Bulk SMS

Bulk SMS Icon Illustration

Bulk SMS refers to the sending of a large number of SMS messages to a broad audience simultaneously. It’s commonly used by businesses and organizations for marketing, alerts, reminders, and notifications.

The pricing for bulk SMS depends on the location of the traffic, country regulations and restrictions, and numerous other factors. 

  • The cost per SMS in the SMS credit bundle purchased.
  • The country or countries the SMS messages are being sent to.
  • The route you use to send your SMS messages.

We work on a prepaid basis. Should you prefer to request a quotation to purchase before making payment, please email requesting a quotation, please include your company, account number and the number of credits you would like to purchase.

You do not pay for replies to the SMS messages you send out. The cost of replying to an SMS message is borne by the recipient, not the sender.

No, our SMS credits do not expire – your SMS credits will be available in your account for as long as you need them.

Yes, delivery reports are available and will indicate the status of sent messages e.g. Submitted, Delivered, Expired, Failed etc

You can schedule your SMS messages to be sent for any future date, for up to 3 months in advance.

A typical SMS message is only 160 characters long, but we do allow you to send up to 3 SMS messages in one send. 

The message gets split into three parts (concatenated) when you send it, but when it arrives at the recipient’s phone it will appear as a single SMS message. This means you can send a message of up to 459 characters.

Yes, you can set this up on your Channel Mobile account.


WhatsApp Business API Updates for Better Customer Engagement

WhatsApp Business API is different from the free-to-download WhatsApp Business App. The free WhatsApp Business App is built with the small business owner in mind. 

Channel mobile offers the WhatsApp Business API platform – which enables businesses to build communication experiences to support their business goals. Create customised messaging experiences on WhatsApp with the WhatsApp Business Platform Cloud API hosted by Meta and connect with customers in a simple, secure, and reliable way. Businesses using the WhatsApp Business platform can connect thousands of agents and bots to interact with their customers programmatically. In addition, the APIs can be integrated with numerous backend systems, such as CRM and marketing platforms.

The WhatsApp Business API, also known as the WhatsApp Business Platform, is for larger businesses and independent software vendors looking to integrate WhatsApp messaging into their own products. It is designed to manage much larger conversation volumes.

WhatsApp Business API is more powerful than WhatsApp Business App as it allows you to:

  • Broadcast to Unlimited opted-in users
  • Use WhatsApp Business on Multiple Devices
  • Automate Notifications
  • Install WhatsApp Chatbots
  • Send Messages with clickable buttons

You can port your phone number to Channel Mobile – please fill out the contact sales form, we will contact you and discuss the migration.

It takes at around two weeks for WhatsApp to approve a business for using WhatsApp Business, if all the correct information is provided. Information needed to set up WhatsApp API:

  • Verified Facebook Business Manager ID
  • Telephone Number
  • Display Name and details

As part of the application process for a WhatsApp Business Account, a Facebook Business Manager ID is required. Without it, WhatsApp will not approve your Business Account application. As your WhatsApp Business Solution provider, we will manage all the necessary admin and paperwork.

Our WhatsApp Business API prices are tailor made to your individual business needs. Please contact our WhatsApp Business API experts and get started with a tailor-made offer.

Before you can start using WhatsApp for business communication, you must first go through WhatsApp’s official approval process where the WhatsApp team will review your request according to their Business Policy and Commerce Policy. As your WhatsApp Business Solution provider, we will handle all the necessary admin and paperwork.

Data privacy is a crucial topic in customer communication, and the WhatsApp Business API’s secure setup enables companies to use WhatsApp in customer communication. Messages are end-to-end encrypted, which means WhatsApp or other third-party providers cannot read them – making this solution more secure than a conventional email.

Unlike WhatsApp Messenger, which is built for personal communications, the WhatsApp Business API Platform is designed for external business communications. 

Our On-Premise API is hosted on secure global data storage centres; these servers are POPIA/GDPR-compliant.

USSD Codes

No data is needed. USSD codes work across all cellular networks – customers just need a connection to the GSM network. No internet connection is required, as USSD works on voice connectivity.

  • Standard-billed USSD strings: where the end-user’s mobile handset is charged directly.
  • Reverse-billed USSD strings: where you the client are charged based on the session length.

NB: Network Operators can have different session lengths and maximum duration, but they typically charge for every 20 seconds of the session.

Yes, you can add additional service code extensions or sub-codes as you require free of charge.

USSD allows for a maximum of 182 characters. However, we recommend that you remain within a 160-character boundary due to differences in the maximum number of characters accepted by the different Network Operators.
