Frequently asked questions about adding a line
With our Multi-Line Savings, Optimum Mobile customers save more when they have more Unlimited/Unlimited Max lines. Get $15 off each line when you have 2–4 lines, or $20 off each when you have 5 or more. The more Unlimited/Unlimited Max lines you add, the more you save!
Once you add a new line, all eligible lines will update to the new price on your next bill. Your Unlimited Plans Multi-Line Savings will kick in automatically.
Optimum Mobile’s Unlimited Plans Multi-Line Savings apply to Unlimited and Unlimited Max Plans, but do not require the purchase of a new phone. You can bring your own phone and save!
