Trouble downloading gta 5 for ps3

As the title suggests, I have been having issues. A week ago it went to 2 gigabytes then failed. Today it went to 4 and failed. For context I'm using a 30 gig sd card on my phone. I do this because I have better mobile Data then wifi for my computer, then i transfer the files via USB. I know my sd card is good due fo my downloading a smaller size games on it and filling it to full. Please help
