yaySIM does not offer an eSIM with a phone number or SMS capability for Mozambique. Travelers can only purchase data‑only plans from this provider, which allow internet access but not traditional voice or text services. For messaging and calls, users can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, although some destinations may restrict access to certain apps. Travelers should verify that these services are available in Mozambique before purchasing.
