Voyasim does not provide Thailand eSIM plans that include a phone number or SMS capability. Their Thailand offering is limited to data only, so users will not receive a local telephone number for calls or message sending.
Even though Voice over IP apps such as WhatsApp, Telegram, or iMessage can be used over the data connection for voice and text, the availability of these services can vary. Travelers should confirm that the apps they rely on remain accessible in Thailand before purchasing a data‑only eSIM.
