VeloeSIM does not provide eSIM plans with a phone number or SMS capability in Southeast Asia. The plans sold by VeloeSIM for these destinations are data‑only, and do not include any telephony services such as inbound or outbound calls or SMS.
Travelers who need voice or messaging can rely on data‑only connectivity and use VoIP applications such as WhatsApp, Telegram, or iMessage. Some Southeast Asian destinations may block or restrict access to certain VoIP services, so users should confirm that the apps they depend on work in the specific country before purchasing a plan.
