yaySIM does not offer any eSIM plans for Russia that include a phone number or SMS capability. All available Russia eSIMs from this provider are data‑only, meaning you can connect to the internet but cannot receive or send traditional voice calls or SMS messages.
Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages. However, availability of these services can vary, and some destinations may block or restrict certain VoIP apps, so it is advisable to verify that the apps you rely on are accessible in Russia before purchasing a plan.
