How can I stop incoming calls from going to messages on my iPhone 13 mini?

If incoming calls are automatically being silenced to voicemail, that sounds like the Silence Unknown Callers setting which can be turned off in Settings > Apps > Phone > Silence Unknown Callers > Off.

But if you have more than one phone number, this could be the Call Forwarding feature. The setting to turn it off may also be on that page, but if not you'll have to contact your carrier as some require you do to configure carrier settings, or if any further help is needed to reach them.

By Messages, if you mean VoiceMail, then...

When your iPhone sends incoming calls directly to voicemail or is disconnected after a ring, it might be due to various reasons. This can occur if the recipient's phone is powered off, in a low signal area, or if they have enabled the "Do Not Disturb" mode. Additionally, the contact's number may be blocked or marked as spam.

1. Check your DND status - If you're experiencing issues with notifications or incoming calls, it's important to check your Do Not Disturb (DND) status. On most devices, you can access this setting by going to "Settings" and selecting "Do Not Disturb." Make sure DND is turned off or adjust the settings to allow desired notifications and calls to come through.
2. Check BedTime status - If you're using the Bedtime feature on your iPhone, you can track your sleep patterns and set a schedule for waking up and going to bed. To check your Bedtime status, open the "Clock" app and tap on the "Bedtime" tab. Ensure that your sleep schedule is accurately configured, allowing your device to provide sleep analysis and reminders accordingly.
3. Check your Sound Volume - If you're experiencing low or no sound on your iPhone, it's essential to check your sound volume settings. You can adjust the volume by using the physical volume buttons on the side of your device or by going to "Settings" and selecting "Sounds & Haptics." Ensure that the volume is turned up and not muted.
4. Check your Ringer switch - If you're not receiving any sound notifications for calls or messages, it's important to check the position of your device's ringer switch. Depending on the model of your iPhone, the ringer switch is located on the side or top of the device. Make sure the switch is not set to the silent or muted position.
5. Check Call Audio Routing - If you're having issues with audio during calls, such as not hearing the caller or distorted sound, you should check the Call Audio Routing settings. On an iPhone, you can access this by going to "Settings," selecting "Accessibility," and then "Audio/Visual." Ensure that the audio routing is set to the desired option, such as Bluetooth, speaker, or automatic.
6. Check Auto Answer Calls - If your iPhone is automatically answering calls without your input, it's important to disable the Auto Answer Calls feature. Go to "Settings," select "Accessibility," and then "Touch." From there, disable the "Auto Answer Calls" option to regain control over incoming calls.
7. Check Connection with Bluetooth Audio - If you're having trouble streaming audio from your iPhone to Bluetooth devices, it's crucial to check the Bluetooth connection. Make sure Bluetooth is turned on in the device settings, and try reconnecting your iPhone to the Bluetooth audio device. If the problem persists, you may need to unpair and repair the devices or troubleshoot further using Apple Support resources.
8. Check whether in Headset Mode - If your iPhone seems stuck in headphone mode despite no headphones being connected, it could be a software issue. You can try solving this by cleaning the headphone jack with compressed air or gently inserting and removing headphones a few times. If the problem persists, you may need to seek assistance from Apple Support for further troubleshooting steps or possible repairs.
9. On an iPhone, if the issue is isolated to a single contact, consider verifying the following:
   1. Silence Unknown Callers may be enabled, and the individual's phone number is not stored in your Contacts.
   2. The contact’s phone number may be incorrectly formatted or saved with an invalid or missing international dialing prefix.

Group Text/Chat messages on iPhone can come in various formats and types, each with its features and purposes (Which one you are referring to is not clear here):

1. Apple Platform (iPhone, iPad, and Mac)
   1. iMessage is Apple's proprietary messaging service, available only between Apple devices. iMessages are sent over Wi-Fi or cellular data rather than traditional SMS networks. iMessage offers enhanced features such as read receipts, typing indicators, multimedia support (photos, videos, etc.), and end-to-end encryption for privacy. These messages appear in blue bubbles in the Messages app.
2. Group message: There are three types of group messages that you might see: group iMessage, group MMS, and group SMS. The Messages app automatically chooses the type of group message to send based on settings, network connection, and carrier plan. For example:
   1. 1. If you and your recipients are using Apple devices and iMessage is turned on, then the group message is sent as an iMessage. If you can't turn on or sign in to iMessage or FaceTime - Apple ... If you can't turn on or sign in to iMessage or FaceTime - Apple ...
3. If you send a group message to people who are on Android, then the message is sent as an MMS or SMS message. Check if you have an SMS plan enabled by your carrier for the SIM/eSIM that you use on your device. Apple Inc does not provide SMS services. You need to contact your Carrier to enable SMS and/or MMS.
4. Carrier (Cellular Service Provider)
   1. SMS (Short Message Service): SMS is the traditional text message format used on all mobile phones. It is limited to 160 characters and is sent over the cellular network. SMS does not require an internet connection, but it also lacks features like media sharing or real-time typing indicators. Messages sent via SMS appear in green bubbles on an iPhone.
   2. MMS (Multimedia Messaging Service): MMS allows users to send multimedia content, like images, videos, and audio, along with text messages. Unlike SMS, MMS requires a data connection. MMS messages also appear in green bubbles on iPhones, as they are sent over the cellular network instead of Apple's iMessage system.
   3. RCS (Rich Communication Services): RCS is a modern messaging protocol designed to replace SMS and MMS, offering features similar to iMessage, such as high-quality media sharing, read receipts, typing indicators, and more. It is supported by some Android phones and mobile carriers, though not yet universally available. RCS can be used in messaging apps that support it, but it is not natively integrated into Apple's Messages app at the moment.
5. Third-Party Text Messaging Apps: In addition to iMessage, iPhone users can install and use various third-party messaging apps such as WhatsApp, Facebook Messenger, Telegram, Signal, and more. These apps typically use internet connections (Wi-Fi or data) to send messages and offer additional features like voice and video calls, group chats, file sharing, and security features (like end-to-end encryption). These messages are usually separate from iMessages and are managed within their app.

Each of these types of messages may have different behaviors, settings, and limitations depending on the network, device, or app being used.

What Call? On an iPhone, you can make and receive various types of calls. Here are the different types:

1. These are standard voice calls made over the cellular network. They utilize your carrier's voice network to connect you with other phone numbers. Allow phone calls on your iPad, iPod touch, and Mac
2. FaceTime Audio allows you to make voice calls over Wi-Fi or cellular data using your internet connection. It provides higher audio quality compared to traditional cellular calls.
3. FaceTime Video enables you to have video calls with other FaceTime users. It uses the front or rear camera on your iPhone to transmit live video during the call. Use FaceTime with your iPhone or iPad - Apple Support (IN)
4. VoIP (Voice over Internet Protocol) calls use internet connectivity to make phone calls. Apps like Skype, WhatsApp, Viber, and Google Hangouts utilize this technology, allowing you to make voice and video calls over the Internet.
5. Some carriers support Wi-Fi calling, which allows you to make and receive calls over a Wi-Fi network instead of relying solely on cellular coverage. This can be useful in areas with weak cellular reception. Make a call with Wi-Fi Calling - Apple Support (IN)
6. The App Store offers numerous calling apps that utilize different technologies. These apps can provide additional features and options for making calls, such as international calling, call recording, and more.

It's important to note that the availability of certain call types may depend on your iPhone model, iOS version, and carrier.
