My experience with these two set of smart phones and their Data subscriptions as obtainable in Nigeria is as follows:
1.I have come to discover that there's more fun in using Android and other related smart phones than is obtainable with BB. I first got myself a BB because I want to know what all is about.
BB is a good device meant for various purposes; but unfortunately we are not allowed to explore its full potentials. BB conserves data than Android; but Android users enjoy more freedom than BB users. e. g some applications are not allowed or not free on BB but simply available at no cost to Android users.

2.I don't seem to understand why Internet providers seem to give more data to BB users, when in actual fact they don't really need it that much. I was on Glo Comonth and they use to give 3gbts at N1400 .00 for one month. In most cases, I discovered I do not use up to 200 Mb out of it.
This is because they placed some restrictions on it. One of Their Customer-care Agents told on enquiry that if I stream any YouTube video, visit any wap sites or use any browser like Opera, apart from the BB browser, I will be charged from my main account. And they were actually doing that when called them
And it was so. But the question is, why do you say you are giving so so amount of data for so so price and you went ahead to impose restrictions here and there? They said "the Customer is the king". How truthful is that with GSM Operators in Nigeria?

In conclusion, it's obvious that these Network Providers are simply milking Nigerians dry with their so called BB BIS subscriptions. They know quite alright that BB does not burn data as much; but went ahead to increase its volume so to attract unsuspecting masses to their baits. I dare them to extend the same to Android, Ipad and other smart phones users and let us see how generous they truly are.
On the other hand, the NCC should look into these issues critically because Nigerians are forced to pay for the services that were never rendered to them by these greed GSM networks. NCC should encourage CDMA Operators who are in better position to provide internet services at the cheapest rates. NCC should not forget that GSM facilities are not made for the sole aim of providing Internet services as it is today in Nigeria. CDMA does it better.

O yes, you should always expect better services as newer smart phones are being lunched. The beautiful ones are yet onborn.

True...the only reason why network service providers provide that much data for BB is for the fact that most of the BB users dont even use up to half of it plus the device doesnt consume as much bandwidth as other higher smartphones. It is evident from the fact that the BIS was scraped out on the new BB10 devices with a more powerful browser and higher bandwidth consumption.

Seconded
