Dishonest and fraudulent
Dishonest and fraudulent.
I believe they activated buitenland internetten in the app without my knowledge, perhaps by software update, and refused to cancel 60 euro incurred while on the plane, unwittingly somehow connected to a non-EU provider. They make money by trapping people into expensive calls or downloads.

Hi Mike,
Thank you for your review. I am sorry to hear that you incurred unexpectedly high costs, especially if you did not consciously turn on internet abroad or connect to a non-EU network, for example during a flight.
Costs for internet outside the EU are charged if your device connects to a non-EU network, such as at sea or on a plane. Therefore, it is important to keep your phone in airplane mode in this case.
An automatic warning is sent in case of high costs, and at €60.50, the SIM card is blocked for internet abroad. It is advisable to turn off the international options in your Simyo account before traveling abroad to avoid these costs.
Could you please send an email to webcare@simyo.nl with your personal details and a reference to this review? We would be happy to look into this with you to see if we can help.
Kind regards,
Simyo Webcare

Scam, no refunds
Scam. You pay 5 euros to get a sim, provide all details, and they send you an email saying you didn’t pass their verification. Then you lose 5 euros — no reasons, no refund. I texted them on whatsapp (they have no email support) and they can’t refund me without providing more information about me.

Out-of-bundle SCAM
As a new customer, DO NOT transfer your current number to SIMYO. Despite having an active and fully working contract, they cancelled my service during the transition period without any notice. As a result, they charged me out-of-bundle fees, and in my case I was billed €130 for just one day of usage.
This is apparently how they welcome new customers.

Never received the SIM despite them…
Never received the SIM despite them "sending" it to my house twice. Had to pay for 2 months plus one EXTRA month because of their "one month notice period" for a SIM I have never even physically saw. Greed

Hi Charl,
Thank you for your review. We are sorry to hear that you never received the SIM card despite two attempts and still had to pay costs, including an extra month due to the cancellation period. I understand that this is very frustrating.
At Simyo, new SIM cards are sent as standard letterbox mail within two working days of ordering, without track & trace. If you have not received the SIM card, it may have been lost in the mail.
Could you please send us an email to webcare@simyo.nl with a reference to this review and your personal details? We would be happy to look into what went wrong and see if we can do anything for you.

The worst provider for sim subscription
I have no idea to find this company rank as top1 for the best service with price of Sim Subscription in the Netherlands. They try to take all the chance to charge the cost without any possible negotiation. When you try to pay them but maybe you have a wrong transaction with less 0.06cent because of the conducting mistake, they will try to charge you extra fine because of the delayed payment for 0.06 cents in the above described condition. They doesn't thinking if the missed amount is caused from your rejection to pay. They just feel happy from your conduct mistake because there is chance to them for extra charge. How terrible service.

Very bad company with high abroad rates
Very bad if you travel. They charge the highest rates, and customer service is a joke. I already changed to another provider after such frustrating situation. It is not true they send SMS or even the rates are clear. I was treated so badly when I contacted CS for support. Very traumatic experience.

Hello Esraa,
Thank you for your review. Sorry to hear that your experience has been so negative, especially while travelling. We understand that roaming costs and how international usage is charged can be frustrating when it does not meet your expectations.
We aim to communicate our rates as clearly as possible. In addition, when customers arrive in a foreign country, we always send an SMS with information about the applicable rates in that country.
If you have any further questions, you can send an e-mail to webcare@simyo.nl, mentioning this review and your personal details, and we will be happy to look into it for you.

Very expensive outside bundle agreement
The customer service is okay. But prices outside bundle are outrageous!!
In April i used 1 GB outside the bundle and Simyo charged me 67 Euros!!
The bundle itself internet + calls is 5 times less (20 GB incliuded).
Also calls landline to other countries is very expensive!
So please be careful when using services outside the subscription agreement.

Hi Irena,
Thank you for your review. We understand your frustration about the high costs outside your bundle.
Internet usage outside your bundle, especially outside the EU, is indeed much more expensive and calls to foreign landlines can also add up quickly. In this case, it is important to keep an eye on the text messages. That is how we keep customers informed. You will receive a warning SMS at 80% and 100% usage of the bundle. A data cap is also available for the EU. Your internet then stops when your data bundle runs out.

Simyo partnered -AMP?
Led by lazy management and employees who can't use their own laptops to process government legal documents and finalize a simple order. I wasted my time, money, and energy for nothing.

Outdated gender specification
Cheapest and because of the KPN network one of the more environmentally friendly options. I just think it's very outdated to only be able to choose between being Mr or Mrs.
