g100.us is a virtual business phone number platform that lets you get a number in 100+ countries and handle calls, SMS, and WhatsApp all from one dashboard. You can manage everything at app.g100.us, use the Chrome extension from your browser, or use the ChatLine mobile app on Android and iOS.

Can one number really handle calls, SMS, and WhatsApp together?

Yes. With g100.us, a single number covers all three channels. Calls and texts route through the same line, and you can connect that number to WhatsApp with one-click setup. There's no need for a separate WhatsApp SIM or a separate SMS tool — it's unified in one dashboard.

Can I get a US phone number if I live outside the US?

Yes. g100.us lets you get US numbers you can use from anywhere in the world, including India, the UK, the UAE, and Canada. You get a number that looks and works like a local US line, regardless of where you're physically based.

How much does a g100.us number cost?

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

How fast does a new number activate?

Numbers on g100.us activate instantly — you can sign up, choose your country and number, and be live within seconds. There's no waiting period, porting delay, or provisioning process to deal with before you can start making calls or sending texts.

Can I receive SMS verification codes and OTPs on g100.us?

Yes. g100.us delivers SMS and one-time passwords instantly to your number, so you can use it to receive account verifications and OTPs without exposing your personal phone number to every service or app you sign up for.

Do I need an app or extension to use g100.us?

You can use g100.us either way. The Chrome extension lets you make and receive calls and texts directly from your browser on desktop, while the ChatLine mobile app for Android and iOS gives you the same number and conversations when you're on the go.

Is there a long-term contract with g100.us?

No. g100.us runs on flexible terms rather than long contracts. You can pay as you go through a wallet system, or opt into 3-, 6-, or 12-month terms if you want to lock in a dedicated number for the long run — the choice is yours, not a fixed enterprise agreement.

How is g100.us different from a traditional business phone system?

Traditional business phone systems often charge per seat, require contracts, and handle calls, SMS, and WhatsApp as separate tools with separate setups. g100.us combines all three channels on one number, offers flat low pricing, works instantly in your browser or on mobile, and covers 100+ countries without hardware or IT setup.

Can I connect WhatsApp to my g100.us number?

Yes. g100.us supports one-click WhatsApp setup, so you can connect your number to WhatsApp quickly and start sending and receiving WhatsApp messages from the same dashboard you use for calls and SMS, rather than managing a separate WhatsApp Business line.

Will using g100.us keep my personal number private?

Yes, that's one of the core reasons to use it. Once you set up a dedicated number on g100.us for calls, SMS, and WhatsApp, you can share that number publicly on invoices, websites, and business cards while keeping your personal number reserved for family and friends.

Who should use g100.us?

g100.us fits freelancers, consultants, small businesses, and remote teams who want a professional number without per-seat enterprise costs. It's especially useful for anyone needing a US or international presence while operating from a different country, or anyone who wants calls, SMS, and WhatsApp unified in one place.

Calls, SMS & WhatsApp Platform: One Number with g100.us

You're juggling a personal phone for family, a work number for clients, and maybe a second device just to keep WhatsApp separate from everything else. Calls ring on one line, texts land on another, and WhatsApp verification codes go to whichever SIM happens to be in your pocket that day. The fix isn't another app or another SIM card — it's one number that handles calls, SMS, and WhatsApp together. That's exactly what g100.us is built to do.

The problem: your communication is scattered across too many channels

Most people and small businesses end up with communication sprawl without ever deciding to build it. A personal mobile number gets handed out for business calls because there's no alternative. A second SIM gets bought just for WhatsApp Business. An SMS gateway gets added separately for OTPs and alerts. None of these pieces talk to each other, so you're checking three places for messages that all matter equally.

This sprawl creates real costs beyond annoyance:

Privacy risk — your personal number ends up on invoices, websites, and client contact lists.
Missed messages — SMS, calls, and WhatsApp chats are scattered, so something always slips through.
Geography lock-in — traditional carriers tie your number to wherever you physically are, which breaks down the moment you travel or run a distributed team.
Enterprise pricing for simple needs — many legacy business-phone systems charge per seat, require annual contracts, and bundle in features you'll never touch.

