Text from your number on a computer, or another phone entirely
iMessage on a Mac, Google Messages on the web, and a couple of carrier apps can already do this. The steps below cover each one, and then the part nobody puts in the setup guide: what happens the day your actual phone is the problem.
On iPhone, turn on Text Message Forwarding first
Your Mac can't pull in ordinary green-bubble texts until your phone agrees to send them over. Go to Settings, then Apps, then Messages, then Text Message Forwarding, and turn on the Mac or iPad you want included. This step is easy to skip because iMessage between two iPhones already works without it, and people assume regular SMS will just follow along. It won't, not without this toggle.
Sign into Messages on the Mac with the same Apple Account
Open Messages on the Mac and sign in with the Apple Account you use on the phone. Then go to Messages, Settings, iMessage, and turn on Messages in iCloud so older threads show up too, not just new ones. If you want the person you're texting to see your phone number instead of your Apple Account email, pick your number under "Start new conversations from" in that same settings pane.
On Android, pair Google Messages for web instead
Same idea, different company. On the phone, open Messages, tap your account icon, and choose Device pairing. On a computer, go to messages.google.com/web and sign in with your Google Account and match the emoji that appears on both screens. Once paired, the phone vibrates and the computer starts showing your texts.
Know what both of those actually depend on
Apple states it plainly: your iPhone has to be turned on and connected to Wi-Fi or cellular for Text Message Forwarding to work. Google says the phone has to stay connected for Google Messages for web too. Neither one stores a separate copy anywhere. They're both relaying through the phone in real time, which means the computer only knows what the phone currently knows.
Check whether your carrier sells a real second line
A few carriers offer something that doesn't rely on the phone being switched on, because it runs as its own connection on the network instead of relaying through a handset. T-Mobile's DIGITS puts your number on a tablet or computer as its own connection, so check T-Mobile's site for which plans include it and what it costs. AT&T has a similar setup called NumberSync, which works on wearables, iPad, MacBook and select cars at no extra charge. Verizon shut its own Message+ app down in December 2024 and now tells customers to use Google Messages or Apple Messages instead, so Verizon users are back to the relay method above.
See where all of these run out of road
Every option above, including the carrier ones, assumes the line and the phone tied to it are still functioning and still yours. None of them help the day the phone is lost, stolen, or dead and you need your messages, contacts, and call history on some other device you're touching for the first time. That's a different situation than "my phone's upstairs," and it needs a different kind of setup, done in advance.
A copy of your line that doesn't live inside the phone.
MobileyMe keeps your contacts, messages, and call history in an encrypted cloud copy that isn't tied to one physical device. Sign in on whatever's around, a spare phone, a tablet, someone else's device, and you can call as yourself, with your real number showing on the other end, and text your contacts through the app. One honest limit: texts that other people send to your regular number still go to your SIM, so for full two-way texting on your own number from a computer, the Apple, Google and carrier options above are the ones to use. Signing out removes your MobileyMe data from that phone, so a device you borrowed keeps nothing of yours.
It only works if it's set up while your phone is still fine, not after. There's a free tier to start on, and going unlimited on calls and texts in the US and Canada runs $9.99 a month or $99.99 a year in the US; in Canada, see the app for your price.

Can I text from my number without my phone at all, using the free built-in tools?
No. Apple's Text Message Forwarding and Google Messages for web both require the original phone to be turned on and connected to Wi-Fi or cellular data. Neither one keeps a running copy anywhere else, so if the phone is off, dead, lost, or stolen, the forwarding stops the moment the phone does.
Does Google Messages for web work if my phone is off or out of signal?
No. Google is direct about this: messages reach your computer through a live connection from your phone, and that connection needs the phone online with a Wi-Fi or data signal. Only one computer can be actively paired at a time, too.
I'm not on T-Mobile. Is there any multi-device option that doesn't depend on my phone?
Not usually. Verizon shut down its own Message+ app in December 2024 and now just points customers to Google Messages or Apple Messages, both of which still relay through the phone. T-Mobile's DIGITS is a separate feature that isn't tied to a single handset, so check T-Mobile's site for which plans include it and what it costs.
