My Twilio number is not enabled to send sms. How can I enable my twilio number to send sms?
It is showing "Messaging is unavailable for this phone number."
Not every twilio number is capable of sending / receiving SMSs. Take a look into https://www.twilio.com/help/faq/sms/can-i-send-or-receive-text-messages-with-a-twilio-toll-free-phone-number
Also, if you follow the link they provide there, you can read the following
Mobile numbers
In most countries, mobile numbers are assigned to a particular range within the country’s telephone numbering plan so they can be easily distinguished from local numbers. They are often the only type of number in the given country that can be used for sending and receiving messages.
Note that currently all mobile numbers Twilio provides are only SMS-enabled. You can not make or receive voice calls using these numbers.
I faced the same issue with the "first one's on us" number.
Turns out, messaging capability depends on the type and country of the number.
I was automatically assigned a local number for my country, which did not allow messaging. If, however, you choose a custom number and go for one in the US, you are given SMS capability (at least I was just now).
If you already have your one free number assigned, you can release it and choose a new number for free.

I have had a couple of customers wondering if they can use their own phone numbers to send out SMS using Twilio.
I am wondering if this is possible?
What are the carrier charges in this case and do I need to verify this number before enabling this functionality for an individual user?
The number you want to send messages from (or to) needs to be controlled by Twilio. However, it is possible to port your number from your current provider over to Twilio and thus give Twilio control over that number. This is possible, at least in some countries.
This support article here describes how this can be done for US numbers.
So I'm using Zapier to send text messages to people added to a MailChimp mailing list. A lot of the subscribers are from other countries so I'm just wondering how the interaction works with Twilio.
Will I need a separate number for each country?

You don't necessarily need another number, Twilio numbers can send internationally (mostly, check the individual settings on the number to be sure, UK landline numbers, for example, can't send internationally).
However, receiving a message from an international number may not be a good experience for your users as they might expect a local number. Good news is that it is easy to build this.
You can create yourself an SMS messaging service. Messaging services are a combination of a number pool along with smart uses of the number pool. You can start your messaging service with one number and add others later. When you add more than one number the messaging service will geomatch between the people you are sending to and the numbers available in the pool, picking the best number for the user.
I'm not entirely sure how this works with Zapier, whether you can set a messaging service ID for your Zap. If that's not possible, you could use Zapier to send a webhook to something like a Twilio Function which you could set up to send the message.
Let me know if that helps at all.
We want Caller ID to display our company name on outbound calls.
According to Twilio, numbers purchased from them cannot have Caller ID/CNAM added.
If we transfer numbers from another service that can add the numbers, will the CallerID/CNAM be maintained.
Should we Port the Number or have Twilio host the number? What is the difference?
Tried to purchase numbers on Twilio and have CNAM added.
Have purchased numbers from another vendor and they were able to add CallerID
Based on my experience recently migrating several numbers to Twilio:
If we transfer numbers from another service that can add the numbers, will the CallerID/CNAM be maintained?
Supposedly yes, mine did not. I had three Spectrum landlines, with working outbound caller ID. At some point after porting them to Twilio, the caller ID disappeared. What's worse is that some cellphones will try and "guess," and show random people's names instead of my business name (or at least, nothing).
What is the difference between porting and hosted numbers?
Hosted SMS provides a method for customers to use Twilio’s Programmable Messaging, Functions and Studio products to send and receive messages on voice-enabled numbers they already own as part of an established voice application.
(from https://www.twilio.com/docs/phone-numbers/hosted-numbers)
So porting is moving the number entirely to Twilio as the carrier for the number - voice, SMS, possibly fax (although Twilio's fax support is minimal). A hosted number would just enable SMS through Twilio for a non-Twilio landline number.
I have been looking for a way to get my numbers listed back in the CNAM database(s), today I tried a company called TrueCNAM (https://www.truecnam.com/) who will let you list up to five numbers for free. I went ahead and listed mine, I'll update my answer if I verify that it's working. Currently the CNAM lookup for my numbers is blank, so we'll see what happens.
Edit: I also tried verifying my number at https://listyourself.net, but I'm still not seeing the number in a couple searches I've done on it. It looks like the changes may take a while to propagate to the downstream third-party CNAM databases, based on this: https://www.dslreports.com/forum/r26461709-
I am trying to work on Twilio Copilot. I have created the SID.I have also assigned a UK number .I need to send messages to UK, US and South africa for now.
I am currently facing problem is sending messages to US. Do i need to assign a seperate US number for it to work (Same for Other Countries)?
I am using C# Twilio 4.7.2 library.

My guess is that you have a UK landline number. That is a number that currently supports voice and messaging and starts +441, +442 or +443.
UK landline numbers cannot currently send international SMS.
If you still want to use a UK number to send international messages, you can get a UK mobile number, which will start +447, though currently these numbers do not support incoming voice calls.
Best practice for sending international messages is to try to use a local number to send them. When you are using Copilot it will automatically geomatch the best number to the location you are sending to.
How does one link a single twilio number to multiple phones such that:
When new people text the twilio number, all of the phones linked to the twilio number receive the text.
When any one of the twilio phones respond to the text, it appears to the original texter that a single number is responding to them (irregardless of which of the twilio phones sends the text).
Picture texts work also in the way described in (1)-(2).
This is very similar to what Google Voice can do, except google voice sometimes doesn't work with picture texts.
You would need a backend of some sort, where you can store subscribers for a number, you can then handle in your language of choice, when you receive a sms perhaps containing the word "subscribe", you would then simply save that into your backend along with the number that the sms was received upon.
When receiving a sms that contains other text, you would then simply query your backend and find all the numbers that have subscribed to the number that you have just received the sms on, you would then simply use the Twilio api, to send the message to all the results from your backend query.
You could also allow unsubscribe functionality, where users only have to send unsubscribe to the number, and you would remove them from your backend or flag them as to not send to them again.
