CDMA Iphone 4S and UMTS/HSDPA/HSUPA?

Quick question, if I purchase an off contract Verizon iPhone 4S and get it SIM unlocked from verizon, does this phone support the UMTS/HSDPA/HSUPA (850, 900, 1900, 2100 MHz) bands? My understanding is that it does support the GSM/EDGE bands, but I'm a little unclear if it does the other ones or not.
My plan is to purchase it off contract and have the option of using it on Verizon or AT&T's 3G networks if needed. (Not at the same time)
Does the AT&T and Unlocked 4S only support the UMTS/HSDPA/HSUPA (850, 900, 1900, 2100 MHz) bands?
Thanks

Verizon does not unlock iPhones, even when off contract. The SIM socket and GSM support are for international roaming only. If you want to use an iPhone with GSM carriers, you need to purchase an unlocked GSM version (AT&T doesn't unlock iPhones either).
The GSM frequencies and standards the iPhone 4S supports can be found in the tech specs:

UMTS HSDPA HSUPA for Macos X recommended working modems? Failures in 10.5.2

I have a HUAWEI E800 with MAC driver, but it ***** in 10.5.1 and fails in 10.5.2.
If you leave the card in its slot and use sleep mode:
10.5.1: Card is disabled until reboot.
10.5.2: Complete USB & sound system failure (incl. external Logitech mouse) see system log below.
The workaround is to remove the card before any attempt to put the computer to sleep.
Can anyone recommend a better card/manufacturer?
I was thinking of a Novatel Merlin X950D 3G HSUPA HSDPA 7.2 Mbps ExpressCard.
Has anyone experience with their Leopard support?
Thanks.

It appears this issue has been fixed in any OS upgrade since then.

Is it possible to change your cdma iphone 5 to a gsm carrier, and then back to your previous cdma carrier?

I'm using StraightTalk right now and am wanting to try out H20. I know my iphone 5 is gsm unlocked so the switch to the gsm H20 Network should be simple enough. I'm wondering though if for some reason I don't find H20 a good option can I switch back to StraightTalk on my CDMA network.

If you have a CDMA iPhone 5 (in the USA, model A1429), and the GSM slot is truly unlocked (not just unlocked for international use) then you can use it with a GSM network. You should be able to go back to the same CDMA network it was sold for - in other words, you cannot change to a different CDMA carrier as the CDMA carrier is permanently locked in firmware and cannot be altered.
But make sure the GSM SIM slot is truly unlocked. For example a USA Sprint iPhone 5 could have the GSM SIM slot unlocked for international use, but it would not accept a SIM card for any GSM carrier in the USA, only for overseas carriers. I'm not sure what Verizon's policy was with iPhone 5 phones (with the new iPhone 5s or 5c, Verizon phones are sold with no lock of any kind on the GSM SIM slot).

IPhone 5 and Satellite GPS

Everyone, for a long time I have been wanting to move to the iPhone, however due to the lack of Satellite and WAAS based GPS, i have not. So I am wondering... Oh, please, oh please, oh please, does the iPhone 5 have Satellite based GPS?
If not, does anyone know why Apple will not add this feature to their radios.
thanks

By "disabled the radio", do you mean put it into airplane mode, which disables the GPS.
http://support.apple.com/kb/HT1355?viewlocale=en_US&locale=en_US
Some info on the iPhone 4 and 4S:
GPS
The iPhone 4 previously used a BCM4750 single chip GPS receiver, and shared the 2.4 GHz WiFi antenna as shown many times in diagrams. We reported with the CDMA iPhone 4 that Qualcomm’s GPS inside MDM6600 was being used in place of some discrete solution, and showed a video demonstrating its improved GPS fix. I suspected at the time that the CDMA iPhone 4 might be using GLONASS from MDM6600 (in fact, the MDM6600 amss actually flashed onto the CDMA iPhone 4 includes many GLONASS references), but never was able to concretely confirm it was actually being used.
MDM6610 inside the 4S inherits the same Qualcomm GNSS (Global Navigation Satellite System) Gen8 support, namely GPS and its Russian equivalent, GLONASS. The two can be used in conjunction at the same time and deliver a more reliable 3D fix onboad MDM6610, which is what the 4S does indeed appear to be using. GPS and GLONASS are functionally very similar, and combined support for GPS and GLONASS at the same time is something most modern receivers do now. There are even receivers which support the EU’s standard, Galileo, though it isn’t completed yet. This time around, Apple is being direct about its inclusion of GLONASS. The GPS inside MDM6610 fully supports standalone mode, and assisted mode from UMTS, GSM, OMA, and gpsOneXTRA.

