Hey all,
Over here in Australia (imagine in USA and a few other countries), the 3G/2G mobile networks are being shutdown. My carrier Vodafone is gradually shutting its down with Dec 15th 2023 being the final closure date. The 4G network will have VolTE but my device (LG V20) does not appear to support VolTE nor does it look like i can update the firmware easily (if at all) to do so.
Anyone else have this issue with their phone? (i realise it will be older ones)
Question about VolTE though - will sms and standard voice calling still work on 4G on my device or similar devices without VolTE ?.
thanks
Nig
