Hi Lordie,
With AT&T GoPhone we have a bunch of different Android devies that you can choose from as well as two monthly plans with data. GoPhone offers you the ability to use any unlocked GSM phone, any AT&T phone as well as offering LTE Data coverage for all of our customers (where avaiable), not to mention we have over 2600 Company owned reatil stores to get support from. So you may have a cheaper service, but the AT&T Advantages easily give you more.
Hope this helps!
