GigSky does not offer eSIM plans for the United States of America that include a phone number or SMS capability. Travelers who purchase a GigSky eSIM will receive only a data‑only plan. If a conversation or message service is needed, popular VoIP applications such as WhatsApp, Telegram, or iMessage can generally be used over the data connection for calls and texts. However, it is advisable to verify that these apps are accessible and not blocked in the United States of America before purchasing, as some destinations may restrict certain VoIP services.
