Cannot access data or use data on Blackberry

Since 13 March 2015, I have no way of connecting to BIS. I cannot buy a bundle, I cannot access whatsapp, FB or my emails. I just bought a new Blackberry phone on the 19th of March as I thought the problem was that my phone was outdated. I have made 4 calls to Edgars who is the contact to RMCS with no luck.<br> <br> Nobody can tell me why this happened. I can just throw this phone away and buy any other phone but a Blackberry.
