David wants to know if he's secure surfing the internet on his mobile device. Leo says that nothing is unhackable, but LTE is encrypted and very secure. A phone can be hacked, even at the radio level, though. It's also possible for someone to spoof his SIM card. But it's too much work for the average hacker. It would have to be a state level attack in order to accomplish it. Wi-Fi is less secure, and if he's relying on WPA2 or any other Wi-Fi connection, it's possible to hack it. But that's not easy, either. Odds are, there's really not all that much to worry about.
Dana has a 3G smartphone with Verizon and hears they are going to turn off the towers soon. Leo says yes. The plan is to turn off all 3G towers within six months in favor of LTE. They're not even activating any 3G phones anymore. So the future is calling! Pity is, those phones still work as phones. It's a shame that they'll just end up being in a landfill.
Mike wants to know what he needs to use his iPad on Wi-Fi. Leo says that any iPad will work on Wi-Fi. If he has LTE, however, he could use it anywhere. But for Wi-Fi, a regular iPad will work just fine. Since Mike is traveling internationally, Leo recommends also getting a MiFi card, which he can put a local SIM in for Wi-Fi. But since Mike is in the US Virgin Islands, international data roaming won't be an issue. Leo recommends getting an AT&T carrier version of the iPad. Leo likes the iPad Mini for traveling.
Steve is looking for a motion activated security camera that can run on a cellular network. Leo says that all security cameras are motion activated these days. DropCam and Nest would be the natural choice, but they rely on Wi-Fi.
Leo recommends the Eagle Eye Nubo. It has 2G, 3G and LTE. It's also weather resistant. But he'll want to be sure that it is supported by his carrier. He'll have to get the SIM from them anyway.
Penny is going on a cruise to Alaska soon and needs to keep in daily contact with her business. Will she have issues? Leo says it depends on which cruise line she's going on. Royal Caribbean has decent internet, but most of them don't. It'll be really slow because it's by satellite, and it will also be expensive. With over 1,000 people wanting to stay in touch, it'll slow to a crawl unless she logs on in the middle of the night when everyone else is asleep.
Bill is going to be RVing full time and wants to be able to stream Netflix while on the road. Does he need a cell booster to get a better streaming signal? Leo says that LTE is in most areas and it's quite fast and consistent. Bill can pay extra for hotspotting and then stream to a Roku device.
Lucas does a lot of video streaming and gaming, but he's moving to a rural area and will have to find new high speed internet. What can he do? Leo says that rural internet access is a real issue here and Leo doesn't believe the FCC cares enough to make it happen. Satellite isn't the answer because it's got terrible latency and bandwidth caps. That being said, the best satellite provider is WildBlue's Exede. It's that or dialup.
Scott wants to know if the heart rate monitor is better in the new Apple Watch Series 3. Rich says it is. There are more sensors and additional data points, so he'll get a more accurate reading of his heart rate. The only thing the Apple Watch doesn't do is monitor sleep, but Apple is about to get into that, so stay tuned. It will also alert him if he has an elevated resting heart rate. So if he wants to better monitor his heart, the new Apple Watch Series 3 is the one to get. It's available now.
Gregory has an RV and wants to know if he should get satellite for it that will give him faster WiFi. Leo says he could, but it would cost him a lot of money and would be a hassle to re-position the dish often. The future is in LTE, and it's also more affordable. Often times it's faster than home internet as well. He can get a WiFi device and he will then have access to over five different devices. Leo recommends Google Fi because it has three different ISPs on the same device and switches to the one that is better. And he can pay as he goes with it.
Alan has had a bad experience with several cell providers and he doesn't know who to trust. T-Mobile shut down GSM, so he couldn't use his phone. He went to AT&T, and they gave him a data only contract, leaving him without the ability to call or get text messages. He also can't afford to buy a smartphone.
