How to Get a US Phone Number: Your Guide to Phone Number Apps

Want to secure a US phone number before your trip? Are there apps that let you get one from your home country? The short answer is: yes—you can often get a US phone number using a phone number app, even if you're not in the US yet. However, there's an important distinction to understand: receiving SMS messages and passing SMS verification are not the same thing. VoIP-based phone numbers may be rejected by some verification services, so it's best to decide your primary use first—communication or verification—before selecting an app (as of September 2026).

This guide covers how to get a US phone number from outside the US and explains the common features of popular phone number apps. We'll create a table showing what each method can and can't do, and discuss why an internet connection is essential for these apps to work. If you'd like to explore data plans for the US first, check out our US eSIM guide.

How Phone Number Apps (VoIP) Work

Phone number apps use internet-based calling (VoIP) to give you a phone number, rather than relying on a mobile carrier contract. If you're familiar with VoIP numbers, this works the same way—using Wi-Fi or mobile data, you can make and receive calls even when you're abroad.

The advantage is that you can have a phone number within an app without changing your SIM card. However, both calls and SMS require an active internet connection, so they won't work without a network connection. This is different from a traditional carrier number, which works through cellular infrastructure. Traditional carrier numbers are more reliable for calls and SMS verification, but they require a contract and may involve roaming fees or restrictions when used abroad. Phone number apps are convenient and let you hold multiple numbers at low cost, but some services may reject them for SMS verification.

How to Get a US Phone Number from Outside the US

Bottom line: If you want to get a US number before your trip and handle it all through an app, a VoIP phone number app is usually the easiest option. However, if you need a number for critical identity verification, consider also planning to get a local US number after you arrive. There are three main approaches, each with different trade-offs in convenience, cost, and verification success:

• Phone number app (VoIP): You get a US number through the app and make calls and send SMS over the internet. It's easy to sign up from outside the US.
• Local carrier number (prepaid SIM, eSIM, etc.): You get a number from a local carrier after arriving in the US. Generally more reliable for verification, but requires in-country setup and ongoing commitment.
• Help from someone local: Limited to cases where you have local friends or family who can assist—not a practical general solution.

Method	Get from Outside US	Ease of Use	Verification Success	Best For
Phone number app (VoIP)	✓ (Sign up in the app)	● Very easy—app-based	△ May not work for all services	Communication, temporary use
Local carrier number	✗ (Typically after arrival)	△ Requires setup	○ Generally accepted	Long-term stays, critical verification
Local assistance	—	—	—	Not a general solution

The "verification success" column reflects general trends only. Each service uses different rules, and they change over time, so no method is guaranteed to work everywhere.

【Critical】SMS Reception and SMS Verification Are Different

Bottom line: A US number from a phone number app can work for casual messages with friends, but may fail verification from banks, brokers, government services, Google, Apple ID, WhatsApp, and other platforms that check if your number is from a carrier or VoIP service. This is where many people get stuck.

These services can identify whether your number is from a traditional carrier or a VoIP source. They often block VoIP numbers from verification. The rules aren't public, and a number that worked before may stop working later. Don't assume an app-based number will pass every verification—it won't. Understanding this will help you plan better and avoid surprises after you arrive.

How to Handle Verification Failures

For important accounts (banks, brokers, government services, payment apps), the realistic approach is to plan ahead, assuming app-based numbers may not work. Here are three practical steps to take before you leave:

• Keep your home-country number active: If you use services that send SMS verification to your current number, keep it working while abroad. See how to receive SMS from your home country while abroad.
• Set up services in the US later, if needed: For services that require a US number, consider registering or verifying them after you arrive with a local carrier number.
• Switch to alternative authentication: Many services let you use authentication apps or email verification instead of SMS. Switch before you leave to reduce dependency on phone numbers.

Popular Phone Number Apps: General Features

Bottom line: Each app has strengths—some excel at temporary use, others at privacy or free options, and some have more strict conditions. Below are widely-known characteristics. Supported countries, pricing, and SMS availability change, so always check the latest official information and app store details before signing up (general trends as of September 2026).

