yaySIM does not provide eSIM plans for Rwanda that include a phone number, inbound or outbound calls, or SMS. The available Rwanda eSIM offers are data‑only, with no telephony capability.
Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice calls and messaging. However, the availability of these apps can vary, so it is advisable to confirm that the specific VoIP services you rely on are accessible in Rwanda before purchasing the eSIM.
