The problem nobody warns you about
Registering a US company from abroad takes an afternoon. Getting a US phone number that behaves like a real one is where most people get stuck.
You can incorporate in Delaware or Wyoming without setting foot in the country. You can open a payment processor, ship from a US warehouse, and run ads to US customers. Then you hit the phone number — and discover it's the one piece that keeps tripping you up:
- Customers don't call foreign numbers. A +44 or +972 number on your contact page tells an American buyer this is an overseas operation. Many simply don't dial it.
- VoIP numbers get rejected. Plenty of US services refuse numbers that don't look like real mobile lines — and a growing number check.
- Carriers want paperwork you don't have. Walk into a US store and you'll be asked for an SSN, a US address, and often a US credit card.
- You're not physically there. Even with a number, you need to answer it from Manila, Lagos, Tel Aviv or São Paulo — at your customers' hours, not a call centre's.
What actually solves it
A real US carrier line, delivered as an eSIM to the phone already in your pocket. Not a forwarding service, not VoIP — an actual line on AT&T, T-Mobile, MobileX, LinkUp Mobile or Moxee, with its own US number.
What you need
Your phone's IMEI, an email address, and a payment method. That's the whole list.
What you don't need
No Social Security Number. No US address. No US bank account or credit card. No trip to the US. No second handset.
Wi-Fi calling: how the number follows you
This is the part most people don't realise is possible, and it's what makes a US number practical when you live somewhere else.
Wi-Fi calling routes your calls and texts over the internet instead of a nearby mobile mast. Your phone doesn't need to be near a US tower — it needs a data connection. Hotel Wi-Fi, your office, your home broadband: your US number rings there, and calls you make show your US number to the person receiving them.
In practice that means:
- A customer in Chicago dials your US number and your phone rings in Manila.
- You call them back and they see a US number, not an international one.
- Texts from your suppliers, banks and platforms arrive normally.
- Your personal number stays exactly where it is, on the same phone, on your existing SIM.
Who this is for
| If you're… | What the number does for you |
|---|---|
| Selling to US customers (e-commerce, SaaS, services) | A US contact number on your site and invoices, answered by you, wherever you are. |
| Running a US-registered company from abroad | A consistent line for suppliers, platforms and accounts tied to the business. |
| Freelancing or consulting for US clients | Clients call a local-looking number instead of paying international rates or avoiding the call. |
| Managing US-based staff or contractors | One number they can always reach, on your phone, without roaming charges. |
| Travelling to the US regularly | The same line works normally on the ground — no Wi-Fi, no VPN needed while you're there. |
Getting set up
- Pick a plan. Monthly US lines start from a few dollars; heavier talk, text and data plans cost more. All are on the plans page.
- Give us your IMEI. Dial
*#06#on the phone you'll use. If it's a dual-SIM phone, use the second IMEI — that's the one belonging to the eSIM. - Pay. Card, Apple Pay, Google Pay, Alipay, WeChat Pay or crypto.
- Install. Most carriers email a QR code within minutes. Some activate straight onto your handset over the air, in which case there's nothing to scan — the line simply appears.
- Turn on the US VPN and Wi-Fi calling, then make a test call.
Common questions
Is it really a carrier number, not VoIP?
Yes. The line is issued by a US carrier and behaves like any other US mobile number, which matters for the services that reject VoIP.
Can I keep it long-term?
Yes — recharge it and the number stays yours. Let a prepaid line lapse and the carrier eventually releases the number, so keep it topped up if the number matters to your business.
Do I need to change phones?
No. It installs as an eSIM next to your existing SIM. Your home number keeps working.
What if my phone isn't compatible?
Most phones from 2019 onward support eSIM. Enter your IMEI on the plans page and we'll check it before you pay.
Does it work when I'm actually in the US?
Yes, and more simply — it connects to the carrier's network directly, with no Wi-Fi or VPN needed.
