That's how it worked on my g3
I don't think so. How it worked in G3 was that u could choose either sim 1 or sim 2 as your preferred sim and can activate 4g on the sim of your choice. But if you chose sim 1 as your preferred sim and chose 4G/LTE, sim 2 would automatically be switched to 2g and vice versa.
In moto G4 you don't get the option to use 4G on sim 2 at all. If you choose sim 2 as your preferred sim for data, you will only get 3G speeds. So if you want to use a 4G connection, you will have to place the 4G sim in sim 1 slot.

I just got my moto g4 and it is dual 4g like it says on Motorola website
I don't know where in motorola website you got your info but you are incorrect. As you can see in the screenshots, there is no option to choose 4g for the 2nd sim.

I am getting 4G option on SIM slot 2. But what i am seeing that i am not getting any data network on 4G in this slot. 3G works like a charm on this slot. Let me use Slot 1 and see if i get 4G data.

That is really strange. I am pretty sure that the 2nd sim does not support 4g as i saw this info on various sites n reviews before buying the phone.
As for u not getting 4g on the 1st sim, that has to be a network issues imo coz 4g is working with no probs for me on airtel in two different cities too.

My Moto G4 Plus UK dual sim can do 4G on Sim1 and Sim2 but NOT at the same time, if Sim1 is 4G then Sim2 is 3G (or 2G), if you make Sim2 4G then Sim1 is 3G (or 2G)
Most importantly is that when one sim is running as voice+data 3G or 4G, the other sim can still connect at 3G which is not common on most dual sim phones.

Yes i also discovered these aspects recently.. Tbh it's a good implementation of dual sim management...

It is dependent on which SIM you set as your preferred SIM for mobile data. Which ever SIM is selected 1 or 2, that can do 4G and the other SIM can do 3G/2G only.

So I keep one on 4G and the other on 2G save battery and also have a more stable connection (well that varies from provider/region).

The Qualcomm Snapdragon processor 617 (and the close related 615) cannot do simultaneous 4G/LTE on both SIM's, only one at a time.

How did you set one on 4g and other on 2g.

My first slot is on 4G.
My second slot is not showing option to select 2G, it is dehighlighted and set to 3G.

Step 1 : Set the preferred sim for data, this is the sim that can do 4G.

Step 2 : Update the network type for the other sim.

As you can see from my screenshots, it's the SIM in slot 2 that is doing 4G and the first slot is set to 2G. If you select the preferred sim for mobile data to be the first sim, then that will be the one with 4G and the second slot will be restricted to 3G/2G.

Hope that was clear?
