ByteSIM does not provide an Afghanistan eSIM plan that includes a phone number or SMS capability. The provider only offers data‑only plans for this destination, so travelers will not receive inbound or outbound voice or SMS services from ByteSIM while in Afghanistan.
Users can still use popular VoIP applications such as WhatsApp, Telegram or iMessage over the data connection for calls and messaging. However, some destinations may block or limit access to specific apps or VoIP services, so travelers should verify that the applications they rely on are available in Afghanistan before purchasing a ByteSIM data plan.
