About SMS Comparison Table and Site

What Is An SMS Gateway?

An SMS gateway allows a CRM, computer or e-mail to send and receive text messages through mobile network providers. The most common uses of an SMS Gateway are for bulk SMS and reminder services with an API allowing two-way communication with businesses or customers.

Applications of an SMS Gateway include:

  • Web SMS with contacts uploaded without software.
  • E-mail SMS integrating SMS with e-mail programs.
  • API SMS Services utilising CRM software.

Within the UK, text message gateways will be directly routed by telecommunication carriers to the major providers via premium or aggregator carriers. This will impact reliability, the speed and the prices of text messages sent.

It should be noted that a short message service (SMS) also known as a “text message” has a limit of 160 characters when sent to another device. This means that messages exceeding this character limit will be split into multiple parts which may lead to higher sending charges.

What British Regulation Should I Consider?

When sending any text message campaign within the UK, you must meet the Data Protection Act (2013).  The law states that no company can send legally unsolicited electronic messages. This Data Protection Addendum (DPA or “Addendum”) applies to the processing of Personal Data governed by the EU General Data Protection Regulation (GDPR) 2016/679 and, where so applicable, shall form part of the BulkSMS Standard Terms and Conditions (the “Standard Terms and Conditions”) to be entered into between BulkSMS and its clients (the “Client”) acting on its behalf and as agent for each Client Affiliate, with effect from the date set out.

This applies to text messages through a gateway with any message requiring:

  1. Consent – The receiver must have provided consent to receive text messages or be an existing customer who has an existing business relationship
  2. Identify – All text messages need to identify what business they came from
  3. Unsubscribe – There needs to be functionality to unsubscribe from future business SMS correspondence (2-way SMS). A company needs to ensure any such request is processed within five days.

From a compliance aspect, the SMS provider needs to feature a strong privacy policy, be SPAM compliant, have extensive terms and conditions and have a clear acceptable use policy. To learn more about direct marketing compliance you can view the UK direct marketing website created by the Commonwealth.

Tips For Sending Business SMS Messages

Research has shown that short text messages perform the best. 95% of texts will be read within 3 minutes of being sent and around 98% of mobile users are likely to have read the SMS by the end of the day.

While 160 characters can exist within a text message, short and sharp messages that don’t require scrolling receive optimal open rates and engagement. Try to only provide a single message, whether a greeting, reminder, offer or referral.

Mobile phone is personal so must understand an individual’s personal space. Unexpected bulk SMS messages can be intrusive so ensure they are functional and courteous but not too familiar. Customisation tools can help maximise relevance but there is always a line an advertiser shouldn’t cross. Also, understand when the recipient will receive the text and the reliability of the gateway. Nobody wants to receive a text at midnight!

Don’t over-use the bulk SMS marketing channel – Infrequent and brief messages from businesses will ensure that users don’t unsubscribe from the communication. Use other channels such as e-mails to regularly update e-mails but avoid text messages for such communications.

Make sure you have a legitimate reason to send SMS messages – Ensure every message passes on useful information, acts as a reminder or clarifies an arrangement. As long as it has a legitimate use to an individual they will be happy to receive more text messages in the future.

Using A Premium SMS Provider

If your business sends SMS messages to customers, clients, stakeholders or staff, then a premium direct gateway carrier is for you. Your message will be delivered directly to major text message service providers.

A text message gateway allows a computer to distribute or accept business SMS marketing transmissions to or from a telecommunications network. Most messages are usually routed to mobile phone networks. ClickSend is one such example of an SMS gateway provider using a direct carrier. SMS API Text Message Gateway

Need for a reliant premium SMS text message gateway provider when:

  • Time-reliant SMS.
  • SMS alerts.
  • SMS where content is highly private.
  • Return messages from your customers are highly important.
  • Marketing and communication campaigns.
  • Reminders for appointments and delivery of a particular service.

What is an SMPP Gateway?

An SMPP stands for a Short Message Peer-to-Peer Protocol. The SMPP gateway protocol is used within the telecommunication industry that exchanges SMS services between Short Messaging Entities (ESME) or Short Message Service Centers (SMSC). As a level-7 TCP/IP protocol, it ensures speedy SMS message delivery. The SMPP can receive and send messages from mobiles including CDMA, UTMTS, GMA and UMTS phones.

How Can A British Business Integrate An SMS API?

Utilizing an API is a common practice by British businesses that have large-scale text message requirements. Developers connect to the SMS gateway through their preferred API from SMPP, Java, .NET, PHP or SOAP. Most providers will support SDKs through sample costs, documents and reusable libraries. Make sure the provider you choose has support levels that match your understanding of an SMS API as you may need a hands-on provider.

When setting up your API, the British SMS provider will provide you with a sample code. This will allow you to connect to a SOAP API regardless of the SMS API language you prefer. A provider like MessageMedia has samples o Java, GitHub in C3, Bash & Python as well as PHP. Other languages such as C++, Ruby and Powershell can also be utilised. Just talk to their support team when you first join and talk to their specialist SMS API technical support software person.

What Are The Benefits Of An SMS API Integration To A Text Message Platform?

API integration is so popular because:

  • Two-Way Messaging: The ability to send messages to the major British SMS networks and receive replies from the users.  
  • Message Tagging: A two-way SMS feature that reports on the exact application that an outbound message reply corresponds to.
  • Delivery Reporting: Track your text messages’ exact time they are received to handsets providing you with a full delivery audit trail.
  • Validity Period: Specify just how long a text message should be valid so that after this time if the SMS has not been delivered it doesn’t get delivered.
  • API Web Push: Get real-time delivery of inbound text messages to a URL for quick replies from staff, customers unlike polling can take time to validate

SMS Gateway Frequently Asked Questions

API SMS Gateway

An API (Application Programming Interface) is a sophisticated software intermediary that allows two applications to talk to each other. It simply allows query parameters via URLs that provide SMS gateway instructions to send text messages. This can be enabled through scripting languages such as PHP that can be integrated to web forms and other applications.

How does SMS work?

SMS is abbreviated for Short Message Service. It’s a communication method that allows a mobile phone to communicate with each other. An SMS gateway allows computers and e-mail to also send and receive text messages making it suitable for businesses.

How does the SMS gateway work?

A text message gateway acts as a relay. It translates from one protocol to another through SMSCs (SMS centres). These SMS centres include wireless networks that handle forwarding, routing and stores and other SMS operations ensuring the messages are delivered to the destination mobile phone.

SMS integration is when businesses use their existing database or CRM to target their customers through an SMS Gateway. This can include targeting customers with promotions, news and other information. This integration can use automation to communicate with customers at various forms of the consumption life cycle.

SMS means short message service while MMS means Multimedia Messaging Service. This is the next level of a text message allowing video, audio and picture content to be sent to a mobile device. Sending an MMS can lead to a premium price depending on the SMS gateway used.

E-mail security gateways have gained popularity as they monitor the e-mails that are processed to be sent to mobile devices. They can assist in preventing unwanted content from being delivered that can be caused by phishing attacks, SPAM and malware.

This depends on the regulation of the country you operate in and your provider. Most countries require providers to have an opt-out functionality and ways to contact the SMS sender. This is the case with the UK. Ensure you meet these requirements to remain compliant.
