Ultra Mobile $29 Plan Compared: 10GB 5G Tested—Unlimited Fun! We’ve spent weeks navigating the $29 Ultra Mobile plan, and we’re excited to share our findings. For just $29 a month, we’ve unlocked unlimited talk, text, and a hefty 10GB of 5G data—plus 4G LTE backup when needed. The SIM card kit arrived sleek and ready to go, making setup a breeze. After a month of heavy usage, we haven’t hit a single speed drop, and the 5G speeds have been impressive even outside urban areas. The plan truly delivers on its promise of "unlimited fun" without the hidden catches. While data is limited to 10GB, our multitasking needs have been met so far, especially with 4G as a safety net. If you’re looking for a budget-friendly way to enjoy high-speed connectivity, we’re impressed so far.
