Cellular Phone Forum / Country Specific / Australian Group / April 2007Optus 2.5G
When I turned my phone on this morning, there was an SMS waiting for me. It was one I sent to myself from another phone, as a test, in December. Had been received and deleted then. Also, there was a new icon on the screen (WAP, I think). And the 2G icon had changed to 2.5G. I guess there has been a local upgrade on the NSW North Coast.. No idea how to use it, though....can't find the book. Doesn't matter.....don't need anything I haven't been using, anyway. Just thought it interesting. Motorola V3x, BTW. ----------------------------- Subvert the Dominant paradigm. Turn your TV off >When I turned my phone on this morning, there was an SMS waiting for >me.

True! I did say that! ----------------------------- Subvert the Dominant paradigm. Turn your TV off I had that happen on my v3x in Perth a few months ago, but it's still pretty patchy, keeps changing from 3G to 2.5 and 2G, so I set it to stay on 2/2.5G. I'll wait a few more months before I change it back to auto. > When I turned my phone on this morning, there was an SMS waiting for > me.

Happened again this morning. Turned the phone on at 5 AM. Was 2.5G.....looked again at 9 AM and it was 2G again. My SIM is a few years old....so I assume it is 2G. Could Optus have changed the local setup recently? And, maybe, my SIM is having problems coping? No idea. Would ring Optus.....but help lines drive me crazy. Only use them as a last resort. When on 2G, I get a Data icon. When I am on 2.5G, a Packet Data Available icon. Didn't get either until recently. -------------------------------------------------------- ----------------------------- Subvert the Dominant paradigm.

There are parts of Optus' GSM network that don't even support GPRS (ie, they're "2G")? How quaint.

Turn your TV off > There are parts of Optus' GSM network that don't even support > GPRS (ie, they're "2G")? How quaint. These days the usual explanation for cells lacking GPRS is that they're extended range cells, found in just a few rural locations. These sacrifice half the available timeslots so as to break the 35 km limit imposed by timing advance. Only half the number of concurrent calls are possible as a result. As far as I'm aware, only Ericsson make extended range cells, and they haven't found it economical to tackle the work required to get GPRS operating in this tiny, uniquely Australian specialty market.

I can't help you because I don't know what "2.5G" means. By "2G" I mean pre-UMTS GSM.

But the book for my ZTE 850 NextG phone says it (2.5G) is GPRS. ----------------------------- Subvert the Dominant paradigm. Turn your TV off > But the book for my ZTE 850 NextG phone says it (2.5G) is > GPRS. Those fractional parts (thanks Paul for a more extensive list) are very much unofficial. So disagreements about detail are possible. Your 2.5G icon may mean that you have a GPRS session going, and not just that GPRS is available from your serving cell. Unless you've got GPRS always active, something may have started a session, and in which case it may eventually close when the inactivity "linger time" expires.

I'd be checking my bill though. There may be a configuration setting somewhere in the menus to start up with a GPRS connection. Or perhaps Optus turns it on by default to tempt you to use it and spend more. This is conceivably a setting made via a control SMS you never saw.

My SE K750i on Virgin (Optus) will start up with the GPRS indicator active. After some period of time, that indicator goes away, and only returns when I initiate a GPRS session or when someone sends me an MMS. It appears to be standard behaviour for their network. > > But the book for my ZTE 850 NextG phone says it (2.5G) is GPRS. > > Those fractional parts (thanks Paul for a more extensive list) > are very much unofficial.

So UMTS rev. 8 would be the logical item to put there. If we're talking other non-GSM standards, the list above would be as long as my arm. PD SignaturePaul Day |
