But surprisingly, most of the customers are dumping their BlackBerry devices.
An internal memo sent within T-Mobile indicates that 94% of customers participating in the BlackBerry trade-in program have switched to other types of devices, according to a report by TmoNews.
Those results are notable considering what led to T-Mobile launching the trade-in campaign in the first place.
Last month, loyal BlackBerry customers as well as BlackBerry CEO John Chen blasted T-Mobile through social media and on the Web after the Seattle carrier began messaging BlackBerry customers with an offer to switch to the Apple iPhone 5s for $0 down.
The complaints caused T-Mobile to launch the current campaign, which offers $200 credit when customers trade-in their old BlackBerry and upgrade to a new device. Customers who choose a BlackBerry Q10 or Z10 get an extra $50 discount.
Despite the loud complaints, it seems there were many BlackBerry customers who were ready to leave the struggling platform, according to the TmoNews report. T-Mobile has yet to confirm the accuracy of the memo in the report, but TmoNews has a track record full of accurate reports regarding T-Mobile news
Neither T-Mobile nor BlackBerry could be reached for comment.
