Ready for 5G+? Switch to a 5G SIM card now.

ZYM is thrilled to announce the official rollout of 5G Standalone (5G+)!

To unlock these lightning-fast speeds, we are progressively inviting 5G plan subscribers (Roam Smart, Eco, Power) with older 4G SIM cards to swap to a 5G-ready card via email and SMS.

If you’ve yet received the notice, that means you are currently on a 4G plan, stay tuned—we will be extending invitations to you soon. We appreciate your patience as we work to upgrade our entire community!
