SIMtrix vs myHub — Which Bitrix24 SIM Integration Is Right for You?
SIMtrix delivers 22 features that myHub lacks, including incoming SMS on CRM timeline, SMS campaign queuing, call recording with Bitrix24 upload, and a Chrome/Firefox extension — all in a single Bitrix24 app. Here is the full comparison.
How Do SIMtrix and myHub Compare at a Glance?
SIMtrix and myHub are both Bitrix24 SIM card integrations that let you make calls and send SMS through your Android phone. The key difference is scope: SIMtrix is a unified platform with 31 documented advantages across calls, SMS, campaigns, management, and privacy. myHub focuses on basic call and SMS relay with two separate Bitrix24 applications. This table compares every major feature as of March 2026.

How Do Incoming SMS Appear in Bitrix24?
SIMtrix writes incoming SMS messages directly to the contact's CRM timeline using Bitrix24's crm.activity.add and timeline.comment.add REST API methods. The full message text, sender number, and timestamp appear on the deal, lead, or contact card — exactly where your sales team works. This two-way SMS timeline creates a complete conversation history that is searchable, filterable, and visible to all CRM users with appropriate permissions. Based on our analysis of both products, this is the single most impactful difference between SIMtrix and myHub for teams that rely on SMS communication.
myHub handles incoming SMS differently. When a text message arrives, myHub sends a push notification to the Bitrix24 user. The message content does not appear on the contact timeline. There is no searchable SMS history inside the CRM. For teams running sales sequences via SMS, this means manually copying and pasting messages between apps — a process that typically adds 15-20 minutes per day per sales representative, according to CRM workflow research by Salesforce (2024 State of Sales report).
Which App Supports SMS Campaign Queuing with Intervals?
SIMtrix includes a built-in SMS campaign engine that queues messages with configurable intervals between sends. Administrators set the minimum delay (35 seconds recommended to avoid carrier throttling), define sending windows (e.g., 09:00-18:00 local time), and assign campaigns to specific SIM cards. The queuing system runs server-side using BullMQ with Redis, which means campaigns continue even if the admin closes the browser. Campaign progress, delivery status, and failure logs are visible in the SIMtrix management panel in real time.
myHub does not offer any SMS campaign functionality. Sending bulk SMS requires manual one-by-one sending from Bitrix24 contact cards or using a separate SMS gateway service. For businesses that run outreach campaigns, appointment reminders, or follow-up sequences via SMS, this gap means either adding another paid tool to the stack (Twilio, MessageBird) at a cost of approximately $0.04-0.11 per SMS — or accepting that campaign SMS is not part of the CRM workflow.
Note: SMS campaign queuing is available on SIMtrix Reach and Record plans. See pricing for details.
How Does Call Recording Work in Each App?
SIMtrix records calls on the Android device using the native Kotlin AudioRecord API with accessibility service fallback for Android 11+ devices. Recorded audio files are uploaded directly to the Bitrix24 contact timeline via the telephony.externalcall.attachrecord REST API method. The recording appears as a playable audio file attached to the call activity — managers can listen to any call without leaving Bitrix24. Recording is toggled per SIM card in the admin panel, giving administrators granular control over which employees have recording enabled.
myHub offers basic call recording that saves files locally on the phone. Based on our analysis of the myHub APK (version analyzed: March 2026), recordings are not automatically uploaded to Bitrix24. There is no in-CRM playback, no per-user recording toggle in the admin panel, and no audio enhancement processing. For compliance-focused teams that need call recordings attached to CRM records, this is a significant limitation.
Why Does the Number of Bitrix24 Apps Matter?
SIMtrix installs as a single application in the Bitrix24 Marketplace that handles both calls and SMS. One installation, one configuration, one webhook endpoint, one set of OAuth credentials. The Bitrix24 administrator manages everything from a unified SIMtrix panel — SIM card assignments, user permissions, call settings, and SMS settings in one place. This reduces the Bitrix24 REST API webhook quota consumption by approximately 50% compared to running two separate applications.
myHub requires two separate Bitrix24 applications: "MyHUB Android Call" (approximately 2,900 installations as of March 2026) and "myHub 2 Way SMS" (approximately 1,700 installations). Each application has its own installation flow, its own webhook configuration, and its own update cycle. Bitrix24 has a limit of 50 REST API calls per second per application — running two apps means managing two separate rate limits, two authorization tokens, and potential synchronization issues between call and SMS modules.
Which App Is Better for GDPR and Data Privacy?
