Customer Reviews
Smooth switch, quick activation
I ordered an Allnet Flat 10 GB plan from winSIM last week. The online ordering process was clear and easy to follow. I opted for Rufnummernmitnahme, and they handled that really well; I just provided the details, and it transitioned without any issues. The physical SIM card arrived in about 3 business days. Activation was quick through their portal. I checked the network speed, and the LTE Highspeed Datenvolumen seems to be consistent with what was advertised. Haven't needed customer support, so can't comment there, but overall, a very positive experience setting everything up.
Easy setup, fair price
Got the SIM-only Tarife. Setup was straightforward. Price was fair. Everything worked right away. No complaints.
Got a Google Pixel, good deal
Needed a new phone, saw they had a Google Pixel with Vertrag that was a pretty sweet deal. Decided to go for it. The phone showed up in good shape, and getting the service activated was easy peasy. Everything just worked, which is always nice. My old number transferred over fine too. No dramas, felt good about the whole thing.
Decent service, delivery slow
I signed up for the Allnet Flat 50 GB plan. The price was attractive, and the contract is monthly cancelable which is a big plus for flexibility. The network coverage has been fine for me in most places. My only complaint was the delivery for the SIM card; it took 5 days to reach Denver, which felt a bit long. Otherwise, the sign-up process was smooth and the service is performing as expected.
Consistent service, always reliable
This was my third time getting a plan from winSIM, this time an iPhone with Vertrag for my daughter. I keep coming back because their deals are consistently good, and the service is reliable. I've always had good network coverage, and their billing is clear. They didn't have any major issues this time either, just like my previous SIM-only orders. It's nice to know what to expect.
Good deal on Allnet Flat
I was looking for a new mobile plan and found winSIM. The Allnet Flat 20 GB looked like the best value for money. They had an offer where the Bereitstellungspreis was 0 Euro, which saved me a bit right away. The monthly fee seemed really competitive compared to other providers I checked. Got my SIM card fairly quickly after ordering. So far, feeling good about the savings.

quick question about those deals winsim always has. if I want to switch my number over from another carrier, do I still get the discount they're advertising, like the 0 euro setup fee? or is that only for new numbers?
hey, was thinking about grabbing one of those unlimited data plans from winsim. anyone know if they actually have an eSIM option? or is it just physical SIMs?
