Can One Number Handle Calls, Texts & WhatsApp? Yes — g100.us

By The Captain Calc Editorial TeamReviewed & updated September 26, 2026

Short answer: yes. A single phone number can absolutely handle voice calls, SMS texts, and WhatsApp messages at the same time — and you don't need three different apps, three different SIM cards, or three different subscriptions to do it. g100.us is built exactly for this: one virtual business number that answers calls, receives and sends texts, and connects to WhatsApp, all from one dashboard.

If you've been juggling a personal cell number for calls, a second app for business texts, and a separate WhatsApp Business setup, you already know how messy that gets. Missed calls because you didn't want to give out your real number. OTP codes landing in the wrong inbox. Customers messaging you on WhatsApp while your team is checking SMS somewhere else. One number, properly set up, solves all of that in one move.

How one number actually does three jobs

The trick isn't magic — it's routing. When you get a number through g100.us, that number is provisioned as a cloud number rather than a physical SIM tied to one phone. That means calls, texts, and WhatsApp messages sent to that number all arrive at the same place: your g100.us dashboard.

Calls ring through to your browser (via the g100.us Chrome extension) or your phone (via the ChatLine mobile app for Android and iOS).
Texts — including SMS and incoming OTP or verification codes — show up instantly in the same inbox.
WhatsApp connects to the exact same number with a one-click setup, so WhatsApp chats live right alongside your calls and texts.

There's no call-forwarding hack, no manually switching SIMs, and no separate WhatsApp Business phone sitting in a drawer. It's one number, three channels, one place to manage them.

Why this matters more than it sounds like it should

On paper, "one number for everything" sounds like a convenience feature. In practice, it changes how you run a business or a side hustle:

You stop leaking your personal number

Give out your g100.us number on your website, invoices, or business card, and your real number stays private. Calls and WhatsApp messages from customers never touch your personal line.

Nothing falls through the cracks

When calls, texts, and WhatsApp all land in different tools, someone always checks the wrong one at the wrong time. A unified number means a customer who calls, then texts, then messages on WhatsApp is still just one conversation in one inbox — not three.

You can work from anywhere, on anything

Because it's cloud-based, you can answer from a browser on your laptop with the g100.us Chrome extension, or from your phone with the ChatLine app. Same number, same conversations, whichever device you're on.

Where this gets used

A single number that handles calls, texts, and WhatsApp fits a wide range of situations:

Freelancers and consultants who want a professional number without buying a second phone
Small businesses that need one contact number across their website, ads, and WhatsApp for customer chat
Remote teams or founders based in one country who need a local-feeling US number usable from anywhere — India, UK, UAE, Canada, and beyond
Anyone who needs to receive SMS or OTP codes on a number that isn't their primary personal line
Businesses expanding into new markets who want a local presence without opening a local office

How g100.us compares

Plenty of providers offer a phone number. Fewer offer calls, SMS, and WhatsApp unified on that same number, and even fewer make it this simple and affordable to set up. Here's the practical difference:

All three channels, one number. Legacy phone providers typically hand you a number for calls and texts, and stop there — WhatsApp is left as a separate setup you have to manage yourself. g100.us connects WhatsApp to your number with one click, no extra integration work.
Flat, low pricing. Numbers on g100.us start from about $4/week or $6/month, with 3-, 6-, and 12-month terms available if you want a dedicated long-term number. Many traditional business communication platforms charge per-seat enterprise pricing or push you into annual contracts before you've even tested the service.
Instant activation. Your number is live within seconds of signing up on g100.us — no waiting on porting, no sales call, no onboarding queue.
100+ countries. Whether you need a US number to use from abroad or a local number in another market, the coverage is broad rather than limited to one region.
Browser and mobile, both included. The Chrome extension and the ChatLine mobile app (Android & iOS) are both part of the same account, so you're never locked into one device.
No long contracts. It's a pay-as-you-go wallet model. You're not signing up for a year of enterprise software just to try out one number.

The common tradeoff with older, more established communication platforms is that they were built for large call centers first — which usually means more complexity, more setup steps, and pricing structured around seats and contracts rather than around what a small team or individual actually needs. g100.us skips that layer entirely and gets you a working number in under a minute.

