ATT Now Has Day Passes -
This is lifted from DSL Reports:
As was previously noted, Verizon had started offering a trio of new prepaid wireless broadband options for those of you who couldn't find an open Wi-Fi hotspot, simply hate contracts, and don't mind paying a steep premium for bandwidth. Verizon now offers a $15, 75MB "day pass" plan, a $30, 250MB "week pass" plan, or a $50, 500MB "month pass" plan.
Not to be outdone, AT&T today has announced that they too are now going to be offering prepaid wireless broadband plans. Dubbed the AT&T DataConnect Pass, the pricing and daily usage limits mirror Verizon's plans exactly:
•DataConnect Day Pass – 75 MB – for $15
•DataConnect Week Pass – 250 MB – for $30
•DataConnect Month Pass – 500 MB – for $50
One difference in the plans is that Verizon's prepaid passes charge you overages should you cross the cap (20. 12, 10 cents per MB, respectively). AT&T's system doesn't involve overages. According to AT&T, users will get an automated alert once they reach either 30 minutes or 20 percent of allotted data usage remaining in their session, at which time you'll have to buy more time/data. Keep in mind these plans expire, so if you but the 30 day plan -- you'd best use the available bandwidth within thirty days.
To use the service, AT&T customers need a new SIM card or their existing SIM card information (SIM ICCID serial number and IMEI equimnet serial number), and then need to log into AT&T's DataConnect pass "buy a session" website.
