That depends on where you port it. If you port to a second prepaid wireless plan (Mint Mobile, US Mobile, Tello, Tello, Visible second line), you'll need a second physical SIM or a second eSIM profile on your phone. Modern iPhones (XS+) and Pixels support multiple active eSIM profiles, so you can have your primary and second number on one device simultaneously. If you port to Google Voice or a VoIP provider, you don't need a second SIM — calls come through their app.

Yes, that's the typical setup. With dual-SIM/eSIM, your iPhone or Pixel shows both numbers in the dialer and call log; calls to either ring the same device with different ringtones if you want. With Google Voice + native line, calls come through the GV app while your native number rings through the standard dialer. Either model works for most second-line use cases.

Yes if you port the second number to a real wireless carrier (AT&T, Verizon, T-Mobile, Mint Mobile, US Mobile, Cricket, Google Fi, Visible). Banks deliver SMS 2FA codes normally to wireless numbers. Some banks block SMS delivery to numbers flagged as pure-VoIP (Google Voice, RingCentral, Twilio), so if banking 2FA matters, choose a wireless carrier as the destination.

Technically you could, but the economics don't favor it. Burner-app numbers cost a few dollars and are designed for short-term use. Buying outright at $200–$250 only makes sense if you plan to keep the number for years. For genuine short-term burner use, apps like Burner, Hushed, or a 1-month prepaid Mint Mobile line make more sense. Digit Exclusive is for permanent ownership.

Major carriers (AT&T, Verizon, T-Mobile) let you add a second line for $20-40/month per line — but the number they assign is random from their pool, and you continue paying monthly for the line and the number combined. Digit Exclusive lets you pick the exact second number you want, pay once for the number, then add it as a second line on your existing carrier (most allow port-in of a number you bring) where you continue paying your carrier's normal monthly fee for service. You get the number you want, permanently, without paying extra for a "vanity" upgrade from the carrier.

Yes. Once you port the new number to a destination carrier, it's a fully-functional standard US line on that carrier. You can cancel your old primary number (the carrier disconnects that line) and the new number becomes your main number. Many people use this exact path to "upgrade" to a memorable number while keeping ownership permanently — they buy a memorable number, port it to a new carrier line, then cancel their old number.

Transfer kit arrives by email within 1-5 business days. After you submit to your destination carrier (and add the second line/eSIM/SIM), port-in takes 24-48h wireless or 3-5 business days wireline. Total: typically 2-10 business days end to end. Faster paths exist for some prepaid carriers (US Mobile, Mint Mobile) that can complete port-in within a few hours of submission.
