SMS Gateway Technology
What is an SMS Gateway
An SMS gateway is a software that allows you to send and receive SMS messages from your applications. It can also be used to provide SMS services. An SMS gateway is often referred to as an SMS Server. It is a self hosted SMS gateway. You may install an SMS Gateway on an Android phone or on a Windows or Linux computer. Ozeki 10 SMS Gateway is an outstanding SMS Gateway software with several unmatched advantages.
An SMS gateway is ideal for lots of simple to complex scenarios. Some of which are:
- Provide SMS service to customers
- Act as a centeral hub for SMS services
- Provide SMS service for SMS applications
- Provide SMS aggregator service
- SMS routing
- Use as a reporting gateway to keep track of all SMS messages
- Use as a protocol converter
- Forward SMS messages to mobile networks and 3rd party SMS service providers
What is the best SMS Gateway in 2023
In 2023 the best SMS gateway for a company is either an Android SMS Gateway installed on a high-end mobile phone, or a self hosted SMS gateway installed on a Windows computer or an SMS gateway installed on a Linux server. The first option of running an SMS gateway on an Android mobile is best if the number of SMS messages stays below a few thousand SMS per day or if the SMS service is still in pilot or development phase. The second option of self hosting an SMS gateway is recommended if you consider to build an important communication infrastructure for your business. Self hosting can be done in virtual server hosting facilities, such as Amazon Web Services or Microsoft Azure Cloud, or it can be hosted in your own server room if data security and operational reliability is crucial.
What are the benefits of a self hosted SMS Gateway in 2023
Operational reliability: With a self hosted SMS gateway system, you can connect to multiple SMS services over the Internet, and you may even connect to the mobile network wirelessly. You can setup backup servers and backup SMS routes to avoid a single point of failure. The possibility of intervention, monitoring and alerting capabilities is also a huge plus and it allows you to increase the operational reliability of your SMS infrastructure. We should also mention the possibility of automated backup and easy restore options when you have your SMS infrastructure in your own hands.
Service provider independence: It is beneficial to be independent of a single SMS service provider. It gives you freedom in terms of negotiating business conditions and prices if you know you can easily switch providers without the need to rewrite your software. It is also great to be able to send SMS messages through different networks and to do least cost SMS routing, load balancing and fail over routing. If you write your code to an Ozeki API, for example using the Ozeki C# SMS API, you can be sure that you will always have a chance to switch to another SMPP SMS service provider or you can take advantage of a new player's offerings by simply configuring their service in the Ozeki HTTP/REST SMS client connection.
Data security: One of the most important aspects of operating content services and marketing businesses is to be able to keep your contact list and data safe. If you want to make sure that nobody else has access to the phone numbers of your valuable client list, it is a good idea to operate your own SMS gateway. This way you don't have to upload your contact list to an unknown third party, who can sell or use your contact list. It is also much easier to comply with EU GDPR regulations if your data is residing on your own servers.
Operational costs: With your own SMS gateway cost optimization can be done using least cost routing and relying on SMS credit limit management offered by Ozeki SMS gateway. Since you can connect to multiple networks you are in a better position to negotiable tariffs and to take advantage of bulk message buying offered by provider for certain destinations. In most cases when you connect to mobile network's short message service centers (SMSC) directly you will not be charged for incoming SMS messages.
International business: If you operate an International business, or you plan to expand Internationally, it is important for you to be able to connect to local mobile network operators from your centeral IT data center over the Internet. Local mobile network operators can give you better terms and conditions then International SMS service providers. Since they often operate their own mobile network you can expect better delivery times, better reliability and compliance with local legal regulations. Your local SMS messages will not be rejected as international spam and have a higher priority in delivery over International SMS. If you connect Ozeki SMS Gateway to local national networks, you will have access to local phone numbering schemes and local short codes. You won't have to use the international country code prefix to send and receive SMS in those remote networks.
Better reporting: Ozeki SMS gateway can be configured to log every SMS into a database. It can use Microsoft SQL Server, MySQL, Oracle or virtually any other SQL database system to provide you with a log of all your SMS traffic. You will have information about when a message was sent by who, through which network at what cost, and you will know that message submission and delivery timestamps, status codes and error messages. Most important of all incoming SMS delivery reports are also matched to each submitted SMS, to let you know whether an SMS as delivered or not successfully to the recipient handset and when did the recipient receive the SMS.
Higher performance: There are to key aspects of SMS system performance. One is to have an in memory operation, that gives you outstanding computing speeds. The other is to have a load balancing system, that is able to distribute the load between multiple mobile network and multiple SMS service provider connections. Ozeki SMS Gateway provides both of these elements. It can reach delivery speeds of up to 1000 SMS per second per server computer thanks to it's in memory computing approach, and it can distribute SMS traffic among connection for both incoming and outgoing links.
SMS gateway performance
SMS gateway performance matters. One of the most common business mistakes we have seen was seening businesses making a small initial investment in their SMS infrastructure instead of investing into a high performance SMS gateway system in the beginning. This mistake became very costly later.
