MobiMatter does not provide an Uzbekistan eSIM that includes a local phone number or SMS capability. The provider only offers data‑only plans for the destination. Travelers who need calls and messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but these are not guaranteed to work everywhere; some destinations may block or restrict certain VoIP services, so it is important to check that the apps you rely on are accessible in Uzbekistan before buying a plan.
