You can use your tariff in the countries of the European Union plus Iceland, Liechtenstein, Norway and Great Britain as if you were in the Czech Republic. It doesn't matter whether you use the Roaming for a Day or World Roaming tariff with Connect from Abroad. Find more information for prepaid card or postpaid tariff.
In addition to checking whether you have roaming, we recommend that you check your Call Limit before you leave (for tariff customers) or that you top up sufficient credit (for prepaid customers). Without the Call Limit or credit you will not be able to make calls from abroad.
