MobiMatter does not provide eSIM plans for Ukraine that include a local phone number or SMS capability. Travelers looking for a data‑only connection can purchase a plan from MobiMatter and use VoIP services such as WhatsApp, Telegram, or iMessage for communication. However, some VoIP apps may be blocked or restricted in Ukraine, so it is advisable to confirm that the specific apps you need will work over the data connection before buying a plan.
