Oister has been great, quick and easy to switch to their service via digital sim card, it can be done in an instant, which is great if you have someone stalking your phone.

Rated 2 out of 5 stars

Below average and discriminating service.

Besides the below average coverage in the middle of the city, you need to know if you have several phones on one subscription (family subscription or whatever its called, I can't check anymore), then its ONLY the person who makes the account who can log in. If you're a spouse to that person, Oister has a new shiny system that makes sure you'll be treated like your spouses child. Not an equal paying costumer. Its one thing to create the account with nem-id, but not making it possible to log in without it, when there's multiple users, is just the most demeaning service.

Dear I.J,

Thanks for your review.

Although we do our best to provide good coverage on 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 masts or the distance to the nearest mast.


It is also correct that when you become a customer of OiSTER, you can only log in with the contract persons NemID/MitID. We are an online company and continuously develop digital initiatives that mean that we are forced to ensure that it is the right owners of the OiSTER subscriptions who log in to Mit OiSTER.

We have made sure to increase security so that we can look after our customers' data and information as best as possible, so I am sorry to read that you find this discriminating.


The best greetings,

Sofi

Disaster

As a customer for around 10 years I expected proper service.
I used to be happy with Oister until today!
I requested a number transfer from another carrier to Oister a week ago. According to the emails received from Oister the transfer was about to happen today. So far so good. I received email stating that the QR-code for my esim is ready and I can active it from mitoister but guess what. After logging into mitoister I realised that there is no QR-code at all and I am left without a phone. I tried reaching customer service via email, cued for over an hour on the phone without success. Ridiculous!!!
So far I’m left without a phone for 24 hours and counting!!!
What are you going to do about it? Simple sorry isn’t acceptable at all!

Dear Frustrated Customer,

Thanks for your review.

I'm sorry to hear that your experience with OiSTER has been so unfortunate - it's definitely not how it should be.

Normally, it will be possible to download the eSIM the evening before the number transfer, so you are sure that the eSIM is ready for use the next day.
However, I am sorry to read that is not the case here.

In this case, we would always recommend that you contact Customer Service so that we have the opportunity to correct this.

If you continue to experience problems with eSIM or your SIM card, I would recommend that you contact us on 70 31 30 70, where my nice colleagues are ready to help.


Best regards,

Sofie

Worst of the worst

The absolute worst experience I have ever had with a phone service provider.

Constant extra costs, long waiting times, incompetent staff who do not help you have waiting 40 mionutes on the line. Bad connection. Do not go for this provider.

Dear Odin,

Thank you for your review.

I'm sorry to hear that your experience with OiSTER has been so unfortunate - it's definitely not how it should be.

Like many other companies, we are often very busy at the beginning of the month, which results in longer response times to mail and the phone. However, we do our best to get through to everyone as quickly as circumstances allow.


Best regards,

Sofie

I have TRIED to pay them the montly…

I have TRIED to pay them the montly fees 3 times.
But they have a problem receiving money - as they now state on their website.
BUT... they then shut down my services!?
I have 2 phone numbers and a router through them - and they turn off my services because THEY can't receive money!?!?
At least leave my services open until you figure out things on your side!?!?
Unhappy!

Total chaos and bad treatment of the client

It's absolutely unbelievable.
This company is totally chaotic and without any control.

31-05 - I did the payment.
02-06 - they blocked my numbers because no payment.

Additionally in meantime they just increase the prices without any warning or information or agreement.

They expect payment in advance but it is not possible to check or guess how much You have to pay.
At the end of May You have to pay for June but You have absolutely no idea how much.

Hi Zdzislaw,

I am sorry to hear that you have had trouble with your payment!

Unfortunately, there has been an error in the redirect process to NETS where manual payments have not gone through.

On April 20, we sent out an email entitled 'New prices on your subscription from June 1, 2022' to all our customers.

You are always welcome to contact our costumer service on: 70 31 30 70 - where we can tell you the price of your subscription and help you with any other questions.

Have a nice day!

Best regards,

Hello Tarik

I am deeply sorry to read that you had a bad experience with us.

When you wish to purchase a phone at OiSTER and want to pay for it through installments you have to get an approved creditscore.
The score gives an amount that you can purchase hardware for. And the system might take a bit before calculating the final score.

We would love to help you get clarification regarding your current credit standing, and help you find a phone you like.

I can only regret that you got a bit diverted information in the startup.

Please don't hesitate to contact us by phone 70313070 or email: kundeservice@oister.dk

Best regards
Andrea

Hi,

I am sorry to hear, that you experienced our website during some technical difficulties.

That happens to the best of us. Usually we fix it pretty quick.

If it does last a couple of hours, please try entering the website from another unit or browser - that usually helps.

Nevertheless, our website is up and going right know.

I wish you a good day.

Hi,

Thank you so much for your review.

It is great to hear that you find our coverage usable and satisfying.

The prices on our subscriptions are definitely in the cheap end - we are also aiming towards being competitive on the price ranges.

Phone calls and sms/mms to foreign numbers are not included in your subscription. If you make phone calls or send sms/mms from Denmark to a foreign number, you will have to pay for these activities.

Unfortunately, it is not possible to include phone call or sms/mms from Denmark to foreign numbers in any of our subscriptions.

We would therefore recommend that you use Messenger (Facebook), WhatsApp or maybe Skype instead. It is completely free to call or sms/mms on these platforms - also when it is to someone who is abroad.

I wish you a wonderful day.

Best regards,
Julie
