Dual SIM Support — Two Numbers, One CRM
Assign each SIM card to a different Bitrix24 user. Personal and business numbers on one phone, both integrated with your CRM.
Full Dual SIM Integration
Each SIM card is independently configured and tracked in Bitrix24.
Per-SIM User Assignment
Assign SIM 1 to one Bitrix24 user and SIM 2 to another — or both to the same user. Calls and SMS are attributed to the correct user based on which SIM was used.
SIM Selection for Outgoing
When making outgoing calls or sending SMS from Bitrix24, you can specify which SIM card to use. Call business contacts from your business number and personal contacts from your personal number.
Independent Configuration
Each SIM can have different settings: one for calls only, the other for calls and SMS. Enable recording on the business SIM, disable it on the personal one. Country code blocking can differ per SIM.
How It Works
Set up dual SIM in the admin panel.
Register Phone with Dual SIM
When the Android phone connects to SIMtrix, both SIM cards are detected and registered.
Assign Users per SIM
In the admin panel, assign each SIM to a Bitrix24 user and configure permissions independently.
Use Both SIMs from CRM
Make calls and send SMS from Bitrix24 — choosing which SIM to use for each action.
Who Is This For?
Dual SIM is valuable for teams that use both personal and business numbers.
Sales Reps
Keep your personal number private. Use SIM 1 for CRM calls (logged) and SIM 2 for personal calls (not logged). One phone, clean separation.
Multi-Brand Businesses
Two SIMs, two brands. Calls from each SIM are attributed to the correct business unit in Bitrix24.
Shared Devices
Two team members sharing one phone? Each gets their own SIM, their own Bitrix24 user, their own call history.
