Swap 3G between SIM 1 and SIM 2

vicdj

Hello,

Sorry for my bad english!

I am new user of UMI Emax and have question! I use two sim cards. When i try to change settings on preffered networks i can do this only on sim card in slot 1. I can't change 3d/4g settings for sim card in slot 2. Is possible set sim card in slot 2 with 3g/4g setting without change sim cards from slot 2 to slot 1???

I don't find this option, but somewhere read that this CPU can swap 3g/4g settings from menu.

Thank you very much bencebacsi for quick reply!

Strange, In menu "Mobile networks" i don't have option 4G/3G service.  I have "Preferred network type" - in this menu i can choose 4g/3g but only for sim card in slot 1. Sim card in slot 2 don't show in this menu. When i touch "Preferred network type" i see only sim card in slot 1. I am with original stock firmware and never change firmware. Is problem is only for my phone or is normal to see only card in slot 1 on UMI Emax? I have other china phone, some very cheap and never have this problem.

Thanks for help.

Yes, both SIM cards are active in SIM management, i make call and receive calls with both without problem. In every other menu i see both sim card, only in  "Preferred network type" when i change 3g/4g/2g mode i see only sim card in slot 1. I try swap physically sim cards - again in "Preferred network type" i see only card on slot 1, before i don't see in menu this card because was in slot 2. Bencebacsi, do you have two sim cards in UMI Emax and can swap from menu. If yes, What frimware use?
