You can buy credits for any number of messages. Choose the number of SMS messages you want to send.

The second step is to choose the method of payment: credit card or bank transfer. Follow the instructions to complete the checkout.

Payment with card is immediate and credits will be added automatically and instantaneously to your account once the transaction has been completed.

Address book

The WebSMS application also features an address book of contacts with multiple functions and features.

The address book allows you to access your contacts and classify them into groups. Each entry includes name, number and group, and you can add optional custom fields. You can also insert contacts, delete a group, edit contact fields etc.

Create custom fields for contacts. Any field in the address book can be included in a message as a variable.

There is also a section for sending SMS messages to contacts in the address book. Just select the groups or individual contacts who you want to send messages to.

Import contacts

Bulk import contacts via CSV file (Excel) or copy and paste from any application.

Importing contacts or telephone numbers can be done through a text file CSV (Excel) or copying and pasting address books from other applications.

In the IMPORT section, copy the column of numbers in the corresponding text field, choose a name for the group and click import. Easy and effective, in just a few seconds you'll find all your contacts integrated into WebSMS.

Sending scheduled messages

There is always the option to schedule message delivery for a specific day and time. All sent messages are stored in the SCHEDULED section where you can view and cancel them.

The scheduled messages section displays all the relevant fields: number of messages to send, the text of the message, the time/date of creation, and time/date sent.


You can check the statistics of sent and received messages at any time. Statistics are displayed in graphs showing the number of messages sent by day, month, time, messages confirmed and bulk messages sent etc.

The data displayed in the statistics can be filtered by date, and you can activate visual charts and graphs.

Message to message monitoring

One of the best features of WebSMS is the ability to check the status and information of each sent message.

You can search for an SMS by any field attached to the message: telephone number, text, date/time, sender etc.

You can see all the information of each message, including the confirmation and time of delivery.

The results are displayed as a list alongside all the relevant fields: text, telephone number, contact name, date sent, etc.

All results can be exported as a CSV file, which can be opened in Excel for further analysis or study.


The predefined templates are messages saved as templates for later use. All the forms for sending messages have the option of selecting a saved template.

Templates can contain variables that will be replaced with the corresponding data in the address book's contacts at the time of sending.

Invoices and user data

Each user account includes a section detailing the user's personal information and billing details. This is the information that will be used to create the invoice(s).

At the beginning of each month we will upload your invoice, which you can view and download in PDF format at any time.
