Who is SIMtrix for?
See how SIMtrix solves the specific problems of your team
Switching between phone and CRM wastes 30+ minutes daily
Call history is incomplete — reps forget to log conversations
No way to send quick SMS follow-ups directly from the deal card
One click on the contact card — phone rings, call logged automatically
Every call, every SMS saved on the Lead/Deal/Contact timeline
Personalize your SMS with variables (e.g. {client name}, {company}) directly from CRM cards
Incoming call — no idea who's calling until you check CRM manually
SMS from clients logged as notifications, not on the contact timeline
Missed calls disappear — no automatic follow-up task created
Smart Caller ID — contact card opens on your computer with name, company, last deal before you pick up
Full SMS conversations on the contact card — like a chat, not notifications
Missed call → automatic unprocessed activity in CRM with configurable scenarios
SMS gateways cost €0.04–0.11 per message — 1000 SMS = €100+
Android and carrier limits block bulk SMS after a few messages
No way to schedule campaign delivery windows or control send rates
Send through your SIM card — unlimited SMS included in your mobile plan
Smart queuing bypasses Android and carrier limits with configurable intervals
Personalize campaigns with variables (e.g. {name}, {company}) and control hours, days, send intervals
VoIP systems cost €19–28/user/month with per-minute charges on top
Clients don't recognize VoIP numbers — they don't pick up
Setting up VoIP requires technical knowledge and ongoing maintenance
Use your existing SIM card — pay only your carrier's rates (often unlimited)
Clients see your real phone number — the one they already know and trust
Setup in 5 minutes. No servers, no PBX, no technical skills needed.
Field Workers & Real Estate Agents
Agents and reps working outside the office, calling from their phone
Try freeCalls made in the field are never logged in CRM — data is lost
Can't send SMS about properties or offers directly from CRM while on the go
Unknown callers — no CRM context when the phone rings in the field
Every call through SIM automatically logged on the Bitrix24 contact card
Send SMS from Lead/Deal cards on mobile — works on WiFi, 4G, 5G
CRM contact card opens on your computer with caller info before you pick up — even outside the office
Clients need telephony but VoIP setup is complex and time-consuming
Every client has different carriers, numbers, and SIM configurations
No recurring revenue from telephony — just one-time setup fees
Deploy SIMtrix in 5 minutes — client installs app, connects SIM, done
Dual SIM support, per-user SIM assignment, multi-phone management
