Shout-out til Oister support der reagerede prompte og professionelt på min henvendelse

Happy with Oister as a provider for Mobile but the Oister Wifi is very disappointing. We live in Copenhagen and I can see the cell antenna out of the window where the 4G router is. Still, the highest speed I ever got was 80Mbps on a good day. On top of that, the connection resets multiple times per day, which makes working from home very unreliable.
I'm happy my 6 month binding period is over so I can go back to internet via cable.

Affordable, practical and it just works, even in long term trips in the EU outside DK, my OiSTER account holds strong, great coverage all over. I've been a customer since November 2019. I once switched to another company but came back to OiSTER.

I must apologize to Oister for my previous posts. The service is really excellent, and my mistake was that I abandoned the 5G router and used a regular one, designed only for 4G. Yes, I switched to another provider, and when I received their 5G router and inserted an Oister SIM card into it, everything worked perfectly. I will now recommend Oister to everyone I know to at least somehow atone for my guilt for my previous posts.

Oister has provided me with stable and reliable coverage for my needs. However, they are not the cheapest provider out there, and they require NemID to log in to the self-service portal, which is unnecessarily inconvenient. Overall, I am satisfied with Oister, but they could improve by offering a more competitive price and making it easier to log in to their self-service portal.

Easy transition from another company. Easy to switch over to roaming when i travelled.. it was super convenient. I highly recommend oister.

Improper antennas in some areas and low bandwidth and slow internet speed and internet outages, as well as not providing mobile phones in installments to regular customers and extreme strictness in providing mobile phones

Oister is the BEST
I have 2 Oister agreements and would never consider another Vendor. They always make it totally easy to deal with them and their online solutions are 100% the best in the business. From an internet user since 1992.

Oister informs you according to the last periods, if its convenient to change your phone plan.

You are always in touch with the customer. You always send information or sales and other offers when necessary. And you are reachable on phone all the time.

Subscription bundle unclear.
Free talk does not mean free talk at oister!

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.

Reply from OiSTER
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.

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!

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.

Oister failed to deliver sim-card to me after 3 requests. I am new customer and still waiting for it...

Reply from OiSTER
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.
