sim.de Reviews 

Third class company run by racists. They openly hate immigrants and absolutely openly disrespect you. Intentionally designs to trap you and take money out of you.

The biggest DIssaster of Company i Germany... they ask you to pay the bill that hasn come in their POOR App, and you have to call custommer service and wait aproxx 30 minuts so they can do nothing at the end and just Hang The Phone OFF... Connection is like in 90s maybe 80s ( 40% of the time spend out of your home you dont hava Internet connection.... Shit company from 1 - 10 i would give MINUS 100000

Shit hole company, racist customer service. I had problem with my SMS service and called customer service and they dont speak any language other than german, they took a whole day to solve and later trasnferred to their shitty technical service, and my god the guy who spoke, his namew was carsten or something, he said if I cant speak german i am not suppose to stay in germany and he will not speak until i speak german, i tried very hard to speak in german using help from others and the movemnet i spoke german he hung up the call, this happenned couple of times with other technicians guys i too. They treated me like garbage, PLEASE DONT BUY THEIR SERVICE. They once charge me 58 euros for using 4mb data for when i was in bosnia (outside EU). Man, this company is a scam, their customer service is shit. I email them several times to cancel my contract they said i can only do by calling customer service and they dont speak english and now I am stuckk. I want to sue them

The net coverage was below expectations, Canceling the contract is a hassle. It took me about half a year.

This is a criminal company and I am seeking legal resources to sue them. They not only charged me for a service that I order and never worked, delayed my cancellation requests and now are reporting to their collector to harass me. Avoid at all cost. And if you have been victim of this, please contact me so we prepare a case against these scammers.

Very disappointing experience with SIM.de. They have been charging extra amounts on my bill, and getting help from customer service was frustrating. Their contact center was unprofessional and could not provide any English support or offer a helpful alternative.
In my experience, this company has not been trustworthy, and I would not recommend SIM.de to others.

I would not even give one star SIM.de one star because of their extremely poor customer service. My monthly package costs only €10.99, but they repeatedly charged me higher amounts for services that I never activated and did not use. This issue has been ongoing for a long time.

On top of that, when there was a problem with the direct debit payment, SIM.de did not properly inform me or help resolve the issue. Instead, the matter was passed to a debt collection agency, and the amount they claimed kept increasing over time.

I tried contacting both SIM.de and the debt collection agency several times, but neither provided clear information or a reasonable explanation. They only continued demanding more money.

This has been a very frustrating experience. I would not recommend SIM.de to anyone, and if I know someone who is using SIM.de, I would advise them to switch to another provider.

Internet data is not working on first day of the month. Unable to contact them and email takes way too long

worse experience! i dont even want to waste time on this but want to warn others before considering this! check reviews! I regret not checking before opting for this.

the service there is terrible. They do not want to help when you call and try to maximise their income. Also, when I called them and spoke in German (they do not speak English), they spoke to me like I was trash, and when I asked them to repeat what was said, they just ended the call...

Tried to cancel contract but they work with a trick. Front page has a button to cancel but that cancellation only invites you to call them.
The actual cancellation needs a signed letter and with another month or two gone the company makes a few more euro's off your account.
Not trutworthy, no service.

The most terrible company, I ever came across. So, basically I purchased iphone 17 pro max on offer. They didn't even sent me rejection mail, but when I asked they said it's temporary rejection, then I sent document and guess what ? No reply? I'm now confused atm whether my phone will come or not! I sent multiple mails no reply, very careless behaviour! No update? Literally they wasted my 2 weeks for no reason.

This is the worst service I have ever experienced. The internet has not been working at all since three months, i have imformed them multiple times. yet I am still being charged for the service. There has been no proper response from the customer support team, and despite spending a significant amount of time trying to resolve the issue, nothing has been fixed.

I am extremely disappointed with the lack of support and professionalism. I would not recommend their services to anyone. Please be careful before choosing this company.

SCAM. Never give them your credit card information, they will charge money for ever, even if you do not use their services.

The handling of eSIM activation is a complete mess. If you ever need to delete your eSIM, transfer it to another device, or re-activate it for any reason, do not expect any real support.

You continue paying your bill, but you are left without a working SIM and no clear way to activate it again. Instead of solving the actual problem, customer service responses mainly focus on upselling additional products that have nothing to do with the issue.

The online portal is the only thing they keep referring you to, even though it does not help at all. The same unhelpful instructions are sent repeatedly. It is very obvious that no one fully reads the conversation history — replies are sent just to say “we replied,” not to resolve anything.

Extremely frustrating experience. I would not recommend this service, especially if you value reliable support.

They are scammers.
All of my invoices are paid, and I Just received a letter from the court about an invoice from August.... Which is already PAID FOR.

Stay away from Them!

Never recommend this mafia. Criminal service

One of the worst comany everrrrrr!!!!
we have a contract with them, the customer serivce was actually awful, My SIM card almost never had proper signal in most places.
When I turned it on for just a few minutes in Switzerland, the next month they sent us a €70 bill.
When I wanted to cancel my contract, which was about to end, customer support told me that instead of paying for a few extra months, they could change my SIM card tariff so the contract would finish earlier and I’d pay less.
A few months later, I realized this is one of the company’s scamming methods. There was absolutely no record of that conversation anywhere. They do this just to steal more money from customers.
And because they never keep any logs of customer calls in their system, once you realize you’ve been scammed — like I did six months later — there’s no one you can file a complaint against.
It’s an outrageously shameless form of theft.

One of the worst telecom services I’ve ever encountered. There’s no transparency, and customer support is utterly useless. They activated roaming services on my SIM and charged me over 70 Euros for using only about 5 MB of data. They’ve conspicuously hidden all the detailed information about this on their website. It’s a shady company, and I’m baffled by how the German government allows it to operate and scam its customers.

They are simply the worst; nothing else to add. Too many things to write. I hate them so much. Please never buy their services.
