Frequently Asked Questions


When will I see my CashBack On My Bill credit?

When your phone usage for a full billing period is less than 2GB, you will be eligible for a $10 credit on that phone line. Your credit will be applied to the following month's bill statement. Data Usage is only evaluated for a full billing cycle. If you move to a different plan you will not receive the billing credit.

I am already a C Spire customer. Can I switch to this plan?

Absolutely! Any current customer who is on a Device Payment Plan or owns their device outright is eligible to switch to this plan. For current customers that are under a two-year promotional agreement, for a limited time you may also switch to this plan. Once you switch to this amazing plan all future phone upgrade must be purchased using our Device Payment Plan or at full retail price.

Can I use my phone's hotspot with this plan?

Yes. Speeds of both your smartphone and any tethering may be slowed after usage over 25GB during a month. Your primary data usage should be on your smartphone. Your tethering service may be canceled or otherwise restricted if you excessively roam or use the service in a way that is harmful to the network or other users.

If I have more than four lines, how much would it cost me?

That depends on the number of lines that you have. Here is a chart of all the line prices up to 10 lines.

1 $70
2 $50
3 $50
5 $70

Will my speeds ever be slowed down or will I be charged overages?

While many of our customers do not see slowed speeds, if you use more than 25GB per line in any given month, you may experience slowed data speeds. However, we do not charge overage fees on this plan. Tip: C Spire offers you the WiFi On App to gain access to over a million public WiFi networks for FREE. Check it out on iOS or Android

How is video quality with this plan?

We do not restrict or limit video quality, and you can experience the highest quality video that your data speed allows and that video content providers offer. Streaming HD quality video can result in high data usage, which could cause you to use more than 25GB of data during a month. In this case, you may experience lower data speeds, which could affect video quality.

How can I better my chances of getting the benefit of receiving CashBack on My Bill?

We believe in offering the best value to our customers. That's why we built WiFi ON. It's a free app that helps connect you to public WiFi networks without needing to log in and helps you manage your WiFi usage so you never use data when you don't need to. It manages your WiFi connection automatically.

What is the difference between this unlimited plan and your other unlimited plans I may have seen or had in the past?

We think it's better! This plan not only provides the benefit of never having to worry about overages on months you use a lot of data, it also provides the ability to get CashBack on your bill on the months you use less data. You always get great value, no matter how you use your phone. Plus, you get discounts when you add more phones to this plan.

I am on the Unlimited with CashBack on Your Bill plan. Why can't I buy a new phone with a 2-year contract?

The wireless industry has moved away from two-year contracts to lower overall rate plan pricing by removing device costs that were traditionally included in plan pricing. By moving to Device Payment Plan (DPP), you can pay less based on the device you purchase, and can upgrade early with trade-in of your device, giving you more flexibility.

Will I have to pay taxes on the free 4th line?

Taxes and fees apply to all active lines. You will still be charged for the flat-rate taxes and fees for the free 4th line. These fees may include E911, USF, Regulatory Assessment, and Administrative Recovery.

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.
