yaySIM does not offer Liberia eSIM plans that include a phone number or SMS capability. The only plans available from this provider for Liberia are data‑only, so travelers will need to rely on VoIP applications such as WhatsApp, Telegram, or iMessage for voice and messaging. While these apps generally work over a data connection, some destinations may block or restrict specific services, so users should confirm that the apps they depend on are accessible in Liberia before purchasing a plan.
