Their service is BYOD (Bring Your Own Device) only - they do not sell any equipment. Any device that is compatible with the AT&T network should work on i3 Mobile, as should unlocked T-Mobile phones. If you have a question about whether or not your current phone will work on their network, they have a Device Compatibility Checker on their site.
All of their phone plans offer unlimited talk and text in the U.S., Mexico and Canada, as well as to/from Mexico and Canada. They offer both consumer and business plans.
Video streaming is provided at a minimum resolution of 480p - but could be higher.
While their plans are unlimited, they do have some of the usual language around "reasonable use."
Including "Unlimited services may not be used for conference calling, 3-way calling, call forwarding, monitoring services, data transmissions, transmission of broadcasts, transmission of recorded material, or other connections that do not consist of uninterrupted live dialog between two individuals."
Also, it should be noted that they will terminate service if a data device (i.e. a hotspot) is activated on a phone plan. Data devices must be activated on data plans only.
From their site:
