Customer Reviews
Consistent service, easy top-up
I've been with Congstar for several years now, mainly using their Prepaid Allnet Flat M. This latest recharge was as seamless as always. I topped up my Guthaben through the app, which is really user-friendly and quick. I appreciate the reliability of their network; I've rarely had any issues with calls or data, whether I'm in the city or traveling. It's why I keep coming back. The prices have remained competitive over time, and I haven't felt the need to switch providers. It's comforting to know what to expect.
Homespot 100 works well, minor setup hiccup
I decided to try the Homespot 100 for my apartment. The delivery was reasonably quick, took about 4 days to reach Berlin. Setup was mostly easy, but I had a small issue getting the LTE Router to connect initially; the instructions could have been a bit clearer for non-techy folks. Once it was up and running, the internet speed has been consistent and good for streaming and general browsing. It's a decent value for money, especially compared to DSL options in my building. The customer service helped me with the connection hiccup promptly. Overall, I'm satisfied, just wish the initial setup had been a bit more intuitive.
Good deal, easy porting
I switched to Congstar for their Prepaid Allnet Flat M. I used a promo code and got the connection fee waived, which was nice. Porting my old number was pretty straightforward, took 4 days. The data allowance is good for my needs, definitely felt like I got a solid value for my money.
Fast delivery, easy activation
Got a new Prepaid Wie ich will SIM-Karte. It arrived in 2 days. Activation online was super easy. No problems at all. Good network coverage.
Good mobile plan, solid support
I ordered an Allnet Flat mit GB+ plan for my new smartphone earlier this month. The ordering process on the Congstar website was pretty straightforward, I just picked my plan and entered my details. The SIM-Karte arrived within 3 days, which was faster than I expected, and activation was simple enough following the instructions provided in the package. I had a quick question about setting up the eSIM with my Apple iPhone and used their online chat support; the agent was helpful and resolved my issue within about 10 minutes. The network coverage in my area (near Munich) has been consistently good, on par with what I had with my previous provider. Data speeds are as advertised. So far, a smooth experience overall.
Decent service, slight delay
I signed up for the DSL 100 plan and also grabbed a new Samsung Galaxy smartphone. The setup was mostly smooth, the internet speed is as advertised, and the phone arrived in perfect condition. Customer service was helpful when I called about the installation date. My only complaint was that the phone took 6 days to arrive, a bit longer than I expected, but overall a positive experience.
