The sign-up page shows $50 a month. A promotional deal shows $25. Both are real — they just represent different lock lengths and different conditions. The price lock on the 1 Gig plan is also shorter than the rest of Optimum’s lineup, and the fiber version behaves differently from the cable version at this speed in ways that matter day to day. This guide covers all of it, plainly, so you know exactly what you’re agreeing to before the first bill arrives.
What the 1 Gig Plan Actually Costs — and What Most People Miss
Optimum’s 1 Gig plan has more fine print than any other tier in its lineup. These are the nine questions worth answering before you sign up.
Two rates exist simultaneously. The standard rate is $50/mo with AutoPay from a checking account and paperless billing, locked for 60 months per Optimum’s published broadband facts label for the 1 Gig Fiber plan. A limited promotional rate of $25/mo exists at some addresses for 36 months. Without AutoPay from a checking account — if you pay with a credit card or manually — every version costs $10/mo more. Taxes and government fees are additional at every price level. The gateway is free for the first 12 months at most addresses.
This is the detail that trips up most people comparing Optimum tiers. While the 300 Mbps and 500 Mbps plans carry Optimum’s 5-year price lock on standalone internet, the standard 1 Gig plan comes with a 3-year (36-month) lock. That’s still better than the 12-month promotional windows other cable providers use, but it’s two years shorter than what you get on the lower tiers. The way to get a 5-year lock on the 1 Gig plan: add an Optimum Mobile line within 30 days of activating internet. Optimum’s own upgrade page confirms that the 60-month price lock on 1 Gig requires adding mobile service.
After 36 months, Optimum’s terms allow the price to rise by no more than $15/mo per year until it reaches the prevailing standard rate. The prevailing rate can be meaningfully higher than your starting price — Optimum’s broadband facts labels describe the potential gap as reaching up to $80 or more above the promotional price, depending on the tier and market. The practical move: set a calendar reminder for month 33 of your service, call retention two to three months before month 36, and negotiate a renewal rate before the first increase applies. Waiting until after the bill climbs weakens your leverage.
Both are priced identically and carry the same download speed. The fiber version delivers approximately 940 Mbps upload to match its download — symmetrical speeds in both directions. The cable version delivers around 35 Mbps upload. That’s not a typo: a cable gigabit plan gives you roughly 1,000 Mbps coming in and 35 Mbps going out. This is structural to how cable infrastructure works and applies to every cable gigabit provider, not just Optimum. If Optimum’s fiber reaches your address, the fiber 1 Gig plan is the clear choice at the same price. The plan name tells you which you’re looking at: “1 Gig Fiber Internet” is fiber; “Optimum 1 Gig” is cable.
For the overwhelming majority of households, 500 Mbps is enough — and saves $10/mo with a longer 5-year lock. The FCC’s current benchmark for a household with several active devices is 100 Mbps. At 500 Mbps, a family of five can stream 4K simultaneously, hold multiple video calls, and game without the connection being the limiting factor. Where 1 Gig makes a tangible difference: very large households with many simultaneous users, people who transfer enormous files regularly, or households where multiple people work from home with heavy bandwidth needs at the same moment. The more honest question is which version of 1 Gig you’re getting — if fiber is available, 1 Gig fiber is a meaningful upgrade over 500 Mbps cable because of upload, not download.
Yes. Adding an Optimum Mobile Unlimited line credits $20/mo off your internet bill, dropping 1 Gig from $50 to $30/mo — and extends the price lock from 3 years to 5 years simultaneously. Adding both mobile and Optimum’s Entertainment TV on top of that saves up to $30/mo total on internet. The bundle credit requires mobile sign-up within 30 days of internet activation; if you miss that window, the credit doesn’t apply retroactively. Both services must stay active for the credits to continue — canceling one drops the credit tied to it.
The most important one is the gateway equipment fee that starts after month 12. The gateway is free for the first year, then can increase by up to $5 per month per year until it reaches the standard equipment rate. For existing customers upgrading to 1 Gig, Optimum’s upgrade page shows the gateway already at $14/mo from day one — free gateway is a new-customer benefit. Optional Whole Home WiFi extenders add $5/mo. Self-installing with the MyOptimum app avoids the up-to-$100 professional installation fee. There are no data overage fees and no early termination fee.
