Instabridge currently offers only data‑only eSIM plans for Romania, and no plans that provide a local phone number or SMS capability. Travelers looking for a phone number or the ability to send SMS through the eSIM must seek other providers that include telephony services. If contact via a phone number is required, they may consider alternative providers that offer Romania eSIM plans with voice and SMS.
Data‑only eSIM plans can be used with popular VoIP applications such as WhatsApp, Telegram, and iMessage over the internet connection, allowing calls and messaging without a local phone number. However, some destinations may restrict or block certain VoIP services, so it is advisable for travelers to verify the availability of the apps they rely on in Romania before purchasing an eSIM.
