前几天在坛子里看到有人说国行1520可以上电信4G,但只能上网,不能打电话、发短信。这是由于现在电信4G只支持数据业务,打电话发短信要回落到3G,而1520不支持电信2G3G。 电信VoLTE很快就要商用了,有的城市已经试商用了。哪位大侠知道1520/930/830是否支持电信VoLTE?

借用一个老外的尝试,你看看吧,懒得翻译了。
I have been talking with numerous persons on this issue.  I can confirm that to Trigger VoLTE is entirely up to Phone manufacturer only.  Carrier support is the second part which can be done only if Phone manufacturer allows.  I tried my hands on Nexus 6P & found that there is Switch to toggle to activate VoLTE but is not activated by the manufacturer (Google).  You can confirm this by 'Googling' or 'Binging' for the yelling which people are doing for activating VoLTE on Nexus 6P.
I also tried my hands on Lumia 1520 by changing VoLTE support SIM.  I was able to see IMS setting and when I tried to click there, I got message that it’s not allowed.  In the same phone with another Carrier SIM, I am not able to see this setting.
To sum up, VoLTE needs to be first activated (ALLOWED) by Phone manufacturer followed by Carrier.  Unless Microsoft 'allows' to toggle VoLTE, Carrier CANNOT do anything despite of their willingness in doing so.
