I have been using https://silent.link happily for a year now, though I know some people who've had issues with it. An alternative is https://crypton.sh, though I have not used it myself. Also it seems like you can't just get data service without a phone number, which you can do with silent.link. nostr:nevent1qvzqqqqqqypzpq35r7yzkm4te5460u00jz4djcw0qa90zku7739qn7wj4ralhe4zqqsrmh4r3uzz6xssw4u3urke7va78r7sh8tjl7jkreedgksqmntuscqdmrd8w
