Wi-Fi calling only works on unlocked iPhones, unlocked Google Pixel phones, and AT&T branded phones. Unlocked Samsung phones are not compatible with Wi-Fi calling at this time.
AT&T is one of the leading providers of wireless service in the United States. They were first started in 2000 as a spin off of Cingular Wireless. AT&T builds and operates their own nationwide network in the United States. They offer premium wireless service at more expensive rates, but with robust coverage and fast data speeds the premium rates are worth it for certain users.
AT&T Prepaid, formerly known as AT&T GoPhone, offers AT&T's robust network coverage and performance at more affordable price points than AT&T postpaid. However, some AT&T Prepaid plans lack certain features. Wi-Fi calling isn't available on the $55 prepaid plan, and the international Day Pass and Passport add-ons are not available for any prepaid plans if you want to use your phone while traveling.
Check each plan for more details on the supported features that are available.
AT&T Prepaid offers family discounts. However, the family discounts of the postpaid plans make those almost worth considering over AT&T Prepaid.
AT&T builds and operates their own network in the United States. It is one of the most robust networks in the country.
AT&T Prepaid supports unlimited texting to over 100 countries. Unlimited talk and text to Mexico and Canada is also supported.
AT&T Prepaid offers talk, text, and data roaming to Mexico and Canada with their prepaid plans. Unfortunately no other international coverage is supported at this time.

You can contact AT&T customer support at their general support phone number: 1 (800) 288-2020.
AT&T Prepaid offers a hotspot add-on for their $45 plan (price listed with auto-pay, the full plan price is $65 per month)
Add mobile hotspot data to AT&T Prepaid's $45 plan at a rate of $10 per 5GB. It's honestly better to upgrade to AT&T Prepaid's $55 plan ($75 full price), because for $10 extra you get 22GB of priority data and 10GB of hotspot data.
