If you freelance or sell online from Sri Lanka, you already know the problem. Your clients are in the US, the UK, Australia. They want to WhatsApp you, they need to reach you on a number that looks professional, and half the tools you sign up for want to text an OTP to a "+1" number you don't have. A local Dialog or Mobitel number works fine for your friends — but for overseas clients, a US number just lands differently.
So the search begins. "Free US number." You install Google Voice. It won't open. You try TextNow. Blocked at sign-up. A weekend gone, nothing to show. Let me spare you that. Here is what the cheapest working option actually looks like from Colombo, and how to get it in about twenty minutes.
This is the bit nobody warns you about before you burn your data. The popular free number apps were built for people already living in North America. From a Sri Lankan connection, they quietly refuse to let you in.
People try VPN tricks to fool these apps. Sometimes a number appears — then it can't receive the WhatsApp code, or the account gets flagged and wiped a week later. When your client relationships live on that number, it's not a risk worth taking.
To be fair, apps like Hushed and Vyke are legitimate and do let people abroad buy numbers. They're worth knowing about. But they cover a limited set of countries and their per-number pricing tends to run higher, so for a Sri Lankan freelancer watching every rupee, they're rarely the cheapest way in.
| Works from Sri Lanka? | Price | WhatsApp-ready? | Receive OTP? | |
|---|---|---|---|---|
| G100 | Yes — buy from anywhere | $1.95/month, no contract | Yes — receives the code | Yes — SMS & OTP land in your inbox |
| Google Voice | No — not available | Free (but unreachable here) | N/A — no number | N/A — no number |
| TextNow | No — US/Canada sign-up only | Free (but unreachable here) | N/A — no number | N/A — no number |
| Hushed / Vyke | Often yes (limited countries) | Paid, usually higher | Varies by number | Varies by number |
The plain truth: a "free" number you can't reach costs you more than a working one that costs under $2 a month. Cheapest is not the smallest sticker price — it's the smallest price that actually gets you a number.
Be honest about the job. As a Sri Lankan freelancer or seller, you usually need three things from a US number: run WhatsApp Business so clients can chat you on a professional line, receive OTP codes from overseas platforms that only text US numbers, and take the odd call from a client. All three come down to one requirement — the number must be able to receive an SMS or a call. Meta does the WhatsApp verifying; the platform sends the OTP; the number just has to catch the code. A G100 US or Canada number does exactly that, from Sri Lanka, no VPN games.
The same inbox is where your overseas-platform OTPs will land later — sign up for that Stripe, PayPal-style, or SaaS account that wants a US number, and the code shows up in the same place.
One honest heads-up: right now G100 numbers receive SMS and OTP codes — which is everything you need for WhatsApp verification and for receiving one-time passwords. Sending your own outbound SMS from the number is not switched on yet (it's coming after US 10DLC verification clears). So for WhatsApp sign-up, calls, and receiving codes you're fully covered today. If sending plain outbound texts is critical for you, know that one piece is still on the way.
Once you're verified, don't leave the profile empty. Add your business name, a category, your logo, your working hours, and a short greeting so a first-time client gets a reply even while you sleep — remember they may be twelve hours behind you. A US number attached to a filled-out, professional profile is what turns a curious lead into a client who trusts you with real work.
If you later grow into a small team sharing one number, or you want to send broadcasts to your client list, G100 also offers the official WhatsApp Business Cloud API as a $10/month add-on. Start with the phone app, and only upgrade when you genuinely need it.
A G100 US number is a flat $1.95 per month with no contract, and you can buy it from anywhere in Sri Lanka. There is no cheaper working option that also lets you receive WhatsApp and OTP codes — the free apps like Google Voice and TextNow simply do not let you register from Sri Lanka at all.
Google Voice is not available in Sri Lanka or most of Asia, so you cannot get a number to begin with. TextNow only allows sign-ups from the United States and Canada, so it blocks registration from a Sri Lankan connection. Both are dead ends from Colombo, Kandy, or anywhere on the island.
Yes. A G100 US or Canada number receives SMS and OTP codes right inside your inbox at app.g100.us, so you can verify WhatsApp Business and receive one-time passwords from overseas services while sitting in Sri Lanka. You can also make and receive calls on the number.
No. G100 does not ask for KYC or documents to get a US, Canada, or Puerto Rico number. You sign up, pick a number, fund your wallet in USD through Stripe, and activate — that's the whole process.
Not yet. Today G100 numbers receive SMS and OTP codes, make and receive calls, and work with WhatsApp Business — which covers verification and receiving codes. Outbound SMS sending is not switched on yet; it comes after US 10DLC verification clears.
