Karen is finding that her Virgin Mobile service is just terrible. Leo says that's because Virgin uses Sprint and their coverage is pretty spotty. There's no carrier that works everywhere, unfortunately. Karen should make sure to go with a service that works where she travels the most and where she lives. That's likely going to be AT&T or Verizon.
Evan bought an iPhone 6s Plus on the first day. He hears there's a different phone for AT&T, though. Leo says that's true. The AT&T iPhone is different, but only in that it has an extra band. Leo says that's not a bad thing as the AT&T model has a lower frequency to pass through walls. But can it work with other carriers? Leo says that nobody has really addressed it, but with all the bands that it has, it's a question an RF engineer might be able to answer. Leo's betting if he put the SIM in it, it should work in most cases.
Jason has been having issues with his ISP because they've changed his internet to UVerse and disconnected his lifeline. Leo says that Jason should file a report with the California public utilities commission, because that's illegal. If he's disabled, as Jason is, then he has even more reason under the Americans with Disabilities Act. Contact TURN, The Utility Reform Network. They are a non profit consumer advocate organization. They'll be able to help.
Sean is having issues with his iPhone. It's demanding he activate it again. His carrier is AT&T. Leo's wondering if the SIM card has come loose, gone bad, or fallen out. Leo says to go to AT&T and ask them to replace the SIM.
Leo says there's an app called Pushbullet that will deliver phone notifications to his computer through the web. Ryan needs something that direct his voicemails to his email, though. He has tried Google Voice, and that works for voicemail but not necessarily text messages, because those would default to iMessages on his iPhone. If he can get people to text him to his Google Voice number, then he can check those texts on the web.
Mark still has the AT&T Unlimited data plan, but it's so expensive. Should he just keep it or downgrade to a smaller, more limited plan. Leo says that the CEO of AT&T is on record sharing his regret that he ever offered that option. But they've now incentivized enough to get people to give it up. It may be you can save money by giving it up, but they don't want to make it easy to give you the best deal. Leo advises going to the AT&T store and asking a salesmen to walk you through the options because you're thinking of jumping ship.
Sharon has a Verizon cellphone but wants to get her old AT&T iPhone 4S added to the plan. Verizon said they can't add that phone to their network, though. Leo says back then, AT&T and Verizon phones only worked with either GSM or CDMA technology. If the phone was newer, like an iPhone 5S or iPhone 6, she could do it because they are called "world phones." She may need to unlock it. But the 4S predates the era of iPhone world phones, and it won't work.
Soup is ready to get his first smartphone. Leo says the number one thing to decide is which carrier he wants. Then choose the phone from there. He'll want the carrier that offers the best coverage in his area. Service-wise, they're all horrible in some way. But coverage is better for some than others.
