You can share one phone's mobile data with another phone by turning on its hotspot feature
Mobile hotspot is a built-in feature on most smartphones that turns your phone into a small wireless router. When you enable it, your phone broadcasts a Wi-Fi signal that other devices — including another phone — can connect to and use for internet access. The phone providing the hotspot uses its cellular data plan to power the connection, so the data counts against that plan's monthly limit, not the connecting phone's plan.
The process is straightforward: enable hotspot on the phone with the data connection, find that phone's hotspot name in the Wi-Fi list on the second phone, enter the password, and connect. Both phones need to be charged enough to stay on during use, and the phone providing hotspot will drain its battery faster than normal.
Key Takeaways
- Hotspot is a feature built into Android and iPhone that lets you share one phone's cellular data with another phone over Wi-Fi.
- The phone providing hotspot must have an active cellular data plan, and all data used by connected devices counts against that plan's monthly limit.
- You turn on hotspot in your phone's settings, then connect the second phone to it the same way you would connect to any other Wi-Fi network.
- The phone providing hotspot will use battery much faster than normal, so keep it plugged in if you plan to use it for more than a few minutes.
- Some carriers charge an extra monthly fee for hotspot use, while others include it free with certain plans — check your carrier's terms.
How to enable hotspot on iPhone
On iPhone, hotspot is called Personal Hotspot. Open Settings, then tap Cellular. Scroll down and tap Personal Hotspot. Toggle the switch to turn it on. Your phone will show a blue bar at the top of the screen when Personal Hotspot is active.
The first time you enable it, your phone generates a Wi-Fi password automatically. You can see this password in the Personal Hotspot settings — write it down or screenshot it so you have it ready when you connect the second phone. If you want to change the password to something easier to remember, tap Wi-Fi Password in the same menu and type a new one.
If you do not see the Personal Hotspot option, your carrier may not support it on your plan, or you may need to contact your carrier to add it. Some carriers include it free; others charge a monthly fee or require a specific plan tier.
How to enable hotspot on Android
On Android, the process varies slightly by phone brand, but the general path is the same. Open Settings, then look for a section called Network, Connections, or Mobile Network. Tap Hotspot or Tethering (some phones call it Mobile Hotspot or Portable Hotspot). Toggle the switch to turn it on.
Android also generates a Wi-Fi network name and password automatically. You can usually change both in the hotspot settings — look for an option like Configure Hotspot or Set Up Hotspot. Write down or screenshot the network name and password before you try to connect the second phone.
If you cannot find the hotspot setting, check your phone's manual or search the manufacturer's support site for your specific model. Some older Android phones or phones from certain carriers may have the setting in a different location.
How to connect the second phone to the hotspot
On the phone that will use the hotspot, open Settings and go to Wi-Fi. You should see the hotspot network name appear in the list of available networks — it will be the name you saw in the hotspot settings on the first phone. Tap it to select it.
Your phone will ask for the Wi-Fi password. Enter the password exactly as it appears in the hotspot settings on the first phone — passwords are case-sensitive, so uppercase and lowercase letters matter. Once you enter the correct password, the second phone will connect and show a Wi-Fi icon in the status bar.
The second phone can now use the internet through the first phone's cellular data. Open a browser or app and test the connection to make sure it is working. If the connection is slow, move the phones closer together — Wi-Fi range is usually 30 to 50 feet in open space, less through walls.
Data usage and monthly limits
All data used by the second phone counts toward the first phone's monthly data limit. If the first phone has a plan with 10 gigabytes per month and you use 3 gigabytes through hotspot, the first phone will have 7 gigabytes left. This is true even though the second phone may have its own separate data plan — hotspot bypasses the second phone's plan entirely.
Some activities use data much faster than others. Streaming video uses the most data — one hour of standard-definition video can use 1 to 2 gigabytes. Browsing websites, checking email, and using social media use much less. If you are concerned about hitting your limit, turn off hotspot when you are not actively using it, and avoid video streaming through hotspot.
Your carrier will show hotspot data usage in your account the same way it shows regular cellular data usage. Check your carrier's app or website to see how much data you have used so far this month.
Battery drain and keeping the hotspot phone charged
The phone providing hotspot will lose battery much faster than normal — sometimes two to three times faster, depending on how many devices are connected and how much data is being used. If you plan to use hotspot for more than 15 or 20 minutes, plug the first phone into a charger.
If you cannot plug it in, enable Battery Saver or Low Power Mode on the first phone to slow the battery drain. This will reduce the speed of the hotspot connection slightly, but it will keep the phone running longer. On iPhone, swipe down from the top right and tap the battery icon. On Android, go to Settings, Battery, and turn on Battery Saver.
If the first phone's battery runs out while the second phone is connected, the hotspot will turn off and the second phone will lose internet access. Keep an eye on the first phone's battery level, especially if you are using hotspot away from a charger.
Carrier fees and plan restrictions
Some carriers include hotspot use free with all plans. Others charge an extra monthly fee — typically $10 to $20 — or only include it with certain plan tiers. A few carriers limit how much data you can use through hotspot each month, even if your overall plan has more data available.
Check your carrier's website or call customer service to find out whether hotspot is included in your plan and whether there are any restrictions. If your carrier charges a fee and you do not want to pay it, you can turn off hotspot and straightforward not use it — the feature will not set up unless you manually turn it on.
If you switch carriers or change your plan, ask the new carrier about hotspot before you sign up. The cost and availability vary widely, and it may be a factor in which plan you choose.
Frequently Asked Questions
Can I connect more than one phone to the same hotspot?
Yes. Most phones can connect up to 5 to 10 devices to their hotspot at once, though the exact number depends on your phone model and carrier. Each additional device will slow the connection slightly and use more battery on the hotspot phone. Check your phone's hotspot settings to see the maximum number of devices allowed.
What if the second phone cannot find the hotspot network?
Make sure the first phone's hotspot is actually turned on — check the settings to confirm the toggle is switched to on. If it is on, try turning it off and back on again. Move the phones closer together and make sure there are no thick walls between them. If the second phone still cannot see the network, restart both phones and try again.
Why is the hotspot connection very slow?
Slow hotspot speed usually means the first phone has a weak cellular signal. Move to a location with better signal — look for more bars in the cellular signal indicator. If the signal is still weak, the hotspot will be slow no matter what you do. You can also try moving the phones closer together, as Wi-Fi range can be limited.
Does hotspot work if the first phone does not have Wi-Fi?
Yes. Hotspot uses the phone's cellular data connection, not Wi-Fi. The first phone does not need to be connected to Wi-Fi for hotspot to work. The second phone connects to the first phone's hotspot over Wi-Fi, but the first phone is pulling data from the cellular network.
Can I use hotspot if my data plan is paused or out of data?
No. If your data plan has run out of data for the month or is paused, hotspot will not work. The first phone needs an active cellular data connection to share. If you have reached your monthly limit, you can usually buy extra data from your carrier, or wait until your plan resets next month.
