Select your phone below
1. Always use control centre to enable Personal Hotspot
We know, you can turn it on from Settings > Personal Hotspot too, but that approach can hide the cause of your problem.
When you enable Personal Hotspot from the Settings > Personal Hotspot panel, the icon will turn green and it'll look like it's turned on. However, if you have Wi-Fi turned off on your phone there's no error or any other visible sign that Hotspot isn't actually enabled at all.
Opening Control Centre
Swipe up from the bottom of the screen to open Control Centre if you're on an iPhone that has a home button (iPhone 5s, 6, 7, 8) - or swipe down from the right side of the screen if you don't have a home button (iPhone X, XS, XR, 11).
Then tap and hold on the network stack (top left corner) until you see all six icons above.
2. Check the state of the Wi-Fi button
The Wi-Fi button should be either white (indicating that the Wi-Fi hardware is enabled, but it's not trying to join any nearby Wi-Fi networks) or blue which means it's either connected to a Wi-Fi network, or is searching for one.
If the button is transparent like the image on the right and it says "Off" below the button, you need to tap the Wi-Fi button to turn it on.
3. Enable Personal Hotspot
Tap the Personal Hotspot button. It will turn green and show "Discoverable" until the terminal connects, when that will change to "1 Connection".
1. Ensure that Mobile Hotspot is turned on
When you first enter the connections menu you will see Mobile Hotspot and Tethering. If you tap on this it will take you to another menu with Mobile Hotspot, with a button next to it to turn it on. Normally when you tap this button it will enable hotspot, however, there is another button you may need to turn on. From the same menu if you click on the word Mobile Hotspot you will be taken to a new menu with another an On button. Turn it on here to enable Hotspot.
2. Ensure Allowed Devices is switched off
As a security measure, Android phones have a setting which prevents devices from joining a mobile hotspot unless they are allowed. This will prevent the VeriFone vx690 from joining the hotspot network. To turn it off navigate through settings > connections > mobile hotspot and tethering > mobile hotspot. In the top left corner tap the three vertical dots and then tap allowed devices. Ensure that allowed devices only is switched off before attempting to join the mobile hotspot.
