How to Get a Second Phone Number on iPhone (3 Real Options)
By 2Phon Team · · 6 min read
You can get a second phone number on iPhone with a carrier eSIM, Google Voice in the US, or a second-number app like 2Phon. Here's how each works and which one fits you.
Key takeaways
- There are three real ways to get a second phone number on iPhone: a carrier eSIM (Dual SIM), Google Voice (US only), or a second-number app.
- A carrier eSIM is the most complete line but needs a second phone plan and an iPhone XS, XR or later.
- Google Voice's no-charge personal plan offers US numbers only (as of October 2026).
- 2Phon gives you a real mobile number from dozens of countries for verification codes and calls, with no second carrier plan. It doesn't send texts.
To get a second phone number on iPhone, you can add a second carrier line as an eSIM, use Google Voice if you live in the US, or install a second-number app such as 2Phon. The right choice depends on whether you need to send texts, where you live, and whether you want a second phone plan at all.
This guide walks through all three options fairly, with what each costs, what it can and can't do, and how to set it up. If your goal is to keep your personal number out of sign-up forms and calls with strangers, 2Phon is an iPhone app that gives you a real second number for verification codes and calls.
Second phone number on iPhone: three options at a glance
All three put a second number on the same iPhone. They differ in cost model, countries, and whether you can send texts.
| Carrier eSIM (Dual SIM) | Google Voice | 2Phon app | |
|---|---|---|---|
| Separate number on the same iPhone | Yes | Yes | Yes |
| Make and take calls | Yes | Yes | Yes |
| Receive verification codes | Yes | Texts in the US only | Yes |
| Send texts | Yes | US only | No |
| Needs a second carrier plan | Yes | No | No |
| Where the number is from | The carrier's country | US only | Dozens of countries |
| Cost model | A second phone plan | No-charge personal plan (US) | Free trial, then a subscription |
Google Voice details come from Google's own plan comparison, which lists local numbers and SMS on the no-charge personal plan as "US only." Dual SIM details come from Apple Support.
Option 1: Add a second carrier line with eSIM (Dual SIM)
A carrier eSIM gives your iPhone a second full phone line from a mobile carrier, with its own number and its own plan. It's the most "real" second line you can have.
According to Apple, Dual SIM works on iPhone XS, iPhone XS Max, iPhone XR and later, and "both phone numbers can make and receive voice and FaceTime calls" and send and receive messages. There's one catch: "To use two carriers, your carrier must unlock your iPhone, or both plans must be from the same carrier" (Apple Support: Using Dual SIM with an eSIM).
How to set up a second line with eSIM
Get an eSIM plan from a carrier
Order a second line from your current carrier or another one. Check that your iPhone is unlocked if you use two carriers.
Open Settings, then Cellular
Tap Add eSIM or Set Up Cellular. Some regions label it Mobile instead of Cellular.
Activate the plan
Follow the carrier's activation: tap the setup notification, scan the carrier's QR code, or enter the details by hand (Apple Support: Set up eSIM).
Choose your default line
Pick which number iPhone uses by default for calls and messages to people who aren't in your contacts.
Good for: people who need full texting and calling on both numbers, and don't mind paying for a second plan.
Watch out for: a second monthly bill, an older iPhone that doesn't support Dual SIM, and a number tied to the carrier's country.
Option 2: Google Voice (US only)
Google Voice gives you a second number inside an app, and its personal plan is no-charge. The limit is geography: Google's plan comparison lists local numbers on the no-charge personal plan as "US only" (Google Voice Help, as of October 2026).
If you live in the US and want a no-cost second number for calls and texts, Google Voice is a reasonable first stop. If you live elsewhere, read our guide to Google Voice alternatives for people outside the US.
Option 3: A second-number app
A second-number app gives you an extra number that lives inside the app, on the iPhone you already have. No second SIM, no second carrier plan, and setup usually takes minutes.
Apps differ a lot, so check three things before you pick one:
- What kind of number you get. Many apps issue internet (VoIP) numbers, which some services refuse for verification. A real mobile number is accepted more widely. Our guide to virtual vs real phone numbers explains the difference.
- Which countries are available. Some apps only offer numbers from one or two countries.
- What it actually does. Some focus on texting, others on calls or verification codes. Pick the one that matches your job.

How to get a second number on iPhone with 2Phon
2Phon is a second-number app built for two jobs: receiving verification codes and making and taking real calls. Setting it up takes a few minutes.
Download 2Phon from the App Store
Get 2Phon on the App Store. It's an iPhone app. Start with a free trial; current plans are shown in the app.
Pick your number
Choose a number from the country you need. Numbers are real mobile numbers, not VoIP.
Use it to sign up
Enter your 2Phon number when an app asks for a phone number. The code arrives in 2Phon with a push notification. If the app offers "Call me instead," the automated call rings on your 2Phon number.
Make and take calls
Call people from your second number. They see your 2Phon number, not your personal one. Calls use minutes in the app.
What 2Phon doesn't do, so you know up front: it doesn't send text messages, and it's iPhone only. Texts sent to your 2Phon number show up in the app, and you reply with a call.
Which option should you choose?
Pick based on the one thing you can't do without.
- You need to send texts from the second number: get a carrier eSIM.
- You live in the US and want a no-charge number: try Google Voice.
- You live outside the US, or want a number from another country: use a second-number app such as 2Phon.
- You want a number for sign-ups and verification codes: use a real mobile number, not a free public one. Here's why free "receive SMS online" sites fail.
- You want a separate line for work calls: see how to get a separate work number on iPhone.
Tips for living with two numbers on one iPhone
A second number works best when each number has a clear job.
- Keep your personal number for family, friends and your bank.
- Use the second number for app sign-ups, marketplaces, deliveries and dating apps.
- Save contacts you reach on the second number with a note, so you know which line they have.
- If spam starts, you will know which number it came from.
Where 2Phon fits
2Phon gives you a real second phone number from dozens of countries on your iPhone. It receives verification codes from WhatsApp, Telegram, Google, Tinder and the other popular apps, and it makes and takes real calls, at home or abroad. It doesn't need a second carrier plan, and it's rated 4.8 on the App Store with 30,000+ ratings.
Keep your personal number to yourself. Download 2Phon on the App Store and use your new number the next time an app asks for one.
The bottom line
Every iPhone owner has a real path to a second number: a carrier eSIM if you need texting, Google Voice if you're in the US, or an app if you want a real number for codes and calls without a second plan.
