Good to Know
- Berlin's broadband is slower than many other German major cities; 40% of connections experience successful speeds, 29% fail, 31% are neutral.
- For nomads staying 1+ months, prepaid SIM/eSIM from O2 (budget) or Vodafone (urban reliability) are cheaper and commitment-free than 24-month contracts.
- If you sign a 24-month mobile or broadband contract, watch for the Neukundenrabatt trap: discounted rates expire after 3-12 months, then jump 20-30 EUR/month higher.
- Mobile coverage in Berlin is excellent (4G/5G in city), but tunnels and some train stretches lose signal briefly; download offline maps before leaving central areas.
- Fiber (FTTH) availability is expanding but still spotty; check your specific address before committing to a broadband plan.
- EU roaming: German mobile data plans work at no extra cost in any EU country (data included).
- Video-Ident verification for SIM activation may fail for non-EU passports; keep Deutsche Post PostIdent as backup.
- German home broadband contracts typically enforce 24-month minimums; short-term nomads should prioritize mobile connectivity over fixed lines.
