SMS and RCS

Bulk SMS and SMS API for Colombia

Campaigns, alerts, reminders and conversations over SMS, from our portal or straight from your systems over an API or SMPP. With trackable short links and per-⁠message delivery reports.

Benefits

  • Reaches any mobile phone

    SMS needs no data connection or app: any active mobile line can receive it.

  • Built into your systems

    Send from the portal, or integrate our REST API and SMPP to trigger messages from your CRM, core platform or app.

  • Every message traceable

    Per-⁠message delivery receipts and click tracking on your short links, so you know what worked.

What’s included

Bulk SMS campaigns

Send promotions, announcements and updates to large contact lists, personalized and scheduled.

Related

  • List upload

    Upload contacts from a file or sync them over the API.

  • Personalization

    Per-⁠recipient variables inside the text.

  • Scheduling

    Send now or at a set date and time.

  • Opt-⁠outs

    Manage recipients who no longer want your messages.

Upload your list, write the message with variables such as name or amount, and send it now or schedule it. When the campaign ends you see how many messages were delivered and how many failed.

Marketing and collections messages require the recipient’s consent and must follow the channels and hours set by Colombia’s Law 2300 of 2023.

Transactional SMS and alerts

Messages your systems trigger the moment something happens: a payment, an order, an appointment.

Related

  • Event-⁠triggered

    Your system sends in real time over the API.

  • Alerts and notices

    Payments, account activity, order status and service outages.

  • Reminders

    Appointments, due dates and renewals.

  • Message tags

    Split your reports by message type.

Transactional SMS goes out one at a time in response to an event. Use it for confirmations, security alerts, reminders and service notices your customers expect.

For one-⁠time verification codes, see the OTP section under Security and verification.

Two-way SMS and short codes

Customers reply to your message and the response lands in your system.

Related

  • Inbound replies

    Receive what the customer replies.

  • Short code

    Short numbers for keyword campaigns.

  • Events to your system

    Every reply arrives as a webhook.

Two-⁠way SMS lets customers confirm with a “YES”, send keywords or start a conversation. Replies reach you as webhook events so your system can act without manual work.

A short code is an easy-⁠to-⁠remember number of just a few digits, ideal for keyword campaigns and reply-⁠based services.

Short code assignment follows Colombian CRC regulations and may involve additional steps.

SMS API and SMPP

Embed SMS sending in your software with our REST API, or use SMPP for high volume.

Related

  • REST API

    Key-⁠based authentication and JSON responses.

  • SMPP

    Persistent binds for high throughput.

  • Delivery receipts

    Status of every message by webhook.

  • Separate keys

    Independent credentials per integration.

The REST API sends a message with a single authenticated HTTP request and returns delivery receipts by webhook. SMPP is the industry-⁠standard protocol for persistent, high-⁠volume connections, common among platforms and aggregators.

RCS Business Messaging

We are evaluating RCS, the evolution of SMS with verified branding, images and buttons, for projects where it adds value.

Related

  • Branded sender

    Verified logo and name.

  • Rich content

    Images, cards and reply buttons.

  • SMS fallback

    If the phone does not support RCS, it arrives as SMS.

RCS delivers rich messages inside the phone’s native messaging app, with nothing extra to install. Its reach depends on the recipient’s carrier supporting it and on the device having it enabled, so we assess it case by case and pair it with SMS as a fallback.

Subject to the policies, eligibility and availability of each platform, carrier and device. Assessed for each project.

Step by step

How it works

  1. Open your account

    Sign up and we set up your sender and message type with you.

  2. Choose how to send

    From the portal for campaigns, or over the API and SMPP from your systems.

  3. Send and receive replies

    Messages go out and, if you set it up, replies flow back into your system.

  4. Measure the results

    Review deliveries, failures and link clicks to fine-⁠tune your next campaign.

Frequently asked questions

Can I send SMS without any integration?

Yes. In the portal you upload your list and send the campaign. The API and SMPP are for when you want your systems to send automatically.

Why do accented characters use more SMS segments?

Some accented characters, such as á, í, ó and ú, force Unicode encoding, which allows 70 characters per segment instead of 160. Characters like ñ and é are part of GSM-⁠7, so they do not change the length.

What do I need for collections or marketing SMS?

The recipient’s consent, and compliance with the channels and contact hours set by Law 2300 of 2023. We recommend keeping a record of those opt-⁠ins and always honoring opt-⁠outs.

What is the difference between the API and SMPP?

The REST API is the simplest way to integrate: one request per message. SMPP keeps a persistent connection open and is the usual choice for platforms sending high, steady volumes.

How much does SMS cost?

Pricing depends on volume and message type. Tell us about your use case and we will send you a proposal.

Are you a reseller or an operator?

We are a licensed Colombian telecommunications operator, founded in 2009. If you are a carrier or aggregator looking for A2P routes, see our wholesale A2P SMS page.
