AT&T U2800A GoPhone (black, Prepaid/Pay As You Go)

Pros: Very Basic.
Only $20.
Free with certain long-term plans.
Perfect with ATT GO (no contract) plans.
Customer service has been EXCELLENT servicing this account.
Manage your account online or by phone.
Candy-bar profile fits in small purse/pocket.

Cons: Very Basic.
Candy-bar profile allows for inadvertant key hits in purse/pocket.
That may lead to COSTLY IRREVERSIBLE charges.
Keypad Lock prevents that.
Keypad Lock is annoying.
ATT will only disable web capability if you insist.

Summary: We need a cheap, reliable, no-frills cell phone with excellent coverage/service for really limited use. Just a couple of days a month; just a couple of calls/texts a day: no gaming; no webbing; no I.M.-ing; No photos. This phone fits the bill.
The ATT GoPhone plans work for us too. And with our limited needs, neither do we miss the features it lacks, nor do we use most of the features it does.
After 2 months we are completely satisfied wth the phone and service.

You can only adjust the volume while you're on a connected call. Use the left and right navigation keys to hear the volume get louder or lower , but only while you're on the phone.
The center button is a shortcut to the Web. Money will begin to deduct from your account whenever that button is hit. Only the KEYPAD LOCK function prevents this. You cannot disable this function yourself, but if you call customer service, they can, if you insist.
