I converted several non-technical people to Signal, and a few were devastated to learn that getting a new phone meant that they lost their message history. They refuse to use it ever again.

The other sticking point is the phone number requirement. A (female) friend shared her “Signal” contact info with a professional acquaintance who doesn’t understand boundaries. After ignoring him on Signal, that led to unwanted SMS messages and even phone calls. For such a privacy-focused app, I don’t know why they are not more interested in protecting phone numbers.

I just had the experience with a friend whom I got to use Signal who was shocked that she lost her message history when switching phones. Our conversation about it was kind of awkward because I was thinking something like "mud puddle test" (https://blog.cryptographyengineering.com/2012/04/05/icloud-w...) and she was thinking something like "missing basic feature".

Agreed about true phone number requirement.

Sure supports connecting via @username only, and I’ve seen a few people switch to it for this reason alone (also the UI is a bit sleeker)

Does this hold for backup and restore to the new phone?

Yes.

There is no way to move messages from one iOS device to another (such as a new phone). My girlfriend recently got a new iPhone and wanted to transfer our Signal message history from her old iPhone onto the new one. She said it wasn't possible, and then I spent an hour or two reading about it figuring there must be some hacky awful way to accomplish it. I couldn't find one. This has been an open issue for years [0][1].

Android has an inconvenient backup flow (that involves randomly generated 30 digit PIN and manual transfer of file), but that's infinitely better than the total lack of options on iOS. I do wish Android (and iOS) had a method to download all message history to decrypted plaintext (or JSON) for use with other apps. If I own my data, decrypting it should be my choice.

I regret recommending to my girlfriend that we use Signal, and won't recommend Signal to more people after this.
