Another advantage that Altice offer is mobile hotspot access and international services add ons, which include international calling and roaming.

You'll also get access to the 5g network where available.

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.
