10:00 AM to 6:00 PM AFT
