Cincinnati Bell G1 - 3G and old Red SIM cards - G1 General

I still have my old red SIM card from Cincy Bell and I've held on to it like it is a piece of gold since I read when I first got my G1 that the old SIMSs were the only SIMs that would allow 3G connection. Does this still hold true? I wanted to get my daughter a G1 and was concerned she wouldn't get 3G due to this. Thanks for replies in advance

I have Cincinnati Bell and when I got the phone around a year ago Cincinnati Bell's 3g would NOT work with the new SIM cards. I also recently talked to a CB employee who said they were calling people who had Blackberry's and the new 3g SIM and getting them back.
So as far as I know if you want 3g you need an old SIM card. If you go to the CBW store they should still have the old ones and will switch over your daugher's for free...assuming the still have them, which I'm pretty sure they do.

SIM question relating to phone strength

My boss bought a Treo 650 and I showed him how to put the SIM in. I noticed his signal strength had 5 bars. He wanted to see if it was unlocked so I put in my Tmobile SIM. When I turned it on, he had 2 bars. I kept it on and moved it around a bit and it moved between 1 and 2 bars. Confused, I put his Cingular SIM back in and up popped 5 bars...sometimes 4, but mostly 5.
Now, does it make any sense that my Tmobile SIM would cause his phone to have less strength than his Cingular SIM?? Or was this just some type of flook?? His Treo is Cingular branded...if that matters, but his SIM is left over from AT&T days.
His phone is a branded, unlocked Cingular. Mine is an unlocked i-Mate K-Jam.
Anyone with any thoughts?
Tom
Well if your in America. Sad to say the T-Mobile is smallest in coverage in area, and members. So the area you in might not have as much as Cingular. In america, Cingular, Verizon, and Sprint has the best coverage.
BTW, want to now how to get a promotion, introduce him to Windows Pocket PC's.
First, giving him a WM5 product is not going to get me a promo. He'll have such a tough time using it he'll get mad at me for recommending it. Believe me....I've thought about that as I have a K-Jam and love the heck out of it. Some people need the simple things.
Regarding Tmobile, I switched from Verizon to Tmo about 6 years ago when I started traveling to Europe several times a year. Initially the service sucked, but over the past 2 or 3 years I've had 0 problems with it. I travel around the country and internationally and I have to say that I'm pretty happy with it. I'm sure it's a "your mileage may vary" situation. Matter of fact, I don't know anyone who complains about their service regardless of who it is.
That being said, even if Tmo sucked majorly, that wouldn't explain why my SIM would cause him to get weaker reception than his AT&T SIM. Keep in mind, I'm using the same Treo with 2 different SIMs and get 2 different readings.
Thanks,
Tom
I have heard from some post over at Howard Forums that the Cingular 64k SIM's get better reception than the AT&T 32k SIM's.
I migrated over from an AT&T SIM to a Cingular one and noticed that my reception improved a signifigant amount. So there may be something to do with how the SIM's are designed.
Well, I'm going to run down to the Tmobile store today and see if I can't pickup another SIM. I'm pretty interested in seeing what happens.

of course it did
Your phone went from sticking to AT&T towers to Cingular towers.
OP: I doubt a new SIM from TMobile will help you. Chances are TMobile coverage in your area, as most, isn't good.
SIMs and Signal Strength
The reason a sim can dictate the signal strength is the sim has a certain amount of programming on it that tells the phone and its receiver about the services on the network. Have you ever seen a text message with "OTA OK" ? That's an Over The Air update to the sim updating things such as service pointers and things to make it easier for the phone to use the services on the network and find towers easier and quicker. You can have a sim go bad and not be able to take an update causing alot of problems or very little but noticeable problems like not receiving SMS or sending MMS. It's a modular network built on a lot of small pieces and all of them have to work together to make the services work correctly.
Sorry for the diatribe.....
I'll go back to my corner now.....

