I just received an email from a reader who asked a very good question. She is looking into getting a smartphone and asked if she can just use the calender functions without the extra expense of the Internet data plan? I replied back with some details but suggested that having Internet access (including email) with the smartphone would be a worthwhile investment.
Some may question why they would need to access their email on their phone. But I find my day is much more efficient because I am able to access emails on the run, utilizing down time like waiting in line at the grocery store, to keep up to date on emails. Some emails come through that need to be answered right away, and I can do that with my smartphone that includes a data plan (I use the BlackBerry Curve with a voice/data plan).
The price of the data plans has become reasonable. Verizon , Sprint, AT&T and have different plan offerings. I found a great summary of smartphone data plans is available on the Yahoo Tech site from gadget hound Ben Patterson: Beginner’s Guide to Smartphone Data Plans.
For those that still don’t feel the need to access email on their smartphone, the answer is "yes" – you can use the calender without internet access. To sync the calender with your pc, many smartphones have a USB port that can be used to connect directly.
