Duo 2 Android 12L breaks calling

Anonymous

Since the Android 12L update, I have not been able to make or receive calls. Incoming goes straight to voicemail and outgoing immediately ends calls. Carrier is T-Mobile. I suspect the issue is the same at what happened with the AUS phones as listed here Android 12 Breaks Calls — ZenTalk (asus.com)

This required an update to get the calls working again. Is there such as update in the works as right now my due 2 is just a tablet that cannot make calls.

Everything else works btw even calls with WhatsApp and teams

    You do NOT need active service from the different carrier for this workaround to be successful. You need Android to run the Carrier Provisioning which cannot be kicked off manually by an end user. Inserting ANY non-TMo SIM, active service or not, will kick off carrier provisioning when swapped in. It is only for 1 boot and then switch back to your active SIM from T-Mobile.

    I understand. But a Verizon sim with Verizon service. Not prepaid. Service is what you need. Pple may think they are the same but prepaid is not a full service. It like TMobile and metro. They say it the same but ur not getting the full bandwidth or the right apn. Needed to work properly. Ver. Opens up the bands needed for the T-Mobile sim to access . Full service not prepaid.

    Here's the thing...

    The first time I switched the SIM, it was with an active SIM from a phone; the girl at the cell phone counter at Best Buy let me use her store phone for this, when I explained the issue. I bought the non-active SIM just in case the issue cropped up again.

    Which it did.

    So using an active SIM didn't permanently fix the issue, and the duration of the "fix" has been the same, with both the active and non-active SIM.

    You are missing the point of the issue. T-Mobile SIMs stop working, likely due to a carrier config being pushed when T-Mobile identifies the Duo 2 as a Surface 3. The only way to reset the config temporarily is to insert another carrier's SIM. This runs the local Android carrier provisioning for the different SIM. Then switching back to your normal T-Mobile SIM runs carrier provisioning again since carriers were "switched".
