You can try recommending quicksy. It's been launched fairly recent and is an effort from the conversations developer to reach a similar userfriendliness as other phonenumber-based messengers have, while still being open to other users who decided to go with the regular accounts (e.g. you). You can even bind your phonenumber to your jabber account, so you show up as a concact without them having to add your jabber id to their phonebook.
