Surface Duo 2 on Tmobile can't make phone calls "server error"

My original Duo 1 worked great on tmobile. My new Duo 2 gets a "server error, please try again' whenever I try to make a phone call while connected to LTE or 5G. If I bump the preferred service down to 3G then phone calls work fine.

Is anyone else using a Duo 2 on tmobile in the US? Any similar issues?

Just replacing my SIM didn't help. Finally talked to a phone guy at Best Buy who tried putting his personal Verizon SiM into my phone. we could see the DUO 2 was on Verizon's network. then we popped my TMO SIM back into the DUO 2 and magic - phone calls worked. So somehow this updated their network to maybe recognize that my SIM was associated with a new device? anyway glad to have it working again and loving the DUO 2.

    I meant the phone won't activate on the network. They are getting foreign android device. I called t-mobile cust care by chance someone ran into this already. I read Imei # and said no you can't bring it on to the network. Tomorrow I will visit Att see if they take phone and port my number over.

    They don't have to activate it.. Just put your old tmo sim in the duo and it will work...