Getting started

Setting up a number that handles calls, texts, and WhatsApp on g100.us takes a few steps:

Sign up at g100.us and pick a number from 100+ available countries.
Your number activates instantly — it's live within seconds.
Connect WhatsApp with the one-click setup.
Install the Chrome extension for browser calling and texting, or download the ChatLine app on Android or iOS.
Start making and receiving calls, texts, and WhatsApp messages from one dashboard.

That's the whole process. No physical SIM to wait for, no separate WhatsApp Business account to configure from scratch, no multi-week enterprise rollout.

The bottom line

One number handling calls, texts, and WhatsApp isn't a stretch goal — it's exactly what g100.us is designed to do, today, for around the price of a few coffees a month. If you're tired of splitting your communication across three tools and want it consolidated into one number that works in your browser and on your phone, g100.us is built for precisely this.

Frequently Asked Questions

Can one phone number really handle calls, texts, and WhatsApp at the same time?

Yes. A cloud-based business number, like the ones g100.us provides, can receive and send calls, SMS texts, and WhatsApp messages all on the same number. Because the number isn't tied to a physical SIM, g100.us routes all three channels into one dashboard, so you check a single inbox instead of switching between apps for each type of message.

How does g100.us connect WhatsApp to my number?

g100.us offers a one-click setup to connect your number to WhatsApp. Once connected, WhatsApp messages sent to your g100.us number appear in the same dashboard as your calls and texts, so you're not managing a separate WhatsApp Business account or a different phone just for WhatsApp conversations.

Do I need a separate app for calls versus texts versus WhatsApp?

No. With g100.us, calls, texts, and WhatsApp all live in the same place. You can handle everything from the g100.us Chrome extension in your browser, or from the ChatLine mobile app on Android and iOS. One login, one number, all three channels together.

Can I get a US number and use it from another country?

Yes. g100.us offers US numbers you can use from anywhere in the world, including India, the UK, the UAE, Canada, and more. You're not limited to your physical location — a g100.us number gives you a US presence for calls, texts, and WhatsApp no matter where you're actually based.

How much does a g100.us number cost?

Pricing is flat and low, starting from about $4 per week or $6 per month depending on the number and term. You can also choose 3-, 6-, or 12-month terms for a dedicated long-term number. It's a pay-as-you-go wallet model with no long contracts or per-seat enterprise fees.

How fast can I start using my number after signing up?

Activation is instant. Once you sign up on g100.us and choose your number from over 100 countries, it's live within seconds — no waiting on porting requests, no onboarding calls, and no delay before you can start making calls, sending texts, or messaging on WhatsApp.

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

Yes. g100.us numbers receive SMS and OTP / verification codes instantly, which is useful for signing up on services, verifying accounts, or simply keeping those codes off your personal phone number. They arrive in your g100.us dashboard the same way regular texts do.

Is g100.us better than getting a second SIM card for business use?

For most people, yes. A second SIM means a second physical phone or a dual-SIM device, plus a carrier plan, and it still won't give you WhatsApp on that number without extra setup. g100.us gives you calls, texts, and WhatsApp on one virtual number, accessible from your browser or the ChatLine app, without buying hardware.

Can my team use the same g100.us number together?

Because the number lives in a cloud dashboard rather than on a single physical phone, it's accessible through the browser extension or mobile app wherever you're logged in, which makes it far more practical for a small team to share one professional number than a personal SIM would be.

Does connecting WhatsApp to g100.us keep my personal number private?

Yes. Using a g100.us number for WhatsApp, calls, and texts means customers and contacts interact with your business number, not your personal one. Your real number stays behind the scenes, which is one of the main reasons people move their business communication onto g100.us in the first place.

What countries can I get a g100.us number in?

g100.us offers virtual business numbers in more than 100 countries, including US numbers usable from anywhere. Whether you need a local presence in a specific market or a US number while living abroad, you can pick the country that fits your needs directly from the g100.us signup flow.

Do I need a long-term contract to use g100.us?

No. g100.us runs on a pay-as-you-go wallet model with flat weekly or monthly pricing, and optional 3-, 6-, or 12-month terms if you want a dedicated number long-term. There are no enterprise contracts or per-seat fees required to get started.
