On a vacation there was an error switching out my sim card which resulted me using 12Mb in japan, that costs 60 euros. Normally when dealing with phone / sim only subscription companies they just tell you to deal with it. Simyo resolved the issue very fast via whatsapp chat and their excellent customer agents! And the subscription is cheap anyway, i pay about 10 euros a month for 20 gb with kpn. I really recommend simyo!

Data Roaming Charges even after…
Data Roaming Charges even after following Simyo instructions.
I was charged for data roaming, even though my data roaming was off in my settings. When I got the charge, I reached out to customer service, and they told me there was nothing they could do and I should have turned data roaming off in the Simyo app. When I checked their website for how to prevent data roaming charges, they specifically indicate that we need to turn off data roaming in the settings, and they do not mention the app at all.
simyo. nl/en/blog/ data-roaming-aan-of-uit
When I reach out to customer service again about this, they do not clarify anything. They do not escalate. There is no one else to speak to about this, and they can only apologise. Now the charge is €30 instead of €7. I have been with the company for 3 years.

Hello Jessie,
Thank you for your review. We are sorry to see that you had a bad experience with us and that you made extra costs.
To avoid extra costs we always send two warning text messages. Did you saw these messages? If no action is taken after these messages and internet usage is registered on the simcard because the option was on in Mijn Simyo you will pay €0,15 per MB. If you put on our datacap you can not make extra costs in the EU when the internetbundle is fully used. You can read more about our datacap on our website: https://www.simyo.nl/klantenservice/bundels/dataplafond
Can you send us an e-mail to webcare@simyo.nl with your personal information and a reference from this review? Then we will have a look at the situation.

Super bad customer service and weird stuff
First of all somehow Bunq bank is not wanted the thing is that I tried to order an E-sim but that was denied because of Bunq bank. The other this is that the customer service people are really unpolite and you get a feeling that why are you calling here. If you want yourself to be treated like shit I guess you should choose Simyo. Br. Saara

Hi Saara,
Thank you for your review. We’re sorry to hear about your experience. We understand how frustrating it must have been that you were unable to order an eSIM and that you did not feel treated with the level of service you expected from us.
That is certainly not the experience we want our customers to have. We’d like to look into what happened and see if we can help resolve this for you.
Could you please send us an email at webcare@simyo.nl, referring to this review and including your personal details? This will allow us to look into your situation and get back to you.

Unable to solve their technical problems. Only ask for unnecessary payments. Still awaiting for service despite multiple unnecessary payments. Asked for a refund and they refuse.

I do not need you do anything for me. I am asking that you simply provide service as you are contractually obligated.

Thank you for your review. We’re sorry to hear that you experienced the out-of-bundle and roaming costs as so high. We do work with warning messages: you’ll receive a notification when you’ve used 80% of your bundle, and another one when your bundle has been fully used.
If you’d like, we’d be happy to take a closer look at what happened. Please send an email to webcare@simyo.nl, mentioning this review and your personal details. We’ll be happy to look into it with you.

Horrible service: €10 lost, customer service lies about refunds, and system contradicts itself!
I am extremely dissatisfied with Simyo. I tried to order an eSIM, but my orders keep getting rejected due to a "risk analysis", while money is still being deducted from my account. In total, I have lost €10 on rejected orders, and I have not received any refund. I don't even have a Simyo number!
Here is the absurd timeline of my experience:
1. First order (Sept 11): Requested a refund and successfully received it on Sept 16. (The only thing that went right).
2. Second order (Sept 17): Rejected due to an address issue. €5 deducted, never refunded.
3. Third order (Sept 26): Rejected due to a risk analysis. Another €5 deducted, never refunded.
The online customer service (WhatsApp) is a disaster. They first told me a refund was issued on Sept 18. When I proved nothing arrived, they promised me €10 would be refunded within 5 working days. Then, I received an automated email from their system stating the amount would be refunded within 3 WEEKS! They keep contradicting themselves.
I have sent countless screenshots, bank statements (N26), and proof, but they refuse to manually check or escalate to a supervisor. I am being sent from pillar to post.
Simyo, this is unacceptable. I demand an immediate refund of my €10. If this is not resolved within 24 hours, I will file an official complaint with the ACM (Netherlands Authority for Consumers and Markets).

Hi Anna,
Thank you for your review. We are genuinely sorry to hear about the frustrating experience you have had with your orders and our customer service. It is completely understandable that you are upset about your orders being rejected and the conflicting information you received regarding your refunds. This is absolutely not the level of service we aim to provide, and we truly apologize for the stress and inconvenience this has caused you.
To explain the situation regarding the refunds: the processing time unfortunately depends entirely on the type of order you placed because the automated system tracks prepaid, sim only, and phone orders differently and its specific status in our system. When an order is rejected during a risk analysis or due to address issues, the automated refund process can sometimes take longer than a standard manual refund, and it may take up to a few weeks depending on your bank (like N26) and our payment processor to fully settle. However, we completely understand that the contradictory timelines you were given only added to your frustration.
We want to get this sorted out for you as quickly as possible. Could you please send an email to webcare@simyo.nl including your personal details and the reference to this review? Once we receive your email, we will immediately dive into your case, verify the status of the €10, and ensure this is resolved properly.
Best regards,
Simyo Webcare
