Main page not loading

Main page not loading, can't make actions, always have to reload the page - and even then, it's not guaranteed that works at all -, can't activate eSIM and not giving any explanation, why.

Poor product

The E-sim hasn't worked (error in the QR code) despite it getting activate by the team and being refreshed / reordered more than 6 times! And the actual physical SIM card hasn't arrived within the promised time.

Oister has good deals, for new customers

I have always liked oister, I'd been with them for a long time, however I saw a lot of significant discounts coming to new customers and nothing to us long time customers, so I switched until I saw a new deal for new customers that had what I wanted.

I've been very happy for over a year now, so I'm getting an additional subscription. However, there's something they need to fix - their bonus app doesn't count my bills and I'm not accumulating bonus points.

Quick and easy

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.
