I have Iowa Wireless as the GSM carrier here for service, and I was wondering if it would be worth my time to call them and ask them to report on my credit report for my timely payments. I personally feel that if the wireless carrier is going to look into your credit, they should report your timely payments. Even if I don't have the cash to cover the bill, it gets automatically billed to my Visa Card, which means the payments are always on time, and that makes another positive tradeline. I have a monthly plan that is under contract.
