About HSPA sim card

I am in south korea where I am using SK telecom's CDMA network using USIM card with a normal CDMA and HSDPA network.SK telecom has also HSDPA network for iphone users.I cut my normal sim card and tried with my iphone.IT detected the sim card but displays "No network" ans when I used that sim card back to my phone using adapter it shows the network.So to use my iphone in that network what should I do?Should I buy HSDPA sim card or what? what is the phenomena for this?

Phenomena? You are trying to do something that is not really able to be done and I love when people buy these phones and then try to do things like this. Why not deal with what is offered to you?

I am from Australia, i have brought my i pad and i enquired about a sim card to use while on holiday in the uk, i was told it might block my i pad when i return to Australia, is that correct?

Hi
I am Australian and I am in the UK on holiday, I enquired in a VODAPHONE shop about a SIM card to use in my ipad whilst in the UK, I was told it might block my i-pad when I return home to Australia, is that correct?

I used a UK SIMM card in mine when in the UK. When I got back to Sydney I just removed it and put my Telstra SIMM back in. It found the Telstra network and all was well. I'm not sure how it could block your iPad if its not in the iPad when you get home.

Question about swapping SIM cards on a Z10

Hi, everyone, I am a non-Blackberry user who works in IT support. One of my clients uses a Blackberry and has often asked me very complicated questions about how to do various unusual things with his device. At the present time, he is considering switching to a Z10, which would be set up using ActiveSync. He wants to know if he could swap the SIM card without having to go through the setup process again. My client travels a lot, and wants to use a local SIM card on an upcoming trip to a very remote area.
I've not been able to find an answer to this anywhere.
This is his exact question: "I just got it from a friend (ATT version) and I am trying to see if I like it enough to switch to it as my primary phone. Blackberry z10 asks you to sign in with your blackberry world ID when you first set up the phone. Question: Would you have to do it again if you put a different simm into it? With iPhone, it makes no difference so long as the device is unlocked—you can then exchange simm cards as often as you want. Would it be the same with an unlocked blackberry z10 (I know it's not possible with the bold 9900 as System 7 ties your ID to the simm card). In short, in blackberry z10, could you exchange the US simm for another country's simm without having to wipe the phone, etc. "
If anyone can shed some light on this for me, I'd be very grateful., Thanks!

Hi and Welcome to the Community!
The key issues are thus:
Ensuring that the device is truly carrier unlocked
Ensuring that the specific device model is compatible with the radio frequencies/technologies that the desired carrier uses. There are 4 different Z10 models:
http://www.bbin.in/en/2013/03/03/4-types-blackberry-z10-models-fits-better/?utm_campaign=4-types-of-...
If both of those are OK (separate research of the desired carriers would of course be necessary), then it is indeed a simple matter to change carriers. For example, I changed from ATT to TMO by simply changing the SIM...no need to WIPE or anything, and my same BBID came along just fine. You should, however, always obtain a properly-sized SIM card from the carrier -- there are plenty of reports of folks trying to use "cut" SIM cards and experiencing errors.
With BB10, it's actually simpler than with legacy BBs. Legacy BBs used the BIS service, which required receipt onto the device (from the carrier data network) of Service Books so as to activate the various services that the user subscribed to. When changing carriers, it often could be that a latent Service Book from the prior carrier causes issues when shifting to a different carrier...and that's where WIPING and such came into play, so as to cleanse the device so that the new carrier could deliver all of the proper Service Books to the device. With BB10, there is no BIS, and there are no Service Books...so all of that complication is eliminated.
But, as always, YMMV.
Good luck!

TS4429 Reset iPhone 5 and now it says "No Service" and something about a SIM card

Help, please! I basically did a factory reset on my iPhone 5 and it says that I have "No Service" - When I view my phone info, there's not even a number for it. The number says "unknown" ***, HELP. It says that I NOW need a SIM card. It's been working fine without a SIM card, before. Why does it say that? Do I insert a SIM card and then take it back out? I mean, my service provider is Alltel. I was not present when my parents bought me the iPhone, I don't know if Alltel put a SIM card in for the setup and then took it out. When I checked the SIM card slot last night, there's NOTHING there. So, how was it even working before? >.>
These are the things I've done to TRY and fix the problem and it hasn't worked:
1. I've reset the network settings, DID NOT WORK
2. I've reset the factory settings (again) to try out different options like backup to iTunes or iCloud and wifi connections, DID NOT WORK
3. I've turned on and off airplane mode, DID NOT WORK
4. I've turned off and on my phone, DID NOT WORK
5. I've tried multiple online Apple Support steps, DID NOT WORK
Help....................

