What to Do If You Can’t Make Calls

If you are unable to make an outgoing call, please follow the steps below to troubleshoot the issue.

Step 1. Restart Your Phone

Turn your phone off and wait 30 seconds before turning it back on.

If you are using a physical SIM card, please remove it, reinsert it, and then power the device back on. 

Most issues can be resolved by simply restarting your device.

Once you restart your device, try making a call. If you still have the same trouble, move on to the next step.

Step 2. When You Cannot Call a Specific Number

Please double-check that the number you entered is correct (e.g., incorrect area code, missing digits, formatting errors). 

Also confirm that the number is a Canadian phone number.

Step 3. Check Your Active SIMs (Dual SIM Devices)

If your device has Dual SIM functionality and more than one SIM is active, the network signals may interfere with each other and prevent calls from going through.

Please turn off any SIM you are not currently using.

Step 4. Check Whether International Calling Is Supported 

If you are trying to call an international number, ensure that the country is included in the PhoneBox prepaid international calling list.
