Lumbus does not provide an Uganda eSIM plan that includes a mobile phone number or SMS capability. Travelers who purchase an Lumbus eSIM for Uganda receive only a data‑only plan, which covers high‑speed network access without the possibility of making cellular calls or sending SMS text messages.
Those who normally rely on traditional voice or SMS services can use popular VoIP applications such as WhatsApp, Telegram and iMessage to communicate over the data connection. However, some destinations may restrict or block certain apps, so it is advisable to check that the VoIP services you need are accessible in Uganda before completing a purchase.
