Is i3 Broadband available in Springfield, IL?
Only at the edges. i3 Broadband reports residential service to 22.6% of addresses in Springfield, IL, so most of the town is not covered and whether you can get it depends on your exact address.
Figures are i3 Broadband's own filing to the FCC for the D25 Broadband Data Collection, describing service as of 31 December 2025. Providers report where they could serve, so a percentage like this is a ceiling rather than a promise. Check your own address before you plan around it.

* This operator reports several technologies to the FCC nationally, and the federal data does not break that down by city, so we cannot tell you which one reaches a specific street in Springfield. Read the percentage as the whole company, not the brand. A national carrier files its fiber, its cable, its copper and its fixed wireless under one identifier, so a row marked Mixed can be counting a home wireless service even where the brand most people know is a fiber one. We mark a technology plainly only when at least 80% of what that operator reports nationally sits on it, or when its entire filing sits on one technology.
3 satellite providers also report covering Springfield, IL, as they do for almost every address in the country. That is not a fact about this town, so they are listed last above.
