3G on O2 Exec

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?

3G Signal when using regular SIM card

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.

3G network for O2 Mini?

Hi,
I'm just wondering if the 3g network/simcard will work on the O2 Mini?
This network is in Australia, so for those in Australia knows please let me know.
Cheers

im not sure, i dont think itl work cause the 3G simcards use a different voltage or something, you can use normal sims in some 3G phones but not the other way round...

3g
I have Orange USIM (3G) sim card and its workinhg on Magician without any problem

Some 2G SIM cards can also be used to access 3G networks and 3G services(these type of sim cards is sometimes used, for example in 3 Hong Kong). Some 3G SIM cards (like the ones they have on 3 Australia) are just 3G sim cards, meaning they wont work on 2G phones.

3G needs a special technology which is not available in mini' hardware. Mini users have to just stop with what we already have as they wont even release a WM5 i think so.
However to use 3G effectively you need a cam in the display's front!

Are you able to download at 3G speed? Pointless having a 3G simcard if you can't go faster than GPRS.

If a phone doesn't support UMTS then you won't get a faster speed than GPRS (or EDGE) no matter what sim you put in it.

GPRS and 3G SIM

Can a regular SIM work on a 3G network? Or to be able to access 3G, does a 3G SIM need to be used? If so, can a regular SIM's info be copied over to a 3G and it will work?

Hi
If services provider supports 3G than only thing u have do is to call the services
provider and subscribe for same . I think no need to change the SIM...

Only one sim works out of the two!?

I have an OP2 OOS Version 3.5.6. My two sim slots are also filled up with two sims. So the Problem here is Only one of the Sim works at a time. Suppose if i keep the PREFERED SIM FOR MOBILE DATA as SIM 1 , the network of SIM 2 goes off and only SIM 1 is active.Vice versa . Please help me and as far as i remember i did not configure any unneccesary things. I am just noobin these stuff.TIA

You can't use two 4G SIMs at the same time.
The SIM not set as the primary (data) SIM can only connect to a 2G network.
It's always been like this on the OP2

I mean't to say that Vodafone is 4G enabled Sim. It is not mandatory that it should work only on 4G.
Whereas JIO is a Network Where 4G is Mandatory. BTW it was working fine for the past three months without any issue.
And I even tried Having Airtel as the 1st Sim and Vodafone as the 2nd sim (Vice Versa) it doesn't work..
I thought if i Factory Reset the phone the problem would be gone, but it didn't ! Probably i have to go to a Service Centre

If your JIO SIM is the primary SIM and Vodafone have a 2G network in your location, the second SIM should be able to connect too.
If it doesn't, something isn't right.
