I pay 5.99€/month for unlimited voice and SMS, plus 200gb/month. 4G only, no 5G, but who cares.
For a little bit more (9.99€ without shopping for offers) you get unlimited* data on 5G too.
But in my mind that way too expensive.
- = only on 5G coverage, some limits apply on 4G, and its actually like 750Gb/month before they cap you anyway.
Kena Mobile, a low cost operator of TIM. Its a “welcome back” offer after I had switched to a different operator, they offered back this which was cheaper and better coverage in my area.
