Yolla is an application that lets you make free HD quality calls to other Yolla users and premium quality calls to any phones all over the world at low rates. Yolla uses your cell phone’s internet connection, be it WiFi, 3G, 4G/LTE instead of your phone credits.

Your friends and family always get calls from your personal phone number. They know it’s you and can even call you back!

All Yolla to Yolla calls are completely free. Moreover, it is really easy to earn free credits to call to landlines and mobiles by inviting friends.

*Please note that data charges may be applied by your service provider if you are using cellular internet connection.

1. Please ensure you enter your phone number in international format with the country code.
   Example: +965 123 45 678
   You don't need to type "+" - it is added automatically. No 00 or 0 after the country code unless it is the part of your number. If it doesn't help, please send us your phone number and we will try to help!
    
2. If the validation message doesn't come, please wait for a validation call, or try again.
    
3. Some VoIP services may be blocked by Internet providers. To make sure Yolla is not blocked, just try to open yollacalls.com in your mobile web browser. If you can't open it, try using some other Internet connection.

1. Android users can enable the mobile phone billing in the Google Play app.
   Open the Google Play app > My Account > Add payment method > Enable 'your carrier' billing.
   Your carrier needs to be supported by Google Play (for example, Mobily, STC, and Zain are supported in Saudi Arabia).
   See the list of supported mobile operators (Direct carrier billing > Direct carrier billing availability).
    
2. Apple iOS users can set up some other payment method supported by Apple, including PayPal, Alipay, UnionPay, and the mobile phone billing (through supported carriers).
    
3. Yolla users in the Middle East region can use CASHU to recharge their balance.

Invite friends to Yolla to earn free credits after your friend tops up balance ($4 and higher deposits).

Open Get Free Credits (side menu of the Yolla app on Android or Gift button on iOS) to invite your friends, see the current reward campaign rules, and the amount of bonuses you can receive.

In order to get your bonus you need to make sure that your friends use the referral link that you have shared with them to download Yolla on their smartphone.

IMPORTANT: Please ask your friends NOT to switch the connection type (3G/WiFi) after clicking on the referral link.
If your friend will click the referral link in 3G network and then will switch to WiFi to download the app, or there will be some significant time between clicking the link and signing up, Yolla may not be able to track it due to technical restrictions.

Please note that there are certain technical limitations in our referral program:

• We would credit bonus to your account only when your friend has clicked on your referral link from his mobile device, installed the app and signed up right after the installation.
• Your friend must be the first-time Yolla user.
• If your friend didn't click the link and downloaded app directly from the store we won't be able to credit you bonuses.
• If your friend clicked on several referral links we would only credit bonus to owner of the last clicked link.
• Your friend should not switch connection type (e.g. 3G to Wi-Fi) during registration process.

There is a fixed per-minute rate that you see before making your call to cellular and landline phones. There are no hidden charges or connection fees in Yolla.

*Please note that data charges may be applied by your service provider if you are using cellular internet connection.

Yolla is available for:

• iPhone® 4s and higher (OS 8.0 and higher);
• iPad® (OS 8.0 and higher);
• Android™ phones (OS 4.1 and higher);
• Android™ tablets (OS 4.1 and higher).

You will need to sign in with the old phone number to use your old account on the other device.
Thus, you will need to put the old SIM in the new device or have the old phone with the old SIM nearby to verify your account on the new device.

Please note that the allowed amount of devices for your single Yolla account is limited. Please contact Yolla support for more information if you believe you have reached the limit.

Echoes are caused by feedback between the phone speaker and the microphone. If your contacts say there is an echo while talking (they hear their own words), the problem is likely on your end.

We recommend reducing the microphone and speaker volume on your device. To do so, when the call is in progress:

• tap the gear icon to open the microphone gain slider, and then set it to minimum;
• reduce the speaker volume with the volume buttons.

Please open the side menu on Android or Settings tab on iOS, choose Help and Support > Contact Support, and describe the issue that you are experiencing.
You may also send technical information to help Yolla Customer Care deal with the issue (Help and Support > More > Upload Logs).

Yolla doesn't store bank card data – the card information is safely treated by the payment processing system. For your convenience, you may still opt to use the same card for your next payment. In this case, you will not be required to enter the card details again, and the payment processing system will use the payment details you have already provided.
