TailSim does not provide an eSIM for Bulgaria that includes a phone number or SMS capability. Its offerings for Bulgaria are limited to data‑only plans.
Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to these services, so it is advisable to verify that the apps you rely on are available in Bulgaria before purchasing a TailSim plan.
