Original story (published on August 19, 2021) follows:

Google Pixel 4a 5G came out in November 2020 with Android 11 out-of-the-box. The mid-ranger from the Pixel lineup is now in line for Android 12 which will come out in September.

However, owners of the Pixel 4a 5G have been facing some connectivity problems after the latest security update.

Google Pixel 4a 5G

As per several reports from the Google Support community, the SIM card is not getting detected properly on the Pixel 4a 5G after the August security update.

User reports outline that the Pixel 4a 5G is detecting the SIM card carrier but not connecting to the network. Also, the same SIM card works in other devices but not in the Pixel 4a 5G.

This problem is inconveniencing many which further indicates that it might be widespread. Moreover, the culprit behind this issue appears to be the August security update.

After security update the sim cards aren’t getting detected for pixel 4a 5g

Sim Card not being detected Tried rebooting, re slotting the card and airplane mode. Help Needed


However, nothing is clear as of now because Google is yet to make any comments on the matter. Users have tried generic troubleshooting like resetting the network and device to no avail.

Even tweaking the preferred network type and manually selecting the network is not helping users of the Pixel 4a 5G.

However, it is possible that a fix for the Pixel 4a 5G problem where SIM card is not getting detected properly might arrive in the near future.


This is because a Google Support community Product Expert has escalated this issue to the relevant team.

Thus, a future update for the Pixel 4a 5G might fix this problem and get the SIM cards working again.

However, all this is still based on speculation until the tech giant makes proper announcements regarding the issue.


That said, we will keep tracking this for further development and will report back when more details become available.

Update 1 (November 25)

The November patch has rolled out to Pixel devices but still, affected users are still reporting that the issue continues to prevail.

So, just installed November security update and…nothing. This is ridiculous. This is software issue, that occured on so many devices lately and in past as well, why is there no fix? For me, my 4a was first really pricey phone that I ever bought, I always had secondhand or cheap chinese ones. Now I have nothing, but regrets. I know that for somebody 400$ isn’t much, but for me, it was lot of saving.

Update 2 (January 17, 2022)

Fresh reports are still coming regarding this issues which means that it still persists and not resolved even in the latest January patch.

So, out of the blue one day, my phone has a message on the lock screen me there is no SIM card and that only emergency calls will go through. I tried rebooting and pulling out the SIM card but that didn’t work. Any help would be great. (Source)

Update 3 (October 7, 2022)

10:03 am (IST): Some Pixel 4a users are still complaining about the SIM card detection bug which suggests that the issue persists even after Android 13 update.
