Virgin Mobile’s feature phone arm just added a third tier, delivering unlimited talk and texting, along with 50 megs of web access for $ 40 per month. This offering joins Sprint’s other payLo budget offerings, including an entry-level option that includes 400 minutes of talk time for $ 20 per month, and a $ 30 monthly plan that delivers 1,500 minutes, 1,500 texts and 30MB of data. Overage charges are quite hefty, at $ 0.10 per minute, $ 0.25 per message and $ 1.50 per MB (ouch!), with the option to reset the counter instead by starting a new month once you hit the threshold. Considering that the plans are designed for feature phones (which are seldom used for anything but basic web access), the tier limits do sound manageable — perhaps even a deal, if you talk a lot and never browse the web. The payLo plan can be paired with any of Virgin’s feature phones, which range in price from $ 15 (for a sold-out LG101) to $ 50 (for a QWERTY-equipped Kyocera S2300). Get the full scoop from Sprint in the PR after the break.
