XZ1 dual sim 4G

[sebaa123]

Hello, so I want to buy it ,but , I have questions about 4G

1 ) The first sim is 4G right?

2) The second sim is 4G?

3) Bouth sims are active 4G?

Ex 

a) sim 1 data calls 4G, sim 2 data calls 4G

b) sim 1 data calls 4G, sim 2 data calls 3G.

4) Can bouth sims have data on?

5) If I receive a call the second sim or first sim is still active ?

Thanks

Hi @sebaa123;

You can not have 4G on both SIM cards, when you select 4G on one card the other one only have 3G (UMTS) or 2G (GSM) available.

You can have data activated on both SIM cards but you can only select one for data, the card you select to have 4G is the one used for data.

I don't know however how data calls work as I don't use them.

This is how the XZ Premium works but I guess is the same way with the XZ1 as they have exactly the same firmware.

Hi @sebaa123, thank you for showing interesting the Xperia XZ1 Dual SIM!

@NunoSEN2 pretty much covered it all, but I'll chip in with some extra information.

The device does not support 4G at the same time for both SIM cards, it works the same as @NunoSEN2 mentioned, one SIM card on 4G/LTE and the other SIM card will need to be on 3G/WCDMA or 2G/GSM.

You choose which SIM card you want to use the data traffic on, either SIM 1 or SIM 2.

Currently, Xperia devices support DSDS (Dual SIM Dual Standby), which does not allow you to handle two calls simultaneously on two different SIM cards. However, you can forward calls that come in on SIM card 1 to SIM card 2 when SIM card 1 is occupied, and vice versa. This function is called Dual SIM reachability.

Do note that Dual SIM reachability uses the Call forwarding feature. Check with your network operator to see if call forwarding is available in the networks that your SIM cards use. Call forwarding may not be available if you use SIM cards from two different countries/regions.

I hope that helps and let me know if there is any other questions!
