CoreESIM plans for Thailand are designed as data-centric solutions and, as such, do not incorporate a local Thai telephone number. Your existing mobile number will continue to function for traditional voice and SMS services via your primary SIM. Communication applications that rely on data, such as WhatsApp, Telegram, and Apple iMessage, will operate without issue utilizing the robust data connection provided by your CoreESIM.
