Voca calls and messages are transferred via the Internet, meaning that you will need access to Wi-Fi or 3G for the service to work.

Voca-to-Voca calls and texts are free and unlimited. In your list of contacts you can easily spot other Voca users by the green Voca icon.

Q.3 How do I get Voca on my device?

Q.4 Why does Voca require my Cell-Phone Number?
Voca requires an existing mobile number to validate your account and send you the activation code.

When making a Voca call your cell-phone number will appear as the Caller-ID so that your contacts recognize who's calling.

Please note that data-only SIM cards lack the functionality to receive text messages, using the number associated with your Data-only SIM card will not allow us to send you a validation code.

Q.5 Why does Voca ask permission to access to my contacts?
Voca requires access to your contacts to enable free calls between users. In addition, having all your contacts in Voca makes the service easy to use. Changes in your regular phonebook are automatically detected and updated in Voca.

Q.6 Why does Voca ask permission to access to my microphone?
Voca requires access to the microphone of your device in order for the service to work.

Q.7 Why does Voca ask me to allow push notifications?
Voca needs to send a push notification to your Voca app for you to receive incoming Voca calls and messages.

If you do not allow Voca to send you push notifications the service will not work.

Tips and Hints

Q.1 Should I use 3G or Wi-Fi?
When using Voca to make calls, an internet connection is required - either Wi-Fi or 3G. If using 3G, check with your 3G provider that you have a fixed data plan so that you will not be charged for extra data usage.

You can use Voca to make calls while abroad or while travelling, in these cases we recommend using Wi-Fi in order to avoid data roaming charges.

Problem Solving

Q.1 I have WiFi or 3/4 G coverage but the call quality is bad.
As when using your mobile phone, geographical factors, coverage and speed of the network have an impact on call quality. A poor network or signal might cause lags.

If you are experiencing bad sound quality when calling, it’s most likely connected to problems with your internet connection.

When making a Voca call the data signal strength is displayed in the top right hand corner of the call view.
- Four green bars expect good call quality.
- Three orange bars expect average call quality.
- One or two red bars expect bad call quality.

Regardless if you are using 3G or WiFi the signal strength varies depending on distance and things that might block the signal, such as walls, buildings and so on. If the signal strength is weak, try to find a spot where it’s stronger.

Q.2 Unable to call
If you're experiencing difficulty making an outgoing call, please check the following:

Make sure that your device is connected to a WiFi or 3G network when you’re making a call

If you are calling another Voca user, check with them to see if they're connected to a WiFi or 3G network and that they are also logged in to Voca

If you are calling a non-Voca user, please check your balance to make sure that you have credits.

If you have verified all the above and you still can’t make the call, please contact us and include the following information:
- Your number
- The number you are trying to call​
- Which device are you using?
- Are you connected to a 3G or to a WiFi network?
- Are you calling a Voca or a non-Voca number?
- The exact time of the attempted call

Q.3 Unable to receive calls
In order to receive notifications of incoming calls and messages, first, please check to see that you have a working 3G or WiFi connection since an internet connection is required when using Voca.

If you have Voca on an iPhone, iPod Touch, or iPad, you will need to enable Voca push notifications in order to receive notifications of incoming calls and messages.

Q.4 Unable to view Balance
If you can not see your balance, please try closing the Voca application and then restarting it to refresh your statement.

Q.5 There is no ring signal for incoming Voca calls.
Check if the phone is muted.

If you are using an iPhone or iPad you will not get a ring signal if you have a headset connected. This is an Apple limitation.
