BSNL's recently launched 4G service in India on the 700 MHz (n28B) band spectrum is not working on my Pixel 7/8 devices. The 700 MHz network connects fine on my other device, but the Pixel 7/8 fails to latch onto this premium band. I'm using BSNL's 4G service, and this issue is specific to the Pixel 7/8.

NOTE: n28 band has two categories: n28A & n28B, BSNL uses n28B.

**Steps to reproduce:**
1. Insert a BSNL SIM card with 4G access into the Pixel 7/8 device.
2. Ensure the area is covered by BSNL's 700 MHz (n28B) LTE spectrum.
3. Observe that the Pixel 7/8 does not connect to the 700 MHz band, it only connects to 2100Mhz Band 1.
4. Insert the same SIM into another phone (tested on Samsung Galaxy S23) and observe the successful connection to 700 MHz.

**What happened:**
Pixel 7/8 does not connect to BSNL's 700 MHz (n28B) LTE band, though other devices using the same network in the same area connect successfully.

**Expected behavior:**
Pixel 7/8 should connect to the 700 MHz LTE network as it is a premium band and available on BSNL's network. This should improve network coverage and speeds, as experienced on other devices. BSNL has deployed 4G only on 2 bands, Band 1 (2100Mhz) & Band 28B (700Mhz), Since we dont have support of Band 28B on Pixels, It renders phone useless as 2100Mhz does not have good coverage, but 700Mhz does. I don't know if n28B is restricted by software or not, please enable it if it's restricted by S/W.

**Device and Android version:**
- Device: Google Pixel 7 (GVU6C), Google Pixel 8 (GPJ41)
- Android Version: 15 (Feb 2025 Security Patch)

**Is this a security-related issue?**  
No.

**Note:**
I have verified that the issue is not with BSNL's network as the same network and band n28B connects fine on another devices.
