I have an MDA that I would like to use on ATT's network, but I hear that they are only using 3G SIM cards now. This is not a 3G phone, so does anyone know if this would work? Would I need a new ROM, or would it "just work"?
Thanks for any and all help!
3G sim works on wizard
Bro-
I use AT&T and I can verify that the AT&T 3G sim works on a wizard...it works in my wizard!
I didn't have to do anything special. Hopefully you have a G3 so you can sim and super-cid unlock fairly easily.
P.S. Go Spurs Go! I do love Avery Johnson, though!
the 3G sim card might work, but getting 3G fast internet won't.
It works. I use a 3G sim as an emergency prepaid number and I make and receive calls/sms/mail/everything fine using EDGE. No different than using a standard SIM.

Hi Folks
Does anyone have a soft copy of the handbook for the Universal they could post or mail me? Love to have a read.
Also, for the 3G calling, does it use a sim or usim?

3G traffic (be it data or video) always require a USIM. If you don't have any, you cannot get onto the 3G network. I'm actually having this issue, as I travel to the UK a lot, where T-mobile has a live 3G network. As I do not have a USIM (since T-Mobile NL doesn't offer 3G yet), I cannot roam onto their 3G network, only onto GPRS...

My operator (Telenor in Norway) enables the customers to use their OLD SIM cards and still have full 3G access!
My SIM card is from 2004, but customers may use cards that go back to July 2000 on the 3G network..
There has been some Over The Air updates, but these might be for something else..
The user only gets a SMS saying: "You SIM card has been updated, please reboot your phone."
So we can use the same SIM on a new and old phone, 3G or no 3G...

Not 100% what you're after, but hope that helps.

Well, I'm using a 4-year-old T-Mobile SIM in my JasJar, and I'm getting 3G access with absolutely no problems...
I didn't think there was such a thing as a USIM exactly? I got the impression that a "USIM" was just a normal 3v SIM card which has been enabled for use on the UMTS network. And that's done by pressing a button at T-Mobile 'Command Centre'...
'3' here in the UK make a big deal about USIM cards, and how you have to have one to use a 3G phone, but that only seems to apply to their handsets, because they put about 800 billion security locks on each of them. In my experience, Vodafone and T-Mobile don't require you to upgrade the actual SIM card at all, and I assume that Orange and O2 are the same.

Hmmm, you learn something new every day... It could be that one can indeed update the SIM to a USIM with a OTA update, I just hadn't heard about that before. I might put in a phonecall to T-Mobile...
Thanks for the heads-up!
I'd better just point out that my last post was entirely guesswork on my part, based on the fact that my old T-Mobile SIM, and my sister's (3-year?)old Vodafone SIM both work perfectly in 3G devices.
In my case, I never even told T-Mobile that I'd bought a 3G phone, the SIM just worked on 3G from the second I put it in, so no OTA upgrade needed? (Of course, maybe they gave us UK customer's an upgrade one night without telling us?!)
My sister got an official Vodafone upgrade to a 3G phone, so they may have done an OTA thingy at the time, but the actual physical card is the same...
So my new Exec turned up today, along with a new SIM card, marked 3G.
Do I need to use this card?
My current SIM works fine in it, but Im wondering if I need to put in the new one, call Cust Services and have it enabled, or can I get the 3G service on my existing SIM?
Depends , the 3G card will allow faster internet connection- if in service area
if in stand gprs area , you get a G at top of screen
if in 3G area you get a U
Does that mean I have to use and register the 3G SIM? As far as I was aware, the SIM doesnt actually provide any functionality - its the service class your contract has?
@CPGOD
3G and GSM SIMs are different. Only with a 3G SIM can you use UMTS (3G services). Please check with O2, they may be transferring your number to the new SIM from the old - which would be a good thing if you want fast data download (max speed around 384kbps)
not true, my voda sim of over two years is now 3G enabled...
@twaddle, you're right it is possible to have a SIM that is GSM and UMTS. Did a bit of research and found SIM cards can function in GSM and UMTS modes. This has not been true for "3" network, however.
I'm not really sure the old SIM can be used to received 3G, I've just upgraded and got my old number transfer to the 3G sim, it works after a few hours. If the old one worked then why would they bother giving out the new sim?
I just unlocked my SPV-M5000 and replaced the orange 3G sim with a regular Vodafone SIM. Much to my surprise the phone after a few minutes of being on the regular 2G network picked up the UTMS network from Vodafone (the provider name changed and the gprs symbol changed from G to U).
The coverage was only 2 bars and I could not make calls on it anyway, so I changed my network settings from auto to GSM and now only the 2G network is found. I was wondering how this could have happen when using a regular non 3G sim in the first place.
I think the best thing is to get a 3G sim anyway from Vodafone. Is this something that vodafone would normally do. I would keep the same number etc of course, I just want a 3G sim instead of a 2G one.

I am running an O2 XDA Exec and a Sony Eric 750i.
Have asked O2 to send me a 3G compatable card for the Exec which presumably will be the same number, not sure if this will automatically invalidate the original Sim or if this can continue to be run in my SE?
Any ideas?
Vodafone does not provide any seperate 3G sims. they just provide SIM cards and depending on the phone they are in they pick up the signal.
The o2 3G sims work in all phones......3G or not so I don't think they are any different. They could be.
But as far as Vodafone is concerned, they donot provide seperate SIMs for 3G/2.5G.
There is no such thing as a 3G SIM.
The clever stuff is done by your phone.
Voda and O2 do it differently.
With Voda, any sim will do.
With O2 you need a 3G sim, which are different to a standard 2G sim. I believe this has something to do with enhanced security. Either type of sim will work in a 2G or 3G phone, but of course you can only get a 3G signal with a 3G sim and 3G phone.
Hi, I have a unlocked Wizard & my T-Mobile contract has just expired, I was just wondering if a 3G sim (3) would work in it as there are some cheap deals on that network? I wouldn't use it for video calls so thats not a problem.
im 99% sure they DONT! however maybe someone there can prove me wrong
I'm using a Cingular 3G SIM in my 8125 with no problems at all.

a cingular 3G sim and a "3" UK usim are not the same, one runs at 3 volts (sim) and the other at 5 Volts (usim)
Aha! More than I knew! I knew it! Thanks for correcting me..

what our american brothers call a "3g" sim and what the network provider called "3" use are slightly different things.... a american 3g sim is simply a normal 128k provisioned with extra services I.e. data and video calling (this is the same way all the gsm uk networks work too) however with "3" being the first 3g only network in the world they choosed to use the next generation of sim card called a usim which don't work in lots of non 3g phones including the wizard. try googling the word "usim" to see wot I mean
Under 3's terms and conditions you are not allowed to use their sim in a 2.5g phone. If you do use one and it works, they will eventually block it and send you a new sim with a gentle reminder that you are in breach of Ts and Cs.
Cheers Chaps, 3 it isn't then!
My O2 UK 3G UMTS sim works perfectly in my Wizard.You just can`t really get the benefits from it (Faster GPRS/EDGE etc....).
Can I use the same SIM that I had in my Wizard on the Tytn? Will GPRS still work on the Tytn?
thanks
It should if you configure the connections properly, I am using an old ATT Blue SIM that I have had for close to 5 years with no problems.
Apparently for 3G functions you will need a 3G sim. I have to replace my 5 year old sim because of this.

Cingular states this here in the USA but I have sucessfully used my TyTn in Atlanta GA on 3G with my old SIM with no problems. I realize you are not in the USA and things maybe different for you but have you tried it first?
