Frequently Asked Questions

Should Bangkok businesses use WhatsApp or Line for customer communication?

Use both. Line for Thai domestic customers, WhatsApp for international tourists, expats and foreign business partners. If you can only use one and your target audience is international, use WhatsApp.

How do Bangkok hospitals use WhatsApp for medical tourism?

They receive inquiry messages, send service brochures with pricing and doctor profiles, coordinate pre-arrival document collection (medical records), arrange airport transfers, provide in-hospital logistics updates and conduct post-treatment follow-up — all via WhatsApp with the international patient.

What are the best broadcast times for WhatsApp in Bangkok?

For international tourist audiences, align with their home time zones. For local expat communities in Bangkok, morning (08:00-10:00) and evening (18:00-21:00) ICT (UTC+7) work well.

According to the WhatsApp Business Platform documentation, businesses that respond to messages within the first hour see significantly higher conversion rates.
