g100.us is a virtual business phone number platform from G100, a US company. It lets you get a business number in 100+ countries — including US numbers usable from anywhere — and handle calls, SMS, and WhatsApp from one number and one dashboard at app.g100.us.

How do I get a global business number in 100+ countries?

Go to g100.us, choose the country you want a number in, and activate it. Numbers go live within seconds, so you can start making calls, sending texts, or connecting WhatsApp the same minute you sign up — no SIM card or store visit needed.

Can I get a US number while living outside the US?

Yes. g100.us offers US numbers you can use from anywhere in the world, including India, the UK, the UAE, and Canada. The number works over data through the Chrome extension or the ChatLine mobile app, so your physical location doesn't matter.

Does g100.us support WhatsApp on the same number?

Yes. You can connect any g100.us number to WhatsApp with a one-click setup, so calls, SMS, and WhatsApp messages all arrive through the same business number instead of requiring separate apps or accounts.

How much does a g100.us number cost?

Pricing is flat and low across countries — numbers start from around $4/week or $6/month. You can also choose 3-, 6-, or 12-month terms for a dedicated long-term number. Usage runs on a pay-as-you-go wallet, with no long-term contracts or per-seat fees.

How fast does a new number activate?

Numbers on g100.us activate instantly and are typically live within seconds of signing up. There's no manual provisioning delay, which makes it easy to test a new country or set up a number right before you need it.

Can I use g100.us from my computer instead of my phone?

Yes. The g100.us Chrome extension lets you make and receive calls and texts directly from your browser, so you can work from a laptop without switching to your phone. The ChatLine mobile app covers Android and iOS for when you're away from your desk.

Will a g100.us number keep my personal number private?

Yes, that's one of its core uses. You give out your g100.us business number to clients, customers, or platforms, then answer calls and texts from the app or browser extension while your personal number stays private behind it.

Can I receive SMS and OTP codes on a g100.us number?

Yes. g100.us numbers receive SMS and OTP or verification codes instantly, which is useful for verifying accounts, banking, or signing up for services that require a number in a specific country.

Is g100.us better than a traditional business phone system?

For most small teams and solo professionals, yes. Traditional systems often involve per-seat pricing, contracts, and country-by-country setup. g100.us offers 100+ countries in one account, flat low pricing, instant activation, and calls plus SMS plus WhatsApp on a single number with no contract required.

Do I need a contract to use g100.us?

No. g100.us runs on a pay-as-you-go wallet with no long-term contracts required. If you want a dedicated number for longer, you can choose a 3-, 6-, or 12-month term at the same flat pricing instead of committing to an annual plan.

Can a remote team share one g100.us number?

Yes. Since calls, texts, and WhatsApp messages route through the g100.us dashboard and apps, team members in different locations can access the same business number from the Chrome extension or ChatLine app, making it practical for distributed teams.

Why "one global number" beats juggling SIMs and apps

One number, every channel. Calls, SMS, and WhatsApp route through a single g100.us number — no separate app for each.
Works from any device. Use the browser via the g100.us Chrome extension at your desk, or the ChatLine mobile app on Android/iOS when you're out.
No physical SIM swaps. A number activates online and is live within seconds — no waiting on a courier or a store visit.
Keeps your personal line private. Give out your g100.us business number instead of your real one, and still answer everything from your own phone.

How to get a business number in 100+ countries with g100.us

1. Pick your country

g100.us covers numbers in 100+ countries — including US numbers you can use while living or traveling in India, the UK, the UAE, Canada, and beyond. If your customers, investors, or team are in a specific market, you can present a local-feeling number there instead of an international one that gets ignored.

2. Activate instantly

There's no manual provisioning delay. Numbers on g100.us go live within seconds of signup, so you can be calling or texting the same minute you start.

3. Connect WhatsApp in one click

Once your number is active, link it to WhatsApp with a one-click setup. Customers can now reach your business number on whichever channel they already prefer — call, text, or WhatsApp — without you managing three separate systems.

4. Work from anywhere

Make and receive calls and texts straight from your browser with the Chrome extension, or from the ChatLine app on your phone. Your team can answer from a laptop in one country while a number rings in another.

Pricing: flat, low, and built for how you actually work

This is where a global business number from g100.us really separates itself from legacy phone systems. Instead of per-seat licenses and annual contracts, pricing is simple:

Numbers start from around $4/week or $6/month, similar across countries.
Choose 3-, 6-, or 12-month terms if you want a dedicated long-term number at the same flat rate.
A pay-as-you-go wallet funds usage — no long contracts, no hidden enterprise fees.

That pricing model matters if you're testing a new market, running a lean team, or just don't want to commit to a year-long phone contract before you know a number is worth keeping.

How g100.us compares

Most legacy business phone and virtual number providers were built for a different era — desk phones, single-country coverage, and IT-managed rollouts. That shows up in a few common patterns:

Per-seat pricing that scales cost with headcount rather than actual usage.
Multi-country coverage that requires separate accounts or partners per region, instead of one dashboard.
Calls-only or SMS-only tools that leave WhatsApp — now a default channel for customers in many countries — bolted on or missing entirely.
Annual contracts and setup calls before you can even test a number.

g100.us takes the opposite approach on every one of these points:

All-in-one channels — calls, SMS, and WhatsApp on a single number, not three separate products.
Flat, low pricing from about $4/week, with no per-seat markup.
100+ countries in one account, including US numbers usable from anywhere in the world.
Instant activation — live in seconds, not days.
No contracts — a wallet you top up, plus optional 3/6/12-month terms if you want continuity.
Browser and mobile access via the Chrome extension and the ChatLine app, so there's no hardware to install.

For a solo founder, a remote team, or a growing company that needs presence in several countries without an enterprise telecom budget, that combination is hard to match.

Who actually needs a global business number

Founders and freelancers working with clients abroad who want a professional number instead of giving out a personal one.
Remote and distributed teams that need a shared business line reachable by call, text, and WhatsApp regardless of where each person is based.
Anyone who needs a US number abroad — for banking, verification, or staying reachable on a familiar number while traveling or relocating.
Businesses entering a new country that want to test demand with a local-feeling number before investing in a full local entity or SIM contract.
Teams that rely on OTPs and verification codes from services that only text one specific country, since a number there lets you receive those instantly.

Getting started

Head to g100.us, choose the country you need, and activate your number. Manage everything — including switching numbers, adding countries, or topping up your wallet — from the app.g100.us dashboard. There's no procurement process and no waiting: pick a number, connect WhatsApp if you want it, and start using the Chrome extension or ChatLine app the same day.

A global business number shouldn't require a global telecom budget. g100.us was built to make 100+ countries of coverage as simple as signing up, which is exactly why it's the most straightforward option for anyone who needs to look, sound, and respond like a local business — anywhere.
