TracFone is the largest no-contract cellular provider in the United States. They offer cheap phones with the ability to add airtime to them based on your budget. Depending on the amount of airtime you purchase, you receive service days ranging from 90 to 365 days. To extend those service days you must purchase or add additional airtime, which can be done online or directly from your TracFone. This will ensure that your service is not interrupted and that you can continue to make and receive phone calls. Tips Writer Bio