I have an AT&T iphone 6 and want to give my AT&T 4 to my wife but she is a Sprint customer. How involved would it be to convert my 4 from AT&T to Sprint?

I Have an AT&T iPhone 6 and wants to give my AT&T 4 to my wife but she is a Sprint customer. Is this possible and, if so, how involved is it to convert my 4 from AT&T to Sprint?

Likely not possible.
Sprint is a CDMA carrier which typically do not support BYOD (Bring Your Own Device) .
You will have to ask Sprint if they can offer service on a unlocked GSM Phone that does not have the CDMA chip.
Its unlikely they will though. But if they do, you will need to request AT&T unlock your iPhone so you can insert a Sim card form another carrier into it

Iphone 5 and IOS 6.0.2 is draining my battery! (new thread)

Well, apparently Apple doesn't want us to talk about this -- They locked the previous forum I had created after 217 posts and 16k views?
I'll assume there is some other Apple Forums rule that I don't know about that would cause them to do that instead of trying to stifle the reporting of this problem? It was clearly generating many posts that show a correlation between IOS6.0.2 and battery issues.
To summarize... I was having significant WiFi issues on all my apple products (several Iphone 4's and and Ipad2) with 6.0.1 - all the same issues that have been reported on these forums thousands of times. I was excited to see 6.0.2, hoping it would correct the wifi issues for my iPhone5, at least. Unfortunately, not only did it NOT correct my wifi issues, but now my battery is draining about 5x compared to before. I can barely get through a day of batterly life with minimal usage whereas before 6.0.2 I was easily able to go 2+ days.
An apple representative called me today (actually he tried very hard to call me for several days.) I was appreciative of the reachout (saw my other post) and was hopeful they would be willing to help me. The guys was very nice, but it truly felt like he was reading a script and was more interested in getting information from me. The only advice he ad for me was to back up my phone and then reset it to factory settings (like new) without using any of my previous apps, mail, etc. He wanted me to do this "for a day or two" to test it and see if the problem persists. Then, if the problem is gone, we can work together to restore apps/settings one-by-one until we find why the problem is there. In other words, they have no idea what is causing this problem, and they want to use my time to help them figure it out.
Ironically, I was able to watch my battery indicator drop several percentage points while I was on the phone with him for about 20 minutes.
When he asked if I would do the restore and/or load profile software on my iphone to track my usage, I said no. I shared with him I'm simply out of time and energy -- I have logged over 40 hours trying to debug these wifi issues (I'm somewhat tech savvy and figured I could just plow my way through to a solution with my router/security settings.) When I realized that these issues are all IOS driven, and now the battery issues, I find I've had enough.
Maybe I'll go return this Iphone5 and ask for a replacement. However, I'm also seeing other posts saying that did not solve their problems.
We are talking about wifi and battery life. This is not new technology.
If IOS 6.1 doesn't correct these issues, it's probably time to buy an Android.
Please keep posting things directly relevant to BATTERY issues with iPhone5 so that this thread can stay on task and bring to light the correlation between 6.0.2 and the battery. Maybe Apple will care about their loyal customers, acknowledge the issue, and let us know how much longer we should wait for 6.1 to fix the issue before it's too late and they start losing their fan base. No information from Apple is only exasperating the problem.

