Giga.Tel does not offer a Bhutan eSIM that includes a local phone number or SMS capability. The provider sells only data‑only plans for Bhutan, so travelers who need voice call or text messaging will have to rely on internet‑based applications such as WhatsApp, Telegram or iMessage. Some destinations may block or restrict access to these VoIP services, so users should verify that the apps they rely on are accessible in Bhutan before purchasing a Giga.Tel plan.
