Really great experience

Wauw, what a service. Twice got 3 gb for free, friendly fast customer service via instagram and good prices. Pity no larger bundles than 20 gb, but 12,50 euro for this much data is already great priced. Thanks!

Good service but user not friendly platform

First will mention, great service, i am in fact really satisfied with my duch e-sim.

But sadly , truth be told, there is no option or I couldn't find from where it is , to change the languages of the app.

In that state the platform is just user not user friendly for all non duch speakers as myself.

Understandably the service is providing me with a duch number and so Its assumed duch people would be the main customers , but honestly its not a secret a lot of EU citizens as myself that dont speak the language need a duch number when they are in the Netherlands students , tourists or workers...

Just eng translation as an option in settings will make the service more accessible and friendly

SIMYO IS A SCAM COMPANY.

HORRIBLE. PLEASE NEVER CONSIDER USING SIMYO. they're fully a scammer company and will come back and charge u for invoices even after cancelling the subscription, completely removing the sim and wiping it from your phone, and personally emailing them to terminate the number. nothing works. they'll still come back demanding 50 euros for an invoice you "never paid" even though your bank transfers clearly show you making this very transaction back in MARCH when they asked you for another 50 euros. their customer support is horrible. i tell them they're making a mistake, they AGREE that they did (on multiple occasions) yet still persist with having you pay an invoice YOU HAVE ALREADY PAID. genuinely horrible horrible HORRIBLE company and i pray they meet a fate as honourable as they are when they scam you out of a hundred euros.

This is definitely not the experience we want our customers to have. From this review only we can't see any personal information about your account, but we’d really like to figure out what happened here.

Could you please send an email to webcare@simyo.nl

Extremely expensive, unpredictable charges and poor support

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.

Hi M,

Thank you for taking the time to share your experience. We're truly sorry to hear that your switch to Simyo has not met your expectations and that you’ve encountered issues with unexpected costs, communication, and our customer service.

We fully understand how frustrating it can be to receive high charges, especially in your first months with us. At Simyo, we aim to make data usage as transparent as possible through our app and by sending alerts when you're nearing your data limit. We also provide a datalimit that you can add to your subscription for € 0,50 per month to make sure you don't use more data than you have. You can activate this feature on your Mijn Simyo.

Regarding your attempt to cancel via Belsimpel: when a contract is taken out through a partner, the initial cancellation process must indeed go through them. That said, we understand it can feel like being passed around, and that’s not the experience we want to provide.

You also mentioned feeling that our customer service gave generic responses. That’s disappointing to hear, as we strive to not only be friendly but also provide real, helpful solutions tailored to each situation. We always want to learn and improve the moment we fall short to do that.

If you’re still open to it, we’d love the opportunity to review your situation in more detail and see how we can help and to prevent future situations like these. Please don’t hesitate to contact us at webcare@simyo.nl.

Kind regards,
Simyo Webcare

Canceling within 14 days while keeping your number is impossible

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+.

Warning: check your iPhone’s model 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.

Hi Monika,

Thank you for sharing your experience, even though we're sorry to hear it’s been a very frustrating one. We truly appreciate the detailed feedback.

We completely understand how inconvenient it must be to be left without access to your Dutch number, especially while abroad. You're absolutely right: while your iPhone supports eSIM, certain regional models are currently not compatible with Simyo’s eSIM service due to technical limitations on our side, not Apple’s. This restriction is indeed based on the model number suffix, and we sincerely apologize that this was not clearly communicated to you upfront.

Your point is absolutely valid, we should have informed you about this earlier during your chat with our customer service team, and we’re reviewing this internally to prevent similar issues in the future.

We’re glad to hear our team was responsive and that you're now expecting a physical SIM card. While it's not the ideal solution for someone abroad, we hope it will at least get you connected again soon.

Thanks again for the honest review. We learn from feedback like yours, and we’re truly sorry this was your first impression with us. If there’s anything further we can do to support you in the meantime, please don’t hesitate to reach out.

Kind regards,
Simyo Webcare

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!

Thanks for sharing your feedback. We're really sorry to hear that you've had a negative experience and that you were surprised by the extra charges for data usage outside your bundle.

By default, data usage doesn’t stop automatically when your bundle runs out, but we do offer tools like data limits and usage alerts to help avoid this kind of situation.

Only out for money.

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.

Hi Robin,

Thank you for your feedback. We're really sorry to hear about your experience. We understand how frustrating it must be to see unexpected charges, especially when you were only planning to stay in the Netherlands for a short time.

Our goal is always to provide clear options and safeguards, and it sounds like things didn’t go as expected here. When data outside of the plan is used, costs can add up quickly. That said, we never want our customers to feel surprised or overwhelmed by their bill.

We’d really like to look into your case in more detail to see what happened and whether anything can be done. Since we can’t access your account through this review, could you please reach out to our customer service team directly? We’re here to help and want to do what we can to support you.

Beware

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?"

Hi Spam Only,

Thank you for sharing your feedback. We understand how frustrating unexpected data charges can be, especially when they add up quickly.

At Simyo, we do send notifications to help customers stay informed about their data usage. Currently, we have an automatic data block option once the bundle runs out. You can activate this option (it's called Dataplafond) in Mijn Simyo and it is € 0,50 per month.

We’re sorry to hear that your experience with our support chat was not satisfactory. We aim to respond as quickly and helpfully as possible, and we will take your comments on board to do better.

If you’d like, please contact us with your details, and we’ll be happy to look into your case more closely.
