Does anyone know if I sign up for SERO with the $30 plan, would they allow me to upgrade to the $50 plan if I want to increase my talk minutes down the line?
Yes they would. You just need to call in, and request to be put on the 1250 SERO plan. And you will pay the 49.99 per month, for the 1250 minutes, unlimited text, and unlimited data. So...
