Customer Reviews
Saved money on a new plan
I was looking for a new Handytarif ohne Laufzeit and stumbled upon Sim24. I managed to get the Anschlusspreis sparen deal, which saved me almost 20 euros right off the bat. It was a good feeling not to pay that activation fee. The process was straightforward, and I picked one of their Vielsurfer Tarife. It felt really worth the purchase because I got a lot of data without being tied into a long contract, and the initial cost was really low. Definitely a smart choice for my budget.
Good value, some hiccups
I decided to try a SIM-Only Tarif from Sim24 because the prices looked competitive. The Allnet Flat was under 10 Euro which is great value. Delivery of the SIM took 5 days to reach me in Munich, which was a bit longer than I hoped. Customer service was helpful when I had a question about setting up the eSIM, though I had to wait on hold for a bit. Overall, I'm satisfied with the plan and the network coverage has been solid so far. Just wish shipping was a bit faster.
Got a good LTE plan
Needed a new LTE Tarif and Sim24 had some decent options. I just picked a basic one. The setup was easy enough. Everything worked as expected when the SIM arrived. No complaints.
Easy switch, great data!
I just switched to Sim24 and got their 5G Mobilfunktarif. The Rufnummernmitnahme went super smoothly, took about 3 days. I'm getting so much data for what I'm paying, it's fantastic! Definitely shopping here again for future upgrades, and telling all my friends about it!

Is Sim24 actually any good? Never heard of them before but the deals look sweet. Kinda worried it's some shady budget provider.
Hey, thinking about switching to Sim24. How long does it usually take to get your old number transferred over? Don't wanna be without my main number for ages.
