ZenSim does not offer any eSIM plans with a phone number or SMS capability for the Northern Mariana Islands (incl. Saipan). All ZenSim eSIMs sold for this destination are data‑only and do not support inbound or outbound telephony or text messaging.
Travelers who require voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict certain VoIP services, so travelers should verify that the apps they rely on are accessible in the Northern Mariana Islands (incl. Saipan) before purchasing a KenSim data‑only eSIM.
