Customer Reviews
Good value, no activation fee
I was looking for a new plan and saw GigaSim had a 0 Euro Anschlusspreis offer for their Datentarife. That saved me 19.99 Euro right away, which was a nice bonus. The monthly rate for the LTE Internet-Flat was also better than what I was paying before. It took a week to port my old number, but the service started right up. Definitely felt like a good deal compared to other options I checked for a SIM-only plan.
Reliable service, fair price
This was my third time with GigaSim. I upgraded to an Allnet Flat 5G this time. Just like before, the process was smooth from ordering to activation. Switched from my old SIM-only plan. I appreciate that the pricing stays competitive, and I haven't had any unexpected charges. It's why I keep coming back, honestly. Consistently good service.
Good data, quick setup
Got the Allnet Flat LTE. Setup was fast, and the data speeds were good for daily use. Took 3 days for the SIM to arrive in Florida. No issues with coverage so far.
