Will I lose all the converstaions and media on whatsapp if I do this?

Now I got a new iphone and I will move the simcard from the old iPhone to the new one, and I don't want to backup the whatsapp.
What I need to know is that if I put the simcard again on the old phone will I find my what's app conversations and media or it will be lost?

It will be lost, the SIM card doesn't store anything, all storage is on the flash memory of your iPhone which is why Whatsapp have a backup feature

Call your phone carrier before doing anything. A disaster may follow if you start off wrong.

No all the data of what's app will be deleted. You don't get any conversation detail on what's app. The Most Trusted and Popular Privacy Protector for Android, install Leo Privacy Guard in your smart phone, Very protective.
