Technically, yes, you can use GBWhatsApp (GBWA) and the official WhatsApp on the same device — but there are important things you should know: • Different phone numbers: You need to use two different phone numbers (SIMs) because WhatsApp doesn't allow two accounts with the same number. • Separate apps: GBWA is a modded (unofficial) version of WhatsApp. It installs separately, so you can have both apps (GBWA + official WhatsApp) running on the same phone. • Security risks: GBWA isn’t officially supported by WhatsApp, and it may expose your data or lead to a ban from WhatsApp. • Installation: Since GBWA isn’t on the Play Store, you’ll have to download the APK manually and allow Unknown Sources in your settings to install it. Quick Tip:Some users even use Dual Apps/App Cloning features (available on brands like Samsung, Xiaomi, etc.) to manage multiple WhatsApp accounts more safely.
