iPhone 7Plus - recently used hotspot connection very easily. Then the password automatically changed every time I went to turn on Personal Hotspot. As far as I am aware, nothing changed from previous settings. Could anyone assist please? I have followed all Apple Support procedures and looked at updates both on my iPhone and laptops (one is Mac the other Windows) I simply cannot link anything unless with USB now to my hotspot????

TIA

Hotspot is your phone carrier feature, contact them.
