Edit: Oh yeah, DON'T USE SIGNAL. Use Matrix instead, offers the benefits of signal without the drawbacks of lack of sync and phone number requirements and is decentralized. The fact that everyone is going gaga for signal as "the BEST messaging app" should be a big red flag in and of itself, because hype trains like this aren't organic, just saying.
might I suggest using Matrix instead? End to end encrypted and fully open source (client and server), plus message history gets synced to new devices (assuming both your old and new clients support it, which nearly all do), and as a bonus it doesn't store data on a centralized server.
Oh, and it supports sticker packs and custom emoji.
