I switched to Simyo to save money with a SIM-only plan, but it turned out to be the opposite. In my first month, my bill came out absurdly high because they said I had exceeded my data limit — and charged me over €100 in extra MB, at a price that honestly makes no sense. After I complained, they gave me a “discount,” but it still felt like I was being overcharged for something that should have been better communicated or controlled.
I tried to cancel within the first month, but they told me I had to contact Belsimpel (where I got the contract) instead of helping me directly. It felt like they just passed the problem on.
A few months later, now, October I had no Wi-Fi at home, and suddenly my usage showed 20GB of videocalls in one day — which I find very hard to believe. I accepted I might have used more, but the costs were insanely high again, and not only for that month. Somehow, the next month (November) already showed another €100+ before it even started.
The costs are unpredictable, their pricing is not transparent, and the customer service gives you generic answers instead of real solutions. I deeply regret switching to Simyo. I would not recommend it to anyone who wants a clear and fair phone plan.

Getting a good sim only deal was fine. Unfortunately due to personal reasons I wanted to cancel the subscription within the 14 days that it is allowed. However when I wanted to do so I couldn't keep my number. Since a lot is coupled to my phone number I am staying. But it feels like a bad service to me. Probably if I didn't have this issue I would be more then happy.

I live in Amsterdam, very recently went on a skateboard trip to Geneva Switzerland for a week and all went perfect.
All 5G speeds, maybe 10% of time 4G+.
Super satisfied so far.

I am really satisfied with Simyo.
Simyo uses KPN line so it is so stable and fast as well.
I found Simyo App is also quite easy to use and check my status and usage.
I am so happy I am with Simyo.

The website is good and efficient. I got the sms to confirm the fact that I want to keep my number.

I’m a very new client. I already have one positive and one negative experience and I’m writing this review to warn anyone considering eSIM.
I wanted to transfer my old number from Odido to Simyo and switch to eSIM. Since I’m abroad at the moment I got in touch with Simyo via WhatsApp.
I got a reply pretty fast and I was told everything about the procedure and basically assured that it’s totally possible.
So I started the process. My number was transferred after few days but I was not able to install the eSIM. I contacted Simyo again via WhatsApp providing the screenshot of the errors I’m getting.
And now the fun part…(not funny for me though): even though my iPhone supports eSIM I can not use it because my model number is not matching the approved model numbers! Only model numbers with last characters DN, ND, ZD, or NL are approved.
So if you have a iPhone purchased anywhere else than NL region you are out of luck installing the eSIM.
This is purely Simyo’s decision not iPhone limitation.
And fair enough, if that’s how they want to do their business, so be it.
But I was not informed about it or never suspected that this kind of limitation even can exist. No one in the chat mentioned it.
And guess what? If I knew in advance, I wouldn’t transfer my number.
Now, I have no access to my Dutch number, no eSIM, and no possibility to revert the process.
I was offered physical SIM as an option.
But since I’m abroad it won’t reach me easily, I have to use my friend’s address in NL to forward me the card.
So all of you travelling and living abroad, check your iPhone’s model number before purchasing eSIM.
You might be out of luck!
I’m giving 2 stars in this review because the customer service was easy to reach.
The story will be continued after my SIM (physical SIM!) arrives.

Hii,
First thank you for your services. Everything has been okay so far for me; however, it is terrible that the application is only supported in Dutch language. I don’t understand a word in Dutch so it makes it hard for me to work with the app!

Reply from Simyo
It is a scam company they took 110 euro for 40 mb outside the bundle and I didn’t know that Internet will not stop automatically when I reach my limit

Reply from Simyo
I paid for an e sim because i’m in the netherlands dor just a month. And apparently i went outside my plan. The e-sim was 11 euros which is really good. But the fact that they “block” my sim when i’m already 100 euros over is a bit shit. So i bought some more mb’s for internet and it happend again. NOT 100 EUROS BUT 250 EUROS. So now an 11 euro plan turns into 361 euros. Great.

Beware: there is no way to tell Simyo to disable your data service when your data runs out. Why does this matter? Because they immediately charge you 0,15 EUR / MB. That’s about 40 EUR for a 5 minute YouTube video. Yes, they send notifications, but if like me you don’t monitor your text messages and email by the minute, you may find yourself with a huge bill. It’s an exploitative and unethical business model and I’d be shocked if it’s not illegal. Their support chat can take half a day to get back to you and let you know they’re not going to help you. The design of the app is confusing and looks like a German website from 2005, and seems like it was developed by 2 low-skill programmers. If you’re reading this and you’ve experienced anything similar with Simyo, please chime in with your experience and report them to the ACM (Autoriteit Consument & Markt) if you think it’s justified. These people are getting rich off by extracting cash from people in NL who probably live day to day or paycheck to paycheck.
EDIT: I cannot reply to Simyo's response to my original message, so I'm including this addition. I've been in touch with your support team and have spoken to probably 15 or so different members and have asked specifically about disabling my data once I runs out, rather than charging 0,15 EUR / MB, and A) either none of them were aware of it, which would be another failure of yours, B) they all lied and pretended they did not know about it, or C) you are lying in your response.
Where EXACTLY in Mijn Simyo can I find this feature, if indeed it exists? It's not under Settings/Instelingen in the iOS app, and on the website, the page for Dataplafond on the website (can't include a link due to restrictions on trustpilot) says "MISTAKE: This page does not exist (anymore) Do you want to go somewhere else?"

Relatively good service and affordable prices

Reply from Simyo
I was charged the maximum data rate of 70€ for data I never used abroad (outside EU), at a rate of 5€ per MB. This was despite the device roaming being switched off, being on flight mode, and turned off during the flight.
As soon as I turned my phone back on, I received an SMS from Simyo that I had reached my maximum “out of EU data usage” during the time of my flight, before I even landed!
The customer service wasn’t helpful, and I’ve now filed a case for my legal insurance to handle. I believe Simyo’s eSim service is at fault here, since I didn’t have such problems with a physical sim from them, tele2 etc before.

Reply from Simyo
very unprofessional customer service, I've ordered an iphone via their subscription and paid half of it directly. The order was rejected (while they have already taken the money) and the customer service was not able to give me any reason behind that, nor fixing the problem.

Reply from Simyo
No English translations... No warnings when I made an international call.. even though my phone has roaming turned off. It cost me €27 for a 2 min call.... No way to add roaming bundles. App needs an English version.

It's hard to switch from SIM only to prepaid. Also not transparent what happens to credit on accounts when switching

Reply from Simyo
I ordered a prepaid eSim to download it looks like I need to call customer service to get an activation code, no body answers, and once they answered and told me we are going to call you back but still I'm waiting for their call, terible application as too.
