What is MyOwnSIM?
MyOwnSIM is a business SMS gateway that connects your Android device to your CRM system, enabling SMS campaigns, missed call text-back, and caller ID features directly from your phone.
How does MyOwnSIM work with my CRM?
The app acts as a bridge between your CRM and your phone's SIM cards. It receives commands from your CRM to send messages and forwards incoming communications back to your CRM for automated responses.
Do I need special hardware?
No. Any Android device with dual SIM support works. We recommend a dedicated device for business use.
How is billing handled?
Your CRM provider handles all billing. innexum provides the mobile gateway application only.
Setup & Installation
Where can I download the app?
Download the APK directly from your CRM provider's platform. The app is not available on Google Play Store.
What permissions does the app need?
Phone state and call log access
Can I use both SIM slots?
Yes. Each SIM card can be configured independently with different settings and campaigns.
How do I connect to my CRM?
Scan the QR code provided in your CRM dashboard during initial setup. This links your device to your CRM account.
What is missed call text-back?
When someone calls and you don't answer, the app automatically sends an SMS response. The AI can generate contextual replies based on your business settings.
Yes. When configured, incoming calls display client information from your CRM database.
Can I send bulk SMS?
Yes. Your CRM system sends campaign instructions to the app, which processes them through your SIM card's carrier.
Does it support MMS?
Limited. MMS functionality depends on your carrier's APN settings and network configuration. Most modern use cases favor standard SMS.
Technical Questions
Does my phone need to stay on?
Yes. The device must remain powered on with an active internet connection to receive CRM commands and forward messages.
What happens if internet disconnects?
Outgoing messages queue locally and send when connection restores. Incoming messages are logged and synced once online.
Can I use my personal SIM?
Technically yes, but we strongly recommend dedicated business SIMs to avoid mixing personal and business communications.
How are updates delivered?
The app checks for updates automatically and prompts you to install new versions directly (APK updates).
Privacy & Security
Where is my data stored?
Message logs and settings are stored locally on your device. Communication data syncs with your CRM's backend systems.
Who has access to my messages?
You and your CRM provider. Innexum OÜ does not access message content.
Is my data encrypted?
Yes. Communications between your device and CRM backend use encrypted connections.
Troubleshooting

Can multiple staff use one device?
The device links to one CRM subaccount. Different staff access campaigns through the CRM interface, not the mobile app.
You can apply manually permission to other users to communicate with a client, even if their SIM is not linked with their subaccount, but you would have to assign that contact again to the former user to continue communicating.
What carriers work best?
Any major carrier with reliable SMS service. Test MMS capabilities if needed for your use case.
Is there a message limit?
Carrier limits apply (typically 100-200 per hour per SIM). Your CRM may have additional rate limiting.
Can I switch devices?
Yes. Disconnect the old device in your CRM settings and scan the QR code with the new device.
Who provides technical support?
Contact your CRM provider for account and campaign issues. App-specific technical issues go through Innexum support channels.
How do I report bugs?
Use the feedback option in your CRM dashboard or contact your CRM provider who will escalate to Innexum if needed.
Are there video tutorials?
Check your CRM provider's documentation. They typically provide setup and usage guides specific to their platform integration.
