Troubleshooting
- My phone suddenly says No Service — what to check, in order The ordered checklist that finds the cause fastest: outage first, then the 30-second resets, SIM/eSIM, account blocks, and software — and exactly what to tell your carrier if nothing works.
- SOS Only / Emergency Calls Only: what it actually means SOS means your phone can reach a network for 911 — just not your carrier’s. What causes it, why 911 still works, and the steps that get normal service back.
- Calls fail but data works (and the reverse): what’s actually broken Bars measure radio; calls and data are services on top of it. A symptom-by-symptom map of which layer failed — VoLTE, provisioning, data settings, or the plan — and the fix for each.
- Wi-Fi calling: when it saves you and how to turn it on The free fix for indoor dead zones: calls and texts over your internet instead of the tower. When it genuinely helps, when it can’t, the E911 address step, and how to enable it on any phone.
- I switched carriers and my signal got worse: band mismatch explained Same phone, new network, weaker signal — usually because carriers hold different low-band spectrum where you live, or your phone lacks a band the new network leans on. How to diagnose it and what actually helps.
- Is my SIM dead? How to tell in five minutes “SIM not provisioned” is a reject code from the network, not a verdict on the chip. How to tell a failed card from a dead line or a SIM swap, fast.
- Is it an outage or just my phone? Three ways to tell Full bars can sit on top of a dead network. Three one-minute tests, plus what carrier pages, crowdsourced counts and FCC outage reporting really measure.
- Phone line suspended? What it means and what to check first Check your line status, billing notices and recent SIM or number changes. Learn when to contact the carrier and why a phone reset cannot fix an account restriction.
- No service after a phone update: what actually broke A phone update moves four separately versioned layers, not one. Here is how to tell which layer lost your cell service, and why a factory reset is wrong.
Cell coverage
- Is an MVNO actually worse than the carrier it runs on? Same towers, lower price. The real difference is data priority during congestion — and the carriers’ own disclosures set that per plan, not per brand. What to read before you switch, and where it is legally required to be written down.
- How to check cell coverage by carrier before you switch Carrier maps, the FCC map, and real-world tests — how to judge coverage where you actually live and work before committing to a network or MVNO.
- Why carrier coverage maps can be wrong Coverage maps are modeled estimates, not measurements. Here’s why your real-world signal differs and how to test it.
- Indoor cell coverage problems and fixes: from free settings to signal boosters Why your phone works on the porch and dies in the kitchen — the building physics, how to diagnose your dead zones, and the fix ladder from Wi-Fi calling (free) to boosters (real money).
- Do cell signal boosters work? The rules and the physics A booster amplifies what already reaches your roof. The FCC band list, the legal gain ceilings, the registration rule, and when Wi-Fi calling wins instead.
Home internet
- How to check what internet providers are available at your address A step-by-step method that actually works: explore by area, verify at the address, and confirm the details that determine whether you can really order.
- Why internet availability differs between neighboring addresses How two homes on the same street can have completely different internet options — and what drives the difference.
- ZIP code vs. address: why ZIP isn’t enough for availability Why a ZIP code is a poor proxy for what internet you can actually get, and how to check the right way.
- Internet options for renters: what you can get and what to ask the landlord Renters can’t rewire the building — but you have more options (and more rights) than you think. What’s realistically available in a rental, the questions that save you weeks, and the no-drill setups that work.
- Is it my Wi-Fi or my internet? How to tell Your modem or ONT is the boundary: tests inside it blame Wi-Fi and your LAN, tests past it blame the line. An ordered way to prove which side broke.
- Not getting the speed you pay for? How to prove it Your plan speed is a marketing number. The FCC broadband label is the only speed your provider put in writing. How to test wired and document a real shortfall.
- CGNAT: what it breaks and how to tell you’re behind it Behind CGNAT your router never holds a public IP. What that breaks, a two-minute test to confirm it, and the exact words to use with your provider.
Fiber
- Can you get fiber internet at your address? How to find out How to verify fiber availability step by step — provider checkers, the FCC map, wiring questions for your building, and what to do if fiber stops one street away.
- How fiber gets built — and how to get your neighborhood on the map From ROI model to lit service: planning, permits, make-ready, construction, drops, and activation — why fiber takes months to years, and the levers residents actually have.
- Fiber vs. cable internet: the real differences (and when cable is fine) Upload symmetry, latency, congestion behavior, reliability — where fiber genuinely wins, where modern cable keeps up, and how to decide with the options you actually have.
- Fiber is across the street — but not at my house. Why, and what to do The most maddening availability gap explained: build boundaries, drop economics, aerial vs. buried plant, and MDU wiring — plus the concrete steps that sometimes get your side of the street built.
5G home internet
- 5G home internet vs. cable vs. fiber: which should you actually get? A use-case-first comparison: consistency, upload, latency, caps, install friction, and portability — and a decision framework that starts from what’s at your address.
- Will 5G home internet be fast enough for you? The capacity caveats, explained Why the same 5G home internet product delights one address and frustrates the next: sector capacity, deprioritization, signal quality — and a two-week trial protocol that gives you a real answer.
Rural internet
- Rural internet options: a realistic decision ladder (not a hype list) Fiber co-ops, WISPs, 5G home internet, LEO and GEO satellite, legacy DSL — what each is actually like in rural America, and the order in which to try them.
- Satellite internet: LEO vs. GEO, and who should choose it Why orbit height decides everything — latency, dishes, weather behavior, capacity — and an honest read on when satellite is the right call versus the fallback.
- Fixed wireless internet explained: WISPs, 5G home, and the line-of-sight reality Two very different products share the “fixed wireless” label. How each works, what actually determines your speed (spoiler: trees), and the questions that separate a great WISP from a bad bet.
Data accuracy
- How accurate is the FCC National Broadband Map? The FCC map is a twice-yearly snapshot, not a live database. How old today’s data really is, the two ways it gets an address wrong, and what a challenge does.
- Why “available” doesn’t always mean you can order it today Why a provider can show as “available” at your address and still not be orderable — drops, wiring, capacity, and waitlists explained.
Remote work
- What internet speed do you need to work from home? A practical guide to the download, upload, and latency you actually need for remote work — and why upload and latency matter more than headline speed.
- Latency, jitter and packet loss: what Mbps hides Your speed test looks fine and your calls still break. What latency, jitter and packet loss each do, which thresholds are real, and how to measure them.
