Do you need a smartphone? Do you need a phone of your own? I can pretty much guarantee that your wife wants a mobile phone of her own, but it is up to her to decide whether or not she needs a smartphone.
Otherwise it is situational. Not everyone needs to carry around a phone, although most people now want to. Not everybody needs to be carrying around a powerful computer in their pocket, although most enjoy playing it.
For about 20 years before my wife died, she had the only mobile phone in the family, I was either with her, or at work, where personal mobile phones were still banned as a detraction and security risk.
When I retired and started going places aone while she was at work, she made me get a Tracfone so that she could call me when she needed help or wanted to issue instructions. That didn't work out so well because I wasn't used to carrying a phone around and usually left it at home.
My older daughter's four member family is a four-smartphone, four tablet family. My younger daughter's family of three is a two non-smart, one tablet family, although the four year old would probably like to have his own smartphone and/or tablet, as he is the most fluent in the use of these devices, whether iOS or Android. But that doesn't make him ready to be carrying one around.
If you think you want an smartphone to play with, and your wife wants one, you need two. They don't share very well. That's also why, in many families, each computer user has their own computer, or tablet, if that's the direction they've gone. In a lot of families each also has their own TV.
But you have to figure out your own situation.
Now, if you have multiple spouses, they each get their own phone, but you don't put them on the same shared plan. That's how my dummy brother in law got caught by his first wife (the second one knew what was going on).
