Kolet does not provide any Thailand eSIM plans that include a phone number or SMS capability. Travelers using Kolet for Thailand will receive only a data‑only eSIM, which gives high‑speed internet access but no traditional calling or texting services.
Instead, users can rely on internet‑based voice and messaging applications such as WhatsApp, Telegram, or iMessage for communication. However, some destinations may restrict or block certain VoIP services, so it is advisable for travelers to confirm that the applications they intend to use are accessible in Thailand before purchasing a Kolet plan.
