I haven't heard of such a service before , but from a search I did , I found Fortumo h**ps://nuvei.com/apm/fortumo/ . From what I can see , they offer services in Europe. I'm not certain if that's what you're looking for , but I hope it helps . May I ask why someone would prefer that service over others ?
Because it way easier and you pay your phone bill monthly even 2 months, also this is going to be, next way if sending small amounts of btc or whatever coin, they work on it. In some countries like in India or Africa thats the way they buy coins, idk exactly how they named it but for btc will be i think micro transcactions. I have buyed many times this way from daopay, they worked with coingate, but now services most of them aren't working, and also atm id rather spend some cash which i can pay later, than pay now,its good way, when u want to buy, but don't have in cash. Fortuno doesn't work too for me because they provide for only one phone company
