Avelis eSIM does not provide a Thailand eSIM that includes a phone number or SMS capability. The available plans are data‑only, so travelers cannot make or receive traditional telephone calls or send SMS messages directly through the eSIM. However, mobile data can be used for VoIP services such as WhatsApp, Telegram, or iMessage, allowing voice and text communication over the internet. Travelers should confirm that these applications are accessible in Thailand before purchasing a plan, as some destinations may block or restrict certain VoIP services.
