Hi Debashish,
To enable multiple countries for SMS or voice calls in your Twillio account, you must configure the Geo Permissions setting in the Console. By default, Twilio restricts outbound messaging and calling to the home country verified during signup to prevent fraud.
How to change SMS Geo Permissions
Info
SMS Geo-Permissions can not be changed programmatically via the API for security reasons.
Warning
Only users with Account Owner and Account Admin profiles can modify SMS Geo Permissions.
Step 1 - Navigate to Messaging Geo Permissions settings
Ensure you are logged into the Twilio Account for which you want to change the permissions.
Navigate to Console > Messaging > Settings > Geo Permissions.
Step 2 - Adjust your SMS Geo Permission settings
Info
SMS Geographic Permissions generally work based on the country code of the destination phone number. However, exceptions exist for political and historical alignments and some may not map strictly to a country's political or cultural boundaries.
Find the country or region for which you want to adjust the SMS Geo Permissions. You can do so by scrolling through the displayed listing arranged by continent or you can use the Filter by Country input control to narrow the search.
Once you have found the country or region whose permissions you want to adjust, use the checkbox control next to its name to enable or disable it.
- Filter by country control
- Country checkbox
Warning
Some countries or regions will have a High Risk marking next to their name. Twilio has assessed them to currently have the highest risk of SMS Traffic Pumping Fraud.
As conditions change, e.g. due to enforcement actions or evolving bad actor behavior, Twilio's continuous monitoring activities may lead to adjustments of its risk assessments and result in changes to which countries or regions are marked as High Risk.
Click on the High Risk marking to see a tooltip with additional information.
Step 3 - Save your Geo Permission changes
Press the Save geo permissions button. An appropriate dialog opens to ask for your confirmation to proceed with saving the changes.
Danger
Saved changes to SMS Geo Permissions take effect immediately.
As a result, as soon as you save the changes that disable the SMS Geo Permissions for a destination region, SMS to this destination will no longer be sent.
When trying to send an SMS to a recipient (to) whose region has disabled SMS Geo Permissions, you will receive an Error 21408.
