Country Code Restrictions
What Are Country Code Restrictions?
Country code restrictions allow you to limit which countries your users can call or send SMS to. This prevents accidental (or unauthorized) international calls and messages that could result in high carrier charges. Available on Reach and Record subscription plans.
Configuring Restrictions
In the SIMtrix dashboard, go to Settings > Country Codes. You can either create an allowlist (only selected country codes are permitted) or a blocklist (selected country codes are blocked). For example, if your business operates only in Poland and Germany, you can allow only +48 and +49.
How It Works
When a call or SMS is initiated, SIMtrix checks the destination phone number against the configured restrictions. If the destination country is restricted, the command is blocked before it reaches the Android phone. An error message is displayed in Bitrix24.
