Error trying to register a Sandbox destination phone number in Europe (London)
Hello,
I am trying to configure an SNS topic to post to a phone number in my AWS account. I have tried to verify a Sandbox destination phone number through SNS, but when it tries to send the verification code I get the following error
An error occurred while attempting to send a verification code to the destination phone number.
Error code: UserError - Error message: No origination entities available to send
From what I can tell I already have a registration and a Sender ID as an origination as shown below
And according to the this using a Sender ID is supported in the UK as long as I have it registered (but I have not registered with MEF)
I have followed all the troubleshooting steps in this post (aside from making the infrastructure in a separate region) but I still can't get it to work. I have even sent it to a message to simulator number and that works fine.
Finally the phone number is definitely correct, in the right format, and is able to receive message
Does anyone have any advice?
Thanks

Hi there,
The error you got means that your account does not have an appropriate origination number or Sender ID configured that is eligible to send SMS messages to the UK.
There is no explicit requirement from AWS that MEF registration is needed for sandbox destinations, unless you are trying to use a Sender ID that is already protected in the MEF registry. If you attempt to use a protected Sender ID, AWS will require you to complete the MEF registration and provide the necessary documentation. This is to prevent fraud and spoofing of trusted brands. AWS recommends that you choose a Sender ID that matches your company branding and SMS service or use case.
Because UK requires sender ID registration, if you choose another sender ID that is unique to your brand but hasn't been registered yet, AWS End User Messaging SMS attempts to deliver the message with the Sender ID NOTICE. The message might not be received by the recipient based on the carrier requirements as some carriers might filter out messages with sender ID NOTICE. This could be due to security policies or anti-spam measures implemented by the carrier.
