Frequently Asked Questions
When will this plan be available?
This plan will be available for sale to Postpaid customers on 2/11/2018.
I have a POC. Can I get this plan?
If a customer with an active POC wants to migrate to the 10GB with Unlimited Basic Data plan, they have two options:
  1. Pay off their ETF to end their POC
  2. Upgrade their phone and sign a new device plan

Note: Once a customer is on this plan, purchase options for phone upgrades will only be offered as a device plan or full retail price.

Can a Paired Tablet Plan be paired to this Plan?
Paired Tablet plans are not compatible with this plan. This plan does allow the use of the phone's hotspot to tether to other data only devices.
Will the old version of the 3GB Individual Plan still be available?
The 3GB with Unlimited Basic Data plan is replacing the 3GB Individual Plan. The 3GB Individual Plan will be grandfathered on 2/11/18. Because there are still a few customers on this version of the plan with either a paired tablet, an active POC, or both, you may still see customers with the 3GB Individual Plan.
If I'm on the old 3GB Individual Plan, will I be automatically migrated to the new plan?
For most of our customers, the answer is yes. We will automatically migrate eligible customers to the new 3GB with Unlimited Basic Data plan between 2/18/18 and 3/19/18 on their bill cycles. Customers that will not be automatically migrated have:
  • A paired tablet
  • An Active POC
  • Both a paired tablet and an active POC

WiFi ON makes it easy to get CashBack.

The WiFi ON app puts WiFi on autopilot. That means you never use data when you don't need to.
