Remove a cell number from the Twilio unsubscribe list - twilio

I have a very simple alert mechanism to alert drivers "in-the-field" when a new pickup has been assigned to them. I have had an instance twice where a driver has responded with a STOP and became un-subscribed. Once discovered we acquired the proper opt-in documentation from them. Is there any way to re-subscribe a user that opted out and changed their mind on receiving the messaging. i.e. they issued the STOP to the incorrect SMS. And have deleted the original message to START. Or do I need to code something for them to opt back in
My SendGrid provides a method to remove suppression from email but am not finding anything like that here in Twilio.

They need to send a START to the number they previously opted out of, this is currently a requirement. You will also get an error when trying to send messages to them, to alert you they opted out.
Error 21610 - Attempt to send to unsubscribed recipient

MS Teams bot events

I have a notification-only bot, and I would like to send a welcome message to users only when the bot is added to a personal conversation.
I listen to 'conversationUpdate' events as stated here, though I keep receiving the same event multiple times one after the other for the same user, all events identical (except the event ID and timestamp).
I respond to the event with HTTP status 200 (I handle them via REST).
Does anyone have an idea why I would receive the same events multiple times and how to avoid it? Is it some kind of retry due to an unexpected response on my end?
It even says here: "For personal scoped bots, your bot will only ever receive the conversationUpdate event a single time, even if the bot is removed and re-added."

Swift Clear specific remote notifications

We are currently developing an IOS application. The app should basically inform the staff member about new events/requests and the staff member has the option to cancel or accept the event (e.g. customer asks: "I d like to have a coffee", the staff member says: "okay, I'll do it" or "sorry, can't do it"). The idea is that the request appears on multiple smartphones (from multiple staff members) at the same time and that the notification has the buttons for accept/reject included.
The thing is we would like to solve this using Notifications (remote). But there is one thing which is not clear to us. Lets says I receive three requests/notifications. But until I have time to check them, on of the other staff members already resolved one of those requests. Is it possible, that this given requests can be cleared/removed from all staff members phones? Because otherwise I am handling a request that has already been resolved?
And what would be the best option to solve it.
Push remote notifications for every request
Push silent notification for every request and then clear out all notifications on the client, get the new/current requests using REST (GET) and add a local notification for every request?
Thanks a lot for your help.

I think second option is good.
you can refresh the data using REST api after receiving silent push.
I'm thinking best option is use Push silent notification because end user (Application Holder) will not get clue of that and it is best for us.
I would recommend 1st option
Send remote notification for every request
Handle duplicate request from backend
I think 2nd option is not reliable
APNs treats silent notifications as low priority and may throttle their delivery altogether if the total number becomes excessive. The actual limits are dynamic and can change based on conditions, but try not to send more than a few notifications per hour - source

Ejabberd offline messages

I have set up a chat server with Ejabberd, It is working fine. Messages are getting sent from one user to another user. Problem is that when the receiving user is offline, Sender messages should get stored and get delivered to receiver when he comes back to online. But offline messages are not getting delivered. I have not changed anything in configuration file because it looks already configured for the offline storage and offline message delivery. Do I need to make any other changes apart from the below lines?
ejabberd.cfg:
{access, max_user_offline_messages, [{5000, admin}, {100, all}]}.
{mod_offline, [{access_max_user_messages, max_user_offline_messages}]}
Please update your ejabberd from 2.1.10 to 16.10, as you using the older version certain func. may not work as expected.

STOP for a single campaign

I do not completely understand how to handle STOP messages if I have only one campaign. Should I respond with "... text 1" when I receive STOP or can I simply opt out the user without asking them to send '1'?
EDIT:
I am trying to implement message handling for a SMS short code to be compliant with the carrier requirements. https://www.twilio.com/help/faq/short-codes. Basically, to be compliant with the requirements, I have to handle specific SMS messages that I receive, in particular, STOP message that should opt out the number that sent it from my "campaign". A "campaign" is intuitively a series of SMS messages that I sent to users. Here is Twilio help entry that explains STOP messages.
I do not understand whether I have to ask the user to text me back 1 as the page suggests if I have no other choices. Can I just handle this STOP as I would do STOPALL?
Here is a response that I received from Twilio support, in case someone else wants to ask this "non programming related" question:
"If you have one campaign, then you can opt them out the same way you would do a STOPALL."

How to send message with a single tap

I want to send message to multiple people with single tap i..e, without opening the MFMessageViewController .
I'll Configure the senders list and message to be send with NSUserDefaults.
Can we able to send without viewing the MFMessageViewController.
No, this is not possible with the Public SDK.
The user will always have to send the messages them selfs. This is probably done to make sure that you do not send 100 of messages to paid services.
