One more 64K SIM card question

artmann

Aug 10, 2005, 12:29 PM
I know this subject has been talked about many times on this forum but I did a search and wasn't able to find the answer (or maybe I just didn't see it).

The way I understand it is these new SIMs have the load balancing feature and would use both Cingular and AT&T towers and balance out the load depending on how many people are using these towers.

I am currently using the 32K SIM and I assume it only uses the Cingular towers. The reception inside my office is not so great and my question is with the 64K SIM, would I get better signal because the system will put me on an AT&T tower assuming I am closer to one?

I have a Motorola V551 and also gone through two V400 before. The phones work fine elsewhere, so I don't think the problem ...

Assuming that there is a closer ATT tower then yes, you should have a better signal with the 64k SIM.

Thanks. One more question: Would Cingular swap out my card or do I have to purchase the 64K card?

I think your phone has to have the ENS software with the 64K Sim card as well to do this. I could be wrong though.

Just because a blue tower is closer doesn't mean that getting a 64k SIM and load balancing them to blue is going to make a difference. What if the blue tower is 1900? Then it probably won't get as much building penetration as an orange 850 tower further away. Distance from a cell site does not necessarily determine quality coverage.

Theres a lot of different factors that go into load balancing. Maybe in that one location blue service is better, but in genral throughout the town the blue horrible. By switching to blue to get better service in that one spot could possibly condem you to terrible service everywhere else.

If i had the address and zip i could probably tell you if it was worth doing. Yes your phone does need to be ENS capable...

The address is 8809 Emmott Road and the zip is 77040.

I see your point. If having access to the blue towers doesn't help at my office location, then it is not worth changing. So far, my phone is working fine everywhere else.

The phone is a Motorola V551 that I just got recently.

Sorry, I thought you said you had a V400.

It looks as if the Houston market has already been integrated. There is no load balancing in integrated markets because it makes no difference. Your getting the same coverage either way.

How can you tell his market has been integrated? I'd like to know how you can tell. When I look at the MTi tool I can see the towers (blue and orange) but I can't tell if the specific market was integrated or not.

If your using the MTI tool, there's an easy way to look. It's not 100%, but it's pretty effective. If you pull up an area and then switch back and forth between blue and orange and see that the coverage is exactly the same it's usually an integrated market.

I have a friend on the technical side who has a list, so if i need to find out for sure i just ask them.

Can you find out about my area? please. Zip 32225. (NE Florida). If it's not any predictions on when it'd be integrated?

MTi tool is used by Cingular rep. We enter a phone number and a zip in it and we get a footprint. It shows towers, (blue and orange) signal strenth. etc. etc. If you are not a Cingy employee you won't have access to it. ☹️ sorry...

Thanks. So that means I have access to both blue and orange towers in Houston regardless of which SIM card I have. Correct?

Do you know in my area if they are or have converted the AT&T's 1900Mhz to 850Mhz or they are leaving them the way they are?

You seem to know what you're talking about, so here's a question for you. I'm in NYC. I have two Razr's, one a silver bought in December from Blue NBO, and one black bought three weeks ago from a Cingular retail store, phone only. (both are unlocked) I am a "Blue" customer, and I know for a fact that the silver and black have ENS software enabled. (I've verified this through looking at the SEEMs, and they are enabled by default). With the black the signal is MUCH stronger, as would be expected as the software, firmware, etc is newer and less bug-ridden. I'm curious: is there a such thing as a 64K SIM card on the blue side?, or will I have to migrate to orange to get a 64K SIM? I'm pretty knowledgeable otherwise, just this 64K thing: I've al...

Unfortanately, there is no such thing as a 64k SIM to "Blue" customers. They only work for customers who have migrated over to the "Orange" side.

I can't blame you for wanting to keep your plan though. Being a former "Blue" Loyalty Rep I know how great some of those plans were. Some people were getting obsurd amounts of minutes for 29.99, 39.99. It was crazy.

Yes indeed; another reason I don't want to switch is because the corporate discount for blue with my company is so much better than orange. Sometimes when I look at the difference between the two, I'm amazed it's actually the same company! Thanks so much for your feedback . . .
