FAQ and technical support

Frequently Asked Questions

Can I use Internet on Your Mobile abroad?

Data transfers on your mobile phone remain active but you are billed roaming charges in addition to the tariff that you use in the Czech Republic. We recommend you check prices and our great data packages before leaving home. You can also contact our 800 02 02 02 line from an O2 mobile number (+ 420 720 720 720) directly when you are abroad. We'll tell you about prices and activate the best data roaming tariff for you.
