    5g fine upstairs, meh below

    Basement kitchen dropped to one bar and pages crawled. Upstairs hit full 5g and streamed football without stutter. That flip is annoying, though expected in our area.

    Cheap plan that works

    Porting number took a day and the SIM activated straight away. Data speeds are solid in town. The portal is spartan but does the job. Great price.

    Eu trip went smoothly

    Roaming set itself up on arrival. Data cap was clear in the app and support confirmed fair-use limits on chat. No shocks on the bill later.

    Signal held on the bridge

    Streaming a match crossing the Storebælt, I waited for the dreaded buffer. It didn’t come. I grinned at my lucky timing.

    Easy switch from rival

    I ported my number in two clicks and the SIM came the next day. Activation through the self-service page was straightforward and the usage dashboard is clean. The only learning curve was finding the roaming toggle, but the guide explained it quickly. Speeds have been consistent for streaming and tethering. Feels like a smart, no-fuss choice.

    Good value mobile plan

    SIM arrived fast, coverage solid in Copenhagen and on train rides. Felt reassured by simple app usage and clear data counters.

    Roaming issue handled

    Chat took a few hours, but the agent explained EU roaming fair use and refreshed my line. Data started working again properly.

    It took several days to get the SIM card.

    It took several days to get the SIM card. When it finally came and I put it in my phone, it didn't work right away. I couldn't make calls or use the internet. I had to use another phone to call them and waited over 30 minutes to reach customer support. Not a good start 😔 Sadly, the low prices come with poor service

    It's decent. It doesn't include non-EU countries

    It's decent. It doesn't include non-EU countries like Switzerland or Monaco, which is a letdown. My friend had a different SIM that covered all those places, so we had to rely on his internet while traveling. Also, even calls within the EU drain the balance in no time. I'm considering switching to a SIM that offers more country coverage for affordable internet outside the EU.

    This company's service is very good.

    This company's service is very good. My problem was I used the wrong router, not 5G, just 4G. Now with Oister's 5G router, all's well. I'll suggest Oister to others to make up for my past errors.

    Pleased with Oister for Mobile but not happy with

    Pleased with Oister for Mobile but not happy with Oister Wifi. We live in Copenhagen and can see the cell antenna out of the window where the 4G router is. Yet, highest speed ever was 80Mbps on a good day. Additionally, connection resets many times daily, making working from home very unreliable. Happy 6 month binding period over so can go back to cable internet.

    The company is good

    The company is good, you know? It's not too expensive, it's practical, and it just works. Even when I go on long trips in the EU outside of Denmark, my OiSTER account stays strong. The coverage is great everywhere. I've been with them since November 2019. I tried another company once, but I came back to OiSTER.

    5g zum kleinen preis

    Online angemeldet, eSIM in Minuten aktiv. 5G ohne Aufpreis in Kopenhagen richtig flott. Familienrabatt wurde automatisch erkannt. Positiv: klare App, Datenverbrauch gut sichtbar.

    Günstig und erstaunlich stabil

    Online-Anmeldung war flott, SIM kam fix. Netz ist in der Stadt stark, 5G ohne Aufpreis super. Im Wochenendhaus schwankt es, aber nutzbar. App für Daten-Add-ons ist logisch. Für den Preis sehr zufrieden.

    Einfache bestellung, gute deckung

    Erster speedtest am hafen

    Ich drückte auf Start, 5G ploppte auf. 120 Mbit, wow. Kurz gejubelt, dann innerlich genickt. Später im Zug etwas schwankend, aber noch ok.
