My family has a family plan with US cellular that includes unlimited messaging, i believe unlimited minutes, and 3g internet access. My family all have the Motorola Electrify(3g) phone. the first 4g phone came out recently. does anyone know if i could use the 4g internet access on our current plan if i get the new 4g phone without needing to get a new plan or extra fee. on uscc.com they said it wouldnt cost extra but would there be a need for a new plan?