Thanks for your respons,.
I'm facebooking and emailling everyone to contact Alltel for me. My parents, for example, are just NOT understanding what's going on. They're like "The service is paid for, so I don't know why it's messed up." And, I'm like, I KNOW the service is paid for, that's not the problem. The problem is I reset my phone and now it has NO number on it. The number is listed as "unknown" instead of my actual number with digits. So, I'm pretty sure Alltel can put the number back onto my iPhone, right? I mean, this is ridiculous.

HT201269 what about the SIM card?

I want to replace my old iphone so i got a new phone with no SIM card. If i follow the steps in this discussion (back up to icloud, etc), when do take out the old SIM card and put it into the new phone?

It depends on what you called old iPhone.
iPhone/iPhone 3G, 3GS uses the standard sim card.
iPhone 4, 4S uses the micro sim card.

Question about the sim card

I own the original iPhone and I am getting ready to purchase the 3g. Will at&t give me a new sim card? Or will I have to take my sim card out of the original iPhone. Thanks for the help
Marcus

you can do either, get a new one or keep the old one.

My phone is saying No SIM card installed, when I clearly have my SIM inserted?

My phone is saying No SIM card installed, when I clearly have my SIM inserted. I can't make or receive calls. What can I do to fix this?

Did you already try to remove it and put it back again?
When changing the SIM card, power off the device prior to opening the SIM tray. After you have changed the SIM card for your iPhone you may need to reconnect it to iTunes.
iPhone keeps a record of previously inserted SIM cards, but if the carrier name of your SIM does not show up in the status bar after you changed the SIM you will need to reconnect iPhone to iTunes. If you do not connect iPhone to iTunes after changing or reinserting the SIM, iPhone may not work as expected.
If iPhone does not work with the SIM card after connecting to iTunes, you might need to restore your iPhone. Consult the iPhone User's Guide for more information on iTunes and iPhone.
If your iPhone does not show up in iTunes (on the left hand side of the iTunes window under Devices), please see the following links for assistance:
iPhone: Not recognized in iTunes for Mac OS X
iPhone: Not recognized in iTunes for Windows

If this does not work, contact your provider, maybe your SIM is damaged.

Does iPhone 5 sim card size and shape are changed?

About the sim card size and shape, there are some web sites talk about new micro - nano.....what ever sim cards for the new iPhone 5, I searched the details in the official Appel site there was no any topics about this issue, now I want the truth form any one knows it, is the sim card changed? or it is the same as for iPhone 4 and 4s?

Yes sim card size is changed, iPhone 5, 5c and 5s supports a nano sim which is slightly shorter than micro sim which is used in iPhone 4 and 4s so you have to trim your sim or you can get a new one

Bad SIM Card?

I've read through a couple of the topics that address the connectivity issues with the Bionic, but could the SIM card be the culprit? I had an HTC Thunderbolt before this phone, and we all know the same problem persists on that device, but I find it hard to believe that I'm having the same exact problem on two different phones. I went through two Thunderbolts before exchanging it for the Bionic, so I'm just throwing out that possibility. Bionic is a great phone, but the connectivity issues are killing me.

DStorm169, thank you for your inquiry and that is a great question about the SIM card. We are investigating some issues with the Bionic losing data and hope to have a resolution in the first maintenance release for this phone. Still, if your data is constantly losing data where you can hardly connect, it doesn't hurt to try another SIM card. You can always visit one of our corporate stores or send me a PM with your name & number for a replacement SIM card.

Selling iPhone - w/sim card?

I'm selling my iPhone 4 and am clear on how to wipe the phone and reset. But what about the sim card? Is that something personal, linked to my AT&T account or just generic, allowing access to the AT&T net?