I had the same experience with a new iPhone 5 that I bought last week. Did not have a chance to measure battery life before the 6.0.2 upgrade installed but I set up my phone exactly like my 4S and immediately started running out of power after short periods. Went to Xmas get together with fully charged 5 and 4S. Heading home the iPhone 5 shut down for low battery and the 4S had 65% power. Both phones had two half phone calls on then and no data usage.
That night I fully charged the iPhone 5 and, without lighting it up, put it on my night table. Next morning I picked it up and looked at battery indicator and I had 42% charge with NO activity!
Tried it again next night and wound up with 37% charge. (Slept longer).
Today I called the carrier and reactivated the 4S. Took the 5 to Apple Store and they kindly gave me choice of new replacement phone or refund. I took the refund. Uniquely, the Apple Store said it was Verizon CDMA phones that were coming back.
The are other strings on this with temporary solutions, but from my experience with 7 firmware changes on an HTC 4G phone the problem will continue because the solution will be hardware caused. We are in the days where RTM means Rush to Market - not Release To Manufacturing.
I fear the only solution is to either wait for the next model (I did not notice a really major change in performance over the 4S in LTE heavy Seattle area) - or switch to another manufacturer.
It might be useful for these forums to indicate if you have a GSM or CDMA phone to see which have more problems.

Sprint/CDMA iPhone 4 into iPod touch?

I have a Sprint (CDMA) iPhone 4 that is due to be deactivated on 2/26. Ive already erased all my data, removed it from my iTunes account, turned off iMessaging etc. to get ready for resale but maybe I'll just keep it as an iPod Touch.. Each of the walkthroughs I've read talk about having an active SIM card when going through making it into an iPod but being a Sprint phone there is no SIM card. Is there a specific way to go through setting it up, should I wait til its actually deactivated, or should I just go through like I'm setting it up as a phone and just put it in airplane mode?

I am not sure but I believe that if it has a SIM card in it and you connec the phone to itunes it should appear in the list of devices in the left margin of itunes

Why was I sold a CDMA iPhone in the UK?

So I bought an iPhone 5 about 1 week ago. I just checked the model identifier and it's 'iPhone5,2'... This is the CDMA iPhone 5.
I would have expected to have been sold an iPhone5,1 which is the International iPhone 5 (along with GSM in USA).
Everything works fine, of course, but I am just curious.

The short URL appears to bounce you on to
http://itunes.apple.com/gb/podcast/u...447?i=85228289
and obviously this isn't a valid Store URL. I've no way of further checking the short URL. Possibly you don't: I should try making another one.

Can i use a GSM sim on a CDMA iPhone 4S after a CDMA factory unlock?

I just got an iPhone 4S as a gift from my cousin in Canada. Upon trying to get a factory unlock for it i was informed that it is a CDMA phone. If unlocked can i use a GSM sim with it? Am in South Africa.

There is no way to "unlock" a CDMA iPhone. Only the sim slot can be officially unlocked, and that can only be authorized by the carrier the phone is locked to. None of the Canadian carriers will authorize such unless you are a current/former customer who used the phone on their network...obviously, not you. Thus, there is no way for you to get the sim slot unlocked. Send it back to your cousin & have him/her get the sim slot unlocked.

GPS issues on CDMA iPhone?

i'm getting pretty frustrated with the GPS issues with the CDMA iPhone.
i cannot maintain a consistent lock with GPS for more than a few minutes.
on Navigon: GPS looses every 4 minutes or so, and the speed indicator never shows a consistent speed, it'll show 60, 60, 0, 58, 58, 0, etc... then it will loose lock and take quite some time to get it back.
on GPS Drive (motion GPS): it will drive for a few more minutes, but then loose lock for minutes at a time.
on the GSM iPhone, i never had these problems.
anyone have any suggestions or fixes for the problem?

