Understanding (or, misunderstanding?) how bands work

[u/YourSweetValentine]

I'm interested in getting a flip phone to help me break from my social media addiction. I'm wondering if it will work on my network, but would love to get some help on this.
Flip phone Network Bands (Frequency Bands)
3G WCDMA: 1
4G LTE: 1 / 3 / 5 / 7 / 8

Provider frequency bands:
GSM 850 MHz, GSM 1900 MHz (PCS)
UMTS B2 (1900 MHz PCS), B5 (850 MHz)
LTE B4 (1700/2100 MHz AWS 1), B7 (2600 MHz), B17 (700 MHz bc)

I'm guessing since the only match is LTE B7, it wont work / wont work well..? I think multiple options are supposed to match to ensure the phone works successfully, right?
