In a world where communication methods are changing at an ever-growing
pace, SMS has proven a fast and reliable way to deliver information to anyone
anywhere for fifteen years. In the last few year a raft of applications
harnessing the strength of this simple yet powerful messaging protocol have
proliferated. To accompany this growth, the range of SMS providers offering a
range of commercial applications for this simple and ubiquitous messaging
application, has also grown. Because of this, choosing an SMS provider has
become an increasingly complex task due to the multitude of fiercely
competing offerings, all claiming to be uniquely the best in the market.
In this guide, we aim to make this task more manageable by offering you a set
of questions to ask yourself when choosing an SMS provider. After defining
what types of SMS providers exist in the market, we will proceed to cover
the most important factors that should be considered when selecting one,
looking at factors such as coverage, quality of service, backup routes,
customer service, among others.
An SMS service
provider is a company which provides SMS messaging services, but is not in
itself a mobile network operator (MNO). In terms of performance, cost and
messaging services, SMS service providers belong to two different models: SS7
connectivity and aggregators.
An SS7 connectivity provider centres on
strategic partnerships with mobile network operators, supplying the SMS
service provider with direct access into the deep level mobile telecoms
infrastructure. This solution allows SS7- based service providers the ability
to route data through their own infrastructure, allowing SMS sending directly
to and from recipients without having to go through the SMS-Centres of other
operators. Consequently, SS7 connectivity provides reliability, speed and
An aggregator sets up multiple agreements with operators to send
and receive data into and out of their SMS-Centre, but don’t have any direct
connection into the deep level mobile telecoms infrastructure (SS7).
Aggregators can only guarantee the delivery of the message until it reaches
the operator’s SMS-Centre - after which it is out of the service provider’s
control. On the flipside, aggregators are often able to offer greater
coverage, options for different pricing and quality levels and overall
- Does your potential SMS provider have good
Network coverage is an important factor to be considered, since the
provider might not be able to send messages to the network you are trying to
reach. A list of supported mobile operators is usually provided on the website
of the messaging provider or if not, can be acquired upon request.
be noted however that SMS aggregators may be unable to guarantee that a message
you send will definitely arrive at your destination operator, even if the
network is on their coverage list. The reason for this is that an SMS message
may be routed to other gateways not directly controlled by your SMS provider.
This problem should not occur with SS7 connectivity providers, as they only
include in their coverage list mobile operators they can directly reach without
resorting to routing messages through third parties. However, the downside is
that due to this stricter policy, messaging operators might suffer from limited
network coverage when compared to standard providers.
In addition, it should
also be noted that problems with SMS routing might occur if the destination
mobile number has been ported to a network which your messaging provider or
operator cannot reach.
- How high is the SMS provider's network quality?
Some SMS providers
offer very cheap prices per message, but they may be highly unreliable. The SMS
may never reach the destination mobile, or may do so after a considerable delay.
It is therefore prudent to always test the service offered to you by the SMS
provider. Usually this can be done by setting up a test account which allows a
limited number of free messages to check network and service quality.
Standard SMS aggregators often offer several message routing options. SMS
messages can be routed through more reliable but more expensive networks, or can
alternatively opt for less reliable but cheaper networks. Since the higher
quality routes offered by aggregators are often SS7 routes, and SS7 connectivity
providers only use those routes, messaging operators offer universally high
quality routes without the option of downgrading quality and reliability.
Messaging operators are therefore, a more prudent choice for people who value
reliability and quality over price.
- Is the protocol / interface you
intend to use supported by the SMS provider?
Protocols / interfaces
commonly supported by SMS providers for sending and receiving SMS messages
- HTTP. That is the most commonly supported protocol for sending and
receiving SMS messages. It is quite simple to use.
- HTTPS (HTTP + SSL
encryption). Data transmitted over HTTP is not secure and can be monitored over
the Internet by other parties, since it is transmitted in clear text. If you do
not want your data to be readable to others on the Internet, you should use
HTTPS instead. With HTTPS, data is encrypted before bring transmitted over the
Internet, thus protecting it from eavesdropping.
- XML over HTTP / HTTPS. One
or more SMS messages are put in an XML file and uploaded to the SMS provider's
server. XML over HTTP / HTTPS is superior to HTTP / HTTPS for bulk SMS sending
since it makes possible the submission of a large amount of SMS messages in a
single HTTP request.
- SMTP (email to SMS / SMS to email). Enables sending
and receiving SMS messages in the form of email.
- SMPP. The SMPP protocol is
usually used by advanced users. It is a binary protocol for communicating with SMSCs (SMS centers) and SMS gateways. SMPP is suitable for sending and receiving
huge amounts of messages.
An SMS provider usually supports only some of those
protocols / interfaces. It is important therefore to make sure that your SMS
provider supports the interface you would like to use.
- Does the SMS provider provide any option of testing their service?
Needless to say, testing the service of the SMS provider before signing a
contract is highly advisable. As previously mentioned, it is possible that your
chosen SMS provider cannot send messages to, or receive messages from, your
destination mobile operators so this must be tested. You should also test the
SMS provider's network quality to ensure it matches your requirements and
As mentioned earlier, many SMS providers offer a number of
free messages for the explicit purpose of testing out their services. The number
of messages offered might be fixed or flexible, but is generally enough to check
the quality, reliability and network coverage of your chosen provider
- Does the SMS provider have backup routes for your key destination networks?
