Ask whether equipment rental, installation, or activation costs apply.
Review data limits, contracts, promotional periods, and cancellation terms.
Check support hours and the expected installation or activation timeline.

Before ordering from MCI

Verify the final order summary before accepting service. Save a copy that lists the plan name, expected speed range, recurring price, promotion length, equipment, one-time charges, and contract terms. If a plan is intended for streaming, remote work, gaming, or several connected devices, compare both speed and network reliability rather than choosing on advertised download speed alone.
