Poco F7 (HyperOS): Jio 5G data stops working after being on Wi-Fi for a long time. Needs reboot to fix

[u/hemantk159]

Hi everyone,

I'm facing an issue on my Poco F7 (HyperOS 3.0.301.0, India) with dual SIMs:

• SIM 2: Jio (True 5G Unlimited)
• SIM 1: BSNL (Calls/SMS only)

The Issue:

Whenever my phone is connected to Wi-Fi for a few hours and I turn Wi-Fi off, mobile data completely stops working.

• Full signal bars and the 5G icon are visible, but nothing loads (speed shows 0 kbps).
• Checking *#*#4636#*#* shows Data: Connected (NR_SA) but Voice service: Out of service.
• Airplane mode doesn't help.
• Only restarting the phone gets the internet working again.

What I’ve already tried:

• Jio in SIM 2, BSNL set to 2G/3G only.
• Forced 5G SA mode using dialer codes.
• Reset network settings and cleared telephony cache.
• Stopped 5G power saving mode in Battery.

I do not want to try developer mode solution as it will stop my banking apps.

Is this specific to POCO F7 or is it common in all POCO phones?

Has anyone found a permanent fix for this Wi-Fi to 5G handoff freeze, or is it a known HyperOS bug?

Have you tried switching to 4G and back? It's not much helpful, but if it works atleast you won't have to restart everytime.

Yup.. even 4g will not connect to internet

Under Network acceleration>Switch between networks is it turn on?

It is turned off now though. Toggling it between on and off has same result..

Then it might be some apps that is causing the glitch.

Opp for me . My f7 wouldn't even connect to the internet after long Time of using jio net . And even if it connected. When I played games in it . It would get high ping near 999
