Dear Valerie,
Thank you for your review.
We offer free calling within Denmark when you are in the EU, both to Danish and European phone numbers. However, if you make calls from Denmark to international destinations, you will be charged for this.
I have sent an email to the one you provided, as we have requested more information from you.

Everything is pretty good, but trying to get in touch with them is quite impossible. 45 min. on the phone and I got tired of waiting someone to pick up. Just don't offer phone support if you don't have people on it. Is it that simple.

Dear Mihail,
Thank you for your review.
We have been exceptionally busy lately, and as a result, we are in the midst of the recruitment process to bring on new colleagues. I understand that the wait times in our customer service and the lack of an opportunity to speak with a representative promptly have been frustrating for you.
We want to be in contact with our customers just as much as our customers want to reach us, and therefore, we are aware that this is not a sustainable situation.
If you still need assistance, please feel free to write to me at trustpilot@oister.dk, and I would be more than happy to look into your case.

The SIM card did not arrive so…
The SIM card did not arrive and so I managed to solve the problem by creating an e-sim, before that I tried to get in touch via phone but due to waiting for 45 minutes I ended up giving up the subscription too. I still haven't fully understood this mystery of the card that never arrives, I worked at Postnord and they are super effective and serious, they would never throw the cards in the trash. If the cards are not delivered, look for other transport companies that are committed to delivering the cards on time. I tried to be your customer but unfortunately it wasn't this time.

Dear Sidnei,
I'm sorry to hear that your experience with OiSTER has been so disappointing - that's definitely not how it's supposed to be. If it took such a long time to receive the SIM card we sent, I can understand your frustration.
I understand that it can be frustrating and inconvenient to be without a phone for such an extended period. I would like to investigate the situation and assist in resolving this issue as quickly as possible.
We send an email when the SIM card is dispatched, wherein we mention that you can expect to receive the SIM card within 2-5 business days. If you haven't received the SIM card within this timeframe, you should reach out to our customer service.
With that being said, I can understand your disappointment in not receiving your SIM card in a timely manner! It's definitely not our intention for our customers to end up without a SIM card.
We send out many SIM cards every single day, and it's incredibly rare for the SIM card not to arrive on time!
Could I ask you to send me an email at trustpilot@oister.dk, so I can check your order and make sure the SIM card is being sent to you? I'd also like to ensure that all necessary steps have been taken to avoid a similar situation in the future.
I look forward to hearing from you!
Best regard,
Sofie
When I was looking for the internet
When I was looking for the internet, I found Oyster. I've checked the speed of the internet and there was up to 500 mb per second, but now it's no more than 2.5 mb per second. Can you, please, explain why have I paid for the normal internet but got the worse one? Sorry, if it is too aggressive, but that's awful!

Dear Космический Чебурек,
Thank you for your review.
It is correct that by using our 5G network, you can achieve download speeds over 500 Mbps. This requires using a device that is compatible with the 5G network.
If you have purchased an OiSTER WiFi subscription with the Huawei B535 router, it will be possible to connect to the 3G and 4G networks, along with the corresponding speeds of these networks.
Firstly, signal strength plays a significant role. If your device is far from the nearest mobile tower or in areas with poor coverage, it can affect the quality of the connection.
Additionally, network traffic load can vary throughout the day. During periods of high traffic, such as rush hours, multiple users sharing the network can result in slower speeds and instability.
Weather conditions can also impact the connection. Extreme weather conditions like storms, rain, or snow can temporarily affect the functioning of the mobile towers, thereby diminishing performance.
Lastly, building structures can also have an impact. Materials like concrete, metal, or windows with metallic coatings near your device can block or weaken the signal.
I would be more than happy to look into your case if you would like to reach out to me at trustpilot@oister.dk. Once I receive your email, I will be glad to further investigate your challenge.
Looking forward to hearing from you.
Best regards,
Sofie
I'm very happy with OiSTER
I'm very happy with OiSTER. I have basically nothing to complain about: it works, it's cheap, there are no surprises. They are still the best value provider I have found in Denmark. They used to have some limited reception issues, but not anymore. Speed and reception are good nowadays. The only reason it's not 5 stars is that abroad there is often limited reception and network speed.

