DSL, cable or fibre: finding the right internet plan in Germany (2026)
Connection type, real speed, promo-price traps and router freedom — the complete guide to the right internet plan with no long downtime.
First, clarify the connection type
Before looking at price, only one question matters: what is available at your address? DSL/VDSL uses the phone line and is almost everywhere, cable (via the TV connection) often delivers high speeds, and fibre (FTTH) is the fastest and most stable — but not yet rolled out everywhere.
Always enter your exact address with house number in the comparison. Availability is street-precise: in the same town one building may have fibre and the next only VDSL.
Mobile internet over LTE/5G (a router with a SIM) is a fallback when no good fixed line is available — usually with a data cap and a higher price per gigabyte.
Choose speed realistically
More Mbit/s is not automatically better — you pay for performance you may never use. A single person browsing, emailing and HD streaming is fine with around 50 Mbit/s. A family with several streams, home office and cloud backups is well served by 100–250 Mbit/s.
Mind the words “up to”. The advertised speed is a maximum, not a promise. Providers must state the actually delivered bandwidth — if it falls well short consistently, you have a right to reduce payment or terminate.
Think about upload, not just download. If you are often in video calls, upload large files or game online, high upload helps — usually far better on fibre than on DSL.
Read the price properly: promo vs. follow-on price
The low price in the comparison almost always applies only to the first months. What matters is the follow-on price from month 13 or 25 — calculate the total cost over the whole term, not just the promo period.
Check one-off costs: a connection or setup fee and sometimes shipping for the router. Some providers waive these in promotions — that saves noticeably.
Since the telecoms reform, contracts may no longer auto-renew for a full year after the minimum term: afterwards they are cancellable monthly with one month’s notice. That gives you room to compare again regularly.
Use your router freedom
In Germany you have router freedom: you may use your own router and are not forced to rent the provider’s device. A monthly router rental adds up over the years — a one-off purchase is often cheaper.
If you take the provider’s device, check whether it is rented or free and whether it fits your needs (Wi-Fi range, telephony, smart home).
For large flats, consider mesh Wi-Fi instead of a single router — it often fixes dead spots better than a more expensive plan.
Switching and moving without long downtime
When switching providers the transition is protected by law: your internet may not be down for more than one day between two providers. The new provider usually coordinates the switch.
If you move and your provider cannot deliver at the new address or only on worse terms, you have a special right to terminate — even mid-term.
Plan the switch a few weeks ahead, especially for new fibre connections, as civil works are sometimes required.
Practical tips
- Always enter the exact address with house number — availability is street-precise.
- Calculate total cost over the full term, including follow-on price and one-off fees.
- Choose speed by real need — 50 Mbit/s is enough for most single users.
- Use router freedom: your own router instead of monthly rental saves long-term.
- If fibre is available at a similar price: prefer it — more stability and better upload.
Common mistakes to avoid
- Looking only at the promo price and ignoring the follow-on price from month 13.
- Booking a far too high speed that is never used in everyday life.
- Entering the address imprecisely and booking a plan not available there.
- Paying router rental for years when your own router is allowed and cheaper.
- Missing the special termination right when moving and paying twice.
Checklist before you compare
- Availability checked for the exact address (DSL/cable/fibre).
- Required speed determined by household and usage.
- Follow-on price and one-off costs included in the total.
- Term and notice period checked (monthly after minimum term).
- Decided: own router or provider device.
- For switch/move, appointment planned with lead time.
Frequently asked questions
Which is better: DSL, cable or fibre?
Fibre is the most stable and fastest, especially for upload. Where it is unavailable, cable or VDSL are good alternatives. What matters is what is available at your address.
How much speed do I really need?
Single users are fine with around 50 Mbit/s. Families with several streams and home office are well served by 100–250 Mbit/s.
Do I have to rent the provider’s router?
No. Thanks to router freedom you may use your own router. A one-off purchase is often cheaper than years of rental.
How long is my internet down when switching?
At most one day. Provider switching is legally protected so the internet may not be down longer.
What if the speed is not as promised?
If the actual performance is consistently well below the contract, you have a right to reduce payment or to special termination.