Cingular 8525 3G service with a ATT sim card

I’m thinking about buying a cingular 8525 phone, but I am currently under the old ATT network and have the a ATT sim card. I have not switched my service to cingular. If the phone is unlocked will the 3G service work with the old ATT sim card? I spoke with a cingular/ATT customer service agent today and they said I need to have the new upgrade cingular 3G sim card for this service. Does anyone have an old ATT sim that works with the 3G service? Thanks
YOU NEED to migrate over to cingular at&t doesen't work on 3g it works on 1900 mhz thats why your service sucks in doors . cingular will make you sign on a 2 year contract and you WILL NOT be able to keep your same plan, but the service is so much better on Cingular

I can't address whether or not a blue sim will work on 3G, but it stands to reason that it won't. However, if you're saying that AWS only works on 1900 MHz, I have to disagree. I have used blue sims in several phones, including an 8125 that was unlocked, and know by the buzzing interference they cause, confirmed by the test mode on a couple of Nokias and the 8125, that they worked on 850 MHz when it was available.
Be that as it may, I just got an orange-sim'ed 8525 a few days ago and am very impressed with the increased receive sensitivity and audio quality. I'm looking forward to trying it in a 2G area, but I'll have to travel a bit to do that - I live in a GSM-only service area.
(What color are the NEW sims going to be? Light blue? )

To directly answer your question, I have a TyTn with a old AT&T wireless SIM and it works fine with 3G on Cingular. So the answer is you don't need a new SIM for it to work. But you might run into the same problem I did. I previously had an 8525, bought just before xmas. I tried to unlock it with the free program offered here and was unsuccessful. It seemed like it was radio locked like the new Softbank X01HTs and I don't think there's a solution for that yet, or coming anytime soon. I ended up just returning the 8525 and buying an unlocked TyTn. It might have just been my bad luck with that one particular 8525, or it might be that Cingular is now selling all of them radio locked like the X01HT to prevent them from being SIM unlocked. I have no idea which case is true. Just a warning of what you might be in for if you don't buy an already unlocked 8525 or a TyTn.
As I understood Cingular is now AT&T again starting Monday. Should help with compatibility, right ?
I spoke to another Cingular/ATT agent last night about 3G service with the ATT sim. They said that it might work, but would work better with a Cingular sim. It depended if the old ATT towers had the 3G service installed on them. It sounded to me like they were guessing. I have a great ATT plan so I do not want to switch over to Cingular. Currently I have a I-mate K-jam with an ATT sim card and it works great with the Edge. On the subject of the TyTn I looked in to buying one, but if it breaks I have to ship it to Wales for warranty work according to HTC. I live in the U.S. So I was thinking about a JasJam or 8525. Thanks for your help
My Tytn works on 3G with the old school AT&T sim. I can't really speak on the reliability because i was only in a 3G area for a brief enough moment to test it.

Just call Cingular and ask them for the unlock code. They had no issues giving me the unlock code. Unlocked just fine.

I tried that twice, maybe I was just unlucky again but they wouldn't give me the code either time. Doesn't matter now that I have a TyTn though.
My boss just go the unlock code from cingular by saying that he travels to other countries a lot. They made him wait like 2 days and they emailed it to him.
Ok, One person says it does not work, one says it does. Does anyone else have any experience with this? Just would like to know for sure before I go out and buy it.
Thanks
It does work for me just fine with white ATTW sim card. No problems whatsoever.

I am using unlimited Mmode plan ($24.99) with a Blue ATT SIM older than the white SIM and it works with no problems.
The new sim has more storage space on it.
That is all I know.
I'd really like to figure out what else is different as well.
Same here. Getting UTMS/3G connection (comfirmed with 128k stream from radioio) with blue AT&T sim on a 24.99 unlimited mmode plan. HTC branded TyTN from egadgetdepot. What's more, my EDGE throughput is noticably higher than on my Treo 650.
Thanks for your help.
Some of you still have the 24.99 internet plan for smart phone. I think I pay something like 45.99 a month for my K-Jam. I had the 24.99 plan but they made me change it because I told them I had a K-Jam. I needed help configuring my K-Jam. The tech person told me I had the wrong plan and I would be charge a lot of money for have the wrong plan. Thats how they found out and I was unsure at the time so I just when with it.
Again, thanks for your help.
I heard there was an Audit department which would find out..
I argued about the plan change myself for over an hour with them.
I had a PDA phone before and I did not have to switch..
I still got full internet and they didn't know JACK!
Anyway.. I got a credit of 20 bucks a month for 1 year..
So I am paying the same for unlimited except now I need to pay for Text Messages..
After the year is up I'll probably change the service again to something else..
They also were try sell a plan for my notebook computer for 70 bucks a month. Since then I have used my pda a modem and had no extra charges

