Common errors in agency settings


Reached maximum numbers of subaccounts:


If you are on trial with Twilio, you can only have one subaccount. Once you upgraded Twilio, the maximum number of subaccounts will be 1000 subaccounts. Closed subaccounts do not count towards this limit.


If your upgraded project is approaching 1000 subaccounts, please contact Twilio Support to ask about raising this limit.

Media Message - Media exceeds messaging provider size limit

ErrorCode: 30006
The destination number is unable to receive this message. Potential reasons could include trying to reach a landline or, in the case of short codes, an unreachable carrier. 



ErrorCode: 30007

Your message content was flagged as going against carrier guidelines. Your message was filtered (blocked) by Twilio or by the carrier. This may be done by Twilio for violating Twilio’s Messaging Policy or Acceptable Use Policy, or by a wireless carrier for violating carrier rules or regulations.



ErrorCode: 30002 / Authenticate

Your account was suspended between the time of message send and delivery. Please contact Twilio. This message failed because your account was suspended after this message was queued but before it was sent by Twilio.

ErrorCode: 30004

The destination number you are trying to reach is blocked from receiving this message.



ErrorCode: 21612

The 'To' phone number: {{contact.number}}, is not currently reachable using the 'From' phone number: +61000000000 via SMS.



Solution: 

You can try to enable geo permission here. However, to guarantee two-way messaging (receiving incoming messages from end-users), you must use a number from the same country as your recipient.


It's best to buy a phone number for the country your contact is in and use that as the default one. And delete the old default Twilio number.


Since the current leads will be stuck with the original Twilio number as explained here:


If you want to keep the original Twilio number, you can assign the phone number to the user, then assign the lead to the user, then you will be able to send from the new number.


Another way is to recreate the contact.