Inacurate response:
Either you do the unlock work and perform a restore on your iphone with your SIM card in from your end before shipping, the remove it before shipping,
OR you ship it with your SIM card to let the buyer perform it (...happened to me twice)
Process to unlock your iphone:
start with a request an unlock to your carrier (i.e. AT&T here - not for Verizon this requires the account holder to perform it with account still active),
1.Request AT&T unlock online at: https://www.att.com/deviceunlock/client/en_US/termsAndCondition
2.Check your status at: https://www.att.com/deviceunlockstatus/client/en_US/deviceunlockstatus_action
3. Perform the restore as indicated below and then see a confirmation screen from Apple ITune when performing the restore.
Completing Your Authorized ATT Mobile Device Unlock
Thank you for contacting AT&T Customer Care about unlocking your AT&T Mobile device.
We have reviewed your request and confirmed that the device may be unlocked.
1. Open iTunes on your Mac or PC and verify that you have Internet connectivity.
2. Ensure the original SIM card that came with this device is inserted in your iPhone.
3. Connect your iPhone using the dock connector to USB cable that came with your iPhone.
4. Backup and restore your iPhone using iTunes. For information on backup and restore, please visit http://support.apple.com/kb/HT1414.
5. After restoring, your iPhone will be unlocked.

SIM card with IPhone 4s

It keeps telling me that the SIM card in my iPhone 4s is not the SIM card associated with my account. They have already disabled my other phone and I have no way to contact them or anyone else. Any suggestions?

I ordered my 4s from apple.com on Oct 7 around 2am in the morning...wanted to be one of the first to get it! Arrived on Friday, Oct 14 around 11:30am CT. When first activiting it I was getting the server is busy error...tried for about 4 hours and never got activated. Called AT&T and they activated the SIM in my 4S which made my 3G stop working. Then I started getting the 'The SIM card in your phone does not match the SIM card associated with your account' error. Tried for another few hours and never could activate. Tried to call Apple at 800-myiphone and stayed on hold for over an hour with no answer. I called AT&T again and decided I'd go back to my 3G so used a blank SIM I had at the house and had them switch back so I would have a working phone. After they did that they told me my 4S SIM would no longer work and I would have to go to the AT&T store and get another SIM. Went to the AT&T store last night and waited a long time to get a SIM while watching people walk in, buy a phone and walk out with it working,...argh. They were convinced they could get me working so they put a new SIM in my 4S and tried to get it activiated. They got the same error about the SIM card not matching. Then they said the problem was on the Apple iTunes side. Oh...and they told me by the way...switching out my SIM put my to the back of the line...great! They said Apple has to get their servers in sync with AT&T and until that happens I won't be able to get activated. They thought it would start working around 11 or 12 last night...assuming that things would be getting caught up. I tried until about midnight. Then got up and tried from 2am to around 3:30. And tried again this morning at 6:30am with no luck! I've also tried to find an Apple store I could go to today and there are no appointments available....of course. May just switch back to my 3G for a few days and then try again. At least I will have a working phone. Never been so frustrated. I am so disappointed in Apple....I think Steve Jobs must be rolling over in his grave...this is so not the way to roll out a new product!

Palm Centro WiFi SIM card

I've read about WiFi SIM cards, but so far, all I've found are the kind used to make your phone a WiFi hot spot. I don't like cell phones, and I don't plan on using that feature of my Centro, but I do want to access the internet with it. Is there a SIM card replacement that would connect to a public WiFi network?

Turbo Sim Cards

hello
i would like someone to please explain a little about a sim card and its uses with the iphone 3g. does it come with one or is this something that is purchased seperatly. I dont know the purpose of this and if it has anything to do with speed. thank you for all your help in advance. i am new to the forum and dont know if the reply will come back to me but if not my address is [email protected]

The SIM card is merely what GSM phones use to be identified on the cellular network. Some phones are able to store contacts directly to the SIM card so that you can swap it out more easily when you upgrade (the iPhone doesn't).
The iPhone comes with a SIM already inside it.

Dear sir I bought my iPhone 4 from Apple store in Charlotte N/C about 2years ago without contract. Now I tried to upgrade it to iOS 7.0.4.but after that my phone not work with last sim card. And invalid sim appeared.so I bought it without contract but it

Dear sir

Now I tried to upgrade it to iOS 7.0.4.but after that my phone not work with last sim card.
And invalid sim appeared.so I bought it without contract but it seems to be lock in my country
Please tell me whats the matter?
My phone serial no 86034HTCA4T
Modem firmware 04.12.09
Thanks

Without contract is not the same as unlocked. The update to iOS 7 relocked
the iPhone to the wireless carrier to which it was originally locked. You must
contact that wireless carrier to see if they offer unlocking and if you qualify.
If you used jailbreak or other hack to unlock the iPhone initially, the method
used may prevent a legitimate unlock from succeeding and may render your
iPhone unuseable.