New Sim card

So after having problems with the new Radio i called up t mobile to just give them BS and they were like maybe it is your 7 year old SIM card causing you the problems. I didn't think it mattered that much at all. So they told me to go get a new SIM card in the store. Free of charge. After getting the new SIM card, i have full 3G all the time no matter where i am at in the twin cities in MN. Not sure why the new SIM card fixed it but it did.
Thats cool. I had the same problem with my g1 the sim just died 2 nights ago. I went into the store they told me $20. But I had 2 old sim cards at home. I called them up actived it and it was free
Wow, that is one old sim card...I didn't even know tmobile has been in the usa that long. Mine is 3 years old and has not had any 3G issues.
well i have been with t-mobile since they were called voicestream. which if i remember right means i have been with them for over 7 years now.

In general, the SIM card does very little, but it does have some info on it, and so forth. ie, AT&T 3G only works if you have an AT&T 3G sim card... I do not know the technical reasons behind it, but old sim cards can cause issues, especially with 3G.
I too have been with them for 7 years now, and I get 3G. But now I am wondering if I'm not getting it in certain areas, or getting less than perfect connection because of my old sim card?

I have been, too. And it's really annoying that it says "Vstream" in the carrier field on the lock screen...
Does yours do that?
My last two phones (SE P900 and SE P1i) both were smart enough to pull the actual carrier information and displayed T-Mobile (or whoever I was roaming on)... how can this phone not see that?
I've been pulling my hair out trying to figure out what file in the ROM translates the carrier info to the text.. where the hell does it pull that from?
I'm assuming if I go over to Tmobile I can get a new SIM that will have the proper carrier info, but... hell... I'm lazy and I'm not having any 3G issues... and I dont' want them to charge me.
Any ideas? So far you're the only other person I've seen that's also been a Vstream member.
Oh and.. yes... I started with Voice Stream by importing the very first color phone (AFAIK).. the SE T68i. I bought it in spring 2002 right when it came out http://www.phonescoop.com/phones/phone.php?p=116
So... I've had this sim card for just shy of 8 years.

I can tell you that you don't need a "3G" USIM to use the AT&T UMTS network. They way you're supposed to build a 3g network is by requiring 64K or better encryption on SIM cards. 2G Sims are 32K. AT&T, being the lazy cheapskates they are hacked it into their deployment so that they didn't have to give everyone new cards. It's stupid because they tell all their front line staff to give people new cards anyway.
In my years working for them, I can count on one hand the number of people who have had 3G issues "caused" by a 2G card. In all of those cases it was probably a coincidence. I. Fact I never had any reception issue fixed by a new card. OTA updates? Yes, of course. You don't need to waste your time fetching a new card. Just a phone call and it's done.
So if you're concerned, have a customer service agent update your SIM profile. A new card is a waste of time, the only time you might see a benefit is when changing a card triggers the OTA sim update.

Interesting... I know that SIMs very rarely are the true source, and the only time I had heard of it being so was when people had a 2G SIM when using a 3G device; ie the 32K versus 64K encryption. I thought there was no way around it, for technical reasons beyond my knowledge base. My limited understanding was that the 32K SIMs were missing certain technical protocol for a 3G network to recognize them as part of the 3G network, essentially.
I work for a carrier, btw, and am one of the few sales agents in my area that even knows how to refresh services and what not... actually, I used to have to call up CS and explain to them what needed to be done until my manager gave me the power to do it myself.

I stopped in Tmobile today and they replaced my SIM for free since it was nearly 8 years old (and was saying Vstream, which was annoying). Pretty sure it was a 32k sim. I didn't think I was having 3G/2G connectivity issues, but I'm pretty sure after I got the new SIM in there it started locking onto 3G signals faster and stays there steadily. I noticed it mainly on my train ride home where I would regularly drop to 2G... seemed like it didn't happen nearly as much.

I gave mine to my friend when I picked up the P900. He's gone through another phone since then (treo 650... he managed to put it in the clothes washer within 6 months of getting it) and is now back on the T68i.
Those SE phones are REALLY solid. I've always had a great experience with them, I just got sick of importing them to the US (and in the case of the P1i, not working on Tmob's 3G network.. bastard)... of course they announce the X10 coming to the US on Tmob like a week after I get the Nexus... ah well.
But.. yea.. T68i... one tough little bastard of a phone. The original battery is finally starting to not hold as good of a charge. Not too shabby for an 8 year old phone that's been used almost every day.

