Reasonable dealing with data transmission on E71

Activate Nokia native browser and hide it in a backgroundTwo days ago I read a great post at blog analyzing how much data the use of A-GPS with Nokia E71 is consuming. Honesty speaking I was thinking about a similar post recently. Some time ago I was also afraid about the amount of data transferred when the phone is communicating with base stations to accelerate fixing my GPS position. As we all now know from the mentioned post, it is not so bad. But what if you don’t have a flat data rate, or you have only a small data package available, like 50 megabytes monthly? If you start A-GPS (for example by using application like Nokia Maps) it will consume less than 10 kilobytes and your phone will finish packet data connection. Nevertheless, you will pay for a whole data billing unit, which could be 50, 100 or even 500 kilobytes, depending on your operator rates. How to avoid it?

Use the same SPN for other internet appsThe solution is really, really simple. After waking up (YES, I turn off my phone when I sleep, weird isn’t it?) I simply start native Nokia web browser (by long pressing 0 key) and I connect to GPRS/EDGE or 3G data domain using standard GPRS access point (called APN, in my case it is ‘Era Internet’). When I finish morning browsing, I simply hide browser by pressing Home key. What happens? The connection is maintained, but almost no transmission is done, because a web page is already fully loaded. Now let’s imagine you want to check your e-mail account, or use Nokia Maps (which is using A-GPS). When the chosen application starts, it asks you to choose an APN to be used for this software. Now choose the same, which was used for the native browser. What will happen? Data session opened for the browser will be activated, but within the same billing unit. Leave the application, leaving browser still working in a background and voila! You have found a very saving way to use data transmission. My experience shows that doing it in such a way I can check my email several times during a day, plus use A-GPS, browser, or IMs and all those actions could be done without exceeding 500 kilobytes.

Define the same APN for A-GPSNow an obvious question may come to your mind. Does it have impact on battery uptime? The answer is yes, but very moderate. In comparison, this effect is much smaller than in case of push mail application using packet transmission more often. Of course if you use a flat rate it does not make sense to act this way, but for more economic usage of data transmission, Symbian S60 proves to have a really good, helpful connection manager. I’m very curious if you have any other way to save your phone bill?

    Good question about ways to save on a phone bill. Thousands of wireless customers are saving an average of $484 annually through the website by a company called Validas that provides an unprecedented level of cell bill analysis. Customers with T-Mobile, Verizon, AT&T, Sprint, and US Cellular cut their wireless bills by 22 percent on average when they use Validas.

    Here’s a quick breakdown of how it actually works. Validas analyzes your online cell bill for free and calculates how much money you could be saving. It turns out that eight of ten wireless customers are paying more than they need to for their plans. Validas fixes these discrepancies by tailoring a customer’s plan to fit their specific needs. If you choose, Validas provides your personalized cell bill adjustment report that is emailed, for five bucks, to your wireless provider in industry specific format so you can actually implement Validas’s cash saving changes. If Validas can save you more than $5 on your bill, this obviously provides a very cost effective solution.

    Validas is rapidly gaining a reputation as the preeminent advocate for the wireless customer. Check out a feature about the company on The Big Idea with CNBC’s Donny Deutsch at Any cell subscriber who wants to cut costs should consider Validas. It’s free to consult and you only stand to save.

    Happy holidays, and good luck reducing your cell bill.
