When I bought Blackberry my major change was pushing  my number from Prepaid to post paid so that I can avail the service BlackBerry provides which is not available for prepaid users. In this process my expenses on phone was pushed from 300 per month to 600 per month and if I a travel I pay extra for roaming too and all that so I can check my mails and get some messenger services. It is definitely an extra cost but since it helps me a lot I live with it.

However good news for people like me that BSNL is offering BlackBerry services even on prepaid number which is a great news as few of handsets of Blackberry like 8520 is network free and number portability is also starting this april, so if you current service provider doesn’t give you BlackBerry services on prepaid you still can get it by switching it.

Here is the plan and price plan of Blackberry Services with BSNL :

BlackBerry ® Unlimited tariff plans

1. Charges for other Tariff Items as per selected plan
2. Existing 2G postpaid and prepaid Blackberry service user under both BIS and BES can avail 3G facility with an additional FMC of Rs.50 under postpaid and STV of Rs.21 (Incl. Service Tax) for getting 3G facilities.
3. Service Tax as applicable will be charged extra.

The plan is very useful that you get BIS on prepaid and you have 3 options. Like on my plan I dont have anything except Mail / Messenger services. I often look for Social Networking features too but with BSNL you can opt for Social Networking Plan at the same price. Read more about Blackberry Traffic on Prepaid mobile via BSNL
