LG G5 (LS992) Will It Move Over From Sprint To T-Mobile As Part And Work After 3G Retirement
When I put my IMEI number for my LG G5 (LS992) in on the T-Mobile Bring Your Own Device page, it says it is unsupported. However, the LG G5 appears to have everything that would be needed to make th...
Thank you so much @syaoran .
It is true that I have seen some phones list VoLTE for only AT&T and T-Mobile (such as this phone ), it seemed to have more to do with them only supporting the GSM/UMTS network, with no support for CDMA networks.
As far as standards are concerned, VoLTE (not HD-Voice, or Extended Range LTE over band 13) has a standard (which although not all options are required, should work between carriers that implement it and allow it):
Even Sprint acknowledges that VoLTE on the their network should transfer over to T-Mobile (for capable devices, which in the “Which Devices Support VoLTE” section, it lists LG G Series):
However, I do notice in the last link above, in the "Which Devices Support VoLTE" that it does say LG G7 and newer. The G5 LS992 has a "Voice clarity" option which some suggested was how to turn on VoLTE (although I found another forum that stated they had an actual VoLTE setting - which my phone does not have). I went ahead and looked up the original specs for the LG G5, and I found that the LS992, and the factory unlocked RS988: versions of the G5 do not specifically list VoLTE in the specifications section, although the H831 version does list it in it's specification section. Interestingly enough though the H830 version of the G5, T-Mobile’s version, does not list VoLTE (even though their is a T-Mobile support document that lists it as having VoLTE).
So, after your post got me to digging a little further, it seems like the Sprint LG G5 LS992 out of the box may not actually have VoLTE like I thought it did (at least that helps sooth my heart in not feeling frustrated in having to buy another phone when I thought my phone had the appropriate capabilities out of the box). Although, if you have a link that shows that Sprint's VoLTE and T-Mobile's VoLTE are not compatible, that would be helpful too.
Thank you so much for taking the time to answer - I really appreciate it.
