Tips to save money when switching phone carriers
Switching providers doesn’t have to be expensive. With the right approach, you can easily stay within budget. Some tips on saving when switching carriers include:
Bring your own device
One of the simplest ways to save money when switching is to bring your own device instead of purchasing a new phone. If your smartphone is unlocked and compatible, you can activate it with your new provider while avoiding paying high upfront prices or committing to a long-term financing contract.
Watch for switching deals
Many providers offer switch carrier deals to entice customers to transfer to them. These deals usually include bill credits or discounts when you sign up. Some carriers offer promotional deals that cover early termination fees or pay off your outstanding phone installment balance with your previous provider. Timing your move during these promotions can significantly lower your out-of-pocket expenses.
Use a savings calculator
Comparing your current cell phone plan against new plans helps you discover potential savings. According to NerdWallet, single plans now cost between $70 and $100 per month, while family plans range from $160 to $200, emphasizing the importance of comparing plans before switching.
Astound provides an easy-to-use mobile savings calculator that shows you what you could save by switching to Astound. Here’s how it works:
- Enter the number of lines you need
- Enter the amount of data you use on average monthly
- Enter your current service provider
- Enter your current monthly bill amount
- Click on VIEW SAVINGS to see how much you can save with Astound Mobile
If the calculator displays substantial savings, it’s an indicator that switching to Astound would be a smart financial move.
Time your switch wisely
Avoid overlapping charges for the same cell phone service by completing your move at the end of a billing cycle. In addition, timing the move to when your contract ends helps avoid early termination fees while taking advantage of seasonal promotional offers.
