You may or may not have stumbled across my comment on a post from a few days ago, mentioning how I fake banned my account on WhatsApp (attached below) when in reality I just deleted it.
Well, it worked like a charm. I got my close friends and my significant other to switch to Signal, I told them we have no choice since I got banned and won’t get my account back, and told them that Signal was developed by the same people who once worked at WhatsApp before Facebook bought them. And it worked.
Just for your information, I am a zoomer in the US, the group which is probably the hardest to do this with, yet I did it (although granted we all used Whatsapp before which is also not very common in the US especially among zoomers who love Snapchat and Instagram DMs)
Usually I have success in mixed iPhone/Android groups where I mention that if we all used Signal the group chats won’t suck.
I tend to be the photographer so when I take a good pic and someone asks for it I say “are you Signal? I want to send you the photo without it being compressed”
