I use a vodafone sim card in my blackberry as it is the cheapest option you pay £5 a month for 30days bbm&unlimited use of internet, but when I went to do it , it says this is not availablef for your price plan. Then later I was able to talk on facebook&chat to my friends on blackberry messenger.I just presumed it was a system problem because its happened before. Than yesterday it said if you continue using the internet you will be charged £1 for 25MB . Somethings not right its always worked fine before. Do you think its something wrong with the server?maybe I should call customor services.
