Country Code Blocking — Prevent Unexpected International Charges
Define which country codes your team can call or SMS. Block international numbers to prevent accidental charges on your mobile plan.
Control Where Your Team Can Call
Whitelist allowed country codes. Block everything else.
Allowed Country Code List
In the SIMtrix admin panel, define which country codes are permitted: +48 (Poland), +49 (Germany), +44 (UK), etc. Calls and SMS to numbers outside the allowed list are blocked before they reach the phone.
Per-SIM Configuration
Country code rules can be set per SIM card. Allow international calls on the business SIM but restrict the support line to domestic only. Each SIM has its own allowed list.
Block Before Dial
Blocking happens on the server before the call command reaches the phone. No accidental international calls, no surprise charges on your next bill. The user sees a clear message that the destination is blocked.
