yaySIM does not offer a Global (World) eSIM plan that includes a phone number or SMS capability. Travelers looking for a Global plan from yaySIM should be aware that the available options are data‑only. If a phone number or call/SMS service is required, they would need to use other providers that support those features.
For connectivity, travelers can still use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages. However, some destinations may block or restrict access to certain VoIP services, so it is advisable to check that the apps required for communication remain accessible in the regions covered by the Global plan before purchasing.
