ByteSIM does not provide an eSIM plan for Thailand that includes a phone number or SMS capabilities. All Thai eSIM options from ByteSIM are data‑only; there are no inbound or outbound voice or text services included.
If a traveler needs to communicate while on the move, popular VoIP applications such as WhatsApp, Telegram, or iMessage can be used over the data connection. However, service availability can vary, so it is advisable to confirm that the apps the traveler relies on are accessible in Thailand before purchasing a plan.
