AT&T PREPAID vs Postpaid coverage
I've read such conflicting comments regarding coverage comparison between prepaid and postpaid plans.
If the coverage is really the same then why don't all postpaid customers switch to prepaid unless they just don't want to pay for the phone upfront?
Are there roaming fees with prepaid and does the prepaid plan allow you to access towers besides AT&T?
Is the data speed relatively the same?
Does AT&T give it's postpaid customers first priority and if so does this have a significant impact on the quality of prepaid service?
Are there many dropped calls with prepaid?
If you do try prepaid and find you don't have good coverage with it is it easy to switch back to postpaid?
I'm concerned because the fine print states that once you activate a prepaid phone you can only use it with prepaid plans so how would I be able to switch back to postpaid if I had to?
Because of this caveat is it better to purchase my own unlocked phone through ebay and use it?
