Dell Offers Unlimited GPRS with New Card and T-Mobile. Dell's new card for tri-mode GPRS is $99, but it allows unlimited GPRS use on T-Mobile's network for $30 per month: The card works on Dell Latitude and Inspiron notebooks, and you can subscribe to either AT&T Wireless or T-Mobile for service. However, AT&T's plan starts at $30 per month for 10 Mb, while T-Mobile's offering is $30 per month for unlimited usage or $50 per month for unlimited GPRS and hotspot use on T-Mobile's network. Here's an important note, however: the unlimited GPRS for no additional fee does require activation and a one-year commitment, but it also only includes T-Mobile's GPRS network. How extensive that network is, I'm not sure, but the question is whether or not you're informed when you're roaming and using GPRS: can you just not connect or are you charged some enormous rate without knowing about?… [Wi-Fi Networking News]
