The number transfer process is very simple. You contact your existing operator to request an OKU code (subscriber verification code). They will give it to you either immediately or by the next working day. At www.telestica.cz, you choose your tariff and fill in the phone number to be ported and the OKU code you have received at the end of your order. Once the order is submitted, we will contact you to verify the information and the desired date of number porting. Before the actual porting of the phone number, you will receive a new SIM card from us to which your number will be ported on the scheduled date. The deactivation of the SIM card of the leaving operator will be carried out on the scheduled day between 0:00 and 2:00. The new SIM card will then be activated on the Telestica network between 4:00 and 6:00. From now on you can use our services. If you are unclear about anything, we will be happy to advise you and guide you through the number transfer on our customer line 730 731 732.

A mobile virtual operator is an operator that does not manage its own infrastructure but uses the infrastructure of another operator. Telestica uses the T-Mobile network, which is characterised by excellent coverage throughout the country and the fastest 4G network.

When you call our information line, you always speak to live operators, not automated machines that often hang up and still can't solve your problem. In addition, the operators are our employees, so they are always qualified to answer any questions you may have.

You can order services on-line at www.telestica.cz , by phone at the customer line 730 731 732 or in person at Bašty 2, Brno.

Call us on 730 731 732 and we will block your SIM card and issue a duplicate.

We are not primarily focused on this type of service, but if you call our customer service line, we will try to support you in this area as well.

All you have to do is recommend our services to someone, such as other family members, acquaintances, colleagues or friends. For everyone who becomes our customer, you will get your flat rate for 3 months for free. This promotion is cumulative, so you don't pay a flat rate for half a year for two referred customers and a full calendar year for four customers. We forgive the flat rate up to the tariff of the customer you bring in.

Yes, unused minutes are carried over to the next billing period.

When you run out of data, your internet will stop and you can increase the amount of data by switching to a higher internet plan.

Calling tariffs can be changed at any time and the change will be reflected in the following billing period. Internet can also be changed or added at any time and the change will be reflected immediately after the request is processed. You can use all the dates of your subscribed Internet plans in a given month.

If you live in a border area, check which network you are calling on. In the EU, you can call at the same price as at home. If you're in a border area between an EU country and a non-EU country, you can manually set your device to the operator of that EU country. If you don't want to use data abroad, you can turn it off on your phone.

Calls to non-subscriber numbers are specially charged. The price of calls for these services is determined by the roaming partner itself and the service provider only recharges the customer the price communicated and charged by the roaming partner.

The services provided abroad correspond to the technical capabilities of the local operator whose services you are using. The same conditions apply to the quality of service as in the Czech Republic.

Complaints are handled as standard, as with other services.