SIMtrix follows a "Bridge, Not Storage" architecture — the server relays call and SMS event metadata to Bitrix24 but never stores message content or call recordings on its own servers. All data resides either on the user's Android device or in their Bitrix24 instance. SIMtrix servers are hosted in Germany (EU), use AES-256 encryption for data in transit and at rest, and provide full GDPR documentation including Terms of Service, Privacy Policy, Data Processing Agreement (DPA), and Cookie Policy — all available in 10 languages.
myHub is developed by a company based in Vietnam (myhub.vn). Based on our analysis, the myHub website currently shows an SSL certificate error, and the company does not publish a Data Processing Agreement or GDPR compliance statement. Server locations are not documented. For EU-based businesses subject to GDPR requirements, or for organizations that need DPA agreements with all data processors, this lack of transparency creates compliance risk. We acknowledge that myHub may have internal privacy practices that are not publicly documented.
Can You Click-to-Call From Any Website?
SIMtrix includes Chrome and Firefox browser extensions that detect phone numbers on any webpage and add a click-to-call overlay. Clicking the overlay triggers a call through the user's assigned SIM card via the SIMtrix Bridge Android app. The extension also offers a "Save to Bitrix24" option that creates a new contact or lead directly from the detected phone number. The extension works on any website — LinkedIn, company directories, email clients, support portals — not just inside Bitrix24.
myHub does not offer browser extensions for Chrome or Firefox. The click-to-call functionality is limited to the Bitrix24 interface. For sales development representatives who prospect outside of CRM (researching leads on LinkedIn, reviewing company websites, reading emails), this means switching to the phone app manually to initiate calls. SIMtrix eliminates that context switch entirely.
How Does Pricing Compare Between SIMtrix and myHub?
Both SIMtrix and myHub use per-SIM pricing. SIMtrix offers three plans with increasing feature sets (Connect, Reach, Record), while myHub offers a single tier. SIMtrix pricing starts at the same level as myHub but includes significantly more features at every tier. Both products offer a 14-day free trial.
When to Choose myHub
myHub may be a reasonable choice when your requirements are limited to basic outgoing calls and outgoing SMS from Bitrix24, and you do not need incoming SMS logging, campaign queuing, call recording in CRM, or browser extensions. myHub has been on the Bitrix24 Marketplace longer and has an established user base of approximately 4,600 combined installations across both applications.
- You only need basic outgoing calls and SMS
- You prefer a product with a longer marketplace history
- GDPR compliance is not a requirement for your organization
When to Choose SIMtrix
SIMtrix is the better choice for teams that need a complete SIM-to-CRM bridge — incoming SMS on the timeline, SMS campaigns with scheduling, call recordings uploaded to Bitrix24, CRM overlay on incoming calls, browser extensions for click-to-call from any website, and EU-hosted GDPR-compliant infrastructure. SIMtrix is built for organizations that treat phone and SMS as first-class CRM channels.
- You need incoming SMS logged on CRM contact timeline
- You run SMS campaigns or follow-up sequences
- You need call recordings attached to CRM records
- GDPR/DPA compliance matters to your business
- You want one unified app instead of two
Frequently Asked Questions
Can I switch from myHub to SIMtrix without losing data?
Yes. SIMtrix connects to the same Bitrix24 REST API as myHub. Your existing CRM data (contacts, deals, call logs) stays in Bitrix24. Install SIMtrix, configure your SIM cards, and uninstall the myHub applications. Historical call logs created by myHub remain in Bitrix24 — SIMtrix does not modify or delete existing CRM data.
Does SIMtrix work with the same Android phones as myHub?
SIMtrix requires Android 9 or higher with SMS and phone permissions. The SIMtrix Bridge app is a native Kotlin application (not React Native like myHub), which typically results in lower battery consumption and faster response times. Both apps support dual-SIM phones.
Is SIMtrix more expensive than myHub?
SIMtrix Connect plan costs the same as myHub ($3/SIM/month) while including more features — incoming SMS on CRM timeline, CRM overlay, and country code blocking. The Reach ($7) and Record ($12) plans add campaign queuing, call recording, and browser extensions. Both products offer 14-day free trials.
Why does myHub have two Bitrix24 apps?
myHub was developed as two separate products: one for telephony (MyHUB Android Call) and one for SMS (myHub 2 Way SMS). Each has its own Bitrix24 Marketplace listing, installation process, and webhook configuration. SIMtrix was designed from the ground up as a single unified application.
Where is my data stored with each product?
SIMtrix follows a "Bridge, Not Storage" model — SMS content and call recordings are stored only on your Android phone and in your Bitrix24. SIMtrix servers (Germany, EU) process event metadata in transit but do not retain it. myHub server locations and data retention policies are not publicly documented as of March 2026.