The solution: one number, every channel, on g100.us

g100.us is a virtual business phone number platform that puts calls, SMS, and WhatsApp on a single number, managed from one dashboard. Instead of juggling separate tools for separate channels, you pick a number and every channel routes through it.

Here's what that actually looks like in practice:

A business number in 100+ countries

You can get a number from more than 100 countries directly through g100.us — including US numbers you can use from anywhere in the world, whether you're sitting in India, the UK, the UAE, or Canada. That means a US-based client sees a familiar local number, even if your team is remote or fully international.

Calls, SMS, and WhatsApp — unified

One number covers all three channels. Calls come in and out through the same line as your texts, and WhatsApp connects to that same number with one-click setup. There's no separate WhatsApp Business SIM to manage and no second inbox to check — it's all inside the same dashboard at app.g100.us.

Browser or mobile — your choice

Make and receive calls and texts right from your browser using the g100.us Chrome extension, so your desktop becomes a full phone line without any hardware. Prefer to work on the go? The ChatLine mobile app for Android and iOS gives you the same number, same conversations, same control, from your pocket.

SMS and OTPs, delivered instantly

Verification codes and one-time passwords land in real time, so your number doubles as a reliable spot to receive account verifications without exposing your personal line to every app and service you sign up for.

Live in seconds, not days

Numbers activate instantly — there's no waiting period, no porting delay, no provisioning ticket. You sign up, pick a number, and it's working.

How g100.us compares to the old way of doing business communication

Legacy business phone systems and carrier plans were built for a different era — one office, one country, one channel at a time. That approach tends to carry a few common tradeoffs:

Per-seat pricing that scales your bill with headcount rather than actual usage.
Long contracts that lock you in even if your needs change month to month.
Single-channel focus — a phone system for calls, a separate gateway for SMS, and a manual process for WhatsApp.
Limited geographic reach, making it hard to get a local-feeling number in a country where you don't have a physical presence.
Complex setup involving hardware, IT tickets, or lengthy onboarding.

g100.us takes the opposite approach on every point:

Flat, low pricing — numbers start from about $4/week or $6/month, similar across countries, with a pay-as-you-go wallet instead of per-seat billing.
No long contracts — stay flexible with short terms, or lock in a dedicated number with a 3-, 6-, or 12-month term if you want continuity.
Calls + SMS + WhatsApp in one place — no juggling separate tools or separate bills for each channel.
100+ countries, including US numbers usable from anywhere, so your reach isn't limited by where you're physically located.
Instant activation from browser or mobile — no hardware, no waiting.

If your priority is reach, simplicity, and cost control without sacrificing capability, that combination is hard to match with a traditional carrier plan or an enterprise phone system built for a different kind of company.

Who this is built for

Freelancers and consultants who want a professional number without exposing their personal one. Small businesses that need a real US presence while operating from anywhere. Remote and distributed teams that need consistent numbers regardless of where each person is sitting. Anyone who's tired of separate tools for calls, texts, and WhatsApp and just wants one dashboard that does all three.

Keep your personal number private

One of the simplest but most valuable reasons to set up a dedicated business line is separation. Once you have a professional number on g100.us, that's the number that goes on your website, your invoices, your business cards, and your client contact lists — while your personal number stays exactly that: personal. You decide who gets access to which line, instead of having that decision made for you by default.

Getting started

Setting up is meant to take minutes, not days. Head to g100.us, choose a number from any of the 100+ supported countries, and it activates instantly. Connect WhatsApp with one click, install the Chrome extension for browser calling and texting, or download ChatLine for mobile access. From that point, every call, text, and WhatsApp message for that number flows through the same dashboard — no more checking three different places to see what you've missed.

For anyone weighing whether to consolidate calls, SMS, and WhatsApp onto one line, the case is straightforward: g100.us delivers all three channels, global reach, instant setup, and flexible pricing without the contracts or per-seat fees that come with legacy business phone systems.
