How i take call both sim at the same time #samsung #A71

but how you can receive 2 calls in same phone at once🙄🙄🙄😇😇
you can enable waiting.. or forwarding to other number in other handset

It will not take.
Because limited handsets have dual sim and dual active. Because it needs 2 transceiver extra space and more battery expense.

Android phone basically have two different dual SIM systems, AFAIK:

DSFA (Dual Sim Full Active): both SIMs can receive calls simultaneously, and you can switch between one call and the other

DSDS (Dual Sim Dual Standby): when one SIM is receiving a call, the other one is in standby. It will receive nor calls, nor SMS. It is like the second SIM is put in a phone turned off. As soon as the call ends, both will return to active state.


Like DSFA and DSDS, also network coverage for different SIMs is all on the manufacturer's choice: I once had a cheap Dual SIM phone (not even a smartphone) which had a UMTS first slot and GSM second slot, but most smartphones today (all high-end ones for sure) offer LTE on both.

Android also allows you to select a favorite SIM for various action: you can always choose which number you want to call or send from, but if you have a plan good for messages and one made for voice calls, you can tell Android to send SMS from the first SIM and calls from the second, unless specified otherwise. So, you don't risk spending more than you should when forgetting to tell which SIM you want to use for a call, or to switch SIM.


Hope this helps for your queries. Thank you. 😊

No, it didn't solve his query. He wants to know how to take calls on both sim not what is dsda and dsds.

[Souravonline98]

what is the function of this option

[iamiceparticle]

There is setting. Go to connection, manage sim card, more sim card setting.
I suppose it will allow you to take calls on both sim.
But actually it forwards the call of second sim to the sim on which you are on call currently.

Samsung introduced a new version of Dual SIM technology called Smart Dual SIM which means the device with this feature will have the following quality while the user connects two GSM SIM cards simultaneously :

● There is an option of making one of the cards primary which would act like a Master SIM card, and the other one as  secondary.

 

● When the user is busy using SIM1, SIM2 will not work until Call Divert is turned on by the Mobile Network operator.

 

● If the user is using SIM2 as modem for connecting Internet then SIM1 can be used to take calls and that is  why the user should select SIM1 carefully as it acts as the primary number.

This is what I got from Samsung website. Which confirms my above coment.
