gosimless does not offer any Thailand eSIM plans that include a phone number or SMS capability. Travelers can only purchase data‑only plans from this provider. However, popular VoIP applications such as WhatsApp, Telegram, and iMessage can normally be used over the data connection for voice calls and messaging. Keep in mind that some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the applications you rely on are accessible in Thailand before purchasing.
