No voicemail notifications and some texts missing
I have an iphone X that I switched over from verizon a few days ago. Since switching I've either not received my voicemail notifications or have received them many hours late. Likewise, I can receive texts from friends but not from businesses (like notifications from my business' scheduling system). Long customer support call led nowhere. Changed sim card out today, which led to a dump of missed texts coming in but the voicemail issue was only temporarily fixed by dialing my own number. And now, an hour later, the texts aren't being delivered again.
The Xfinity guy suggested it might be my phone and I should consider getting a new one. That seems ridiculous. The phone was working great with Verizon three days ago.
