Frequently Asked Questions

Use an SMS API provider like Twilio, Sinch, MessageBird, or Plivo. Ensure the recipient's number includes the +975 country code and adhere to Bhutan's SMS guidelines and regulations. These APIs offer robust solutions for sending messages while managing delivery and compliance.
Both GSM-7 and UCS-2 encoding are supported in Bhutan. While GSM-7 is common for basic text, UCS-2 is crucial for sending messages in Dzongkha, the local language. This ensures proper character display.
Bhutan's current telecommunications infrastructure, primarily managed by B-Mobile, does not support two-way SMS. This means businesses can send messages but cannot receive replies via standard SMS channels.
While no strict rules exist, best practices suggest sending between 9:00 AM and 8:00 PM Bhutan Time (BTT), which is UTC+6. Avoid sending during religious holidays and festivals out of respect for local customs.
No, sending SMS to landlines in Bhutan is not supported. Attempts to do so will result in a failed delivery with a 400 response error (code 21614), but no charges will be incurred.
Explicit consent is required before sending marketing SMS in Bhutan. This can be written or electronic, and the purpose of communication must be clearly stated during the opt-in process. Records of consent should be maintained.
All SMS campaigns must support HELP and STOP commands in English and Dzongkha. Process opt-out requests promptly (within 24 hours) and maintain accurate opt-out records to ensure compliance.
The Bhutan InfoComm and Media Authority (BICMA) regulates SMS communications under the Information, Communications and Media Act of 2018. They provide guidelines for compliance and content restrictions.
Gambling, adult content, unauthorized financial services, and political campaign messages without authorization are restricted. Religious content requires specific permissions from relevant authorities.
Alphanumeric sender IDs are supported and preserved in Bhutan. Pre-registration is not required, allowing businesses to use their brand name as the sender ID.
The Twilio API provides a simple method. Use the `client.messages.create` function with parameters for the recipient's number (including +975), the message body, and your sender ID.
Short codes are not currently supported in Bhutan for SMS communication. Use long codes or alphanumeric sender IDs for your messaging needs.
Respect local customs, obtain explicit consent, use clear opt-out instructions, send messages during appropriate hours, and localize content by supporting both English and Dzongkha languages.
