When Samsung first announced plans to release the Galaxy S III smartphone, it also announced that the cloud-based data storage service Dropbox would be included in the Android 4.0 smartphone. It also said that buyers of the Galaxy S III would be able to access 48 GB of free space on their Dropbox account for two years when they bought the Galaxy S III, on top of the normal 2 GB of free space, adding up to a whopping 50 GB of free cloud storage space.
Now it looks like when the Galaxy S III is sold here in the US later this month, at least two of the smartphone's five wireless carriers won't offer all that free Dropbox space. A Dropbox support page on its official website states, "Select carriers have opted-out of the promotion on phones otherwise eligible. Unfortunately, AT&T and Verizon are among these carriers not currently participating."
The support page offers no reason why Verizon and AT&T subscribers can't get the free Dropbox support. The Samsung Galaxy S III is also being sold by Sprint, T-Mobile and US Cellular here in the US. So far, there's no indication that those carriers will join Verizon and AT&T in denying their users access to the 50 GB Dropbox offer.
