Billion Connect does not provide a phone number or SMS capability on its eSIM plans for India; only data‑only eSIMs are available from this provider. The plans do not include inbound or outbound voice or SMS services, so travelers cannot use a regular mobile number to send texts or receive calls while in India.
Travelers who need voice or text communication can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to check that the apps you rely on are accessible in India before purchasing an eSIM plan.