Currently yes, on qualifying sign-ups. A $50 Visa Prepaid Card is available when you sign up for a standalone 1 Gig plan or higher. That increases to a $100 Gift Card when you bundle with either Unlimited Mobile or Entertainment TV, and to a $200 Gift Card when you bundle all three. Cards are issued approximately 90 days after activation and expire within 6 to 12 months of issuance. You must register any rebate within 30 days of activation, maintain your account in good standing, and have no past-due payments during the qualification period. Specific terms vary, and promotional offers change month to month.
Optimum’s broadband facts label describes speeds as “up to” the advertised figure over a wired connection. WiFi speeds vary and are not guaranteed. Real-world data from independent speed testers puts the average measured download on Optimum’s 1 Gig cable plan at roughly 780 Mbps — about 78% of the advertised speed — during typical usage hours. If you’re consistently seeing speeds dramatically below that, run a wired speed test at fast.com or speedtest.net during off-peak hours and then again at 8–9 p.m. on a weekday. A large drop during peak hours suggests node congestion rather than a problem with your individual line. Call technical support with both numbers documented; congestion at your node is a legitimate reason to request a service credit.
The Full Monthly Cost of Optimum 1 Gig — Every Scenario
The $50 advertised price is the floor for most customers. Here’s what each version of the bill looks like across real situations.
If you’re already an Optimum customer and you call to upgrade your existing plan to 1 Gig, the free gateway period does not apply — Optimum’s upgrade page shows the gateway billed at $14/mo from the first month for upgrading customers. The 3-year price lock applies to the upgrade, but the free-equipment benefit only comes with new service activations. Factor that $14/mo into your cost comparison before deciding whether upgrading makes sense versus signing up as a new customer at a different address or through a different promotion.

1 Gig Cable vs 1 Gig Fiber — The Difference That Actually Matters
Both cost $50/mo. Both advertise 1 Gig download. One delivers 35 Mbps upload. The other delivers 940 Mbps upload. That gap defines which households each version actually serves well.
A cable gigabit plan delivers roughly 1,000 Mbps coming in and about 35 Mbps going out. A fiber gigabit plan delivers approximately 940 Mbps in both directions. The gap is structural — cable infrastructure allocates the vast majority of its available spectrum to downstream traffic, and this doesn’t change regardless of which cable ISP you use or which plan you buy. Independent speed analysis confirms that a 1 Gbps fiber plan delivers roughly 26 times more upload bandwidth than a 1 Gbps cable plan at the same tier.
For most households that primarily receive content — streaming, browsing, gaming as a single player — 35 Mbps upload is workable. But two people on simultaneous video calls, cloud backups running in the background, someone sharing a screen during a work meeting, and a smart home uploading camera footage can collectively push a cable connection to its upload ceiling even at 1 Gig download speeds. If fiber is available at your address, choose it. The price is identical.
Cable is a shared medium at the neighborhood level — when many customers on the same node are online simultaneously, which happens most nights between 7 and 10 p.m., available bandwidth per household drops. Independent speed testing finds that cable internet delivers 70–85% of its advertised speed during these peak hours, and that congestion effect compounds when the node is serving many gigabit customers. Fiber runs dedicated strands from the provider’s equipment to your home — there is no shared neighborhood node. A fiber customer’s speed during the 9 p.m. prime-time hour looks almost identical to a 3 a.m. speed test. If your measured download speed tests at 780 Mbps in the morning and 580 Mbps at 9 p.m., that’s a cable node congestion pattern, not a problem with your individual connection.
When Optimum displays plans for your address, the fiber version is labeled “1 Gig Fiber Internet.” The cable version is labeled “Optimum 1 Gig.” If both appear, choose fiber — they cost the same. If only “Optimum 1 Gig” appears, fiber hasn’t reached your block. Cable 1 Gig is still a solid connection for most households, but factor in the 35 Mbps upload ceiling and the peak-hour consistency pattern before deciding whether 1 Gig cable justifies the $10/mo premium over 500 Mbps cable for your household’s actual usage.
