So, I want to restore my phone to factory settings, which means whatsapp will be deleted. I use my old number on whatsapp, and I don't have the SIM Card. My question is if I downloaded WhatsApp again and tried to sign in with my old number, can I do that ??
((e.g.)) old no. 0598514173 - whatsapp new no. 055112233 - NO whatsapp can I use the old one once again ??
