Uh, isn't that unethical?
The company is owned by Carlos Slim and operates under the Tracfone umbrella. Because of Tracfone being the phone provider for all of the affiliated companies, normally the hotspot is turned off because Tracfone doesnt allow it, (many tracfones dont have data in their plans) As they created straighttalk with WalMart, they tied all the customer service operations to tracfone for cost savings and to manage training and staff.
Now Straighttalk sells wifi hotspots and the data for them, Tracfone the last time I looked did not sell the device.
With them selling devices for this type of data usage, there is no differentiation on the ability to do so.
If they didnt want to sell the data, the straight talk sim card would be set to disable it also, but its not.
The whole thing is to allow a savings by large quanity buys on phones for all of the different companies.
Technically you could possibly call it unethical, but so are a lot of things we all do daily from speeding to grabbing an extra refill from the drink machine when you leave a fast food joint.
