You are allowed to bind as a transmitter, receiver or a transceiver. To receive delivery reports, you must bind as a transceiver or a receiver. Delivery reports will be sent equally over all of your currently available sessions capable of receiving them transceiver or receiver. By default, you are allowed to bind with 4 sessions. There is no other throughput TPS limitations besides internet speed. Scheduled delivery is supported over the SMPP protocol using relative time format.
For example, that would would mean that the message will be delivered in 7 years, 6 months, 5 days, 4 hours, 3 minutes, 2 seconds and 1 tenth of a second from now. Each request to our system will receive an acknowledgement as per SMPP v 3. Most relevant command statuses, including Infobip-specific ones, are in the table below:.
GSM error codes are returned in DLRs and explain the status of the message whether intermediate or final. Possible error codes. Infobip system will automatically convert your message into a Flash notification using the message parameters you have submitted. Once the Number Lookup request has been finalized on the Infobip system, you will receive DeliverSM PDUcontaining the short message with: IMSI for the required destAddress or an error code in case of failure, plus additional optional info fieldsdepending on your package.

Price per message multiplied by for compatibility reasons.This article is not a substitute for this specification: it gives practical tips on how to interpret the protocol specification and match it with the Wireshark display in order to help troubleshoot problems between Adobe Campaign and the SMS-C partner.
Since the SMPP protocol contains many different parts left to the interpretation of the implementation team, there are differences between different SMS-C. When troubleshooting problems, always contact the SMS-C partner to obtain information or to help you double-check what you get. If you are using an SMPP simulator instead of connecting to a real SMS-C, you should use the source code or a debugger to understand what is happening.
If you don't have direct access to the machine, it may be necessary to capture using command-line tools like tcpdump. If you already know the TCP port of the connection, put the correct filter to avoid capturing all traffic. Here is a sample tcpdump command-line to capture port to outfile.
This topic assumes that you're familiar with the basics of Wireshark: capturing packets, defining simple filters, reading packet details. To isolate packets by phone number or by text content, use the search feature with the following settings:. The protocol works over TCP and is fully binary, meaning that special tools like Wireshark or a hexadecimal editor is required to decrypt the content of the stream.
Short Message Peer-to-Peer
Wireshark will reassemble PDUs correctly, so it is mostly transparent for the Wireshark user. Note: The list of standard commands can be found in section 5. There is a timeout for responses, it is typically 10, 30, or 60 seconds.
Most of the time, these responses are immediate and a response timeout is not reached. Make sure to distinguish between SMPP response errors and SR error codes: the same error code may mean different things in the response error or in the SR error field. When reporting an error code, you must be very careful about where you found it, because the meaning of the value depends on its context.
These operations are described in section 4. Note that the TCP connection is always initiated by Campaign, even for the receiver mode.
This cannot be controlled because of the way the connector is designed. To send an MT, the transmitter must be successfully bound. Before anything else, check that the bind process has been carried out successfully. Caution: SMS encoding is a complex subject with many traps and various implementations. Good practice is always contact the SMS-C partner in case of encoding problems.

When you send a text message from your cell to your friend's cell, it's being routed via the SMPP protocol. These messages go through the carriers' cell networks, as compared to the carriers' email network called SMTP. SMPP is the preferred method as it has priority routing and tends to be delivered at a quicker rate. Messages sent over SMPP are routed directly to and from the wireless service provider over a secure private network.
Most major wireless service providers can provide confirmation of message delivery. The greatest benefit to SMPP is the fact that messages are two-way, enabling mobile phone subscribers to respond to the messages you send them. SMPP also supports the ability to schedule the message delivery date and time among other functions.

When a message is longer than these limits, then a "long SMS" or concatenated SMS can be sent that uses segmentation and reassembly SAR to split the long message into multiple SMS message parts that use meta data to associate the parts.
SMS can also carry non-text message payloads up to x 8-bits in a single message. The SMSC then attempts delivery of the message to the destination mobile, which may be on the same network or another interconnected mobile network. There are a number of free services available online for use in SMS testing.

The SMPP protocol specifications are still available through the website which also carries a notice stating that it will be taken down at the end of July 31, - The SMS Forum, a non-profit organization with a mission to develop, foster and promote SMS short message service to the benefit of the global wireless industry will disband by July 27, A press release, attached to the news, also warns that site will be suspended soon.
In spite of this, the site is still mostly functioning and specifications can still be downloaded as of 31 January Contrary to its name, the SMPP uses the client-server model of operation.
Before exchanging any messages, a bind command must be sent and acknowledged. Message exchange may be synchronous, where each peer waits for a response for each PDU being sent, or asynchronous, where multiple requests can be issued without waiting and acknowledged in a skew order by the other peer; the number of unacknowledged requests is called a window ; for the best performance both communicating sides must be configured with the same window size.
They start with a header which may be followed by a body:. The data is shown in Hex octet values as a single dump and followed by a header and body break-down of that PDU. The value break-downs are shown with decimal in parentheses and Hex values after that.
Where you see one or several hex octets appended, this is because the given field size uses 1 or more octets encoding. SMPP 3. Other values in the range are reserved in SMPP 3. Unfortunately, unlike SMPP 3. According to SMPP 3. Which encoding it really is, depends on the type of the SMSC and its configuration. The original intention of error scenarios was that no body would be returned in the PDU response. When SMPP 3.
What should have been done was to add the clarification that we eventually added in V5. The recommendation I would make to vendors. The reason you may need this ability to include what I call dummy bodies with NACKed requests is that the other side of the equation may be unable or unwilling to change their implementation to tolerate the missing body.
The only way to pass delivery receipts in SMPP 3. While SMPP 3. This splits SMPP implementations to 2 groups:. It should use a minimal set of features which are necessary to accomplish a task. And if the goal is communication and not quibbling, each implementation should overcome minor nonconformities with standard:. The SMPP protocol is designed on a clear-text binary protocol which needs to be considered if using for potentially sensitive information such as one-time passwords via SMS.
