Customer Reviews
Reliable internet as always
I've been with 1&1 for years now, mostly for their DSL Internet. This time, I upgraded to a Glasfaser Anschluss and it was just as smooth as my previous service changes. Activation took about 7 days, which is what I expected. Speeds are consistently good, no surprises there. My HomeServer connected right up, too. It's why I keep coming back – I know what I'm getting.
Webhosting was fine
I needed Webhosting for a small project and went with 1&1 again. I'd used them before for domain registration a couple of years back. The setup for MyWebsite Homepage-Baukasten was pretty straightforward, got my site live in a few hours. I also added some Cloud-Speicher later on. The only minor thing was the support line had a bit of a wait when I called about an SSL certificate question, but they resolved it eventually. Overall, it's a solid service for what I paid, and I appreciate the consistency.
Good mobile plan
Got an All-Net-Flat with a new Smartphone mit Vertrag. Ordering was easy. Delivery took 4 days. Phone works well, no issues with the network coverage for the 5G Tarife. Satisfied with the purchase.

Share tips, ask questions & help fellow shoppers save more
hey, was looking at some of their mobile plans, how's their network coverage in Berlin? like, compared to Telekom or Vodafone?
thinking about getting a new phone with a contract, does 1&1 offer any trade-in bonus for old phones, or is that just for new customers?
