Hello, dont you know way to buy bitcoins by SMS ? I would try it, I found few webs, but I don't want to try it when I don't know anything about them. So if you can say me about some trust web for do it. Also I need to do it with O2 operator, from Europe.
Do you realize that even if you find some legitimate service of that type and you won't get scammed fees of the SMS buying/paying services are insanely high. You will pay more than 1/3 of your SMS cost as a fee to mobile operator. If you would buy that way you will lost some money in a process. So avoid this at all cost. Your best bet if you don't want to use exchanges is to use localbitcoins service.
