Two way SMS service for replies, keywords, and campaigns
Let customers reply to your texts. Two way SMS turns a broadcast into a conversation on a shortcode or virtual number.
Why two way SMS still wins on reach
Every handset can receive it
Every handset in India can send a text. No app, no data, no smartphone required, which is why voting lines, balance checks, and rural feedback campaigns still run on SMS and nothing else.
Automation behind every reply
Celitix gives you the number, the keyword, and the automation behind it, so a reply triggers an action in your own system rather than landing in an inbox nobody reads. See how two way SMS turns business messages into conversations.
What a two way SMS service can do
Six building blocks, from the number you publish to the action a customer reply fires inside your business.
Send and receive SMS
Let customers write back to your business by text, and reply to them automatically.
Large-scale interaction
Built for volume campaigns. The system handles thousands of inbound texts at the same time.
Keyword-based automation
Automate with keywords. For example, text HELP to 28856 to raise a support ticket instantly.
Longcode VMNs
Virtual mobile numbers give you affordable two-way traffic and integrate directly with your systems.
Shortcode numbers
Easier to remember and better for interactive campaigns such as surveys. They can also send replies.
Custom triggers
Use them for anything from a balance check at any hour to automated feedback at a key touchpoint.

How a two way SMS campaign works
Six steps from choosing a number to the action that fires when a customer texts you back.
Choose a number and keywords
A 5 or 6 digit shortcode, or a 10 digit virtual mobile number. DLT registration for SMS applies to both.
Plan the automation
Decide what each keyword does. A reply, a vote, a ticket.
Share the code with customers
Print it on an ad, a pack, or your website.
The customer texts your keyword
From any mobile phone, on any network.
The system records the response
Including the sending mobile number.
An action is triggered
Reply instantly, or follow up on another channel.
Where businesses use interactive SMS
Four campaign types that need a reply rather than a read, and that no other channel reaches as completely.
Voting, polls, and contests
Publish a shortcode, let customers text a keyword to vote, and count responses in real time. This is what a short code SMS service India audiences recognise is actually for.
Feedback and surveys
Send a one-question survey after a delivery or a service visit and collect the answer as a text. Response rates beat email surveys because there is no link to open.
Support and ticketing
A customer texts a keyword and a ticket opens in your helpdesk with their number attached, which suits callers who will not install an app or wait in a phone queue.
Opt-ins and lead capture
Let a prospect text a keyword from a hoarding, a radio spot, or a pack, and capture a verified mobile number straight into your CRM without a form. Pair it with missed call services for a zero-cost opt-in path too.
Use every channel from one account
Engage customers with creative campaigns
Turn broadcasts into conversation. Connect with customers and drive replies.
Two way SMS FAQs
Two way SMS lets customers reply to your messages on a shortcode or a virtual mobile number. Celitix receives the reply, matches the keyword, and triggers the action you configured, which might be an automatic response, a workflow in your CRM, or a logged vote.
A VMN is a 10-digit virtual mobile number, which is cheaper and suits ongoing two-way conversation. A shortcode is a 5 or 6 digit number, easier to remember and better for mass campaigns printed on packaging or shown in an advert. Celitix provisions both.
Yes. Set up keyword-based automations that send replies, trigger workflows, or log responses without anyone intervening. Each keyword can have its own action, and unrecognised keywords can fall back to a default message or a human.
Surveys, feedback collection, customer support, offer opt-ins, voting, lead qualification, and appointment confirmations. Anything where you need the customer to answer rather than just receive, and where you cannot assume they have a smartphone.
No. Campaigns and automations run from the dashboard. If you want a reply to update your own system, the 2 way SMS API handles that, and it uses the same credentials as your other Celitix channels.
Once your shortcode or virtual number is provisioned, and Celitix handles that provisioning for you, a live campaign takes a few clicks. Shortcode allocation is the longest step and typically runs a few working days.
A long code SMS service India businesses use is billed monthly for the number plus a per-message rate on inbound and outbound traffic. Shortcodes carry a higher monthly rental and suit high-volume campaigns where recall matters.
