RedSim does not provide eSIM plans that include a phone number or SMS capability for the United States of America. All eSIM offers from this provider in that country are strictly data‑only and do not support inbound or outbound voice or text services.
Travelers who need text or voice functionality can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. These services generally work without a local phone number, but some carriers or regions may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the applications needed are available in the United States of America before purchasing a RedSim plan.
