Hi,I'm Miranda, and I'll be happy to help you with your question.
There are many websites that will allow you to purchase Bitcoins using SMS/phone payments. However, using your mobile carrier to make the purchase can be a very expensive way to buy Bitcoins. But if you keep your purchase small, you may decide that the convenience of using your mobile carrier to buy Bitcoins outweighs the higher cost.
Most of the websites that let you purchase Bitcoins with SMS/phone payments require you to send a text message or make a phone call to get the Bitcoins, but every site is different and has its own requirements.
Here are links to some websites that allow you to use SMS/phone payments to purchase Bitcoins:
