    64K SIMS and ENS Phones Q&A (Resulting from Cingular and ATTWS Merger)

    http://www.howardforums.com/showthread.php?s=&threadid=492681

    Executive Summary: You don't need a 64K SIM, if you end up doing something that requires a 64K SIM, Cingular will make you get one. And Executive Washroom 3B is closed, the closest one is on 4A until 3B is repaired sometime next week.

    Okay all you non-executives who kept reading, and this applies to both Cingular and AT&T Wireless customers.

    I'm going to try and make this as comprehensive as possible, but I'm sure I'll get something wrong or leave something out, so if you KNOW you are correct, please pitch in corrections (If your getting your information from your sisters boyfriends brothers teacher who bought a cell phone last week and keeps asking why it doesn't have a dial-tone, don't bother passing along info you get from them)

    Starting on November 15th-ish Cingular and AT&T Wireless will become be presented toward the public as one company. This is called "Day 1"

    Since there will still exist two seperate networks, an Orange (formely Cingular) and a Blue (formeley AT&T Wireless) network. So that customers can get the biggest advantage of the two networks until they are merged into one, Cingular will be introducing a combination of virtual applications stored on a 64K SIM (most SIMS from before were either 32K or less) and Enhanced Network Selection (ENS) Handsets.

    Why introduce new equipment? What was wrong with the old stuff? Will my old phone still work on this new Cingular network?

    Chill man/girl, not to worry. Everyones phone will still work, in fact after Day 1 if there used to be both Cingular and ATTWS in your town, you will probably get better reception that you used to, with even more improvement in the future.

    So what does the combo of 64K SIM and ENS give me?
    As a consumer you may not notice a difference, or even care to get new equipment. About the only improvement you would see might be in battery life because your phone stops scanning for a differnet network ever 6 minutes.

    Scan for a different network every 6 minutes?
    That's right. There are these things called "MNC" that is like a "network identifier". This isn't nothing you need worry about. But right now ATTWS has an MNC of 310380, and Cingular has 3 MNC's spread out over the US (310410 and two others but I can't remember). Eventually Cingular will move all the towers/networks to 310410 but until then there needs to be a way for Cingular to "home" different subscribers on the different networks and move them back and forth, without the user having to do anything, or even being aware of what's going on.

    Now who NEEDS a 64K SIM and ENS Equipment?
    Nobody. But any new phone you buy from Cingular after Day 1 should have ENS and most new SIMS will be a 64K SIM.

    However for Cingulars purposes, the customers that Cingular will want to sell this new equipment primarily to will be former AT&T Wireless customers ESPECIALLY if they are in an area where there are only former AT&T Wireless towers and no Cingular towers.

    Why them?
    Because basically what a 64K SIM and ENS enabled Handset does is "fake" a different network for a phone to "home" on.
    Cingular needs to do this to load balance between the two networks and give them time to transition all the old MNC's to 310410

    What happens if I have JUST a 64K SIM but not an ENS enabled phone?
    Your phone will act like it did if you put a 32K SIM in it. Use whatever network is in your area, and then scan for a new network every 6 minutes.

    What happens if I have JUST an ENS enabled phone and a 32K SIM?
    Your phone will act like it did if you were using a non-ENS enabled phone. Use whatever network is in your area, and then scan for a new network every 6 minutes.

    Well if all this isn't really necessary for me, and really is the best advantage to the company, why am I getting one?
    Because if you are a former AT&T Wireless customer and want to move to one of the new rollover plans you MUST migrate to a 64K SIM and ENS combo.

    What if I have unlocked my AT&T Wireless phone, do I have to migrate to this new stuff?
    Yes. Of course you could keep your ATTWS handset, get this new Cingular ENS handset and 64K SIM and then just take the 64K SIM out and put it back into your old ATTWS handset, and you always have this backup phone handy.
    However I would not recommend that option.
    "They" say that you can get up to $150 if you return an ATTWS handset if it's high end and still in pretty good condition. Then use that credit toward getting one of these new Cingular phones.

    Oh right, one more last thing to add:

    Will current Cingular customer have to move to new equipment to gain advantage of the blue network (formerly AT&T Wireless towers)?

    No

    Will current Cingular customer have to get new equipment to change to new rate plans?

    If you are a Cingular customer and have a GSM phone that is both 850 AND 1900 MHz bands that's all it takes to move to one of the new nationwide plans coming out on November 15th.

    Next time you buy a new phone it will probably be a 64K SIM and ENS Equipment, just FYI.

    okay, another thing:

    Everyone who isn't getting all this new equipment doesn't need to do a thing. Updates will be sent out "over the air" that will update the phones to search for Cingular 310410 then the other Cingular systems, and then for "blue network" 310380.

    Then once all the networks get updated it will be setup to search for 310410 and then for other companies (like T-Mo or Cellular One or Triton PCS depending on what area you are in)

    Well i guess the v600 is only considered a basic handset, yesterday i went to a Cingular private reteailer and they checked a list of how much i would get for it if i traded it in and they said $75.00, wonder if it's the same through a Cingular corporate store....
