Change countries, SIMs and Wi-Fi as often as you like. Your US number stays the same.
Digital nomads use a US virtual number as the one number that does not change when they move. The TripoSIM number rings in an app over Wi-Fi or any local SIM or eSIM with data, receives verification codes (OTP SMS) from apps, and has voicemail. It includes 300 minutes a month to the US and Canada. It cannot call 911, so get a local SIM for emergencies.
Your phone number ends up everywhere: bank and payment accounts, app sign-ins, client contracts, family contacts and the services you still use back home. If you rely on a new local SIM in each country, that number changes every few months, and every account that knows the old one falls behind.
A US number in an app does not depend on the SIM in your phone. Swap SIMs at each border, and the TripoSIM number keeps ringing, as long as the app has internet. Contacts, clients and accounts keep one number for you.
Think of it as two layers. Data comes from whatever is local: Wi-Fi at your apartment or coworking space, a local SIM, or a travel data eSIM. The number comes from the TripoSIM app, which uses that data. On iPhone, add the TripoSIM web app to your Home Screen. On Android, install the TripoSIM app.
| Part | What it gives you | What it does not do |
|---|---|---|
| Local SIM or eSIM | Mobile data in that country; a local SIM with a number also lets you call local numbers, including emergency numbers | Changes with every country |
| Wi-Fi | Internet for calls in the app at home or at work | Nothing once you are out of range |
| TripoSIM US number | A +1 number that stays the same: calls, voicemail, US texts and verification codes | It cannot send texts or call 911 |
Most travel eSIMs are data only and do not come with a number. Our guide to eSIMs and US numbers explains the three kinds of product, and the nomad phone setup walks through it step by step.
Yes. The codes go to your US number, not to the SIM in your phone, so they arrive in the app wherever you are online. The number receives verification codes (OTP SMS) from apps, including WhatsApp. TripoSIM tested 22 apps in October 2026; the list gives examples, not a limit. See how to get codes quickly.
Calls to you are included up to a fair use of 300 minutes a month. Only calls you make to US and Canadian numbers use your 300 minutes. Three typical ways of living on the move, worked out for a year:
| Example | Calls out to the US and Canada | Extra minutes | One year on the yearly plan |
|---|---|---|---|
| Admin calls home | 1 call a week to a bank, insurer or doctor, 15 minutes: about 65 minutes a month | None: within the included minutes | $100 |
| Clients and family | 3 calls a week, 20 minutes each: about 260 minutes a month | None: within the included minutes | $100 |
| Daily calls home | 7 calls a week, 15 minutes each: about 455 minutes a month | 19 × $5 = $95 a year | $195 |
Incoming calls do not use your minutes (fair use 300 minutes a month). Each plan includes 300 minutes a month out; extra minutes are $5 per 100, and unused extra minutes carry over to the next month, so the year counts the packs for all 12 months together. Prices before tax.
Calls to local numbers in the country you are in go through your local SIM, not the US number. Try your own pattern in the cost calculator.
On a flight, at a border or while you swap SIMs, the app may be offline. Callers then reach voicemail. Messages can be up to 2 minutes, up to 30 a month, kept 30 days. Your time zone changes often, so record a greeting that does not need updating: "I'm based outside the US and return calls within one US business day."
Some countries or networks restrict internet calling. Test a call in and a call out when you arrive, on Wi-Fi and on local data.
If you plan to keep the number for a year or more, the yearly plan is $100 and includes $5 of credit for travel eSIM data or extra minutes. The monthly plan is $12.99 if you want to try it first. Keep your payment card up to date. If a plan ends, the number is kept 30 days on the yearly plan or 90 days on the monthly plan, then released, and every account that uses it loses its contact number.
