Sunana is going to Iceland and Europe later in the year, and will be driving all over. Leo says to make sure to bring a good camera. What about getting data for GPS and directions? Leo says the issue is international data roaming and it's punitively expensive. T-Mobile offers unlimited data overseas, but it's at the much slower speed of EDGE.
Dan's friend broke his phone, and he wanted to let him use his old Samsung Galaxy S4 phone. But Dan has Sprint and his friend has AT&T. Leo says he can try it by just slipping his old SIM into it. If it doesn't work, he'll know. If not, then it's time to get a new phone. But all new mobile devices are LTE now, so they can be used on other networks.
John randomly started getting the message that said "No SIM Card" on his iPad 2. He took it to AT&T and they gave him a new SIM card, but after a couple weeks, it started giving him that message again. Leo suspects the issue is something in the iPad, such as a short circuit that's actually frying SIM cards. It is an older iPad, and Leo suggests bringing it to the Apple store. But it most likely won't be a free repair. He shouldn't do anything to it himself -- he should have Apple look at it.
It might just be time to get a new one, though.
Zenia is going to Africa next month for a wedding, and she's worried about taking her phone. Leo says that the most expensive thing is data roaming. So the first thing she should do is go in the settings and turn off data roaming. That means she won't get any data while out of the country. However, T-Mobile, Zenia's carrier, offers unlimited international texting, affordable calling, and free EDGE data. It's not fast and she'll probably have to verify that the country she's in will support it. If not, she can always buy an international data roaming plan.
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.
Andre is taking his wife on a trip overseas and he wants to use his phone to post to Instagram and other social networks. Leo says that data oversees is a huge and expensive topic because people are wired everywhere, even when they travel. But he won't want to roam in another country because data roaming in obscenely expensive. The first thing he'll want to do it disable data roaming. He'd be surprised how many people come home to a data bill in the thousands and they hardly even used data.
Bob's wife is traveling to Italy on vacation and wants to know if she should bring her iPhone. Leo says that she could pay for an international data roaming plan. They're not cheap and the data caps are small, not to mention the cell call charges.
Another way is to turn off data roaming. She won't have data unless she has Wi-Fi access, like at her hotel. Some apps, like Google Maps, would allow her to cache data while away from Wi-Fi.
