I have been taking a good look at the website of Grameenphone’s CellBazaar in Bangladesh. The CellBazaar initiative is certainly worth some consideration because it is one of the better established mobile marketplaces.
CellBazaar offers multiple channels for checking the listings and for submission. The mobile channels include SMS and WAP. Concurrently, all the sell offers submitted within the last 30 days are available for viewing online.
I have been particularly interested in the CellBazaar tutorials for the viewing of the available offers via mobile technology and for the submission of offers. The tutorials feature the procedures for announcing a sell lead and for checking the sell leads. The procedures (SMS Buy, SMS Sell) involve the sending of 4 text messages in order to sell, and of 5 messages in order to buy. In response, the user of the system receives lists of the available metacathegory, cathegory, sub-cathegory and price range options. The user makes a choice by texting to CellBazaar the number of the selected option.
Considering the SMS and WAP procedures one fact sticks out. In neither selling procedures (SMS or WAP) is the user required to specify his/her location. In the WAP Buy procedure once a buyer chooses the sub-cathegory of goods he/she is interested in, he/she needs to specify a location and a price range. In the SMS Buy procedure the is required to specify a price range. This all leaves the question open as to how CellBazaar is able to know the location of its users. Is anyone aware of what location technology they are using? If CellBazaar do indeed infer the location of their users without asking them to confirm it, that seems to me a rather poor practice. If it is otherwise, I would very much appreciate hearing about it.
