Dual SIM Issue: Aqara Home app stuck at 0% when using two SIMs from the same carrier

Hi everyone,

I am having a problem with my Aqara G3 and G5 Pro POE cameras on my Samsung Galaxy S25 Ultra. Please help me.

1. My Setup:

  • Phone: Samsung Galaxy S25 Ultra (One UI).
  • Camera: Aqara G3 (using the Aqara Home app).
  • SIM cards: I use two SIMs from the same carrier (Viettel) at the same time:
    • SIM 1 (Physical SIM): Only for phone calls.
    • SIM 2 (eSIM): Only for 5G mobile data.

2. The Problem:

  • Wi-Fi: Works perfectly. I can watch the camera.
  • Only eSIM active (Physical SIM is OFF): Works perfectly on mobile data.
  • Both SIMs active: The Aqara Home app gets stuck at 0% when loading the video. I cannot see anything.

Is there any way to fix this network bug? I want to keep both SIMs active and use the Aqara Home app with full features.

Thank you!

Is this issue only happening when using the Aqara app or maybe also with other apps (like internet browser etc)? It seems like a system issue - like your phone is trying to use the SIM 1 for internet and it’s blocked (or limited to very slow speeds) and it fails.

My be there is an conflict on you network from eSIM as having 2 from the same carrier then only one can be used for 4/5G connection you need to check network configuration on you phone.also as @cezary806 sad try navigate or check others apps if they work too or will give you network issue or won’t load at all

Thank you.
All other applications that use internet data are working normally, including controlling the device via the Aqara Home app. Only the camera connection is failing.

I tried configuring it as the AI ​​instructed, but it didn’t work. The AI ​​concluded that the error was due to the Aqara Home app.

Pls see the video bellow:

Streaming connection is different than normal HTTP traffic (so webpages, other features of the Aqara app).

So maybe in this case it may be a combination of specific OS behavior/OS bug and Aqara app bug. In other words: it should work, devs didn’t suspect it wouldn’t work, but it doesn’t in your specific case.

We need the devs to reproduce the bug and say for sure if it’s fixable.

Weird did you check your coverage and speed?as it could be that you do not have enough speed to run all those cameras

@cezary806 This issue is very inconvenient to use. Do you know how to report it to the developer now?

@coccolino_26 I am sure this is not because of a weak internet connection. The proof is that in the video, when I turn off one SIM, I can watch the stream immediately.

Then if works with one e-sim could be that aqara see an conflict when both are enable.you could send an email to aqara support and explain them the issue with the 2 e-sim.

@Aqara_PM_Donie hello, It seems like you are a PM of Aqara. Could you please raise this issue to the Aqara development team for me? If not, can you share a contact point so I can do it myself?

Yes, I am arranging for an engineer to analyze the issue with your device. We may provide you with a new app version for testing. Are you currently using iOS or Android?
