Owners of the latest Apple smartphones often face the need to provide internet access to other devices, whether it's a colleague's laptop at a cafe or a tablet while traveling. iPhone 15 Pro, thanks to its powerful processor and support for modern communication standards, copes with the task of creating an access point Wi-Fi better than previous models. However, the transition to a new connector USB-C and updates in the operating system iOS can introduce some confusion into the familiar setup process for those who have previously used models with a Lightning port.
Modem mode turns your smartphone into a full-fledged router, allowing you to connect up to several devices simultaneously. It's important to understand that the quality and speed of the connection Internet Directly depend on the quality of your cellular network signal and your carrier's data plan. In this article, we'll detail all the ways to activate this feature, answer frequently asked questions, and help resolve potential connection issues.
Before you begin setup, make sure your device has data enabled and the latest carrier profile installed. Starting with iOS 17, Maximize Compatibility is enabled by default on Pro models, which may impact the frequency band selection when connecting older devices. Let's move on to practical steps that will take no more than a couple of minutes of your time.
Basic modem setup
The first step to setting up a wireless network is to properly enable the feature in the system settings. You need to open the app Settings on the main screen of your iPhone 15 Pro. Depending on the version iOS Depending on your carrier's settings, the "Modem Mode" option may be located either directly in the top menu or hidden within the "Cellular" section. If you don't see this option, search for it in the settings by entering the appropriate query.
After entering the menu, you need to enable the "Allow Others" switch. The system may ask you to confirm enabling cellular data if it was previously disabled. This window displays the name of your future network and the password required to connect your devices. Password You can change it to a more complex or, conversely, simpler one for quick input, although it is better not to reduce security.
⚠️ Please note: Some mobile operators may block the tethering feature at the tariff level. If the internet on connected devices doesn't work after enabling this feature, please contact your provider's support team to clarify their data charges.
For quick activation without diving deep into the menu, you can use the Control Center. To do this, swipe down from the upper-right corner of the screen (where the battery indicator is located). Find the connection settings section, and press and hold the cellular data icon (or Wi-Fi icon) until the menu expands.

A cable solves this problem, allowing the phone to be used as a full-fledged modem for extended periods without the risk of battery drain.
☑️ Check before USB connection
Using Bluetooth to save power
Although this method is considered obsolete due to its low data transfer speed, in some situations it may be the only available option or a necessary solution to save battery life. Connection speed by Bluetooth It's significantly slower than Wi-Fi and USB, so you won't be able to watch videos or download large files, but it's perfectly adequate for email, messaging, or navigation.
To set up, you need to enable Bluetooth on both devices - iPhone 15 Pro and the receiving device (tablet, laptop, or other phone). After pairing the devices in the Bluetooth menu, select the iPhone as the network access point on the receiving device. The pairing process requires confirming a code on both screens to ensure a secure connection.
| Parameter | Wi-Fi | Bluetooth | USB cable |
|---|---|---|---|
| Speed | High | Low | Maximum |
| Energy consumption | High | Low | Charging your phone |
| Stability | Average | High | Maximum |
| Range | Up to 15-20 meters | Up to 10 meters | Cable length |
It's worth noting that when connecting via Bluetooth, your iPhone may not display the standard green bar at the top of the screen indicating tethering. Instead, the Bluetooth icon in the status bar will serve as the indicator. This can be confusing for inexperienced users, but the connection will still function correctly if all settings are correct.
Connecting Apple devices and Family Sharing
The Apple ecosystem offers a unique instant connection feature known as Family Sharing or simply automatic pairing. If you own multiple devices with one Apple ID (for example, iPad and Mac), then when you turn on the modem mode on Your iPhone 15 Pro will be visible to your other devices in the network list without the need to enter a password. This works through Handoff technology and requires Bluetooth and Wi-Fi to be enabled on both devices.
To set up Family Sharing, you need to add family members to the Family group via iCloud. After that, you can allow them to use your data plan without sharing your password. A list of family devices will appear in the Personal Hotspot settings, allowing you to see in real time who is connected and how much data they are using. This is an extremely useful feature for keeping track of expenses, especially if you have a limited data plan.
⚠️ Note: The automatic connection feature only works between devices in the same iCloud group or that have contacts in each other's address book. Connecting third-party devices (Android, Windows) requires a password.
Telecom operators typically don't differentiate between the types of connected devices, counting all outgoing traffic as the SIM card owner's internet usage. Therefore, keep an eye on your data usage if a family member decides to watch a movie in high definition.
Why doesn't my Mac automatically detect my iPhone?
For instant connection to work, both devices must have Bluetooth and Wi-Fi enabled, and both devices must be signed in to iCloud with the same Apple ID or added to each other's contacts. Also, make sure Personal Hotspot is not disabled in iCloud settings.
Solution and diagnostics
Despite a well-functioning system, users may encounter situations where tethering fails to activate or devices fail to detect the network. Often, the problem stems from faulty network settings or an outdated carrier profile. First, it's recommended to check for updates. iOS and carrier profiles, as Apple regularly releases patches that improve compatibility with different provider networks.
If software methods don't help, an effective solution is to reset network settings. This will return all Wi-Fi, Bluetooth, and cellular network settings to factory defaults.
