Xiaomi 17 Ultra’s satellite version has now received China’s Radio certification under the model number “25128PNA1C.” It was also previously spotted on the same certification site; however, that was the regular variant of the phone.
According to the listing, this version will support Tiantong-1 and Beidou connectivity for satellite calls and messages. It also has UWB (Ultra-Wideband) support for seamless connectivity across its ecosystem devices.
This Radio certification adds to the growing list of approvals for Xiaomi 17 Ultra. Previously, the global and Indian versions of the phone were spotted on the IMEI database with model numbers 2512BPNDAG and 2512BPNDAI, respectively. It could launch in China in Q1, 2026.
Xiaomi 17 Ultra specifications (rumored)
As always, the talk of the Ultra is the cameras. The Xiaomi 17 Ultra is expected to feature a quad-camera system with the following setup:
- Main: Omnivision OV50X, 50MP (1-inch sensor)
- Ultra-wide: Samsung JN5, 50MP
- Telephoto: Samsung JN5, 50MP
- Periscope telephoto: ISOCELL HP5, 200MP
If true, this would be the first time Xiaomi has used a 1-inch main sensor from Omnivision. It has a 1.6μm pixel size and 110dB single-exposure HDR, promising exceptional clarity and dynamic range.
The front could get a 6.85-inch LTPO OLED display with 2K resolution and ultra-narrow bezels, reportedly thinner than the iPhone’s. Powering it all is Qualcomm’s Snapdragon 8 Elite Gen 5, paired with fast wired and wireless charging, IP-rated water resistance, and a large battery.
Xiaomi is also expected to launch its first NAS (Network-Attached Storage) device alongside the 17 Ultra.
