BetterRoaming does not offer any eSIM plans for East Asia that include a phone number or SMS capability. All eSIM plans available for this region are data‑only, so travelers will need to rely on VoIP or messaging applications to make calls or send messages.
Popular apps such as WhatsApp, Telegram, and iMessage can typically be used over the data connection for voice and text communication. However, some destinations in East Asia may block or restrict certain VoIP services, so it is advisable to verify that the apps you rely on remain accessible before purchasing a plan.
