How to Receive SMS Verification Codes While Traveling Abroad

Uber needs a code. Your email needs a code. The airline app needs a code. Every service you signed up for back home sends verification texts to a number that doesn't work where you are now.

If you've traveled internationally, you know this feeling. Your accounts don't care that you're abroad. They still want to verify you by SMS.

Why this keeps happening

Most services still rely on SMS for two-factor authentication. Your email provider, ride-sharing apps, social media accounts, crypto exchanges. They send a text message to your phone number, and you type in the code.

That works fine when you're home. It breaks when you're not.

Here's why:

Roaming is unreliable and expensive. Even with international roaming enabled, SMS delivery abroad is inconsistent. Some messages arrive hours late. Some never arrive at all. And you're paying for the privilege.

Local SIMs don't help. You can buy a Thai SIM in Bangkok, but your US email provider doesn't have that number. You need to receive codes on the number your accounts already know.

Dual SIM has limits. Carrying two active SIMs helps, but you're still dependent on your home carrier's international coverage. And you're still paying roaming fees.

App-based 2FA isn't always an option. Authenticator apps like Google Authenticator work great when they're available. But many services, especially older platforms, only support SMS verification. You don't get to choose.

The common workarounds (and why they fall short)

Most travelers cobble together solutions. None of them are great.

Asking someone back home to read codes. This works until it doesn't. Your friend is asleep, the code expires in 60 seconds, or you need a code at 3am their time. It also means sharing access to your messages with another person.

Google Voice. Free, but increasingly blocked by services. Many platforms reject Google Voice numbers because they're classified as VoIP. You won't know it's blocked until you're locked out.

eSIM from your home carrier. Some carriers offer international eSIM plans. They're expensive and the SMS delivery is hit-or-miss depending on where you are.

What actually works

The reliable solution is dedicated SMS forwarding. Instead of relying on your phone's cellular connection, you get a phone number that receives SMS and forwards the messages to wherever you are; Telegram, email, Slack, Discord.

The number lives in the cloud. It doesn't need a physical SIM, a phone, or a cellular signal. When someone sends an SMS to that number, you get it instantly on whatever device you have.

This is what Tether does.

Tether gives you a phone number in any of our 8 supported countries (US, Canada, UK, Australia, Netherlands, Sweden, Finland, and Estonia). U.S. numbers are assigned after checkout based on provider availability; other supported countries usually show available inventory before checkout. More coming soon. Messages forward to Telegram, email, or your platform of choice. The message arrives in seconds, not hours.

How to set it up

The process takes about five minutes.

1. Sign up and choose a country. Choose the country that matches your accounts. If your email is registered to a Canadian number, get a Canadian number. For U.S. numbers, you can request a preferred area code and Tether assigns the number after checkout based on availability.

2. Connect a destination. Choose where your messages go: Telegram, Email, Slack, or Discord. You can set up multiple destinations at once.

3. Update your accounts. Add your new Tether number as the phone number on file. Start with the critical ones: email, social media, anything that locks you out without SMS verification.

4. Travel freely. When a service sends a verification code, it arrives wherever you connected. No roaming, no SIM swaps, no asking friends for help.

A few things to know

Not every service works with virtual numbers. Some services specifically block VoIP and virtual numbers. We maintain a service compatibility page so you know what to expect. Many verification codes work fine, but check your critical services first.

Speed matters for verification codes. Codes typically expire in 60 to 120 seconds. Tether delivers messages in seconds, not minutes. That's the difference between getting in and getting locked out.

Multiple countries, one dashboard. If you need numbers in different countries for different accounts, higher-tier plans support multiple numbers. Manage everything from one place.

Who this is for

Tether was built for people who live internationally but have accounts that think they don't.

Digital nomads who move between countries but keep their home email, social media, and subscriptions.

Expats who settled abroad but still need access to services tied to their previous phone number.

Remote workers traveling for extended periods who can't afford to lose access to work accounts.

Frequent travelers who want verification codes to work the same way in Tokyo as they do in Toronto.

If you've ever been locked out of an account because you couldn't receive a text message, Tether fixes that.
