Those of us of a certain age (Jurassic Coders) remember when dial-up analog modem services charged by the hour for online access. And, there was a surcharge for using a faster 9600bps (not Kbps or Mbps) modem. It forced us to limit our online usage and constrained the kind of services that could be used on a budget.

Wireless data access (CDMA/CDMA 1XRT and GSM/GPRS) in the US forced those same constraints on wireless users until today. Until today, I paid $19.99/month for 10 megabytes of data access using T-Mobile’s GPRS service. Then, I read a note on PocketPCThoughts.com that said T-Mobile changed their GPRS plans today to a single plan that charges $29.99/month for unlimited data-only service or $19.99/month if you have a $29.99[or more] voice plan.

It took a couple of phone call attempts to T-Mobile’s customer service to find a representative who knew about the new plan and could help me. But, once I found that person, it was confirmed that I could switch from my old plan to the new one and that the change would take effect in two hours.

This completely changes the way I will use my Pocket PC Phone Edition to access data using GPRS. I’m already thinking of how I can benefit from increasing my on-the-go web and email access.

What kind of changes will you make in your T-Mobile GPRS data usage now?
