Ubigi does not provide an eSIM plan for Guyana that includes a phone number or SMS capability. Travelers who need a number for calls or the ability to receive text messages will find only data‑only options from this provider.
For voice and messaging needs, users can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may restrict or block particular apps or services, so it is advisable to confirm that the apps used are accessible in Guyana before purchasing an eSIM.
