Care to back your statement by posting a small pic of any of these phones displaying 4G on both network signals at the same time taken from another mobile phone camera?You are the first person I know both in real & online life to make such a claim because as far as I know no phone can receive 4G signals on both sims at the same time.
@billubakra be more specific in your queries like this.Why do you need 4g in both sims at the same time?If you are thinking about using Reliance Jio 4g only sim with another 4g sim to simultaneously use 4g in both then forget about it as it is not possible.In fact if you see technical specifications of almost any dual sim mobile it says "dual-standby" which means you can not simultaneously use both sims while making/receiving calls or using data(any incoming/outgoing call will disable the other sim temporarily for the duration of call so you can not talk using one sim while simultaneously downloading from the internet using another sim).