Hushed

Often described as best for temporary or short-term numbers. It supports multiple numbers and prepaid options, making it a good fit for travelers and short-term work trips—situations where you need a number for a specific period.

MySudo

Marketed toward privacy-conscious users who want to keep numbers separate by use. It bundles number, call, and message management, making it appealing to people who want to separate work and personal communication.

TextNow

Known for offering a free tier, it's often mentioned as an easy, low-cost way to get started for personal communication. However, free plan limits and number retention conditions change, so check the latest terms before signing up.

Google Voice

A popular name, but it has conditions: you often need an existing US phone number to set it up, which can be a blocker if you're trying to get your first US number from abroad. Always check the latest signup requirements on the official website.

Apps Vary by Country

The numbers you want affect which apps are available. If you're interested in multiple countries, here's a quick overview of common options. Check app stores and official sites for current pricing and features:

Phone Number Needed	Popular Apps	Best Use Cases
Canada	Fongo, etc.	Short-term stays, connecting with local friends or roommates
US or UK	Hushed, MySudo, TextNow, etc.	Temporary local numbers, keeping personal and work communication separate

What to Look for When Comparing Apps

• Pricing model: Monthly subscription or pay-as-you-go? For short trips, calculate total cost; for longer stays, compare monthly or annual rates.
• Number retention rules: Some apps delete numbers if unused for a certain period. Check the conditions so you don't lose your number while away.
• SMS support: Some plans offer calling only, with SMS limited or unsupported. Verify it matches your needs before signing up.
• Signup from your home country: Some apps have regional restrictions or require specific payment methods. Verify you can sign up from where you are.
• Cancellation process: Understand how to turn off auto-renewal. Knowing this beforehand prevents accidental charges after you return home.

How to Choose Based on Your Needs

Bottom line: For staying in touch, a low-cost app often works fine. For critical verification, also plan to get a local US number or use a backup method.

• Business or ongoing use: Prioritize stability and ease of management. If you need separate numbers for different purposes, look for apps that support multiple numbers. For important verification, don't rely only on an app number—also plan to get a local number or use alternative verification methods.
• Personal communication with friends: If calls and messages are your main need, free or low-cost apps are usually sufficient.
• Short-term or temporary use: For vacations or brief work trips, disposable or short-term plans make sense. But check cancellation terms before signing up.

Phone Number Apps Are Right for You If:

• You want to connect with new friends, hosts, or local contacts before arriving in the US
• You need a US number for restaurant reservations, delivery orders, or other casual situations
• You're visiting for a short time and don't want to commit to a local carrier contract
• You rely mainly on messaging apps like WhatsApp for staying in touch

Phone Number Apps May Not Be Enough If:

• You need to open a bank account or navigate government services that require verified phone numbers (consider getting a local carrier number instead)
• You need to receive SMS verification for your home-country services while abroad (keep your home-country number active instead)
• You need to receive calls in areas without internet access (app numbers require an active connection)
• You need to reliably receive automated messages from local businesses or services (a local carrier number is more reliable)

What Phone Number Apps Can and Can't Do

Feature	Phone Number App (VoIP)	Notes
Make and receive calls in the US	○ (usually works)	Costs and features vary by app. Requires internet connection on both ends or a regular call to your number. Data connection required.
Send and receive SMS with friends	○ (often works)	Depends on the recipient's ability to receive from your number. Success varies by country and app.
SMS verification from banks and brokers	△–✗ (may fail)	These services often block VoIP numbers.
SMS verification for Google, Apple ID, WhatsApp	△–✗ (may fail)	Not guaranteed to work. Test beforehand if possible.
Replace your home-country number	✗	Home-country services typically expect your home-country number for verification.
Get a number from outside the US	○ (sign up via app)	Some apps like Google Voice have specific requirements; check the official site.
Use internet calling apps	○ (with data connection)	Phone number apps themselves require internet; internet apps rely on data.
Use WhatsApp, Telegram, or Instagram calls	○ (with data connection)	These apps use internet, not your phone number.
Browse maps, social media, or make reservations	✗ (not on its own)	You need a separate data connection (such as an eSIM) for internet access.

