3G on O2 Exec - JASJAR, XDA Exec, MDA Pro General

3G on O2 Exec - JASJAR, XDA Exec, MDA Pro General

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?

Special 3G SIM cards (USIM) needed for HTC Universal?

http://msmobiles.com/news.php/3965.html
Does anyone have any further information on whether a special 3G SIM card is necessary to use the HTC Universal? If this is true, it is terrible news for people who'd like to use it in the USA.
Does anyone have an email address for a decision maker for one of the US carriers (T-Mobile USA, preferably)? Maybe if we send some rational emails, they will decide to pick it up.

It will be necessary to get a new simcard to work on a 3G network... though the Universal will work with any sim card without the benefits of a 3G network (i.e. if you put a 2.5G sim in you will be able to use GPRS in it etc)

I have an Xda Exec on evaluation. I can confirm it works with SIM as well as USIM, without issue.

Pls tell us more...about USB Host fuctionalities etc... battery life...Wi Fi..Bluetooth.Can we listen songs over Bluetooth Headset...?
Any issues related to twisting and turning of screen...Pls

If your carrier offers a 3G network you can get a USIM for no money - or the cost of the SIM so you can access the UMTS network.
SIM - lets you access a GSM network (or an iDEN network)
USIM - lets you access a GSM and a UMTS network
RUIM - lets you access a CDMA network - in theory GSM networks too for roaming (mentioning this for brownie points lol )

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.
Thnaks

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.

O2, Exec upgrades and 3G

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 suppose I'll have to change my name to 3Goldry soon...)

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.
rgds

£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.

There's no such thing as a 3G SIM.
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.

1 SIM @ 4G (DATA/VOICE/SMS) while the other @3G (voice) possible?

Can I have 1 sim for data & voice running at 4G, while the other sim for voice & sms only in 3G? Or only 2G supported?
Because I read at 1+3 forum that it can actually do this, so I was wondering if the Axon 7 can as well. I don't see why not, correct?
Has anyone tried this? I'm in the US, and would like to be able to run a tmobile mvno sim (4G+voice+sms) + an international sim (voice+sms) that's roaming on AT&T who will shut down 2G soon.

It's a dual 4G sim slot, so yea you can run it like that.

Go to settings - dual sim settings - network mode and on sim 2 tell it GSM only. It will keep sim 2 on 3g. Also on settings -dual sim settings you can turn off mobile data for either sim. Just put t-mobile in sim 1 and at&t in sim 2, shut off mobile data on sim 2, and tell sim 2 gsm only. Done

Thanks for the info, I didn't buy the device yet; but this makes choosing a device even harder since both can do this now (1+3 & Axon 7).
Until recently this was NOT the norm I believe, best I could find was a dual sim phone with 1 sim @ 4G while the other @ 2G only.

Doesn't GSM-only mean 2G? While both slots are hooked up for 2G/3G/4G, I think only one slot can be connected to 3G/4G at a time, the other slot goes down to 2G.
When I have my Verizon SIM in Slot1 (chosen as data connection) and a T-Mobile SIM in Slot2, using apps like LTE Discovery show my A7 connected to Verizon LTE, Verizon 1x (2G for voice calls), and T-Mobile GSM (2G), not T-Mobile HSPA (3G). When I switch the data connection source to Slot2, it connects to T-Mobile LTE and Verizon 1x (2G), not Verizon EVDO (3G).

Yes I was able to confirm LTE and WCDMA simultaneous operation
Hi! Amazingly, yeah this works...you can have LTE on one SIM and WCDMA 3G on the other (voice only). I tested this with two T-Mobile SIMs and was kind of shocked as in the past it seems like all dual-SIM phones are limited to GSM-only on one of the two SIMs, as has been mentioned above...
But...strangely, this won't work when using a CDMA SIM in slot 1 (i.e., Verizon). I have no clue why...I can definitely confirm that my experience is the same as that stated above by xtermmin - the GSM SIM will be limited to EDGE (2G only) when the CDMA SIM is active as the data SIM. But with two GSM operators yes one can be LTE/WCDMA and the other can be WCDMA/GSM. I'll confirm real quick just to make double sure but I seem to recall seeing this in the specs and was able to confirm it myself. I've attached a screenshot showing this - I have SIM 2 enabled for data as you can see but SIM 1 still shows voice-only on UMTS and thus is not just limited to 2G. I hope they fix this phone so that CDMA SIMs will have this same functionality...for now though I can say confidently that two GSM SIMs can be operated as LTE/WCDMA on primary SIM and WCDMA/GSM on secondary SIM simultaneously...really great news considering all the EDGE networks seem to be on their last leg!
EDIT: Oh - and don't mind the fact that the "Cellular Network State" is shown as disconnected - in slot 1 I have an old T-Mobile SIM just for this test - it isn't active at the moment on an account. But for demonstration hopefully it does suffice as it definitely has the phone connected to 3G service on SIM 1 while having LTE service on SIM 2. Also - I've included a 2nd screenshot to show that with Verizon LTE/CDMA on SIM 1 (shown as carrier '123456'), SIM 2 will be limited to GSM-only on T-Mo...really weird - not sure why this limitation exists for CDMA users - I think it's a ZTE bug as simultaneous CDMA 1X and WCDMA is possible with T-Mobile as the data-SIM.

