I am having a lot of problems with my current service plan in Baltimore- it cuts off calls, doesn't allow me to call out and doesn't send texts. Everything happens randomly and I don't know why this happens. I purchased a new phone and it is still happening. I am using a company called Visible (which works on Verizon lines). Someone suggested I switch to T-Mobile. Just wanted to know what works in Baltimore and what other people use before I transfer my number.
