About this app

Let's try Radosť, a digital in-app operator, with the first 7 days for free.


You don’t have to go anywhere; you just need to download the app and follow the simple step-by-step setup. You will need your credit/debit card and your ID card, so we can be sure that you are really you.



Let us introduce ourselves a little:

🌐 We operate on a great 4G and 5G O2 network.

🦄 We are completely commitment-free.

🥳 We have 4 awesome tariffs, so you won’t get dizzy from a complicated offer.

💸 Payment is automatically charged from the card you add into the app.



You set it up once and enjoy your Radosť. If you feel like you have too little or too much data, minutes, or messages, you can simply change your tariff according to your current needs and spending.

That’s enough about us; let’s go and make you happy with Radosť! 😊

Help chat full of bugs, ENTER sometimes send message and sometimes goes to new line. If you switch from chat to scan ID, chat session is auto terminated. Same light condition, position and camera yet back of ID is ok and front always throws error - repeat. Process is not streamlined for web only operator and basically you are left with only one option: fill out the form so they can send you SIM via courier service. That is not "online only" unless pizza ordering is in the same category.

Ahoj. Skús, prosím, aplikáciu odinštalovať, reštartovať telefón a znovu stiahnuť. Ak to bude pretrvávať, napíš nám, prosím, na chat na našej stránke. Vera

Not possible to sign up for a service. Registration keeps failing. Hours invested in trying to resolve this through chat - no results. No one knows what is the issue, no one competent to help. Shame for all the time wasted trying to order a simple prepaid SIM. Radost? More like Utrpenie. Diky za nic. @Ivan, I am so "thankful" you are suggesting a solution, none of your colleagues have ever come up with. If it was this simple I think in 3 weeks we would have solved it? Just sad.

Ahoj. Ak sa ti nepodarilo zaregistrovať prostredníctvom overenia v aplikácií, stále môžeš zvoliť možnosť overenia pri doručení, teda pri preberaní zásielky. Ivan.

It is not possible to register, or at least to do it easily. Have tried to make a photo of my ID, with good light, with bad light, on a white background, without background, spent 5 mins with no success.