Yeah for sure...I love the phone and all but I really hope ZTE will just fix these annoying CDMA bugs already...Seems like they could fix this stuff with or without Verizon's approval - from the beginning they've kind of hamstrung CDMA and I've never really understood why. Another bug I noticed was that when switching calls to the T-Mobile SIM, VoLTE has to be kicked into gear by toggling the VoLTE toggle and sometimes even putting the phone into airplane mode for a second...from what I've heard this is a unique problem to CDMA use as well.

Actually, worse than I thought...but only a bit

Thanks for the info. Has this issue been sorted out to your knowledge? We livein 2 different regions, but would only consider getting the Aussie release of this phone this month if it can seamlessly handle 4g/3g, using 2 SIM cards where both are capable of LTE. Will this work? Does it automatically switch data to SIM 2 in order to take 3G voice call, or does it temp. disable data on sim 1 (4g) to allow SIM 2 call?

Hi - I just tried this and here's what I found:
If active data is on SIM 2, a call to or from SIM 1 is possible on UMTS (WCDMA 3G) but this will terminate the LTE connection on SIM 2 for the duration of the call. However, a call on SIM 2 will not be a problem for data unless SIM 2 is on EDGE or less...on UMTS or LTE (i.e., a VoLTE call) you'll still have data during the call.
If data is on SIM 1, a call to or from SIM 2 is only possible on EDGE!!! I didn't know this! I guess SIM 2 will always be GSM-only if SIM 1 is the active data SIM. And also - you will lose LTE data on SIM 1 if you receive or place a call on SIM 2 EDGE/GPRS.
So...it looks like the situation isn't as good as I'd hoped - if 3G calling is necessary on a particular SIM card at all times, that SIM should be placed in slot 1. And it'll work well even when SIM 2 is the active data SIM. But, if you need 3G calling at all times on both SIMs, you may be out of luck.
Also, the Axon does not seem to allow you to change the data SIM in the middle of the call...in this scenario, SIM 2 was on LTE and was the active data SIM, and SIM 1 was on UMTS (calls only). I made a call on SIM 1 and then changed the data to SIM 1 to try and get 3G data during my call...but it didn't connect to data until I hung up the call...so it seems that the service state gets frozen when you make a call, in a way.
I hope this info helps...seems like kind of a mixed bag, unfortunately.

Thanks for the. That's pretty backwards by ZTE. Makes no sense. SIM 1 and 2 need to work the same way regardless of WHICH SIM had the 3G incoming call and which had 4G data active at the same time. I read the above as SIM 2 can be 2G only, or is the main SIM for 4G data....so 3G calls can be taken on SIM 1. Yep, backwards!
Axon hasn't sold me. Audio on a phone is important, but the HTC front facing speakers get easily clogged, then it looks horrendous. I'm favouring one of OP3T (as i believe this too has unlocked bootloader and root), or worst case - LG v20 or G5 dual...but neither will be given unlocked bootloaders.

So, I just tried it again and it looks like I was able to achieve a UMTS 3G connection on both SIMs even during a call on SIM 1...perhaps my initial test was in error somehow...not sure. But it looks like dual 3G is possible after all...there may be hope!

Are you sure both are running 3g, because I have had devices that always showed 3g even when connect to 2g networks, really need to test with an app the can see both sims at the same time like network cell info mini.

Yes I'm sure. I was using LTE discovery and the Settings --> Phone Status...not just the signal type indication. It can run dual 3G UMTS and/or HSPA+.

Sure thing. Just to make double sure, I just put my FreedomPop (AT&T) SIM in with my T-Mobile one and set both to WCDMA...And it's confirmed that dual 3G works fine (see screenshots below). So you should be ok! AT&T has decommissioned 2G completely so the fact that I could sustain a dual T-Mobile/AT&T connection when T-Mobile is active for 3G data should hopefully prove that the Axon 7 can get dual 3G. One caveat though - with a Verizon SIM in slot 1, slot 2 is still 2G only...So you will be limited to 2G in slot 2 if you have a CDMA SIM in slot 1 which is data-active. But two GSM SIMs should be ok. Good luck!

So Awesome, does anyone if the same is true for the new ZTE Blade v8 Pro, I sure hope so as I am looking to add both of these to my collection, Using prepaid H2O wireless for calls and text and FreedomPop LTE or Global sims for data... What would be the best setup for that data ( FreedomPop ) on sim 1 or sim 2. H20 is a AT&T MVNO

The only limitation vis-a-vis SIM 1 vs. 2 slot I know of when it comes to GSM SIMs relates to WiFi calling... You can only get WiFi calling on SIM 1. But that shouldn't matter for FreedomPop or H2O I would think so it shouldn't matter. Also, CDMA SIMs only work in slot 1 but of course that should affect you either. So either slot should be fine I'd think!
