Most cell phone companies require a deposit if you have poor credit or have missed payments on your prior cell phone bill. According to Sprint, the decision to request a deposit, length of deposit and amount of deposit is determined by your credit history, payment history and other factors. If you have good credit and are in good standing with prior cell phone payments, then you'll generally not have to worry about a deposit, but if your credit is poor or you've missed a payment, you may need to pay some money up front.
Visit the Annual Credit Report website to get a free credit report from all three major credit bureaus, including TransUnion, Experian and Equifax (see Resource). The annual credit report website is the only authorized free credit report website. Look at your credit scores from all three bureaus; if your average score is 600 or below, Sprint will most likely require a deposit from you. A credit score of 600 or less represents poor credit.
Look over your records to see if you've had any missed cell phone payments or canceled payments in the past five years. Canceled plans or late payments raise a red flag and will almost always ensure a deposit with Sprint; but anything past five years is generally forgiven.
Call Sprint or visit your local Sprint store. The only people who can tell you for absolute certain if you need a Sprint deposit is someone from Sprint. Upon your inquiry, he will run a credit check and check for any missed payments or canceled plans.
