A personal mobile hotspot lets a phone or cellular tablet share its mobile data connection with nearby devices. Those devices commonly connect over Wi-Fi; supported phones can also share the connection over USB or Bluetooth.
What does “personal mobile hotspot” mean?
It is a feature on a phone or cellular tablet that shares the device’s cellular internet connection so another device—such as a laptop, tablet, or second phone—can get online. Apple calls this feature “Personal Hotspot” and describes it as creating a temporary, portable Wi-Fi network from an iPhone or cellular iPad’s mobile data connection. Apple’s Personal Hotspot instructions explain how other devices connect.
In practical terms, the phone or tablet is the host, and the devices that join it use the host’s mobile data service. The host remains a regular multifunction device; turning on its hotspot does not turn it into a dedicated hotspot appliance.
Is a personal hotspot the same as tethering?
The terms overlap in everyday use, but their labels vary by platform. Apple uses “Personal Hotspot” for its iPhone feature. Google’s Android Help groups sharing a phone’s mobile data with another phone, tablet, or computer under “hotspot or tethering.” See Google’s Android hotspot and tethering instructions. The sources do not establish one universal definition that every device maker or carrier uses.

How can another device connect?
Wi-Fi is a common way to join a phone’s hotspot, but it is not the only method. Available options depend on the device and its instructions.
- Wi-Fi: The host phone creates a network that nearby devices can join.
- USB: A compatible cable can connect the phone to a computer for wired tethering.
- Bluetooth: Supported devices can share the connection over Bluetooth.
Apple documents Wi-Fi, USB, and Bluetooth connections for iPhone Personal Hotspot. Android Help lists those methods as common options and notes that some phones can also share a Wi-Fi connection. On iPhone, Personal Hotspot shares the phone’s cellular internet connection, not a Wi-Fi connection the iPhone itself received. These details are platform-specific; check your device’s instructions for its behavior. Apple’s iPhone user guide covers its connection options.

Is a phone hotspot different from a dedicated hotspot device?
Yes. A phone hotspot is a feature of a phone or cellular tablet that already has other functions. A dedicated mobile hotspot is separate equipment designed primarily to provide Wi-Fi through a commercial mobile wireless internet service. The FCC uses that description in the context of its E-Rate program; it is a program-specific definition, not a universal rule for every use of “hotspot.” See FCC 24-76 (2024).
If you are deciding between tethering from a phone and using a separate device, the relevant questions include whether your provider and plan support the service, how many devices you expect to connect, and whether you want to carry and manage a separate device. The cited sources do not establish universal price, speed, or battery-life differences.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What should you check with your carrier?
Hotspot availability and terms are not the same for every provider or plan. Apple says a provider must support Personal Hotspot, additional fees may apply, and the number of simultaneous connections depends on the provider and iPhone model. Google likewise notes that some carriers limit tethering or charge extra.
