The ETravelSim Philippines eSIM is data-only. There are no incoming calls, no SMS, and no Philippine phone number assigned per the product spec. Use WhatsApp, Viber, FaceTime, or Messenger over the data connection for calls. Viber and Messenger are widely used in the Philippines so most resorts, tour operators, and Grab drivers reach you there. Keep your home SIM active in your phone for calls to your usual number and to receive banking OTPs, with cellular data turned off on that line.
