Which transmitters can I use in the voice offer?
The SIM card, in the voice tariff, enables the use of our main partner's, namely Play's, transmitters. Additionaly, if the quality of Play's coverage is not satisfactory, you can check if there are any transmitters from T-Mobile or Plus available, at your location. In case of connecting with transmitters from Play, the maximum Internet connection speed will be up to 70 mbit/s (download) and 20 mbit/s (upload), and 1,5 mbit/s in national roaming. While in international roaming, you may connect to the Internet with the maximum speed offered by each roaming operator.
