Other Features / Restrictions of Note

Reach to virtual numbers: While Google Voice numbers are reachable through Nexmo, we do not provide reach to other virtual number providers due to fraud prevention precautions. If you have any particular business case where you would like to be able to reach virtual numbers, please contact our Support team with details about your use case.

Current “Text-To-Donate” campaigns will continue to be allowed. Campaign Submissions that include donation capabilities by being directed to a website for credit card donations or other methods, will not be approved.

*Unicode is not supported on US Cellular; they support ASCII.
**Nexmo's 2FA and Alerts pre-approved short code API's can reach Canada mobile phone numbers since we can identify the destination number and change the sender ID as needed (via a pool of US long codes).
