Overview

Quo supports international text messaging to most countries worldwide at competitive rates. Message delivery and sender ID display vary by destination country due to local regulations and carrier requirements. Some countries support full two-way messaging while others are send-only.
International messaging requires international calling to be enabled and sufficient credits in your account.

Sender ID and two-way messaging

How sender ID works internationally

US and Canada messaging: Recipients always see your Quo number as the sender ID, enabling full two-way conversations. International messaging: Sender ID display depends on the destination country’s regulations and technical capabilities. Some countries maintain your Quo number while others use alternative sender IDs.

Countries with two-way messaging

Recipients in these countries see your Quo number and can reply directly: European countries:
  • Austria, Belgium, Czech Republic, Denmark
  • Estonia, Finland, Hungary, Netherlands
  • Poland, Portugal, Slovakia, Sweden, Switzerland
Other countries and regions:
  • Canada, Chile, Hong Kong, Israel, Singapore
Two-way messaging means recipients can reply to your messages and their responses will appear in your Quo inbox.

Countries with send-only messaging

For most other countries not listed above, you can send messages but recipients may see a different sender ID. They cannot reply directly to your Quo number. Alternative sender ID reasons:
  • Local regulations requiring specific sender formats
  • Carrier technical limitations
  • Delivery optimization requirements

Special restrictions
