![]() Telegram is popular, although it doesn't use end-to-end encryption by default. Unfortunately, iMessage and RCS aren't compatible with each other, so iPhones and Android phones will have to communicate over SMS-or switch to different chat apps that aren't built-in. Hopefully, Android users will one day have secure end-to-end encrypted messages built into their devices after improvements are made to RCS. If you have an iPhone, communicating with iMessage is much more private and secure than using plain old SMS. We used Signal as the example here as the contrast is so stark- Signal is the most widely recommended private chat app, with always-on end-to-end encryption. Even if the scammer could somehow guess your PIN and access your Signal account, your Signal messages are stored on your phone and wouldn't be synced to any new devices that gain access to your account. ![]() You can protect your Signal account with a PIN, so a scammer can't just access your Signal account. A port-out scam that captures your phone number wouldn't grant access to your Signal account.All they can see is encrypted traffic being sent back and forth to Signal's servers. Authorities can't snoop on the content of Signal messages-not without getting their hands on a phone that contains them. Stingrays can't see your conversations.(In contrast, SS7 has been repeatedly compromised.) They would have to compromise the Signal encryption protocol, which security experts consider excellent. Signal messages can't realistically be hijacked by hackers.If forced by subpoena, Signal can reveal almost nothing about your usage of the service. Not even Signal can see the contents of your messages or who you're contacting-that remains a secret. Your cellular carrier can't see the contents of your messages.Your conversation data is only stored on your device and the device of the person you're talking to-that's it. Signal doesn't even know who you're talking to. Signal doesn't have the contents of your communications. These records could be subject to subpoena in legal proceedings-for example, text message records are a common form of evidence in divorce cases.Ĭompare this to an end-to-end encrypted chat app like Signal. Messages are often only retained for several days, but they store metadata (which number sent a message to which number, and at what time) for even longer. Those messages are stored on your cellular provider's systems-so, instead of a tech company like Facebook seeing your messages, your cellular provider can see your messages.Ĭellular carriers store the contents of those messages for various amounts of time. Your cellular provider can see the contents of messages you send and receive. With SMS, messages you send are not end-to-end encrypted. Your Cellular Carrier Can See Your SMS Messages
