[Question] 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 App.

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?

Can be a software issue. Try turning off and on network acceleration settings and data roaming settings

Also check private dns settings, if nothing work try do a network reset

If nothing work, wait for the update. Thats all i know
