Why is this app used by everyone? What's cool about this app?
- You have to do nothing after the download except this sms-verification
- No account creation
- No new password (or reuse another one <- li="" nooo="">
- No need for searching addresses
- You do not have to take care about your contact list
- Just start messaging ->
Not at all: If you want to add whatsapp on a second device with no sim card (e.g. your tablet), you can find several instructions but: after adding whatsapp to this device, whatsapp on your phone does no longer work...
Your WhatsApp account can only be verified with one number, on one device.Finally i would say: The biggest advantage is also the biggest disadvantage. Using the phonenumber as account id makes everything easy but prevents the usage of more than one device....
If you attempt to frequently switch your WhatsApp account between different devices, at a certain point, you may be blocked from re-verifying your account. So please do not repeatedly switch between different devices.
