Why AY YILDIZ for Germany-Turkey?

AY YILDIZ is built around the Turkish diaspora in Germany — the largest single foreign-origin community in the country. Three things make it different from Lebara or Lyca: Turkish-language customer service via phone and chat, Germany-Turkey rate cards optimised below the per-minute rates of mainstream brands, and retail distribution in Turkish neighbourhoods (kiosks, ethnic supermarkets, money-transfer shops). For users with strong cultural and family ties to Turkey, AY YILDIZ is the most natural fit.

Frequently asked questions

Is AY YILDIZ on the same network as O2?

Yes. AY YILDIZ runs on the Telefónica/O2 network with 5G up to 50 Mbit/s. Coverage matches O2-branded plans — strong in cities, weaker outside them than Telekom.

Does AY YILDIZ offer customer service in Turkish?

Yes. Turkish-language customer service is one of the brand's core differentiators. Available by phone and live chat. The website is also fully bilingual (German and Turkish).

How does AY YILDIZ compare to Lebara for Turkey calling?

AY YILDIZ specialises: Turkish customer service + Turkey-tuned rate cards. Lebara generalises: broader destination coverage including Turkey, but no Turkish-language support. If your sole non-EU destination is Turkey, AY YILDIZ wins. If you also call other countries, Lebara is broader.

Can I get an AY YILDIZ eSIM?

Yes. AY YILDIZ eSIM is verified on ayyildiz.de. Order online, complete VideoIdent, scan the QR. Available on both prepaid and contract plans.
