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.
I've just got an Exec as a free upgrade to my beloved XDA II so I phoned O2 to ask about their 3G service.
In short, if you get an Exec from O2 you should also be given a new 3G SIM for free. If you haven't, call them to say you haven't and they'll send one. No reconfiguring of the Exec is necessary (they say). I'm guessing this doesn't apply if you're a pre-pay client, but who knows?

I don't think a new SIM is required for 3G access... I had a Vodafone Pay&Go SIM well before I got my V1640, and it works on UMTS.
Yes you do require a sim that is compatable, although it is possible your existing one will support the UTMS, if not simply call in to the O2 shop and they will give you the SIM for free, activate it and away you go....
Huge bills - stupidly expensive access charges, but a super quick connection - oh - and did I mention the battery life, UTMS kicks the cr*p out of your battery, I have seen mine decrease even when connected to the car charger - Mike
some theory
3g requires a thicker sim card. You eill not be able to use 3g band with a standard gsm sim. hence no video calling, etc.
its a fact, ie - its a standart.

3G is a thicker SIM? I've not noticed any difference with my T-Mobile SIMs..?
O2 have different SIMS for 3G and GSM. The 3G SIM has some extra information on it which means that a GSM SIM in a 3G phone will not allow 3G data.
I went into an O2 shop and they charged me £10 for a new 3G SIM which they then registered to my account and threw away the old one.

£10 for a new SIM? That's a joke! I might just go back to Vodafone then in that case...
I just had this with Orange.
I bought a SIM from a market stall for £5 thinking that it would be cheaper than going to Orange for it.
I put it in my Uni, got it all registered and everything was fine until I asked 450 why I wasn't getting a 3G icon.
I had to go to the Orange shop, pay another £5 for a SIM (USIM, 3G SIM) and then ... The fun started.
I put £20 on the USIM when I bought it, it was pre-activated. I took it home, phoned 450, got them to change the number from my old SIM to the new one. I asked if the £20 would be credited accross and he said "yes, within 24 hours".
I waited and it didn't appear. I phoned 450 and the nice gentleman in India told me there was sweet FA he could do to help, go see the Orange shop.
I went to the shop and they told me that ev erything had been done wrong, that they shouldn't even sell USIMs without a new 3G phone to go with it.
I got my £20 back though and am now fully 3G (when in coverage).
The USIM isn't any thicker than the 2G SIM, but it is a different color.
So you're saying that the orange SIM card was meant to be free? Or were you not meant to get it at all?
I think the virgin 'normal' free sims can be enabled to be 3g simply by sending a message to 80310 with the word “Video” but o2 use special seperate 3g sims. From what I understand there is extra capacity on the newer 3g sims but for current 3g services we don't need them hence why virgin's can be enabled.
I have o2 sim and am planning to be off on my travels so am in the process of setting up my universal (xda exec) to use a virgin sim in this as you can roam in Japan only on a 3g sim.
Let us bare in mind that these most extreme cases are pay as you go deals where its "not subsidised"....
If anyone puts some marketing sense into it it will be clearer to understand what all the comotion is about.
Eventually all charges for sims etc on paygo will be waved.... for the moment its a matter of choice.

Yes there are different SIMs available (with more on-board memory) but at the end of the day they all have to fit into the same SIM shaped hole in your phone.
The handset and features on your account determine whether or not you can access 3G.
actually there is a specific SIM for 3G. It is same shape and size but does not work in older 2G phones..... However, 2G SIMs all work in most 3G Phones

Not entirelly right m8...give it a try if you have one and you will see I have my o2 rg sim and works fine on other 2g phones...that also goes for another PAYGO 3g vodafone card that i got hanging around...obviously when it comes to three uk its a diferent story since they do not offer a gsm service and rely on 02 lines where there is no coverage from them and this costs them money.

need help to set up a prepaid t-mobile sim setting or a .cab or some thing
Basically, I'm grandfathered in on a great plan with only a gig of data. I'm also grandfathered in with another company for unlimited data, no voice service.
Is it possible to use one sim for calling and the other for data. And when I get into areas not covered by the unlimited data sim switch over to the first sim with better coverage?
Thanks for any advice.
You should be able to set the first Sim for voice calling and the second sim for mobile data from settings, connections, dual sim
Yes!
I used my Vodafone sim for data and everything else goes through my EE sim.
Once you have the second sim in, slide down from the top and you'll see options for SIM1 and SIM2
