2-Way SMS is a communication method that lets businesses both send and receive text messages, creating a real-time dialogue with customers. Unlike traditional one-way messaging, it turns every SMS into a conversation — enabling customers to reply, confirm, ask questions, or provide feedback directly from their phone.
Businesses across every industry rely on a two way SMS service to power their most critical communication workflows. Whether you are running large-scale marketing campaigns, handling customer support inquiries, automating OTP verification, collecting post-purchase feedback, or generating new leads, SMS replies give you a direct, high-engagement channel that email and social media simply cannot match.
We provide virtual phone numbers with international coverage that can be easily integrated into applications, enabling both P2A (Person-to-Application) and P2P (Person-to-Person) communication. With EasySendSMS, you can start receiving SMS replies in minutes — no hardware, no complexity.
We offer two flexible options to receive SMS online, each designed for different stages of your business. Choose the one that fits your needs — or use both.
Our shared SMS inbox lets you receive inbound SMS using a shared virtual number from our pool. Because the number is shared among multiple users, your customers need to include your unique username at the start of their message so the reply is routed to your account.
Message format: #username your message text
Why use the Shared Inbox?
For a professional, branded experience, purchase a private virtual phone number. A dedicated number belongs exclusively to your account, so customers can reply directly — no keyword or special format needed. It is the preferred choice for businesses running campaigns, providing support, or handling SMS verification.
Why use a Dedicated Number?

Virtual numbers are phone numbers that exist in the cloud — they are not tied to a SIM card or physical device. They were designed for the business market, enabling you to receive replies to the SMS messages you send, accept incoming messages for verifications (such as WhatsApp, WeChat, and other mobile apps), and maintain a professional point of contact for your customers.
You can start with our free shared virtual SMS numbers to receive incoming replies using your inbound keywords. When you are ready to scale, purchase a dedicated number and configure your own keywords for complete control over your inbound SMS service.

2-Way SMS is a messaging technology that allows businesses to both send and receive text messages, creating real-time, bidirectional conversations with customers. Unlike one-way bulk SMS, it enables customers to reply, ask questions, confirm appointments, and provide feedback — all through standard text messaging.
You can receive SMS online by using a virtual phone number from EasySendSMS. We offer two options: a free shared SMS inbox that uses a keyword-based format (#username message), or a dedicated virtual number that receives messages directly without any keyword requirement.
An SMS virtual number is a cloud-based phone number that is not tied to a physical SIM card or device. It can be used to send and receive SMS messages from a web dashboard or through an API, providing a professional and consistent point of contact for your business.
A shared SMS inbox allows multiple users to receive inbound messages on the same virtual phone number. To route messages correctly, the sender includes a unique username or keyword at the beginning of their text. It is a free, no-commitment way to test our inbound SMS service before purchasing a dedicated number.
Yes. With a virtual phone number from EasySendSMS, you can receive SMS messages directly in our web dashboard or have them forwarded to your application via our HTTP API webhook. No physical phone or SIM card is needed.
Absolutely. Our platform supports automated replies triggered by keywords, message content, or custom rules. This is ideal for instant customer service, opt-in confirmations, appointment reminders, and answering frequently asked questions — all without manual effort.
SMS keyword routing lets you assign specific words (like "HELP", "JOIN", or "DEALS") to trigger different actions when a customer texts them to your number. Keywords can be used to sort messages into categories, trigger auto-responses, subscribe users to lists, or route inquiries to the right team.
An inbound SMS API (also called a webhook) is a developer tool that pushes incoming SMS messages directly to your application in real-time. When a customer sends a message to your virtual number, our HTTP API delivers the message data to a URL you specify, allowing you to process, store, and respond to it programmatically.
A shared virtual number is free and used by multiple users — senders must include a keyword to route messages to the correct account. A dedicated virtual number is exclusive to your business, allowing customers to reply directly without any keyword. Dedicated numbers are recommended for campaigns, support, and professional branding.
Getting started is simple. Create a free EasySendSMS account, and you can immediately begin testing with our shared virtual number. When you are ready for a dedicated number, browse our virtual number catalog and purchase one that fits your needs. Our developer documentation will help you integrate in minutes.
Try our shared free virtual SMS number to test the service — no credit card required. When you are ready, upgrade to a dedicated number for a seamless, professional experience.
