I have used my Bitcoin to buy cellular load and paying my utility bills. I also used my Bitcoin to buy game credits like steam
I guess we are using the same exchange or Bitcoin wallet then. I am using the services of coins.ph and I am also doing these things too but the things is that they are not really accepting bitcoin directly. Coins.ph accept your bitcoin payment and then transfer your payment not as a bitcoin but as a fiat. The same as Steam since they are not really accepting bitcoin now due to it's volatility and fees.
