The Treasure Valley has been adding subdivisions faster than anyone can pave the roads, and the internet map shows it. Boise itself is still a cable town, while the newer streets in Meridian, Nampa and Caldwell were trenched with fiber from day one. Then there is the part nobody expects: Idaho has one of the strongest 5G home internet footprints anywhere, plus a bench of local wireless and fiber outfits like Fybercom, White Cloud and Safelink that outrank the national brands out east.

Our pick for most Idaho homes is Sparklight. We rank providers by how many homes they can reach, then by technology, with fiber ahead of cable, cable ahead of 5G and satellite last. Sparklight and CenturyLink reach nearly the same share of the state, but CenturyLink's reach is mostly older copper outside its Quantum Fiber pockets, so Sparklight's cable is the better product at more addresses.[1] Where CenturyLink has fiber, take the fiber.

Which internet providers cover most of Idaho?

Idaho's wiring is thinner than most states east of it. Cable at 100/20 Mbps passes about two-thirds of locations and fiber well under half. What fills the gap is radio: licensed 5G home internet reaches more than three in five locations, and unlicensed fixed wireless from local providers reaches close to half. Only two brands cover most of the state. T-Mobile, Rise Broadband, Verizon, Safelink Internet, White Cloud Networks and Fybercom cover many areas. TDS Telecom, Ziply Fiber, Newmax and Spectrum serve some areas, mostly in the Panhandle.[1]

Starlink, Hughesnet and Viasat reach almost every Idaho address. AT&T has no wireline network here; anything sold under its name is AT&T Internet Air, its fixed wireless service, and it does not register in the FCC's Idaho filings as a meaningful option.[1]

What is the best internet in Boise, Meridian, Nampa, Idaho Falls and Coeur d'Alene?

Boise is cable-first. Sparklight passes nearly every home, CenturyLink reaches nine in ten, and fiber is available at fewer than one in three addresses. T-Mobile, Rise and Verizon each cover more than half the city. Sparklight's 1 Gig offer is $40 a month for the first year for new customers with Auto Pay and paperless billing.[2]

Meridian and Nampa are fiber cities. Fiber reaches about three in five Meridian homes and two in three Nampa homes, and CenturyLink, whose Quantum Fiber build centers on the Boise area, reaches nearly nine in ten addresses in both. Nampa also has Rise Broadband and TDS, making it the most competitive city in the state. CenturyLink's fiber plan up to 500 Mbps is $50 a month with no annual contract and unlimited data.[3]

Idaho Falls is cable-first with a twist. Sparklight is at every address and fiber is thin, but Fybercom, Rise Broadband and White Cloud Networks all blanket the city, and every Idaho Falls location can get 5G home internet at 100/20 Mbps.

Coeur d'Alene and Post Falls are the Panhandle's fiber corridor. Fiber passes more than nine in ten homes in Coeur d'Alene and close to that in Post Falls. The providers are different up here: Newmax, TDS, Ziply Fiber and Spectrum rather than Sparklight and CenturyLink.[1]

Is 5G home internet a good choice in Idaho?

In Idaho, yes, and more often than we would say elsewhere. 5G home internet at 100/20 Mbps reaches more Idaho locations than cable does, and in Idaho Falls, Pocatello, Twin Falls and Rexburg the FCC map shows it at every location. T-Mobile's Rely plan is $50 a month with AutoPay, unlimited data and no annual contract.[4] Verizon's 5G Home is $35 a month with a Verizon mobile plan and no annual contract.[6] Rise Broadband, a fixed wireless provider across much of the state, lists its Family plan at $29.99 a month with an AutoPay discount, unlimited data and no contract.[5] Against DSL, take the 5G. Against Sparklight or Quantum Fiber, take the wire.

Why does eastern Idaho look so different from the Treasure Valley?

Because the national brands never built much there. In Boise the market is Sparklight versus CenturyLink with T-Mobile and Verizon as spoilers. East of the Sawtooths the top of the FCC list is local: Fybercom reaches every location in Idaho Falls, Pocatello and Rexburg, White Cloud Networks covers all of Twin Falls and Pocatello, and co-ops like Project Mutual Telephone show up in Twin Falls.[1] Those companies are not on our fact sheet, so ask them about contracts and data directly. Rexburg has the smallest share of homes without internet of any city in the state.

What should I ask before I sign up?

  • What is the price in month 13? Sparklight's $40 promo runs for 12 months.[2]
  • Is there a contract? Sparklight, CenturyLink, T-Mobile, Verizon and Rise say no. TDS and the local providers do not state it.
  • Is data unlimited? Sparklight says on most plans, CenturyLink and T-Mobile on all.
  • Is the gateway included, and what does a technician visit cost?
  • When can you be installed?
  • Do fees like CenturyLink's $1.50 monthly line item sit outside the advertised rate?[3]
