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.”
