You can download multibit for example on your device. You can import the private key to the multibit wallet and send Bitcoins from the multibit wallet.
I'm using multibit as an example here. There are many others including but not limited to mycelium,electrum etc.
And make sure you never give someone your private key.
While paper wallet it's free to make it has a few flaws which rarely happens but they exist. In the moment you are generating it, if you print it (as you will print it ,the private key, the hacker can access your printer memory if your PC is infected with malware). Beside that, to keep a paper clean for a long time (as that's what paper wallets are for) takes really good discipline , safe place where to put it and memory.
For 0.03 BTC which cost a hardware wallet like ledger I think we are more safe by using this one rather than paper wallets.