Find Your Situation
On cable, the answer for most households is no. You gain roughly 370 Mbps of additional download headroom that the majority of household activities never touch, and your upload goes from 20 Mbps to 35 Mbps — a real improvement, but still a ceiling. You also lose two years of price lock protection, since the 1 Gig plan locks for 3 years versus 5 years on the 500 Mbps plan.
On fiber, the calculation changes entirely. Upgrading from 500 Mbps fiber to 1 Gig fiber for $10/mo more doubles your upload speed from 500 Mbps to 940 Mbps — and that matters for households where multiple people work remotely, upload large files, or run a home server. If fiber is what’s available and $10/mo is manageable, 1 Gig fiber is a meaningful upgrade. If you’re looking at cable options only, the 500 Mbps plan with its 5-year lock is usually the stronger long-term value.
Pull up your original sign-up paperwork or the Broadband Facts label from activation. The three most common causes: the AutoPay discount stopped because a debit card expired or your payment method changed to a credit card; a bundle credit tied to a mobile or TV line disappeared because one of those services was canceled; or the 3-year price lock expired and the first annual step-up applied. Check your bill line by line against your original terms. Call 877-794-2724 and ask the agent to walk through every change on your account since activation. If the internet service price itself changed before month 37 and you have a price lock, that’s an error — request a correction in writing.
Call Optimum’s retention line 30 to 45 days before month 36. Use the phrase “customer retention” when you call — these agents have tools that general customer service agents don’t, including promotional rate renewals and loyalty credits. Before you call, look up the current sign-up rate for Spectrum, Verizon Fios, or any other provider at your address. Have the plan name, speed, and monthly price ready. Tell the retention agent what you found and ask what they can do to keep your business at a comparable rate. Asking to add a Mobile line at this point — if you don’t already have one — also unlocks the 5-year lock and a $20/mo internet credit simultaneously, which can make the math work out better than any other single move.
Add an Optimum Mobile Unlimited line within 30 days of activating your internet service. This does two things at once: it extends your price lock from 36 months to 60 months, and it credits $20/mo off your internet bill, dropping 1 Gig from $50 to $30/mo for the duration. Optimum Mobile’s Unlimited plan starts at $30/mo per line standalone. If you’re already paying for a mobile line elsewhere, the $20/mo internet credit can offset the mobile cost entirely, making the switch cost-neutral or better. Make sure both services stay active — if you cancel the mobile line at any point, the internet credit drops and the 5-year lock reverts to standard terms.
Two things change from what a new customer experiences. The gateway is billed at $14/mo from day one — there’s no free-equipment first year for upgrades. And the standard upgrade comes with a 36-month price lock on the 1 Gig tier; adding Mobile upgrades that to 60 months. Optimum’s upgrade page confirms a typical cost increase of $15/mo from your current bill when moving to 1 Gig or higher — meaning if you’re on the 500 Mbps plan at $40/mo, expect around $55/mo after the upgrade plus the $14/mo gateway. Call to confirm exact pricing at your address before agreeing, and ask whether any current promotional upgrade offers are available that might reduce those numbers.
Sign up as a new customer to access the free-gateway first year, the prepaid card offers, and any current promotional pricing. If your current provider charges an early termination fee, Optimum offers a contract buyout of up to $500 to cover it — confirm this at sign-up and keep documentation of your ETF for submission. Choose self-setup through the MyOptimum app to avoid the up-to-$100 installation fee. Register any prepaid card or gift card promotion within 30 days of activation — the window closes and there are no extensions. Keep your current provider active until the Optimum installation is confirmed working; switching before testing leaves you with no fallback if there’s a day-one issue.

An in-store visit sometimes produces pricing that doesn’t appear online. More importantly, you can verify which infrastructure — cable or fiber — actually serves your address before signing up.

Optimum Phone Numbers Worth Saving
Retention agents and new-service agents have access to different offers. Use the right line for what you need.
When you call to order or are checking out online, ask specifically: “Is the 1 Gig plan at my address cable or fiber?” The answer changes the value of the plan considerably. If the agent can’t tell you clearly, enter your address at optimum.com and look at the plan name — “Fiber” in the name means fiber; no “Fiber” in the name means cable. That single detail is worth confirming before you commit, because both plans cost the same and the upload difference between them is substantial.
