Hello! I bought yesterday MEIZU m3s Y685H and readed before some presentations and specs, they say that m3s support ALL Russian LTE Bands and Russian VoLTE, but:

- In setting i cannot see VoLTE toggle option
- In engineering menu, i cannot activate LTE Band 20 (thats band used in Russia and EU countries) and proprietary LTE Band 31 (Used in Russia by SkyLink LTE 450 MHz)


About VoLTE.... Now its launched on Beeline MCC 250 MNC 099 and MegaFon MCC 250 MNC 002

For Beeline, VoLTE is fully compatible with 3GPP specification, uses method AKA for authentication, IMS APN is ims.beeline.ru with IPv4/IPv6 protocol. Username and Password of IMS APN is empty.

For MegaFon its used special SIM (with ISIM applications), all of IMS parameters stored on the sim.



Will Flyme add support VoLTE / VoWiFi and additional LTE Bands for Russian Carriers on MEIZU M3S ?
