T-Mobile rolls out summer discount in Czech Republic and free 15 GB data offer in Poland

T‑Mobile launched a summer campaign in the Czech Republic running from 1 July to 31 August. Customers who combine mobile and fixed‑line services, especially T Fiber, can receive a discount of up to 10 000 CZK on a phone or other device. The campaign was produced with a hybrid workflow that incorporated generative AI tools for concept, script, art direction and asset creation, while creative decisions remained human‑led.

In Poland, a separate promotion began on 5 August, offering a one‑time free 15 GB data package to prepaid users of T‑Mobile, Heyah and MIX. Activation is done through the My T‑Mobile app, and the data is valid for seven days after activation. The offer is available until 9 August 2026, applies in Poland and roaming zone 1A, and can be claimed only once per SIM.

Both promotions aim to boost uptake of T‑Mobile’s services and highlight its bundled‑service discounts across the two markets.
