firstly you must format cpu,s

and write imei numbers,if not solved you must reflash your phone,
its the way if there is no hardware problem

if u check in software then in hardware check dual sim ic (some mobiles have some haven,t)

if haven,t then check lines from power ic to sim connector .

if lines r ok then it is missing from cpu then rehot or reboll cpu.