While common knowledge might suggest that one route to a destination network
is enough and all else is just redundancy, this is not always true. Some
problems might occur that can temporarily, or even permanently, make the primary
routes unavailable. For example, these can be blocked by the destination
operator, be overloaded due to very high traffic, or in case they are provided
by third party providers in the aggregator model, become unavailable due to
network outage. Therefore, it is paramount to ensure that your SMS provider is
able to provide redundancy in the form of backup routes for primary destination
- Is receiving of SMS messages or 2-way SMS required by your SMS
The simplest type of SMS messaging service is the 1-way,
also known as mobile terminated (SMS-MT SMS sending). Any SMS provider offers
this service. There are other services, for example mobile originated SMS
(SMS-MO also called SMS receiving) which allow reception of SMS sent by mobile
numbers within the network coverage of your SMS provider. The two can be
combined to offer a 2-way messaging service which enables both sending and
receiving of SMS messages. SMS-MO and 2-way messaging are technically more
challenging and therefore not provided by all SMS providers. It is important to
clarify what type of SMS messaging you will need for your application and make
sure your chosen provider offers the services required.
- Do you prefer
short codes or long numbers to receive messages?
In case your
application demands the receiving of messages, you might also need a mobile
number to which those messages can be sent. Many SMS providers are also able to
offer you such numbers, but there are two different types – short codes and long
Short codes (e.g. 60777) are special telephone numbers,
significantly shorter than a full telephone number, which can also be used to
address SMS from mobile phones or landlines. These can be from four to eight
digits long, depending on the country regulations and are only usable within the
country. They are also significantly easier to remember, due to their shorter
size. Additionally, SMS sent to such numbers can be billed at premium rates.
Since the same number can be shared among several companies or brands, messages
sent to this number should always be prefixed with the correct word. For
example, if you are a real estate agency and have a short code on which people
can send queries about prices of property, the format for the SMS you defined
might be the word PRICE followed by the property number. If the potential
customer omits or misspells the word PRICE, their message will never be
correctly routed to you.
Long numbers (e.g. +44 7624 80055) are an
alternative to short codes and can be used as an SMS and voice reception
mechanism by businesses. While they are more difficult to remember, since the
standard length of a long number is about eleven digits, they are
internationally available and allow businesses to have their own number.
Messages sent to long numbers are not billed at premium rates.
between long numbers and short codes is very much a decision to be made
depending on the demands of your application. It is vital to make sure your
chosen SMS provider can offer your preferred solution.
- Can the SMS
provider supply delivery receipts for all SMS messages?
(DLRs) are return messages designed to confirm the delivery of each message to
the destination mobile number. There are practically two types of delivery
receipts – sourced from the mobile network operator’s SMS-C and sourced directly
from the mobile phone.
In the case of the operator sourced DLR, the delivery
receipt does not actually confirm the delivery of the message to the destination
mobile phone, just to the destination mobile operator network. The disadvantage
of this is there is no guarantee that this message has been delivered to the end
In the case of mobile-sourced DLRs, it is the destination handset
itself which acknowledges the delivery of the message. Such a delivery receipt
provides an absolute guarantee that the SMS has reached its destination.
delivery receipt is preferable to no delivery receipt whatsoever, since both
provide at least some guarantee of the successful routing of the message. All
delivery receipts are provided by your SMS provider, providing a degree of
certainty that the SMS has reached its intended destination.
- Do you need
to know the reason for a failed delivery of the SMS message?
successful delivery of the message is always the intended goal delivery can
potentially fail for reasons beyond the control of your SMS provider. In such
cases, it can be very helpful to know the reasons for these failures and some
SMS providers offer GSM return codes which give notification of the reason for
the failure. Examples of these include the fact that a phone might be switched
off, be out of network coverage or even have a full inbox.
In any case,
knowing the reasons for failed message delivery is important, so GSM return
codes can be a useful tool.
- How good is the platform throughput of
your SMS provider?
SMS has three main advantages as a communications
medium – it is fast, ubiquitous and easy to use. But whether it is as fast as
promised can depend on many things, one of which is the capacity of the platform
of your SMS provider. Simply put, this means how many messages per second can
the platform of your SMS provider handle without delays and traffic congestion.
Anyone sending bulk SMS should ensure that the SMS-C being used is capable of
handling the volume you desire. Similarly, time-sensitive messages such as
one-time passwords, meeting alerts or emergency notifications, depend on the
ability of the platform to handle the traffic fast and reliably.
the throughput of the platform of your chosen SMS provider is up to your
standards by comparing it to competing offerings and also if possible testing
the service during peak times. Another way of doing this is to get a guarantee
to the throughput of the platform via a service level agreement, explained in
the next point.
- How can an SMS provider guarantee quality of its service?
Not every aspect of the performance of a platform can be tested
within the limited amount of testing messages that an SMS provider will offer
you. It is therefore important to demand a level of commitment to quality and
performance from your chosen SMS provider, before signing a binding agreement.
This is commonly done in the form of a legally binding service level agreement
(SLA). The SLA provides a pre-agreed level of services, priorities,
responsibilities, guarantees and warranties.
If quality and reliability of
your application is a concern to you, then it is important to ensure a level of
commitment to all manners and aspects of overall performance from your chosen
SMS provider. Having a service level agreement included in the contract with
your SMS provider is an ideal way to get the needed commitment.
- How good
is the SMS provider's customer service?
A good SMS provider should have a
customer service team with a complete understanding of its system. The team
members should be able to answer and tackle all sorts of questions and problems,
be patient and thorough in answering inquiries and have fast response times. The
quality of customer service is a reflection of the company's quality and the
importance it places in this aspect. To find out if SMS provider’s customer
service is up to your expectations a good way is to email a few questions to
them while testing the service. Here are a few things to consider:
• Do they
have a 24/7/365 technical support?
• Do they offer a hotline number to report
• Do they have proper technical documentation that shows you
how to connect to their platform?
• Do they offer an online self-service
Most SMS providers provide customer service by email. If you
require customer support over the phone, make sure your provider has this
option. You can test their responsiveness and helpfulness similarly to the
email test by calling them up and asking a few questions while testing the
