1️⃣ Your internet connection is weak or unstable
Beside uses your internet connection (Wi-Fi or mobile data). If the signal is weak or unstable, your call may fail, drop, or lose audio.
👉 How to fix
Move to a place with stronger signal
Switch between Wi-Fi and mobile data
Restart your router
Close apps using heavy bandwidth
💡 Try switching to cellular network during a call
You can switch seamlessly without hanging up:
During a call, tap the 🛜 icon in the top-right corner of the screen
Choose “Call with cellular network”
If needed, tap “Hang up & call with cellular”

2️⃣ Call Forwarding conflicts (carrier-level)
If you’re forwarding your personal phone number to Beside, incorrect carrier forwarding can cause:
Calls failing to connect
No audio
Calls disconnecting
👉 How to fix
Turn Call Forwarding OFF on your carrier line
Turn it ON again using the in-app setup steps
Make sure the right line is being forwarded to your Beside number

3️⃣ International calls are not supported
Beside currently supports calls only to U.S. and Canadian numbers.
What this means
Calls to numbers outside the U.S. or Canada will fail
You can still receive international calls to your Beside number
Outgoing international calling is not available yet
👉 How to fix
Use your personal carrier’s international calling plan for numbers outside North America.

4️⃣ AT&T forwarding limitations
A small portion of AT&T users (~5%) may experience issues with forwarding their AT&T number to Beside due to how AT&T handles third-party call routing.
Symptoms
Dropped calls
No audio
Calls not ringing
This is a known limitation with how AT&T handles call forwarding to third-party numbers like Beside. Unfortunately, there’s no fix we can apply on our end.
👉 How to fix
If you’re affected, you have two options:
Use your assigned Beside number directly, without forwarding from AT&T
Or forward a number from a different carrier (e.g., Verizon) instead.
5️⃣ T-Mobile to T-Mobile Caller ID conflict
Calls may fail when all of these conditions are true:
You are forwarding a T-Mobile number to Beside
Caller ID is enabled in your Beside settings
You are calling another T-Mobile number
👉 How to fix
Disable Caller ID in Beside settings before making the call.
