Yes, Stixrs sells eSIM plans that work in Slovakia and include a phone number and SMS capability. Prices for these plans range from about $21 USD for 20 GB to roughly $78.50 USD for 200 GB, and all are valid for 30 days.
The phone numbers provided use the dialing code +33, which is a French number, not a local Slovak code. All plans allow inbound and outbound voice calls and inbound and outbound SMS. If you need a local Slovak number or specific call/SMS limits, it is advisable to confirm the details directly with Stixrs before purchasing.