The key takeaway: Phone numbers from these apps work for casual communication but may fail for important verification. For details about data-only eSIMs and how they relate to phone numbers, see Can you use phone numbers, SMS, and calls with an eSIM?

Steps from Signup to Using Your Number

Bottom line: Most apps follow an "Install → Create account → Choose location → Pick a plan → Verify" flow and let you finish from your home country. Details vary by app, so here's the general outline:

1. Install the app and create an account: Sign up with email. Some apps may ask for an existing phone number during signup.
2. Choose your area (state or area code): Pick a location near where you'll be staying—it looks more natural when you share the number.
3. Select a plan (monthly, pay-as-you-go, etc.) and pay: For short trips, monthly plans make sense; for longer use, compare the total cost.
4. Test calls and SMS: Call a friend or your other number and send an SMS to confirm everything works before you leave.
5. Set up your data connection for your trip: The phone number app needs internet to work; prepare your data plan for when you arrive (explained next).

Note: SMS messages to your app-based number arrive in the app itself, not in your phone's standard messaging app. Make sure notifications are enabled so you don't miss incoming messages.

Phone Number Apps and Data Connections (eSIMs)

Bottom line: Phone number apps need an internet connection to work. Calls and SMS through these apps use data, so once you arrive, you must have a reliable connection. Hotel and café Wi-Fi alone won't cut it—you'll lose connectivity during transit and on arrival, when you might need to message people or order transportation.

Here's the important part: Bloomy eSIMs provide data-only service—meaning no phone number, SMS, or voice calling from Bloomy itself. That said, internet apps like WhatsApp, Telegram, Messenger, and FaceTime work normally, and the phone number apps described in this article work too, as long as you have Bloomy's data connection. If you need actual phone numbers, SMS, or voice calling, you can pair a phone number app with your eSIM, or explore a local carrier plan.

Here's a practical setup:

1. Internet access: Use your eSIM plan for maps, social media, bookings, and app calls.
2. When you need a number: Use a phone number app alongside your eSIM. Both work through your data connection.
3. Critical SMS verification: Plan for potential failures—keep your home-country number active, or use alternative authentication (apps, email).

Bloomy setup is simple: tap the link in your purchase email, follow the on-screen steps, and activate when you arrive. For detailed steps, see our setup guide; to check device compatibility beforehand, see compatible devices. Connection speed depends on local networks, your device, and signal strength in your area—it may vary by time and location.

Important Points to Check Before You Get a Number

• Decide your purpose first: Will you use it mainly for staying in touch or for verification? If verification, plan for potential failure and have backup methods.
• Always check current information: Supported countries, pricing, and SMS support change. Check the official website and app store listing before signing up.
• Country and region support: Confirm the app supports the number you want, and that you can download it from your home country's app store.
• Cancellation and retention terms: Some apps delete unused numbers after a period. Understand the terms, especially if you plan to keep the number after you return home or stop traveling. Know how to turn off auto-renewal to avoid surprise charges.
• Plan for your home-country number: A US phone number doesn't replace your home-country number for services back home. Decide whether to keep it active, pause it, or close it based on which services need SMS verification.
• Prepare your data connection: Don't forget the internet you'll need to run the phone number app. Check our guide to phone number apps for international stays for more context. If you run into connection issues, see our troubleshooting guide.

Summary

You can often get a US phone number using an app before your trip. The key is understanding that casual messaging works, but important verification often doesn't. Choose based on your actual needs, and always have a backup plan for critical verification—keeping your home-country number, setting up a local number after arrival, or switching to other verification methods like apps or email.

Also, remember that phone number apps require an active internet connection. Prepare your data setup before you leave. Check our US eSIM guide and comparison page to find a plan that fits your destination, data budget, and travel dates.

Phone number apps, service verification rules, and eSIM plans change regularly. Always check the official information from each app, service, and provider before purchasing or signing up.
