Hi there! For buying a phone and paying monthly, I'd recommend looking at the Samsung Galaxy S22 Ultra 128GB, 256GB or 512GB models. All major mobile carriers offer installment/contract plans so you can pay off the phone in affordable monthly payments over 24 months instead of the full upfront cost. The Ultra is Samsung's top of the line flagship for 2022 with its powerful performance, large vibrant screen and advanced camera capabilities. Let me know if you need any help contacting carriers to find the best monthly plan options for your budget. I'm afraid my search results didn't include specific carrier offers, but they should be able to provide all the payment details.