If your business grows, your SMS volume will grow. The number of software you build, that send and receive SMS messages will grow, and sooner or later you will send SMS marketing campaigns, one time passwords, notifications, alerts and other SMS content. Eventually your SMS traffic can reach a point when an SMS service provider might not be able to keep up with your demands. This is when it will start to become very costly if you cannot add a second or third provider without rewriting your codes and when you won't be able to switch to load balancing, backup routing, and to clustered redundant infrastructure. (Note that Ozeki SMS gateway offers these options.)
This statement might sound absurd to you now, but without a high performance SMS gateway infrastructure it is dangerous to use SMS in your business. Here at Ozeki we have met many cases where SMS aggregators, and on-line SMS service providers using their own custom made platforms could not keep up with growing SMS volume. We have experienced unacceptable delays, lost messages, delivery reports mixed up, messages dropped to name a few events. (And we are not talking about "no name" small providers. Think about NYSE listed and highly advertised services.) Serving lots of messages at a steady rate is demanding, and many providers are not up to the challenge. Ozeki SMS Gateway is currently one of the (or probably is the) highest performance platforms out there. Check out it's performance demonstrated in a speed test delivering 1 000 000 messages.
Running an SMS gateway on an physical server
Operate your SMS server on a phycisal compuer is beneficial because it gives you full control over the hardware and software aspects. This option gives you the highest possible performance. You get direct access to the memory, the CPU, the hard disk and the network resources, and all the processing of multi-threading CPUs are there to serve your SMS infrastructure. Ozeki 10 SMS gateway thrives when it is running in a multi-core multi-thread rich environment. It will give you unbeatable performance.
The drawbacks to using a physical server is that hardware upgrades are difficult, because you have to reinstall configure everything. Backing up and restoring a virtual machine is much more straightforward.
Runing the sms gateway on a virtual machine
Although an SMS gateway performs better on a real server, there are numerous benefits to using a virtual machine (often referred to as Virtual Private Server or VPS). Many users vote for this possibility when they use an SMS gateway. Maybe the biggest incentive to using a virtual machine is that it can be hosted in a server hosting facility. Amazon AWS, IBM cloud hosting and Microsoft Azure are popular choices among the companies we work with. If the SMS gateway is hosted at such a company, you don't have to take care of hardware issues.
If you operate your own virtual machine environment, you will like the fact that this technology allows easier managmenet of backups and restores. It is also great that running multiple virtual machines on a single physical server can save money. A weak point to using a virtual machine is that direct access to hardware resources become difficult. For example if you want to attach a GSM modem through an USB cable, you might have a hard time assigning the physical USB port to the appropriate virtual machine. If you run the SMS gateway on a virtual environment make sure you assign sufficient virtual hardware resources to the system. This is neccessary, because you want to make sure, that you don't miss out on performance. Also make sure that the virtual network for the smpp gateway is set up properly.
While talking about virtual machines, we must tell, that Ozeki 10 SMS gateway is known to work reliably in the following virtual environments: Windows Virtual PC, Microsoft Hyper-V, Solarwinds Virtualization Manager, Parallels Desktop, VMware Workstation Player, Citrix Hypervisor, QEMU, Xen Project.
Running an SMS gateway on an Android Mobile
If the SMS volume your business requires is below 10 000 SMS per day, an Android mobile phone might be the option you need. An Android phone has one or two SIM cards and will provide you the means to send and receive SMS messages instantly. It can run the same Ozeki SMS Gateway software that you can install on Windows or Linux, and will provide all the API'S and connection options, that are provided by a desktop or server based SMS gateway system.
One advantage to using an Android SMS Gateway comes from the SMS tariffs included in mobile phone subscription plans. The SMS tariffs are often very convincing, because many mobile network operators advertise unlimited SMS messages free of charge. If you run your SMS gateway on an Android phone you can take advantage of such offerings, and you can send SMS messages from your desktop and business applications free of charge.
There are three scenarios when you should definitely consider and Android SMS Gateway: First, when you want to try, test and evaluate an SMS solution. Second, if you don't intend to send or receive more then 10 000 SMS messages per day. Third, if you already operate a PC based SMS gateway system and you would like to give an identical platform with SMS capability to developers for testing.
Other scenarios might also make an Android SMS Gateway a viable choice: If you need access to a particular mobile network through a local phone number, you may setup a local Android Mobile phone connected to that network wirelessly, and you may connect to the Android mobile through SMPP and use it as a local SMS service provider.
You may use several Android mobile phones to provide you a pool of telephone numbers. Each Android mobile phone comes with one or two SIM cards, so each can give you one or two local phone numbers to use for SMS messaging. These Android phones can be connected to a centeral SMS gateway through the SMPP protocol or the OZX protocol and can give you a powerful service that can offer several phone numbers for communication. Having access to many mobile phone numbers is an advantage if you wish to isolate the traffic of certain users and applications. You can assign an individual phone number to each user or application.
Finally we should mention that the built in battery of an Android phone is also an advantage. Even if the power goes down, your SMS gateway will operate. It can send SMS alerts about the power outage itself, It can notify you in an SMS if your webserver goes down or it can send you an SMS if your E-mail server is not accessible because the UPS battery is drained. It can come very handy to be able to notify relevant people automatically in critical no power scenarios.
