The summer offer starts on 1 July 2026 and runs until 31 August. Tariff customers can use the Letní data package with 15 GB. The package can be activated twice between 1 July and 31 August 2026, and the second package can be activated immediately after the first set is used up, without waiting until the end of the month. The data is valid in the Czech Republic and across the EU. Once Letní data is used up, the original data from the tariff continues to be used automatically. Customers can activate Letní data in the Můj T-Mobile app in the “Packages” section.
“We bring to our customers a special summer offer that includes 30 GB of data, practical gifts and also a special discount for a good-value purchase of a new mobile phone, TV or notebook. We want them to enjoy summer #MeziSvými and as pleasantly as possible – whether they are at home, on the road or with family and friends,” added Petar Babić, Chief Commercial Officer for B2C at T-Mobile Czech Republic.
Magenta Moments users can pick up two practical gifts at all T-Mobile stores: a magenta water bottle and a Magnum ice cream by Algida in two flavours: Classic and Almond. The gifts are available from 1 July until stocks last. Additional benefits include raffles and competitions for a range of experiences, such as a trip worth CZK 100,000 or a trip for two to Florence.
In addition to the standard acquisition offers for fixed internet (CZK 299/month for the first six months) and TV (CZK 199/month for the first half-year), customers can also newly receive a discount of up to CZK 10,000 on a new device during the summer.
