Charged 70€ for “roaming” I never used
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.

Hi Emily,
Thank you for your review. We understand how unexpected charges can be upsetting. However, we want to clarify that it is not possible for data usage to occur when your phone is in flight mode with roaming turned off. The charges you incurred indicate that your device did connect to a network outside the EU, likely around the time you landed and powered your phone back on. It's possible that the usage was huge in a short amount of time and thats why you probably got the message straight away.
We would like to investigate this further. If you can provide us with the time of your flight and when you turned on your phone, we can verify the moment your device connected to the network and confirm the usage details. We can see when you used data on your account.
Please contact us at webcare@simyo.nl with this information so we can take a closer look and can also see if we can do something about the costs.
Kind regards,
Simyo Webcare

very unprofessional customer service
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.

Hi Calvin,
Thank you for your feedback. I understand you feel frustrated. If your roaming is turned off, you can still call abroad because you are in the Netherlands so therefore you are not roaming. This can be confusing, but you can always check the rates on our site if you are unsure about the costs.
We do take your feedback into account and will work hard to improve our services.
Kind regards,
Simyo Webcare

Hidden fees and NO refund: avoid this service!
I went just one minute over my call allowance and immediately received a bill of nearly €40—with no prior warning that my minutes were running out. I only discovered it the next day. Absolutely outrageous!
I contacted the company, expecting some understanding or goodwill, but they refuse to issue a refund. This is completely unacceptable.
Do not subscribe to this service. They charge hidden fees and show zero customer care.
I request a refund for this criminal charge.

Okay provider, but greedy monetization schemes.
Okay provider otherwise, but in my opinion it's predatory to charge for a data limit. Do not trust them to keep your best interests in mind. My wife turned off her data as soon as she got a notification that she was over her bundle, and now she's paying a significant portion of the monthly cost for the measly 56 megabyte of data that she went over. If you don't want it to happen, you have to pay them an extra charge monthly. I'm sure that technically, this doesn't cost them anything. Seems like a bit of a protection racket.

Hi Pepijn,
Thank you for your review.
We understand that unexpected charges can be frustrating. At Simyo, we work with a clear bundle structure: if you use more data than your bundle includes, out-of-bundle charges apply. To help prevent this, we offer the feature of setting a data limit. This option is available so customers can choose what best fits their needs.
If you would like us to take a closer look at this situation, feel free to contact us at webcare@simyo.nl

Hi Vico,
Bedankt voor je review. Fijn om te horen dat je bereik goed werkt in Nederland!
Als je in het buitenland bent, is het soms zo dat je handmatig een netwerk moet selecteren in je telefoon voordat je verbinding werkt: https://www.simyo.nl/klantenservice/toestelhulp/netwerk-handmatig-selecteren.
Mocht dit geen verbetering hebben opgeleverd, neem dan gerust contact met onze klantenservice op. Wij helpen je dan graag verder hiermee!

Good quality, good prices
I've been a Simyo customer for about 10 years. Quality is very good, user experience has been steadily improving as well. Prices are great too.
The only downside is the rather complicated system of accounts and contracts. I just ordered a new number, for my daughter. She just needs a number for now, no mobile internet and almost no calling. I ordered prepaid. While ordering, Simyo told me we can get 10 euros each if we make up a family. We do, so I tried. Nope, it turns out you can only get family account if you order Sim Only, not Prepaid. Not only can I not get that 10 euro discount for each of us (but they did promise 5 euros off the first invoices, let's check), but I cannot manage her contract either. I hope I didn't misunderstand them. But if I did, it only proves my point ))

Hi Konstantin,
Thank you for your review.
We are happy to hear that you've been a loyal customer for so long and that your experience with us keeps getting better. This is what we do it for!
In your review, you mention our "Vriendendeal". You will only receive a €10 discount if both you and the new customer have a Sim Only plan. If one of you has a Prepaid connection, the discount will be €5 per person. So you and your daughter are indeed eligible for a €5 discount. 🙂
You can find more information about this on our website: https://www.simyo.nl/vriendendeal
