Dual sim

[Christell]

I have been having issues with Samsung Galaxy S21 Ultra.  I am using the dual sim for two sim cards,  however I cannot download whatsapp.  This is absolutely frustrating.

you can't download Whatsapp at all or you can't download for your second number

I can't download on my second number

Hey there

It won't work, whatsapp is designed that way, what you should do is.

Open settings and type, Dual messager, and enable for whatsapp.

That will do the trick

have you tried this advance setting and active your second Whatsapp

You don't have to download another whatsapp for the second number, Simply go to Settings >Advanced features >Dual messenger. From there you may add you second WhatsApp for your other number
