Optimum Mobile plans

Optimum Mobile uses T-Mobile’s mobile network, so you’ll get standard features like 5G support and nationwide cellular coverage. For prospective customers, Optimum Mobile offers several per gigabyte and unlimited data plans.

Optimum’s 1 GB plan ($15/mo.) is in line with the competition, as Xfinity Mobile and Spectrum Mobile’s 1 GB plans cost $15 and $14 per month. But Optimum Mobile’s 3 GB plan is cheaper per month compared to both competitors.

Data effective as of publish date. Offers and availability may vary by location and are subject to change.
1 GB, 3 GB & Unlimited & Unlimited Max plan details: AutoPay required. New Optimum Mobile lines only, cannot be applied to existing lines of service. Pricing, offer and terms subject to change at any time.

With Optimum’s Unlimited plans, you’ll get features like large data caps and multi-line savings. Your monthly rate will go down by $5 for each line you add to the account (for up to five lines). Unlimited Max’s 50 GB cap is impressive, as we rarely see providers like Optimum Mobile have caps that exceed 20 GB.

By comparison, a 50 GB plan (with a five-line account) would cost the same with AT&T compared to Optimum Mobile—$35 per line. But AT&T’s 50 GB plan comes with bells and whistles like 15 GB of hotspot data per month and AT&T ActiveArmor mobile security. With Optimum Mobile, your benefits start and end with cellular service.

Optimum Mobile’s overage policy is similarly stingy. Once you exceed your plan’s cap, your internet speeds will be lowered to 128 Kbps or 512 Kbps (depending on your exact plan). At these speeds, your phone’s internet connection will be borderline unusable. With competitors like Xfinity Mobile, your plan’s overage speeds will be around 1 Mbps, so you can still use your phone for basic web browsing.

What to look for

Optimum Mobile has its share of unique features compared to other cellular providers. Before you sign the dotted line, here’s what you’ll need to know about Optimum Mobile.

CDMA vs. GSM phones

Cellular networks are built on two competing systems: CDMA (Verizon) and GSM (T-Mobile and AT&T) networks. Because Optimum Mobile uses T-Mobile’s network, your phone may not work if you were previously with a provider like Verizon or Xfinity Mobile.

Is Optimum Mobile worth it?

With downsides like large activation fees and aggressive overage throttling, Optimum Mobile doesn’t necessarily separate itself from the pack. But Optimum Mobile’s decent monthly rates and wide availability make the provider a decent option if you’re interested in an Optimum service bundle.
