Frequently Asked Questions

What is the difference between the O2 Internet on Your Mobile Start tariff and the O2 Internet on Your Mobile tariff?

The difference is the amount of data you can transfer, not the data transmission speed. O2 Internet on Your Mobile Start has a monthly limit of 150 MB of transferred data (FUP) and is designed mainly for regular browsing of websites and communication. O2 Internet on Your Mobile has a monthly limit of 500 MB and is suitable for smart phones. It can be used for more demanding data applications like maps, navigation or videos.

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 *11 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.

When is FUP drawing cleared?

On monthly tariffs you have a quarter of your monthly limit of transferred data available every week. That's so you don't accidentally use up your months' allowance in a week. At the start of every week you are given more data transfer allowance. The week is calculated from the date Internet on Your Mobile was activated. If you use Internet on Your Mobile for a Day, your download limit is 30 MB and you have 24 hours to use it.
