Use Speedify's Peer-to-Peer Cellular Sharing Feature
When you need internet access on the go, Wi-Fi tethering iPhone capabilities through Personal Hotspot can be a lifesaver.
Whether you're working remotely, traveling, or dealing with unreliable broadband, your iPhone can turn into a powerful mobile router. But you're still vulnerable when it comes to cellular outages from your provider or network congestion.
Learn how to overcome these issues and get fast and uninterrupted Internet using your iPhone's Personal Hotspot and Speedify, the only app that helps you use all available Internet connections at once.
Use Speedify to increase your bandwidth: Combine internet connection sources like WiFi, 4G, 5G, & Starlink together

Combine multiple internet connections to fix slow Internet
Speedify is the only app that seamlessly combines all of your connections, including WiFi, 4G, 5G, Ethernet, and Starlink, into one stronger connection to keep you online and secure.
In most cases, Speedify will automatically detect and start using any available Internet connections on your device while intelligently distributing your online traffic between them for optimal performance. If you need help we have quick start guides available for most common set ups.

Combine personal hotspots for better bandwidth and signal strength
Speedify's Pair & Share is a feature that enables you to connect to multiple hotspots at the same time and wirelessly share LTE, 4G, and 5G cellular connections back and forth between multiple Speedify users on the same local network to create a faster, more reliable connection for everyone.
For the first time, it's possible to share cellular data between multiple devices, including PCs, Macs, iPhones and Androids. Use multiple phones as hotspots for internet access and get increased bandwidth and mobile failover for all paired devices.
How to Enable Wi-Fi Tethering (Personal Hotspot) on Your iPhone
Setting up WiFi tethering iPhone functionality is straightforward:
- Navigate to Settings > Personal Hotspot
- Toggle Allow Others to Join to enable the feature
- Set a strong Wi-Fi password for security
- Connect your other devices to the Personal Hotspot.
Your iPhone will now broadcast a Wi-Fi network that other devices can join, sharing your cellular data connection.
How iPhone Personal Hotspot Performance Is Influenced by Other Factors
The performance of your WiFi tethering iPhone setup depends on several factors:
- Your cellular signal strength directly impacts speed and stability – a strong 5G or LTE connection will deliver superior results compared to weaker signals.
- Location matters significantly, as network congestion in dense urban areas can affect throughput.
- Battery consumption increases substantially when using Personal Hotspot, as your iPhone simultaneously manages cellular data reception and Wi-Fi broadcasting. Expect 30-50% faster battery drain during active tethering sessions.
Wi-Fi Tethering iPhone Limitations

Using the iPhone's Personal Hotspot comes with important constraints. So if you get slow internet speeds when connected to your iPhone's Personal Hotspot, here are some potential causes for this.
Most cellular carriers impose data throttling after specific usage thresholds, potentially reducing speeds significantly. Some plans limit hotspot data separately from regular mobile data, so verify your carrier's policies.

Heat generation is another concern during extended tethering sessions. iPhones may throttle performance or temporarily disable features to prevent overheating, particularly in warm environments or when charging simultaneously.
The number of connected devices affects performance. While iPhones support multiple connections, each additional device reduces available bandwidth per user.
How to Maximize iPhone Personal Hotspot Performance
Here are some ideas on how to optimize the performance when doing Wi-Fi tethering on your iPhone.
- Position your device in areas with strong cellular reception. Elevated locations away from interference sources typically provide better signal quality.
- Keep your iPhone plugged in during extended sessions to maintain battery life, but monitor temperature levels. If the device becomes excessively warm, temporarily disable hotspot functionality to allow cooling.
- Regularly monitor data usage through Settings > Cellular to avoid unexpected overage charges or throttling. Consider upgrading to unlimited or high-data plans if you frequently rely on tethering.
- Update to the latest iOS version to ensure optimal performance and security patches for Personal Hotspot functionality.
Speedify Helps Enhance iPhone Personal Hotspot
For users requiring maximum reliability and performance from their Wi-Fi tethering iPhone setup, Speedify offers a proven solution. It allows you to combine multiple internet connections – including your iPhone's hotspot, nearby Wi-Fi networks, and even additional cellular connections – creating a faster, more stable internet experience.
Speedify's channel bonding technology automatically switches between available connections, reducing interruptions and maximizing bandwidth. The service is particularly valuable for professionals who depend on consistent connectivity for video calls, file uploads, or other bandwidth-intensive tasks.
When it comes to combining multiple cellular connections at once, Speedify provides a dedicated peer-to-peer cellular sharing functionality, called Pair & Share. With this, you can take your Personal Hotspot at the next level and easily share and combine cellular connections between devices to create a faster, more reliable connection for everyone.
It works like a turbocharged personal hotspot: instead of just one device sharing its connection with others, once paired, all devices can share and receive each other's connections simultaneously via two-way sharing of cellular data.
This is a great way to augment Wi-Fi tethering on your iPhone. You get faster, more reliable Internet for sharing from the field, calling from the commute, streaming from the live event or simply enjoying the best connectivity you can get anywhere.
