Can you transfer the current service plan (currently$45 a month), anytime during those 30 days If I get another phone? I do Not want to transfer the Number, Just the service plan. I will get another straight talk phone from wal mart. When I did this once before when I called ST, was about 2 weeks left on the plan at that time, they told me just to Wait before I starting using the New phone. Then just get another service plan card at that time. I get my cards at wal mart. Because I just re-newed my plan, few days ago, and I am looking to get another phone in about 10-12 days.