HD2 (T9193) & AT&T Microcell anyone?

Hi all,
I have an HD2, T9193 (Telstra model), running Artemis v9.0 & radio 2.09. It works nicely with AT&T here in the US (including 3G), except for coverage in my house (I know - you're all shocked that AT&T has coverage issues ). Anyway, I decided to buy an AT&T Microcell to improve things here at home, but my HD2 doesn't seem to want to connect to it. Since the HD2 isn't an official AT&T phone I had to use my wife's phone (my old AT&T Fuze/HTC TouchPro) to set up the account. The Fuze seems to be able to connect fine (5 3G bars all over the house). I added my HD2 cell number to the Microcell whitelist and went through all the resets etc. that they recommend for troubleshooting, but nothing seems to work.
The only thing I can think of is that AT&T isn't licensed for 850MHz where I live (west of Boston), so the Microcell is only configured for 1900MHz on 3G, which isn't supported on the T9193. As I understand it AT&T uses the GPS location data they get over the network connection to configure the microcell.
Has anyone else had any experience with this setup?
Thanx.
John
same problem
Ive had my HD2 (T9193) for a few days and have no luck connecting to the 3g microcell, let me know if you haveany luck.
I am in california btw
Ditto
Im in PA and spent over an hour with tech support yesterday trying to get it to work. I'm returning the unit today and exchanging it for a new one per their advice. If the new one doesn't work I'll be giving up.
It wont work
Ok, I got a new one last night and again spent 2 hours with support and I couldn't get it it to work. I don't know why it wont. I'm giving up till someone can post some sort of voodoo to make this work.
Is ATT broadcasting on 3G 850 where you are?
I also just spent a long time on the phone with AT&T enterprise care. They couldn't get my HD2 to work with a micro cell. Their thought was that the micro cell was using 1900 because this market is an 850 market and the micro cell might be configured to avoid causing interference with other users. Of course, this was conjecture. I'm going to test the micro cell at the office tomorrow where I have access to other phones to test with.
If you're able to test with other phones, read up on the various test apps that are out there so you can clearly read what the microcell is broadcasting on. E.g. the fieldtest mode of the iphone, theres an old network details app for winmo, etc.
Att Razor, Att Samsung Eternity both work on Microcell but not my HTC Telstra HD2
IME not registered with ATT could be the culprit but ATT would slap $40 data plan to register it.
A listing exclusive for HD2 for now until work around.
Kokkos
I tested with an old Samsung BlackJack and it saw the microcell immediately when using my SIM, even though AT&T still had my HD2's IMEI registered. I moved the SIM back to the HD2 and cannot associate with the microcell.

What do you mean by this? What is a "listing exclusive for HD2," how does one get it, and does it really allow the T9193 to work with the AT&T microcell?
AT&T responds...
The tier-2 AT&T guy who was helping me last night just called me back. He did some more checking after we spoke and learned that the AT&T Micro Cell is configured to work only with AT&T-sold devices, not unlocked devices used on their network.
He pointed me to page 7 of the User Manual where it says in the Performance Highlights box, "Supports AT&T 3G wireless phones and devices." Apparently, this is to rule out non-AT&T-sold 3G devices.
I suspect that changing the IMEI or ESN or whatever the "unique hardware identifier" is might work, but I'm not willing to screw with my HD2 to find out and discussions about that kind topic are frowned upon on XDA.
My Micro Cell is being returned as it doesn't work for non-AT&T devices.

Again... if you could load up a field test app that would be great. For the BlackJack, punch in *#0011#, see if you can find the frequency. If not, try browsing to Windows/Test Mode/Test Mode.exe, look for the frequency. Lastly, try http://forum.xda-developers.com/showpost.php?p=2219019&postcount=2

I'm not convinced. AT&T would put that down to differentiate between their 3g vs. Verizon, et. al.; not to differentiate between devices they sell and devices that are compatible with their 3G. Further, the amount of 3rd-party-but-still-3G-compatible-devices out there are extremely low relative to everyone else, particularly those who buy 3rd party phones and are stuck on EDGE. It just wouldn't make sense to write down that line and have it mean that - it comes across as extremely nit-picky. The only worthwhile carrier that has 3G overlap is Telstra, and I can assure you the number of Telstra 3G phones stateside are rounding errors.
It's possible that it only supports valid ATT IMEIs and there's a footnote in some internal technical document, but it's also possible it's just broadcasting on 1900 3G for all of you . Can you escalate beyond tier-2?
I think the problem is the lack of 1900mhz band on Telstra phones. My Telstra Touch HD will not connect to my microcell, but my unlocked Nokia E71 and N97 mini have no problem. Sad since the microcell gives five bars throughout the entire house!

