An update, I tried calling both sims last night, On the new "test" sim, I was able to recieve the call this time. I am not cofedent it will continue to work. Now the VERY STRANGE part
When calling the original sim that has had the issues, I no longer get the Virgin recording "hello there, it looks like you do not have enough credit to place this call"
What I get now is "hell" (the o is cut off) then a pause, then I get about 30 seconds of what seems to be a recording in Spanish. (My best guess is Spanish) I dialed 3 times in a 2 hour period and the same thing happened. What is going on
