Patty is having issues with coverage in her area, and it's all of a sudden. Leo says that her carrier may have turned off a tower to do maintenance. But it may also be that Patty needs to go into the store and get an updated SIM card since they recently merged with Sprint and turned off that tower. So you need a new T-Mobile Sim. Patty should also consider changing carriers. Word is, that Verizon is better in her area. But it's also the most expensive.
