Since last year now, I have been paying bills exceeding 2K on a blackberry enterprise plans. After heckling with the Customer service, I came to know of the following blackberry enterprise plans:
1. 899 (unlimited data plan with browsing)
2. 599 (unlimited data plan with browsing)
3. 299 (unlimited mail plan with no browsing)
surprisingly, when I had moved to the blackberry plan the Airtel folks told me there is only one plan which is 899 plan. This time when I threatened that I am going to move to other service provider, he gave me the other two options.
Interestingly, the 899 and 599 plan has no difference and yet they are 300 Rs apart. Shady company for sure. However, very good network. If they want my feedback, who is on airtel since 2001, please be more open and transparent and honest.
