How to Call Slovak Republic from the U.S.

Making an international call to the Slovak Republic is easy.

To call the Slovak Republic, you can use either your Ooma Telo-connected home phone or the Ooma Mobile app.

  • First, dial 011 to exit the U.S. telephone system.
  • Now dial the country code for the Slovak Republic, which is 421.
  • Next, dial the 9-digit local number.

Mobile numbers in the Slovak Republic begin with a 9. Keep in mind mobile per-minute rates apply to these phone calls with Ooma.

Calls made through the Ooma Mobile app don’t use any minutes or incur international charges on your wireless bill. Instead, these calls are routed over your data connection and may count against your data allotment if you’re not on an unlimited plan with your carrier. Connect to a Wi-Fi hotspot to minimize data usage.
