Service now competes with Aio
Prepaid carrier Straight Talk has expanded its device support to include smartphones or tablets that are compatible with AT&T's LTE network. A product page noticed by Droid-Life and Engadget lists dedicated LTE-capable SIM cards for unlocked AT&T devices, which can be used for the company's $45/month unlimited plan.
AT&T recently began nationwide rollout of its own prepaid service, which is marketed under the brand Aio Wireless. The service provides several tiers, starting at a 250MB plan for $40/month and topping out with 2GB and 7GB caps for $55 and $70, respectively.
Aio's plans appear to cost more than Straight Talk's "unlimited" offerings, however the latter carrier quietly throttles data speeds. Vague language in the terms and conditions simply notes that data speeds may be reduced when usage is found to be "abnormally high" or "adversely impacts" the carrier's network, rather than placing an explicit cap on full-speed usage.
