How to keep your US phone number when moving abroad

Your US phone number is tied to almost everything: banking 2FA, IRS notices, brokerage logins, Venmo, your doctor, and the family group chat. Losing it the day you land abroad creates weeks of friction. This guide covers the realistic options Americans use to keep a US number after moving — what each one costs, what breaks, and what fits which situation.

Why you probably need to keep your US number

Most US banks, brokerages, and credit cards only send SMS-based 2FA codes to US numbers. Some refuse non-US numbers entirely (Chase, Fidelity, Schwab are common offenders). Voice-only callbacks to foreign numbers often fail too. If you drop your US number, expect to be locked out of at least one important account within the first month — usually the one you need most urgently. Keeping the number active for $0–$5/month is almost always cheaper than the recovery process.

Option 1: Google Voice (free, the default pick)

Port your existing US mobile number to Google Voice for a one-time $20 fee. Once ported, the number is free forever, receives SMS and calls over Wi-Fi or data, and works from any device with the Google Voice app or web client. Caveats: a small but growing list of US banks (Chase, Wells Fargo, Robinhood) refuse to send 2FA codes to Voice numbers because they detect VoIP. Test your critical accounts BEFORE you port — once the number leaves your carrier, you cannot easily port it back. Google Voice also requires you to log in from the US occasionally to keep the account active.

Option 2: Tello or US Mobile (cheap real SIM, $5–10/month)

Tello (T-Mobile MVNO) and US Mobile offer plans starting at $5/month for talk and text only, no data. This keeps your number on a real US carrier, so 2FA codes from banks that block VoIP still work. Pop the SIM into a spare unlocked phone, leave it on Wi-Fi calling at your US address (a family member's house works), and you'll receive SMS in your destination via Wi-Fi calling without roaming charges. This is the most bank-compatible setup and what most Americans abroad end up doing for banking-grade reliability.

Option 3: NumberBarn or Park My Phone ($2–5/month parking)

If you don't need to send SMS or take calls and just need the number to exist for occasional receive-only 2FA, parking services like NumberBarn ($2/month) and Park My Phone ($3/month) hold the number and forward voicemail to email. Most also support inbound SMS for an extra $1–2/month. Cheapest option for a 'keep it alive forever' setup, but the SMS support is hit-or-miss with bank 2FA — works for some senders, not others.

Option 4: Keep your existing carrier on a low plan

T-Mobile's basic plans include free texting and slow data in 200+ countries, which sounds perfect — but the line still costs $40–60/month. Verizon's TravelPass is $10/day, which adds up fast. Generally only worth it if you travel back to the US several times a year and want the same number to work on landing without swapping SIMs. For most full-time moves, porting out is cheaper.

Recommended setup for most movers

Belt-and-suspenders: port your old US number to Google Voice (free, handles 90% of accounts) AND get a $5/month Tello SIM with a new US number for the banks that reject Voice. Use the Tello number for new bank 2FA, the Google Voice number for everything legacy, and a local SIM in your destination for day-to-day. Total cost: ~$5/month. Set this up 30+ days before you move so you have time to update 2FA on every important account from inside the US, where carrier verification is easier.

What to do before you leave

Audit every account that sends you SMS codes: banks, brokerages, IRS.gov, Social Security, credit cards, email, password manager, Venmo/PayPal, and your state's DMV. Update the phone number on each one BEFORE you port or cancel your line — many require an SMS to the OLD number to authorize the change. Also enable an authenticator app (Authy, 1Password, Google Authenticator) wherever possible; it's strictly better than SMS 2FA and works from any country on Wi-Fi.

FAQ

Will my US bank know I'm abroad if I use Google Voice or Tello?

Not from the phone number alone — both present as US numbers. Banks detect foreign use mainly through login IP (use a US-based password manager autofill or, if needed, a US VPN endpoint) and address-of-record (keep a US mailing address, often a family member's, until you decide whether to update it).

Can I port my number to Google Voice from outside the US?

Yes, but the porting process requires receiving an SMS verification code on your existing US line, so do it while the line is still active — ideally before you move, or while visiting the US.

What about WhatsApp and iMessage?

Both stay linked to whatever number you register them with. If you keep a US number active via any of the methods above, WhatsApp and iMessage on that number continue to work normally from anywhere in the world over Wi-Fi.

Is Skype a viable option?

Microsoft is shutting down Skype consumer service in 2025. Don't build your phone strategy on it.
