Turkmenistan SMS Best Practices, Compliance, and Features

Turkmenistan SMS Market Overview

Market Conditions: Turkmenistan's mobile market is characterized by strong government oversight and regulation of telecommunications. The country has limited competition in the mobile sector, with state-owned TM Cell (formerly Altyn Asyr) being the dominant operator. SMS remains an important communication channel, particularly for business messaging, though mobile internet and OTT messaging apps are gaining popularity where available. The market shows a preference for Android devices due to their affordability and availability.

Key SMS Features and Capabilities in Turkmenistan

Turkmenistan supports basic SMS functionality with some restrictions on content and delivery methods, particularly around URL filtering and sender ID requirements.

Two-way SMS Support

Two-way SMS is not supported in Turkmenistan according to current carrier specifications. Businesses should design their SMS strategies around one-way communication flows.

Concatenated Messages (Segmented SMS)

Support: Yes, concatenated messages are supported, though availability may vary based on sender ID type.
Message length rules: Standard SMS length limits apply - 160 characters for GSM-7 encoding, 70 characters for UCS-2 encoding.
Encoding considerations: Both GSM-7 and UCS-2 encodings are supported. Messages using UCS-2 (for non-Latin characters) will have shorter length limits.

MMS Support

MMS messages are not directly supported in Turkmenistan. Instead, MMS content is automatically converted to SMS with an embedded URL link. Note that URLs in SMS content require special registration with carriers to avoid filtering.

Recipient Phone Number Compatibility

Number Portability

Number portability is not available in Turkmenistan. Mobile numbers remain tied to their original carrier, simplifying message routing but limiting consumer choice.

Sending SMS to Landlines

Sending SMS to landline numbers is not possible in Turkmenistan. Attempts to send messages to landline numbers will result in a 400 response error (code 21614) through the API, with no message delivery and no charging.

Compliance and Regulatory Guidelines for SMS in Turkmenistan

SMS communications in Turkmenistan are governed by the Law of Turkmenistan on Electronic Communications (2010) and overseen by the Ministry of Communications. Businesses must comply with strict content filtering regulations and maintain transparency in their messaging practices.

• Standard keywords include: STOP, ????????, HELP, ????????????
• Response to HELP/STOP commands must be immediate and free of charge

• Maintain their own suppression lists
• Honor opt-out requests within 24 hours
• Keep records of opted-out numbers for at least 1 year

Time Zone Sensitivity