I feel your pain. I have the same issue with my CDMA iPhone and there have been numerous threads in regards to it and there has never been any acknowledgement from Apple that an issue even exists. Some people have noted that doing a hard reset of the phone, or restoring your phone from a backup have lessened the issue, but to my knowledge nobody has posted a guaranteed cure. One thing that I have noticed that if you're using bluetooth in your car, turn it completely off (under settings/general/bluetooth) as a test and then try your GPS apps again. The problem seemed to occur significantly less. Another noteworthy point is that the Maps app that comes with the phone doesn't seem to have this problem. Please comment back in regards to bluetooth and Maps with your results. Also for all it's worth, you can send feedback to Apple in regards to this. I did so, but never heard a response, but none the less that's the place to also post issues such as this. Here's the link...
http://www.apple.com/feedback/iphone.html
One think of interest is that it is an assisted GPS. It uses WIFI, cell towers, GPS and who knows what else to pinpoint your position. And there has been some privacy concerns (a little overblown if you ask me though) over the data collected by Apple to pinpoint your position. Apple has admitted to discovering bugs in iOS 4 in regards to this and has indicated that an update is forthcoming to address this. So maybe our problems are related. Keep your fingers crossed!

Portege R500-11K with UMTS/HSDPA/EDGE/GPRS module XP drivers

Hi everyone,
I have some pre-sales question about nice R500-11K notebook.
I would like to install XP pro on this machine. Device is shipped withou XP recovery CD. (model 11C has it)
There is nice collection of XP drivers for R500, so I can install XP manually.
http://eu.computers.toshiba-europe.com/cgi-bin/ToshibaCSG/download_drivers_bios.jsp?service=EU&mode=allMachi nes&action=search&teddProduct=747
Model 11K has unlike another models UMTS/HSDPA/EDGE/GPRS module installed. Great!
What about drivers for this module?
There is no any UMTS/HSDPA/EDGE/GPRS modem drivers listed In the device drivers list neither for Vista or for XP.
So question is, if I want to manually install XP, where I can find the driver for 3G module?
Is the driver component of another driver?
Do anybody know the name and type of this 3G module? I believe module is provided by aint Toshiba vendor.
Do anyone have any experience with XP on R500 11K?
Thank You
Marek

Hmm you are right.
The 3G driver is not available on the Toshiba page
Seems the driver was not uploaded however the Portg R500 was delivered with a *Novatel MSM6275* ThreeG card (Qualcomm should be chip manufacture) and if you want you could try to download the driver from 3rd party site.
Good luck

How could i use internet on cdma iphone 4

i am not able to use internet on cdma iphone 4
is
only through wi fi get connecting.
is it possible to connect through sim network to internet?????????

A CDMA iPhone 4 does not have a sim card slot on it, so no.
If you can't connect to the internet other than through wifi, then contact the cdma provider, which will either be Verizon or Sprint - which cdma carrier is the phone on?
Check this and find out and then contact them, but you cannot insert a sim card into a cdma iPhone 4 because there is no sim card slot.

IPhone 6 and 6 plus conference calling

Hello everyone, I'm waiting on my iPhone 6 plus from verizon to come in and I searched a bit for this answer but no one has clearly answered this. Now I know that the iPhone 6 and 6 plus has the advance 1.0 calling feature on it which we can now do HD calling and as well as 6 way calling but I just have a couple of questions.
1. Is it truly 6 way calling just like AT&T where I can do this with landlines and other networks or is it only with other phones on verizon with voLTE?
2. If I'm already on a call and a second incoming call comes in, am I able to merge that call to the existing line or I have to tell the caller to hang up and then I proceed to call everyone at once like all CDMA iPhones had done in the past for multiple calls?
Sorry if this has already been answered as I tried searching but haven't had much luck. Thanks guys!

Hey there, lilfool4lif3! Thanks for bringing your questions about conference calling to the Forum. I'm sorry that you've had any difficulty getting this straightened out. Although the iPhone 6 using iOS 8 can support conferencing with up to five other callers, this activity is not yet supported while using Advanced Calling. That said, the process if adding a caller while engaged in a call can be done by tapping the HOLD CALL Answer, and then tapping MERGE CALLS. Thanks!

I have an iPhone 4S and currently my carrier is AT&T, but I'm switching to Verizon. Do I have to buy a new iPhone?

Verizon, like virtually all CDMA carriers will not activate a device on their network that was not sold for use on their network.
To activate an iPhone on Verizon it must be purchased either directly from Verizon or from Apple (or an authorized reseller) for use on Verizons network.
On AT&T and all other GSM carrier iPhones (including Unlocked iPhones) the CDMA antenna is disabled.
