sim24.de Reviews 

I found it very difficult while going through so many procedures to terminate my service contract with them. They have so many unnecessary procedures in place to prevent your goal of terminating their contract. For me, it was pure frustration! Their website did not cooperate! It took nearly an hour to complete this small transation. My advise to you is to stay away from this service provider. It will prevent you from being frustrated in the days to come. Especially if you have to deal with their customer service.

The services is really good

One of my worse experiences ever. I am pleased when on the 11 July. I am finished with this unprofessional company I tolerated it for years. Very little help. In all areas. And not tolerance or help if not in fluent German. No matter how polite you are service and help are not there policy DG 2021 /2026

Would put a 0 if I could. Incredibly bigoted team who break up a call because they didn't know your name existed and they don't trust you're the contract owner despite the ability to confirm every required information.
Sad, considering their rates sound great.

The worst company in Germany!

I never witness a customer service like this in my whole entire life, no good response, no English speaker, no hospitality. There is nothing good in this customer service. My Sim get blocked and none of them can help

Still waiting for a “rufnumermitbringen” solution! It’s been 3 weeks and I do not get any answer, my previous phone number was a prepaid card from Variatel. Not Variatel nor Sim24 gives me a solution 🤮

Please don´t use this shit and the worst internet!. My experience with SIM24 was extremely disappointing. The service feels poorly developed and unreliable in everyday use. I repeatedly ran into issues that made it frustrating and inefficient. Instead of being helpful, it often created more problems than it solved. The overall quality is below what would be considered acceptable for a modern service. Significant improvements are necessary in both performance and reliability before it can be recommended.

Worst company ever, nothing but scammers, they deactivated my esim 3 times, cancelled my portal account, deleted my email from their data base, all randomly, so hard to reach and their customer service is the worst park, paying 15€ while having my Esim deactivated most of the time, and when I complain they remove everything related to me, just terminated my contract FINALLY so I can find better provider, never fall for this trap!

I called customer service because my sim card was blocked even though I transferred the money the customer service consultant said we reported you to debt collection and just hung up worst service I ever got

Very Bad Experience
I purchased one SIM card and I’m waiting 13 days I still did not receive my card

Sim 24 is the biggest scam ... 1 star is also too much . I am using their sim tariff since 1 year and their customer service is HORRIBLE. YOU WILL GET BOOKED BY THEIR RUDE AND HATEFUL COLLEAGUES AMD GET THE UNNECESSARY BILLS IF YOU CALL THEIR FOR HELP . I HAVE PAID since them 15 euros more nd sooo many unmcessary pakage bookings , and bills i finally have to call consumer code to stop this and probbaly need to tak lwayet to get out of their shit service

the best in Germany and all over the world

Very fair and good tarrif options and a very responsive ane helpful customer support. You can even solve your issues during the weekend.

My experience with SIM24 has been extremely disappointing. From the beginning, the service felt unreliable and poorly managed. Important information about the contract and charges was not clearly communicated, which led to unexpected issues later on.

Customer support was also very frustrating to deal with. It was difficult to get clear answers, and resolving problems took far longer than it should have. Instead of feeling like a valued customer, I often felt ignored.

Overall, I cannot recommend SIM24 based on my experience. If you are considering this provider, I strongly suggest reading many customer reviews and being very careful before signing any contract. In my opinion, this is not a company I would trust again.

Just got a sim and so far it’s been awful. The ID process was impossible and rude. The customer service around the delay in my process exceptionally rude, I was shouted at. And now I have 35G of data apparently but no network. I can’t even send a WhatsApp.

Let’s see how much they’ll shout at me on the phone for asking why my data plan doesn’t work. It’s ridiculous.

I recently tried to activate a SIM card with sim24, and it has been the worst experience ever. During the VideoIdent process, the agent (Ginger Brown Hair old Woman) was incredibly rude, unprofessional, and judgmental.
Instead of helping me with a minor naming issue on the contract, she treated me with total disrespect just because I am still learning German. She was extremely impatient and ended up hanging up on me while I was still talking, leaving my entire activation process frozen. Now I can’t even access or change my data, and my process is stuck.
I am deeply disappointed with this discriminatory treatment. If you are an expat or don't speak perfect German yet, stay away from this company. They don't care about their customers and the staff is simply unacceptable.

I was a Customer with them over a year. I went on a vacation and turned my phone into flight modus / wifi. They want to charge me 50€ now even though no service was used at any point. I even had proof that my phone was in flightmodus the whole time. I received some automated answer, and after I said that this had customer service experience and scammy behavior I will look for a new phone plan myself. Their next email was a cancellation of my contract WHICH I NEVER ASKED FOR. Don’t use sim24 if you dont wanna end up paying endless hiddens fees. Bad customer service. I will keep the cancellation and go somewhere else.

On top: You are constantly unable to reach an actual service agent. Their website claims Mo-Friday 8-22. It’s 2pm now and I’m getting a message that I am contacting them outside of service hours.

Expert web set upper and list any areas that were incorrect. Easy, fast and affordable.

Worst service provider in Germany
Do not choose it you won't receive the SIM card to your mail box
