Customer Reviews
Super fast eSIM!
Got an eSIM from GigaSim and it was so easy to set up! My 5G Internet-Flat was active in minutes. This is amazing. I will totally get another one for my tablet next month. So glad I found them!
Reliable service, again
This is my third time signing up with GigaSim, this time for an eSIM. I've always found their 'Mobilfunkvertrag ohne Laufzeit' to be very convenient. The service has been consistently good across all my devices, and the activation was just as smooth as my previous prepaid SIM-Karte orders. No surprises, which is what I like.
Good plan, slow support
I switched to the Allnet Flat LTE plan last month. The data speed is good for the price, definitely an upgrade from my old provider. Porting my number was a bit slow though, took about 5 business days after everything was submitted. Customer service was hard to reach initially; waited on hold for a while.
Ordering a Datentarif
I ordered a Datentarif with a Speed-Upgrade last week. The website was easy to navigate to find the right plan. I opted for the eSIM, and the QR code for activation arrived in my email within an hour, which was really convenient. The network speed has been solid so far, no dropouts during my commutes. I had a quick question about the EU-Roaming Flat, and their online chat support responded within 10 minutes, which was decent. The only minor thing was that the confirmation email for my order took about an hour to arrive after I completed the purchase, not a big deal but I was checking my inbox a lot. Overall, a good experience for getting a dedicated data plan.

Anyone know if GigaSim offers eSIMs? I just got a new phone and want to try it out instead of a physical SIM.
Hey, I'm thinking about switching to GigaSim. What's the network coverage like? Is it good in bigger cities or more for rural areas?
