Michael has a Samsung Galaxy S4 and is looking to upgrade. He wants a phone that isn't made in China and doesn't have a lot of junk on it. Leo says that not being made in China is the challenge, although Samsung's phones are made in South Korea. There are many good mid-range phones at the $500 level. Google's Pixel 4a is an excellent, "clean" phone with no extra stuff. But it is made in China. But at $349, you can't beat the price.
Lex and his wife have identical Samsung international phones. But when they travel to Richmond, VA, his wife's phone stops taking and receiving calls. What gives? Leo says it's because he bought an international phone. Each carrier supports different radios. So he can travel to somewhere in the US and those phones won't be supported. Leo recommends going to GSMArena, enter the model number, and it will tell what radios it supports. But his works while her phone doesn't. Leo says it's possible he doesn't have the exact same model, but very close. It could also be a configuration issue.
