BetterRoaming does not offer eSIM plans that include a local phone number or SMS service for Guatemala. Travelers can only purchase data‑only eSIMs from the provider. A phone number and SMS capability are not supported, so callers and text senders must rely on VoIP applications such as WhatsApp, Telegram, or iMessage, which generally work over the data connection. However, in some destinations these apps can be blocked or restricted, so travelers should confirm that the services they need are accessible in Guatemala before buying a plan.
