Kostenfreie Telefonie in die Ukraine (zeitlich befristet):
Telekom - Free connectivity
Free SIM-cards for refugees (>18 years) on the boarders to PL, HU, SK and RO
Features: flat voice/messaging/data; prepaid SIM cards with deactivated roaming and recharing
DE: Homepage for customers (telekom.de/hilfe/ukraine); as of now, those SIM cards are valid until end of June 2022.
Individual requests: All 540 T-Shops (own and partner shops; not independent dealers) hand out SIMs to refugees with an Ukrainian passport. (Since March 10, 2022; DT media release). The refugee needs to go to the shop himself, so it's not enough that someone else does it for him.
Bulk requests for large humanitarian organizations, which take packages with 100 SIM cards and take care of the personalization process: Online order form; in case of questions contact ukrainehilfe@telekom.de for details (operated by Deutsche Telekom Service); coordinated with the Federal Office for Migration and Refugees in Germany
Free calling/SMS/MMS with DT SIM cards (Magenta + Congstar) or DT fixedline access to Ukraine (country code +380) + free roaming of DT SIM cards in Ukraine. Not free: Ukrainian SIM cards roaming in DT footprint, as users with Ukrainian SIM cards are charged by their Ukrainian operator for roaming, not by DT. (DT media release, March 10, 2022)
