How to Dual LTE mode or Enable dual SIM Card 4G

  • First go to the Settings
  • Tap on Network and Internet
  • Choose SIM Cards
  • On this Screen you will Find Toggle to enable Dual Cards 4G to enable 4G on both the cards


We also found that sometimes, when you insert Single/One SIM card in mobile phone 4G LTE/VOLTE works perfectly. But if you insert 2 SIM cards such as (one JIO sim and another SIM of 3G BSNL, Idea, Airtel, Vodafone) the 4G LTE Cellular internet data connectivity on the first sim stop working. This problem occurs due to the dual SIM card, so to fix this issue you need to enable DUAL LTE mode so that you can enjoy 4G / 3G on both the sim cards. Note: not all mobile phones support DUAL SIM 4G functionality.
