Unlimited SIM card benefits
MVNOs - or Mobile Virtual Network Operator - are the best route to go down for cheap cell phone plans. By hopping onto one of the major networks prepaid SIMs offer the same great service you trust but at half the cost. You get greater flexibility, can keep your phone and number and no long contracts to keep you tied down.
Same great nationwide coverage: These cell phone carriers operate on the very same networks as the big three carriers.
Much lower prices: Save up to $600 per year on your cell phone plan. Why are MVNOs so much cheaper? They don't have the huge overhead and advertising costs the big guys do.
No contracts: Don't get trapped into a two-year agreement. Switch carriers when you decide to with a no contract phone plan.
Same cell phone service: Just because you're paying less, that doesn't mean you have to scrimp on features. Plans with unlimited everything are easy to find from these prepaid carriers. Usually, a low-cost carrier plan comes with unlimited talk and text as standard, high-speed data, and even mobile hotspot data features.
Keep your phone and number: You can bring your own phone and keep your phone number. No need to sign up for pricey device payments.
Customize your plan: You decide how much data you need. Choose to pay as you go, opt for unlimited or no data, minimal minutes, or unlimited talk text and data. Unlimited data plans come at a much better price with an alternative carrier. Pick the plan options that fit your budget - not the one your carrier thinks you need.
