Here you can see Phone1 and Phone2, in that select phone2, because most of the Chinese clone phone the 1st Sim which is a 3G will work perfectly. Only the problem happens when we insert the second sim. If you check you can see the IMEI of 1st sim will start with 35xxxxx and the 2nd will start with 88xxxxxxxx. That is why the second sim is not able to register to the network, because its not in international formatted IMEI. So usually we need to change the IMEI of phone 2.
Select the phone 2
