Jane says her iPhone 8 gives her a NO SIM warning every few days and she has to take out the SIM and put it back in. But then it'll do it a few days later. Leo says that chances are the SIM is warped and doesn't sit flat in the slot. But the good news is she can request a new SIM from the carrier. Just ask them.
Rick wants to know the difference between dual sim standby phones and dual sim active phones. Leo says that most modern phones now support dual sim active, enabling you to switch between two lines with one phone. Most use two SIMS, but other phones, like the iPhone 11, offers an eSIM option, where you have one actual SIM, but an electronic SIM for another phone line. Dual Standby means both connect to their networks, but independently.
John is going to Prague soon for a vacation. He's looking for his data options while there and how to translate the language he will see. Leo says that prepaidwithdata.wikia.com is a great place to find what local sims are available. Is there a pro/con of using a SIM vs. a hotspot? Leo says absolutely. Go for the hotspot. A local SIM will change his phone number while in the country, and as such, nobody can reach him unless they have his new number.
Neil bought a new iPhone and wants to give his old iPhone X to a family member. How can he transfer the phone and number to them? Leo says that since Neil has Verizon, he has to have the phone unlocked, and they will do it with a request. But it's as simple as taking the SIM out: you'll want it with your new phone anyway. Then, you'll also want to erase the phone and restore it back to the factory settings.
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.
