    • Some manufacturers are using Dual VOLTE to convey that both SIM slots support VoLTE. We can only confirm that View 10 supports VoLTE on both SIM card simultaneously after our review.

  2. Is there any features other than IMS+IMS?
    My doubt is IMS+IMS device we can two VoLTE sims(So that we can VoLTE Voice Call and Video call on both the sims with irrespective of data). Regarding data rate like LWG device only. Then what is the other use and other special features in IMS+IMS mobile

  3. In China Redmi Note 5 came with dual 4G dual Volte support but in India Redmi Note 5 Pro comes with single volte support. They both have the same chipset, so is it possible that xiaomi enables dual 4G dual Volte through an OTA update to Redmi Note 5 Pro in India?

  4. On the Amazon page of Honor View 10, to one question asking if it supports dual VolTe at the same time, a couple of answers say it does.

  5. Dual VoLTE can be enabled to existing phones with firmware or OTA update. Today my Nokia 6.1 got may update and the updated enabled Dual-VoLTE in my mobile. Nokia 8 also receiving the same update. Please list this mobiles in your article.
