Optimum Mobile cell phone plans review

  • Free international roaming data

  • Good coverage

  • Great price and value

  • Good data speeds


  • Limited handset support

  • Can't easily change phone

  • Service is limited only to areas with Suddenlink and Optimum

Optimum Mobile (formerly Altice Mobile) is an MVNO (Mobile Virtual Network Operator) and operates on two major US networks, AT&T and T-Mobile.

An MVNO is a low-cost carrier that offers the same great service - by using at least one of the major telecom networks - while providing a discounted price.

As one of the newer MVNO's, having launched back in 2016, they offer some great competitive deals without being tied into a contract. However there is one small caveat, you need to be in Optimum and Suddenlink service areas to be able to sign up.

Keep reading and check out our review below to find out if this is the right carrier for you.

Optimum Mobile likes to keep it simple with a small selection of plans.

Optimum Mobile FAQs

What network is Altice using?

Is Optimum Mobile any good?

Running on the second-best network for 4G LTE in the US, Optimum Mobile provides good coverage. They also have a simple selection of plans for all needs, including unlimited data. But there's no one size fits all when it comes to phone plans. Make sure to check your usage when comparing.

How is Optimum Mobile coverage?

Does Optimum Mobile have a contract?

With Optimum Mobile there are no contracts, so you're free to leave anytime. Without any early termination fees.


Optimum Mobile keeps it simple with a small choice of plans and flexible options. But there's one small catch. To be able to sign up to Optimum Mobile you have to be in an Optimum and Suddenlink area. If not, you can still save hundreds a year by comparing low-cost carriers on all networks.

Piggybacking on both AT&T and T-Mobile gives you access to nationwide 4G LTE coverage and if your phone is compatible, 5G network (where available). All plans include unlimited talk and text, mobile hotspot use, and optional international and travel passes for international calling and roaming.

With no contract, if you're not happy you can change providers whenever you like. Still not sure if Optimum Mobile is for you? Compare our full list of MVNOs.