Wow, great post! N97 was never officially released on ATT but yet it works. The microcell is supposed to be able to use both frequencys (850 or 1900), but from this thread, it seems to prefer 1900? Maybe manicotti can get a Tier-3 rep to throw a "force 850" switch.
I also had both an E71-2 and N97 Mini using Microcell today and they worked fine, as long as I didn't move. I'm having problems with both Nokias keeping a signal and I tried the Microcell to see if it would fix it. It didn't. They both dropped calls when I went outside and had a path to the local tower. Iphone worked flawless with and without MCell.
Cheers
AT&T speaks
Our rep got back to me on Thursday. Unfortunately, it looks like no micro cell for my HD2 in the Philadelphia market.
She wrote "Regarding the micro cell, it's not going to work for the device you are using, but it's actually not due to it being a non-AT&T phone. I have been advised that activation of it is not based off IMEI. It is not picking up your device because the MicroCells in our market are purely 1900mhz, they will pick up any device activated with an AT&T number with 1900mhz. So, if you get, have or use a device with that, the MicroCell should be useful,otherwise it will not be."
I have asked if there is a "force 850" setting and why the micro cell uses 1900 here? (My guess is that the microcell always uses the "opposite" frequency of the market it's in. Of course, the first tech guy that I spoke to told me the exact opposite, but he's the one who came up with the IMEI thing and he said it as a certainty rather than as a guess.)
OK, let's get a few things straight.
I have the same issue, a T9193 and a microcell.
When you enter phone numbers online that will use the microcell, AT&T's computer sends the IMEI number associated with that phone number to the microcell.
Since my T9193 IMEI is not on AT&Ts network, the microcell cannot "see" the phone....it is looking for my old Tilt2.
When they entered the IMEI number for my T9193 into AT&Ts system, it told them it is a 2G phone. Now, I took a chance on this as I may not even get 3G from an AT&T tower anymore.
However, the good part is my microcell MIGHT recognize my phone.
I will test later this week (I am traveling) and revert with the results.
Well two things...
1. Thank God for you guys...I was pulling my flipping hair out on this. Same issue as the rest of you and no luck. More than one unlocked phone and a few ATT handsets all work great (including my family and friends). Just my Telstra HD2.
2. How much does this suck? If anybody figures out a way to make the Microcell operate on 850 (assuming the hardware that Cisco ships them is even capable) please reply on this thread.
HD2 T9193 and AT&T micorcell NOT wokring even with proper IMEI number
Good day,
Unfortunately I am in the same boat with my HD2 T9193 not working with the microcell from AT&T.
I called AT&T support and had them update their records to reflect my HD2's IMEI (they had my HTC Athena IMEI on record). Rebooted my phone BUT no joy. My family all have iPhone’s (3GS and 4) and they pick up the M.cell connection immediately.
So I guess the microcell transmits at 1900 not 850 and I am SOL.
Anyone have a solution for us HD2 users, please don't hesitate to share the news.
;(
Thanks,
anyone ever get their HD2 to work?

Can only get EDGE

Just got the Atrix. Moved my SIM card from HTC Aria which was doing fine on HSPUA and 3G. In the Atrix it will only give me Edge. I am sitting in the same location where I always get a good 3G or HSPUA signal. Have no idea what is wrong or how to correct.
As far as I know ATT needs to do some provisioning on your account to enable 3G(What they call H+/4G bull****).
Most of the time I see the H+ icon, but sometimes the device will disconnect from the network and reconnect. (never happened on my Captivate) and this has not happened during a voice call [yet]. Sometimes I'll see EDGE also.
A sales rep told me yesterday new SIMs would be available, not sure when.
Moved to general as not android development
You don't need a new sim, but your plan does need to be provisioned properly for hspa+. Call care and give them your imei. If you have unlimited you can keep it.
Did you get your data plan changed when you got the phone? When I was upgrading there were a few problems in store and they had to call ATT corporate to get it working.
Rooted/ROM Captivate
Rooted Atrix
att needs to come off the pocketbook and start expanding their coverage, verizon is way ahead in my area
