I am looking to build an IM app using the Sinch SDK, but wanted to know what the max number of characters that I can send in a message is? Can't see that in the documentation.
There isn’t a fixed limit to how many characters can be included in a message. Messages will be split into multiple if size is too large, however we discourage from sending very large messages such as encoding images into headers…

I am consuming message from IBM MQ queue. Messages are of format MQSTR. But message data is TEXT+Binary. This Binary data is nothing but a JPG image
When these messages are consumed by my JMS consumer, I can see some encoding issue for Binary data, due to which transformed image is distorted from original.
I have tried every possible aspect (different IBM specification). But was not able to make through.
If someone already faced such issue please suggest possible solution for it.
If the message has an MQSTR MQMD.Format, then it must be a text string. MQ will convert text strings between codepages when required (eg ASCII to Unicode). If the message is not meant to be a string - which it sounds like from your limited description - then whoever creates the message needs to set the format suitably, and the receiving app must be prepared to parse and convert the message body components.
I am creating a message to send to user from bot. The type is data and size is at about 1mb. When I am using bot emulator the message works, but when I publish my bot the message doesn't work. The Badrequest error is returned.
My question is: Is it possible to send messages over 300kb from bot to user?
Thank you so much for your attention.
There is no set size limit within the bot framework itself as this is dependent on the channels. You will have to refer to the respective channel API documentation to know about the message size limits.
The documentation on message length for Microsoft Teams can be found here.
For the Direct Line channel, he total size of the activity, when serialized to JSON, must not exceed 300K characters.The file size limit or the attachment limit is 4MB.
For Facebook Messenger,the text message must be UTF-8 and has a 2000 character limit.
I'd like to count the messages of a specific conversation in Telegram. There should be a way using Telegram Desktop and using the debugmode to save the log information (see https://telegram.wiki/desktop/tdesktopcountingmessages). Unfortunately the count-tag is missing in most cases. Any other ideas?
The easiest way to do this currently is by searching for '+' in the conversation of interest. This will retrieve all messages and you can see the count from the search results. See attached image for an example. This conversation contains 32 messages in total.
Twilio limits long code SMS to 1/sec. To improve my throughput, I split my batch into 5 phone numbers. I've found each HTTP POST to the Twilio API takes about 0.5 seconds.
One would think using 5 twilio phone numbers to send a message to 1000 cell phones would take 200 seconds, but it will take 500 seconds just to POST the requests. So two phone numbers will double my throughput, but more would not make a difference.
Am I missing something? I was thinking it would be nice if the API would take a list of phone numbers for the "To" parameter. I don't want to pay for a short code, but even if I do it seems the maximum throughput is 2/sec unless you resort to the complexity of having multiple threads feeding Twilio.
I've noticed TwiML during a call let's you include multiple sms nodes when constructing a response so it seems like there should be a way to do the same for outbound SMS.
Twilio Evangelist here. At the moment, we require that you submit each outgoing SMS message as its own API request.
The current rate limit on a longcode is 1 message per second. If more messages per second are sent, Twilio queues them up and sends them out at a rate of 1 per second.
A potential workaround is to make async requests across multiple phone numbers. This can be accomplished with the twilio node.js module or an evented framework such as EventMachine for Ruby or a similar toolset for your language of choice.
Hope this helps!
Here's a more modern answer. Twilio now supports Messaging Services. It basically lets you create a service that can group multiple outbound phone numbers together. So, when you fire off requests for a text to be sent, it can use ALL the numbers in the message group to perform the sending. This effectively overcomes the 1 text per second limit.
Messaging services also comes with Copilot. It adds several features such as "sticky sender". This ensures the same end user always gets texts from the same number in the pool instead of getting a text from different numbers.
If you are using the trial account, even looping with a 5s timeout between each item in the array did not work for me. And that was for just two numbers. Once I upgraded the account the code worked immediately without needing a timeout.
You know it's the trial account if the SMS you receive (when sending to only one number) says "Sent from your Twilio trial account - ".
Suppose that several machines are interacting together using python's zeroMQ client.
These messages are naturally formatted as strings.
Is there a limit to the length of a message (string)?
There is no limit to the size of messages being sent however small messages are handled differently than large messages (see here).
The max size of a small messages is defined in the source code at 30 bytes (see here, look for ZMQ_MAX_VSM_SIZE).
There is the socket option ZMQ_MAXMSGSIZE which causes a peer sending an oversized message to be disconnected, but the default is "no limit".
No limit
As for small size messages transmitted within zmq_msg_t structures, their limit is 29 bytes (for zmq version 3.2.2)
"max_vsm_size = 29," quoted from https://github.com/zeromq/libzmq/blob/master/src/msg.hpp
Some socket types support up to 2^64, but some less than 2^31.
You should build a protocol that keeps chunks below that size anyway, but this is the real answer.
