Hello Team,

After the recent update I am unable to make or receive calls from sim 1. I can use the internet, see network strength it's all good but the incoming and out going fails. I reset network settings, rebooted the phone but the issue persist . When I switch the sim to ssim tray 2 , it works. What's going on here? Did you guys cripple sim 1 tray??



  • Is anybody going to respond what's going on?? It looks like volte in sim tray 1 is disabled after update.

  • Both sim trays work as Volte. I have my Jio on Sim1 and it works. Probably you might need to see some settings that is probably disabled.

    Try turning on the 4g option that i shared here in the picture.

    If it still persits try doing a factor reset.

  • I did a network reset but issue persist. I got alot of data in my phone and I don't want to perform factory reset. The settings seems to be the same tho.

  • Here is a replica of the problem that you mentioned and the solution to fix it.

    Hi Kamal7hydra,

    I had a check with the videos shared by you and another user, tried duplicating the issue. The calls work without even enabling VoLTE. I will forward the issue ahead.

    Also, as you mentioned you can't factory reset. I will check if there is any known issue here.

    Can you check if there is something to do with the hardware:

    How to Enter SMMI_TEST (test hardware)

    Go to Calculator=>type " .12345+= "

    you will be entered to SMMI_TEST

    Have you tested a different Network provider SIM in SIM 1 slot?

    Smmi_test for sim1 is working fine when I tested it. Also, I only use one network so I don't have any other. When the same sim working on sim 2 I don't think it would be necessary to use a new one. Also, when I move the sim to tray 1 the volte symbol never comes but works in sim 2 tray. This all happened afer the recent update. No issue with the tray or sim. It's a firmware issue .


  • Any update? Why don't you guys release an hotfix or something soon to fix this.

  • Still waiting. Did you guys figure out anything?

  • Even after a factory reset the issue persist. You support asking me to take it to a service center which is 100km away from my home. Don't you think this is BS?? It's a software issue!! What else you need? Is anyone going to answer me or not??

  • To make it simple. In sim 1 the LTE symbol is not there but it appears in sim 2. This happened after software update. Can I get some answers here please? Don't make users regret buying your devices.

  • Help me to downgrade my firmware. Send me the zip file to flash an older firmware. Atleast can you do that??

    I realise that you have probably tried this but try toggling the Sim one of then on again

  • Tried swapping, done everything. Nothing works. A newer version or an older version should work. Can anyone from asus help me to roll back to older version?