Never got a sim card
After two attempts and a month of waiting to get the sim card by mail I decided to switch to another company. Got a sim card from another company in 2 days. Now I regret even trying OiSTER because I spent a month paying a lot of money to use a phone service from my home country while waiting for a sim card.

It's okay
It's okay . it doesn't cover non EU countries like Switzerland Monaco etc. Which is not nice. My friend had another sim which was covering them all and we had to use his Internet when travelling . even calls in eu makes the balance go 0 in two minutes. I am thinking to switching to a sim with most countries coverage for cheap Internet in non eu

Dear Sara,
Thanks for your review.
It is correct that OiSTER does not offer international telephony in countries such as Switzerland, Monaco, etc.
You are also right that it costs money to make calls abroad from Denmark. If you are staying in a country with which we have an agreement, it will be possible to call other EU countries without being charged extra for the call. Therefore, you would be able to stay in Germany and make a call to a Spanish phone number for free.
If you are in doubt about what is included in your subscription, please do not hesitate to contact us on 70 31 30 70.

I have been a loyal customer for over a decade, now it’s time to say bye.
After being a loyal customer for over a decade I have had it!
I was traveling to Türkiye and within 40sec from arriving I had used for 1000 DKK data (my boyfriend and I literally just opened our phones!!).
When I go to my subscription page it says that “Udenlandstelefoni med data” is included, but apparently it only means that your phone can work all over the world, nothing more than that. But I was not even able to send a text when I arrived, but you made sure to charge me for those two unsuccessful send texts (thank you!)
They only provide services when you are within EU.
This story I s even more ridiculous, because I was in Israel back in 2019, with no issues at all (and no, customer support person, I was not on Wi-Fi the whole time). As I did in Türkiye, open my phone at arrival and the whole week my phone was working and there was no extra charge when I got home.
So I was surprised and baffled that because I travelled to Türkiye I’m being charged an extra 1000 DKK within the first 40sec after opening my phone upon arrival.
Why is there such a huge difference between Türkiye and Israel - they are both out side of EU.
Please make it super clear for your customers that they can only use data within EU, and good luck trying to travel outside of EU and using your phone.
You have lost 4 loyal customers, who never experience any issues, but this is just too ridiculous and no help from your customers support. I have had it.

Dear Xenia,
Thank you for taking the time to share your feedback with us.
We apologize for any inconvenience or confusion you experienced regarding the charges during your recent trip to Türkiye.
We understand that it can be frustrating to encounter unexpected charges while using your phone abroad. We would like to clarify that our "Udenlandstelefoni med data" service covers usage within the European Union. For destinations outside the EU, such as Türkiye, different rates and conditions may apply.
At this link, you can see our prices abroad: https://www.oister.dk/globalassets/filer/oister-priser-i-udlandet-21-12-2022.pdf
We strive to provide clear and transparent information to our customers, and we always advertise that there is a certain amount of GB data on the subscriptions that can be used within the European Union. Furthermore we always recommend that you check up on this before you travel from Denmark.
If you have any questions regarding this, or have more details in this case, please contact us at: Trustpilot@oister.dk, and I will be happy to help you.

Dear Monika,
Thank you for your review.
Although we strive to provide good coverage in our network, it is unfortunately not always possible to achieve broad coverage in all areas. There can be several factors that affect the quality of coverage, such as terrain, the number of transmission towers, or the distance to the nearest tower.
In your case, it may indicate that the tower is overloaded during evening hours due to high activity. There are some settings you can adjust on your router that we could try.
I would really like to take a look on your case. Therefore, I hope you will email me at trustpilot@oister.dk with your inquiry. Once I receive your email, I would be happy to look into your challenge further.
I look forward to hearing from you.

Have very bad experience with OISTER.dk
Their payment system is completely messed up and you can't get either a registration or account number for their van, so you can transfer money manually if you don't have the option to pay via MobilePay.
However, they also allow you to close your subscription and when you need to call e.g. the municipality or another public body, it will be called up by their customer service. And you close your subscription without giving notice. It is very cross-border.
For me, it has had economic consequences, as I had a telephone meeting with the municipality, which I could not hold because of this..
Cannot recommend OISTER.dk to others..
