Billion Connect does not offer a Jersey eSIM that includes a phone number or SMS capability. Travelers can only purchase a data‑only eSIM from this provider. If call or text functionality is required, users typically rely on VoIP services such as WhatsApp, Telegram, or iMessage over the data connection. Some destinations may block or restrict access to certain VoIP apps, so it is advisable to confirm that the services you need will work in Jersey before purchasing a plan.
