Your T-Mobile hotspot is not working for one of two reasons: your plan does not include Mobile Hotspot, or your phone is outside 5G or 4G LTE coverage. T-Mobile requires both a qualifying plan and a 5G or 4G LTE signal for the hotspot feature to function, so checking these two things first will resolve the majority of issues.
Why your T-Mobile hotspot not working: the 2 most common reasons
The most common verified reasons your T-Mobile hotspot is not working are that your smartphone plan does not include Mobile Hotspot, or your device is outside 5G or 4G LTE coverage. T-Mobile states that Mobile Hotspot requires a plan that includes the feature and that you be on a 5G or 4G LTE network. If you are not on a qualifying plan or are in an area without that coverage, the hotspot will not work. T-Mobile says Mobile Hotspot lets you share your device’s internet connection with up to 10 Wi‑Fi-enabled devices.
Check your plan includes Mobile Hotspot
T-Mobile’s smartphone hotspot feature is called Mobile Hotspot, Wi‑Fi Sharing, or tethering. Most T-Mobile plans include Mobile Hotspot, but not all do. To confirm, check your plan details in your T-Mobile account online or in the T-Mobile app. If your plan does not include Mobile Hotspot, you will need to switch to a plan that does before the feature will work.
Make sure you're on 5G or 4G LTE coverage
T-Mobile says Mobile Hotspot requires 5G or 4G LTE coverage. If you are in an area with only slower 3G or no signal, the hotspot will not function. Move to a location with stronger 5G or 4G LTE reception, such as near a window or outside, and check the signal indicator on your phone before trying again.
Turn on Mobile Hotspot the right way
On an iPhone, go to Settings > Personal Hotspot and turn on Allow Others to Join. On Android, the controls are under the device’s Connections & Network menu. For stock Android, the path is Settings > Network & Internet > Hotspot & tethering > Wi‑Fi hotspot. On Samsung devices, use Settings > Connections > Mobile Hotspot and Tethering > Mobile Hotspot. T-Mobile’s help articles direct you to the Connections & Network menu for model-specific steps.
Verify your hotspot name and password
On iPhone, the hotspot name appears under To Connect Using Wi‑Fi and the password is next to Wi‑Fi Password in Settings > Personal Hotspot. On Android, the SSID and password are visible in the hotspot settings screen. On the device that needs to connect, go to Settings > Wi‑Fi (or Settings > Wi‑Fi settings on Android), select the hotspot’s SSID, and enter the password. If the connecting device shows the wrong network name or rejects the password, double-check both on the hotspot phone.
Restart your phone and the connecting device
A simple restart clears temporary glitches that can prevent hotspot connections. Turn off both the hotspot phone and the device trying to connect, wait a few seconds, then turn them back on. After restarting, turn on Mobile Hotspot again and attempt to connect.
Check for T-Mobile network outages
A broader network outage in your area can prevent hotspot from working even if your plan and signal are fine. Visit T-Mobile’s website or contact customer support to check for known outages. If an outage is reported, wait until service is restored before troubleshooting further.
When to contact T-Mobile support
If you have verified your plan includes Mobile Hotspot, confirmed you are on 5G or 4G LTE coverage, turned on the hotspot correctly, checked the SSID and password, restarted both devices, and ruled out network outages, the next step is T-Mobile’s dedicated Mobile HotSpot troubleshooting page for supported T-Mobile phones and tablets. That page covers hotspot basics and troubleshooting for your specific device. T-Mobile’s hotspot guidance says the feature works on supported T-Mobile phones and tablets and points users to device-specific instructions. If the issue persists, contact T-Mobile customer service for further assistance.
Frequently Asked Questions
How many devices can connect to my T-Mobile hotspot at the same time?
Up to 10 devices can connect to your T-Mobile hotspot at the same time.
Can I use my T-Mobile hotspot while roaming?
Hotspot functionality while roaming depends on your specific plan and the roaming partner’s network. T-Mobile’s hotspot feature requires 5G or 4G LTE coverage, and roaming networks may not support it or may apply separate data limits.
Why is my hotspot connection slow even with full signal?
Slow speeds can occur if many devices are connected, T-Mobile allows up to 10 devices, or if you have exceeded your plan’s high-speed data allotment. Check your data usage and disconnect unused devices to improve performance.
Does T-Mobile charge extra for Mobile Hotspot?
Most T-Mobile plans include Mobile Hotspot at no additional cost, but some legacy or limited plans may not. Verify your plan details in your account to see if hotspot is included or if an add-on is needed.
Can I change the Wi-Fi password of my T-Mobile hotspot?
Yes. On iPhone, go to Settings > Personal Hotspot > Wi‑Fi Password. On Android, the password can be changed in the hotspot settings under the Connections & Network menu. For a dedicated hotspot device, access the device’s settings menu through its web interface or admin page to update the Wi-Fi password. The connecting device will need to re-enter the new password.
