Francis' family all have different smartphones, and they are having a hard time with calls and text messages, no matter what phones they are using. They are all updated phones, all on T-Mobile, and they don't really know what to do. Leo says that the issue is likely cellphone towers and coverage in her area. Maybe a few towers are down for maintenance? Or were the towers shut down when T-Mobile merged with Sprint? Since that's when the problem started, it's likely the merger is a main culprit. It may also be time to change carriers.
Julie's mom in Buffalo has very poor cellular service. They've tried just about everything. Should she try Verizon? Leo says that it's best to see what the local coverage is. T-Mobile, for instance, is very good in cities, but not in rural areas. Ask her neighbors. Verizon may be better, but they're more expensive. Spectrum, though, uses Verizon's network. In fact, check with MVNOs. They buy cell service in bulk and resell it.
John has issues with coverage in his home town. Leo says that the irony is that AT&T is considered to have total universal coverage, but that doesn't seem to be the case entirely. Leo says to go to the carrier he's with and ask them for a FemToCel. If they want to keep his business, they'll give him one for free. With it, it will route his calls over the internet for cell service to his phone.
