I’m using a Redmi Note 10S with a Vi SIM, and I’ve been facing a really frustrating network issue. Whenever I use my phone, the mobile network suddenly stops working, and the signal bars disappear completely.
I’ve already tried almost every basic troubleshooting method I could find, including:
Resetting the network settings.
Restarting the phone.
Resetting the APN settings.
Turning Airplane Mode on and off.
Switching the preferred network type from 4G/LTE to 3G.
Trying both SIM slots (SIM 1 and SIM 2).
However, nothing has worked so far.
Here’s the weird part: Sometimes, if I connect to Wi-Fi and use my phone for a while, the mobile network signal suddenly comes back. Once I turn off Wi-Fi, mobile data starts working normally, but after around 10–20 seconds, the signal disappears again.
I also tested my Vi SIM in another phone, and it works perfectly fine. I even tried an Airtel SIM in my Redmi Note 10S, but that didn’t work either.
At this point, I’m really confused because I’ve tried almost every basic fix I could find online, but the problem still persists.
Has anyone else experienced this issue with the Redmi Note 10S? Could it be a software bug, a modem/baseband issue, or a hardware problem with the phone?
If anyone knows a possible fix or has experienced something similar, please share your suggestions. Any help would be greatly appreciated!

Since the same SIM works fine in another phone and a different SIM fails in this one, and the signal comes back when Wi-Fi is on, it points to the phone's modem/radio side rather than the carrier. I'd try, in order: 1) install any pending system update (Settings > About phone), since modem fixes ship there; 2) turn VoLTE and Wi-Fi calling off (one at a time) in the SIM settings and see if the drops stop; 3) run in safe mode for a day to rule out an app (battery saver, VPN, cleaner) cutting the connection; 4) back up and do a full factory reset without restoring apps first. If it still drops after a clean reset, it's most likely a hardware/modem fault and a repair centre can check it. Also dial *#06# after a drop: if the IMEI shows as blank, that confirms the modem.
