How to Send SMS Text Messages from a Microsoft Access Database
Question details
The user needs a method to send automated SMS reminders to customers directly from a Microsoft Access database using a form button, without manually using a mobile phone.
- Product
- Microsoft Access
- Device & OS
- not provided
- Scenario
- Managing customer contact details and needing an automated, one-click solution to send text messages from an internal database form.
- Observed behavior
- Microsoft Access lacks a native, built-in SMS sending feature, requiring an external gateway or integration to process the text messages.
Ensure you have registered an account with a third-party SMS Gateway provider that offers a REST API (such as Twilio, Plivo, or Clickatell) and have your API credentials ready.
Integrate an SMS Gateway API using VBA
Use Visual Basic for Applications (VBA) to send HTTP requests to a third-party SMS gateway directly from your Access database.
Since Microsoft Access does not have built-in SMS functionality, the most reliable method is to use VBA to communicate with an external SMS provider's API. This method gives you complete control over message formatting and error handling.
Sign up for an SMS gateway provider of your choice. Navigate to their developer dashboard and copy your unique API key, Account SID, and dedicated sending phone number.
In your Microsoft Access database, press Alt + F11 to open the VBA editor. Go to Insert > Module to create a new module. Next, go to Tools > References and check 'Microsoft XML, v6.0' to enable HTTP requests.
Create a VBA function that accepts a phone number and message string as parameters. Use the MSXML2.XMLHTTP object to format a POST request containing your credentials and message data, sending it to the provider's API endpoint.
Open your Access form in Design View. Add a Command Button, open its Property Sheet, and click the ellipsis (...) next to the 'On Click' event to trigger your newly created VBA SMS function using the data from the current form record.
Use a Third-Party MS Access SMS Add-in
Install a pre-built Access add-in or plugin if you prefer not to write custom VBA code.

Frequently Asked Questions
Can I send an SMS directly from Microsoft Access without a third-party service?
No, Microsoft Access does not have any built-in SMS capabilities. You must connect your database to an external SMS gateway provider via an API or use a dedicated third-party add-in to route the messages.
Do I need to know VBA programming to send text messages from Access?
Writing a custom integration using an SMS API does require a basic understanding of Visual Basic for Applications (VBA) and HTTP requests. However, you can bypass coding entirely by purchasing and installing a pre-built SMS add-in designed for Microsoft Access.
How much does it cost to send SMS messages from an Access database?
The cost depends entirely on the SMS gateway provider you choose (such as Twilio, Plivo, or Clickatell). Most providers operate on a pay-as-you-go model, charging a fraction of a cent per message sent, plus an optional small monthly fee for a dedicated sending phone number.
Can I send bulk SMS messages to multiple customers at once from Access?
Yes. Once your VBA function or add-in is configured, you can create a loop in VBA that iterates through a recordset (such as a query containing multiple customer numbers) and triggers the API call for each contact in the list.
