WonderConnect does not provide an eSIM that includes a phone number or SMS capability for Guyana; only data‑only eSIMs are available. Travelers who need voice and messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. These services may be affected by local restrictions, so it is advisable to verify that the apps required are accessible in Guyana before purchasing a WonderConnect plan.
