@Mer__edith , many countries around the world don't receive an activation code from #Signal. In Russia, for example, almost all instant messengers are blocked, except for Signal, Jabber and DeltaChat, and Signal could well have become #1 in Russia if not for this problem with the SMS codes. There is also the problem with SMS activation codes in Nigeria, Pakistan, Ecuador, Myanmar, etc. (Please see at https://github.com/signalapp/Signal-Android/issues/)
