Some Important FAQ About WhatsApp
What is WhatsApp?
WhatsApp is an instant messaging and VoIP service owned by Meta, launched in 2009. It allows users to send texts, voice and video messages, make calls, and share media like photos, documents, and locations.
How do I add contacts?
You need someone’s phone number saved in your device’s contacts. WhatsApp will recognize and display their account if active.
Can you use WhatsApp without a phone number or SIM?
Technically, a phone number is required to sign up, but it doesn’t have to be your SIM number—landlines or virtual numbers (e.g., via TextNow) can work.
How do I format messages (bold, italics, etc.)?
You can format text using symbols: bold, italics, ~strikethrough~, monospace.
Can I unsend or edit messages?
Yes, messages can be deleted for everyone within roughly one hour after sending. You can also edit messages—but only within a 15-minute window; edited messages are marked with an “Edited” label.
How do I back up chats?
You can back up chats to Google Drive (Android) or iCloud (iOS). Go to Settings → Chats → Chat Backup to manage backups.
What do the check marks mean?
One gray tick: message sent; two gray ticks: delivered; two blue ticks: read. Tap and hold a message → Info to see exact timestamps.
Can I disable automatic media downloads?
Yes—go to Settings → Data and Storage Usage → Media Auto-Download and customize what’s downloaded on Wi‑Fi, mobile data, or roaming.
Can I control who adds me to groups?
In Privacy Settings → Groups, you can choose who can add you: Everyone, My Contacts, or My Contacts Except.
Can I see who viewed my profile or status?
No, WhatsApp doesn’t provide visibility into who views your profile. And while you can see who viewed your status updates, this only works within a timeframe before the status expires.
How do I delete my account?

Can I use WhatsApp on multiple devices or a tablet?
