The latest scam is to convince the phone company to transfer your mobile phone number to a new SIM. Cloud Hopper is the app that does this. Once that's accomplished, the bad guys can gain control of all your apps, including banking apps with 2 factor authentication through a SIMJACKED phone. That's what happened to Twitter founder Jack Dorsey. Leo says that what he recommends is contacting your mobile service and request they use a PIN to verify it's you when seeking to get a new SIM.
Doug has a mobile device through Straight Talk. But his internet access is terrible with his iPhone 5. He was told by Straight Talk that the iPhone 5 is being phased out and he'll have to get a new phone. Leo says that Apple has stopped supporting the iPhone 5 and it's likely Straight Talk is doing the same thing. So you should be able to take the SIM out and put it in the new one. If it doesn't work, then you can just get a new SIM card from Straight Talk.
Patrick bought a Samsung Galaxy S9 at Best Buy for Black Friday. Can he just drop his SIM card in or does he have to get it activated? Leo says he should just be able to drop his existing SIM into it and get started. Leo says that the FCC doesn't like carrier locks if the carrier isn't subsidizing the phone. So all he'll have to do is call the carrier and ask them to unlock it, if he needs to. But if he's a Verizon customer, it shouldn't be locked at all, and since he's not switching carriers, it should work if it uses the same SIM.
Kirk is going on vacation to the south pacific and needs an international plan for his phone. Leo says that T-Mobile started a free 2G-3G international data and texting plan and it has put pressure on other carriers to do the same. Leo always brings T-Mobile with him when he travels. Leo also recommends Google Fi because it uses various carriers. AT&T has a daily pass option, which is $10 a day. Verizon was the hardest to use overseas, but they've recently started the day pass like AT&T. Kirk should check with his carrier and see what they offer.
Joe is traveling to Asia and he wants to know if it's better to get an international data roaming plan or get a local SIM wherever he goes. He uses Verizon. Leo says that Verizon is the most international unfriendly mobile carrier. Sprint, AT&T, and T-Mobile have their own reasonable plans (especially T-Mobile that offers a free slow internet). Verizon has a $10 a day plan, though, which isn't bad, but it adds up. It's going to be the easiest way since he would have to have a different SIM for every country he visits, and his phone number will change with each new SIM card.
Cathy is going to Italy and wonders if Viber will be good for getting free phone calls. Leo says that Viber is like Skype in that it uses the internet to make a phone call. She can also use Facebook Messenger. The issue is that whoever she calls will have to use the same program on the other end, unless she spends money to allow it to make calls to any phone. She'll want to be sure she doesn't use her carrier's data while being out of the country. It'll cost her thousands. She can use Wi-Fi, though.
Tim is traveling and wants to know how he can save money on data charges. Leo advises going to prepaidwithdata.wikia.com and he'll find a list of countries and cellphone providers in those countries that offer SIMS, how much they are, and where he can get them. But he'll also want to know if his phone supports the traffic where he's going. Verizon was CDMA up until lately, when they transitioned to LTE world phone models. That means they have SIM cards.
Marie is traveling to Great Britain and is worried about data charges on her iPhone 6. Leo says that Marie can go into her phone's settings and turn off Data Roaming. That's where the real data costs will rear it's ugly head. Then she can just depend on local Wi-Fi. She can also download the maps and keep them in the phone so she won't have to worry about getting lost with no data.
Dianne's 81 year old mother's cell phone was deactivated and she needs a new phone. Dianne wants to know if she could use the AT&T SIM in her old phone with an "Obama Phone" from Verizon on the Lifeline Assistance program. Leo doesn't think that would work. If not much time had passed, there's a chance that she could have her old number ported over to Verizon. But Dianne says it's been about a month since the old phone was cancelled, so that would be unlikely.
Dan is ready for his first smartphone and is looking at the iPhone 6 Plus. Leo says that while he doesn't carry an iPhone, it's a great phone, especially for beginners. It's a good choice accessibility-wise as well. The large screen in the 6 Plus makes it really easy to see. But Leo warns that it may seem like clown shoes going from the 4" iPhone 5 screen.
