Global GSM SIM: Hangouts can't receive GV call on data
Use FP Global SIM card on my OnePlus phone. Got data service, able to access internet on data. And the FP messaging app works fine too. Only my hangouts can only make outgoing call, unable to receive GV call on data. On WiFi hangouts can make and receive calls. So Hangout settings and my GV account is fine. And top-up my GV credit doesn't help. I also tried to reset my phone network settings, reinstall hangouts/dialer. That didn't help either. Any thing else missed here?
