International SMS Sending and Receiving

This section discusses inbound SMS messages not reaching your Avorra numbers as expected.

Here are some troubleshooting steps to check:

Are you expecting to receive SMS from an international number (a different country than your Avorra number)?

Our platform promises support for receiving SMS messages within the same country as your Avorra SMS-enabled number. For example, a German mobile number can deliver SMS to a German Avorra mobile number. If you ever encounter delivery issues on in-country incoming SMS, please contact us for support.

For non-domestic incoming SMS, some international carriers are unable to successfully pass off SMS into Avorra's network. Because of this, Avorra cannot guarantee that incoming messages will be received. For example, a German mobile number may not be able to deliver an SMS to an Avorra USA number.

For this reason, we recommend always using an Avorra number local to your sender if you need to receive an SMS.

In cases where non-domestic SMS are failing to reach Avorra, the sending party may choose to reach out to the sending carrier to troubleshoot.

Please note, however, that receiving non-domestic SMS is not officially supported by Avorra and may not be successful.

Are you expecting to receive SMS from a short code?

Avorra accounts can now be enabled to receive messages from short codes. This is an account-wide setting, which will apply to all long code numbers set up in your Avorra account.

Your account must have an Avorra number from the same country as the short code from which you intend to receive messages. Short code numbers are always country-specific and can only communicate with numbers from the same country.

Please contact Avorra Support to have this option enabled on your account.

It is important to note that even when this feature is enabled, we cannot always guarantee delivery of these incoming messages due to factors outside of Avorra's control.

Are you expecting to receive SMS from an Alphanumeric Sender ID?

At this time, Avorra does not support receiving incoming SMS from external Alphanumeric Sender IDs.

An Alphanumeric Sender ID is not a phone number, but a string of letters and numbers, usually spelling the name of the business or entity sending the messages.

Are you expecting to receive OTP or 2FA codes?

2FA (Two Factor Authentication) and OTP (One Time Password) codes will often be sent from Short Codes or Alphanumeric Sender IDs.

Due to the limitations of these Sender IDs, discussed in the above sections, we cannot always guarantee the delivery of these incoming messages.

Please see the section "Are you expecting to receive SMS from a short code?" above for information on how support can help enable receiving SMS from Short Codes.
