Home internet using phone

Any hexbears do this? I need to get rid of shitcastinfinitynbcuniversalmeglocorp asap and I narrowed it down to two choices:

1. Minternet mint mobile home internet & mint mobile phone plan. I can get Minternet router for 6/12 months prepaid and mint mobile unlimited plan for my iphone for $45 to $50 month for a year. I am planning on moving next year hopefully by June and I'm not sure where yet and I don't know if it will roam or if I have coverage after the move. It's the cheapest home internet and phone plan but prepaid and might not work where I'm moving.
2. Google Fi. I can get a Pixel 9A and two years of unlimited internet which is actually 50 Gb phone data and 50 Gb hot spot data for the same upfront cash outlay as Mint mobile and then $55 month for two years. I need to keep it for two years for the $55/month because google cyber monday deal is cost of the phone($400) and $240 off google fi for two years. The $640 deal is spread out over 24 months with $27 off a month. The $55 month google fi plan over two years includes the cost of the pixel 9A but have to keep google fi for two years to get that price.

No matter what scheme I come up with internet access and phone will come out to $50 +/- $10 so this isn't a financial question. What I am wondering is if I can use a pixel 9A to stream 50Gb month and use it as my primary phone. I see a lot of people saying the battery will go bad since I am using a pixel as a home router. Mint mobile solves home internet and phone for a year and no 50Gb home internet cap and google fi solves home internet and phone for two years with 50Gb home internet cap. The reason I'm posting this in Technology is I need to determine if pixel will last two years as a router and main phone. Also muh eyes are bad and I can only use phone for bank/bills/email/sms but cannot surf internet without using laptop or desktop so hotspot/tethering is a must and because I live in a capitalist society I have to make a decision TODAY (cyber monday).
