Then tap Wi-Fi Password, and in the next screen, enter a password. On your iPhone (or cellular-enabled iPad), go to Settings > Personal Hotspot and enable the switch for Personal Hotspot. Double-check your plan, but if you won’t have to pay more to use tethering, here’s how to use it to solve Wi-Fi problems while on the road. If you have an “unlimited” plan, your carrier may throttle your bandwidth if you exceed some usage level because the carrier doesn’t want customers to use tethering for their primary Internet connections. Nowadays, however, most mobile phone plans don’t charge extra for tethering, as it’s often called. For a number of years, turning on iOS’s Personal Hotspot feature involved additional fees from your cellular carrier, which dissuaded many people from using it. If you’re like most Apple users, the solution is in your pocket or purse: your iPhone. And while you might be able to find a coffee shop with free public Wi-Fi, those networks may not be secure-a hacker on the same network could watch your unencrypted Internet traffic. It isn’t any better when you reach your destination, since many hotels charge usurious rates for Wi-Fi. Look in your Wi-Fi menu while sitting in an airport and you’ll see a bunch of networks, most of which require a password or won’t connect for other reasons.
Finding good Internet access for your Mac or Wi-Fi-only iPad while traveling can be maddening.
