Calls are billed per second. SMS are billed by SMS, where each SMS represents a single text message of up to 160 characters (using the standard GSM character set). If a message exceeds this limit, it may be split into multiple SMS, each billed separately.

Regardless of the package selected, MMS functionality remains disabled.

Absolutely! You can port your existing number to our services. We will only need an invoice of less than three month from your current operator, then we will manage the porting.

If you use up all the data in your mobile plan, your data will be blocked. If you need additional data, we offer the option of an eSIM. This allows you to access extra data no matter where you are, ensuring you stay connected without hassle.

An SMS is limited to 160 characters when using standard GSM-7 encoding (the most common encoding for text messages). This includes spaces, punctuation, and special characters. If your message contains characters not supported by GSM-7 (e.g., certain emojis or non-Latin characters), it will be sent using Unicode encoding (UCS-2). In this case, the character limit is reduced to 70 characters per SMS. For longer messages, SMS uses a feature called "concatenation" to split the text into multiple parts. Each part reserves characters for linking, reducing the effective limit to 153 characters per part for GSM-7 or 67 characters per part for UCS-2. For example: • A 300-character message in GSM-7 will be split into 2 parts of 153 characters and 1 part of 94 characters. • A 300-character message in UCS-2 will require 5 parts of 67 characters each. The price for sending SMS is calculated per part, so longer messages may incur higher costs.

Yes, if you select "Always" when prompted. The first time you tap a Tel link on your mobile device, you will be asked to choose an app to handle the call and whether to use it “Just once” or “Always.” To ensure all Tel links are handled by Voxbi going forward, select Voxbi and tap Always. If you want to revert to the default settings for handling Tel links, open the App info (from the device’s settings or long-press the Voxbi icon, then tap in the top-right corner to open App info). Tap on the Set as default section, then tap on the Clear button. Next time you tap a linked telephone number, you will be asked to choose which app should start calling and if you want to use it “Just once” or “Always.”

Ensure the Voxbi app has call permissions enabled in your Android device settings. If necessary, reinstall or update the app to ensure it registers properly.

When you tap a TEL link, your phone will prompt you to choose an app—select Voxbi to place the call through your Voxbi mobile app.

After you have installed the app on your phone, go to your device’s settings and make sure the Voxbi mobile app has permission to access your phone’s calling feature.
