CDMA and GSM or GSM only

Hello..

I have iphone 4S (A1387) and it does not work with cdma sim,

one of my friends has iphone 4s, when he his level of force phone sim card ejection keep see the signal.

but mine say (no SIM)

so is mine CDMA & GSM or GSM only?

There is really no such thing as a "CDMA SIM". Some WCDMA carriers use something as a SIM card. To the best of my knowledge, no iPhone support WCDMA.

It seems that if your phone is GSM so it gives you this error message. Your friend uses a CDMA carrier, but a GSM SIM in his phone for international roaming.

  • CDMA and GSM capacity.

    If I buy an iPhone 6, Plus 6 or, say, the Verizon service that is CDMA, can eventually move to a GSM network on the same phone. In other words are fully compatible with both systems and phones not dedicated to one used at the time of purchase.

    Yes and no.

    A little explanation:

    While all iPhones since the 4S have included both CDMA and GSM equipment, allowing them to be used on any GSM or CDMA based, medium

    It's a regular carriers CDMA to activate not only sold iPhones not specifically for them on their networks.

    So if you were to buy say an iPhone AT & T, Sprint and Verizon would have in the past not activate on their service at all.

    Recently the new legislation therefore makes will now Verizon activate iPhone 6s and more 6s on their networks, even if it is not sold especially for them.

    Not sure if Sprint did this also.

    Another issue to consider when buying an iPhone for a specific carrier or in a specific carrier store, the iPhone is locked to that carrier and requires unlocking if you want to be able to use it with other GSM providers.  (CDMA is not unlock, and a based Verizon iPhone never can be used with the service of Sprint CDMA and vice versa).

    Unlock may never be authorized by the carrier in which the iPhone is locked.  So an AT & T locked iPhone can only be unlocked by AT & T.

    In the United States the only source of unlocked iPhones is Apple themselves. If you buy an iPhone at home at full price, it will be unlocked and can be used with any carrier mobile PHONE of your choice.

    Buy an iPhone at a reduced price with a 2-year contract with a particular carrier means that the iPhone will be locked to that carrier, and only that carrier can unlock for use with other providers.

    IPhones unlocked, either from Apple or those properly unlocked by the carrier to which they have been locked in, will never lock to another carrier.

    If you buy a Verizon iPhone at full price with Apple, it will be unlocked and can be used with any GSM carrier. If you buy at a discount with a 2 year contract from Verizon or Apple, it can be locked to Verizon, and you will need the requirements of Verizon to unlock.

  • With the help of Excel, the zero in front of the fixed phone and GSM disappears after moving to the next cell

    Make a list of phone numbers in excel. The zero in front of the fixed phone and GSM disappears after moving to the next cell. Any advice? Worked before excel on request, so the knowledge base only. Thank you. L. H.

    In addition to advice of GTS - NJ, who will work, you can put an apostrophe before the zero and it will cause zero to keep.   Instead of enter 0123, enter "0123.

  • Hi, I dropped my iphone6 in a salt water pool and was overwhelmed for only 3 to 5 seconds. I quickly ran upstairs to put it in rice and it was 2 days ago. Should I start charging or always keep rice?

    Take your iPhone at the Apple Store as soon as possible. Unfortunately, warranty does not cover water damage. I'm afraid that your device is already damaged, but only professional can tell you this for sure. Take the sooner you it to the store - the best chance, it can be recovered.

  • Windows 7 X 64 and now firefox update only works in SafeMode (all off also addons)

    I just updated Firefox with Windows 7 X 64 update kb2670838 number and now I just make me sent to Mozilla error report screen if I'm not in safe mode. I've disabled all my addons and themes. The only way it works (and I might post it) was to use safe mode. I don't not know the difference between safe mode and normal mode. I've updated this after noticing somethings were activated and my theme is enabled but I have disabled since their. I also use the 7 15 java update that seems to work.

  • Windows Picture and Fax Viewer seen only by Crescent and descending file name. I want to do more...

    Hello.  I use Windows XP service pack 3

    When I reformatted the computer earlier (before I updated my service packs and all), I could go in my windows Explorer, I could see all my photos by file name, updated and the date of creation (both increasing and decreasing) with windows fax and picture viewer.

    Now (after installing the latest service packs), when I find my pictures with Windows Explorer, I can sort the photos by what I mentioned above, but windows fax and picture viewer will only see in photos by file name (ascending or descending order), it will not display the photos in order by size, date of creation or update.  Even if the order has changed viewably on explore, I can't see the pictures created or modified or size of the order (order asc & desc).

    I clicked on the update column, with the arrow going down on the selected column, and also once again, if the arrow is pointing upward.  Then I went to double click on the first picture in the amended order, and after I saw the first picture, I clicked on WP & F viewer (or use the arrow keys on my keyboard) the arrow to view the next photo in the changed order and the next picture that appears is in order of file name!

    Now, I want to be able to switch between the use of all columns or sorting:

    ~ file name (order asc & desc)

    as well as

    ~ modification/creation date (also in order asc & desc)

    or

    Size (order asc & desc)

    is there a way to fix this without having to download new programs to view my photos?  Or having to rename one of the file names?

    I don't think that it has nothing to do with the dates of my photos.  They have all of the appropriate dates stamped on.  And rename one of them to a single specific command won't help.

    I really enjoy using windows greatly fax and photo viewer.  I don't want to replace it.  I just want to see my photos in order, I want to see them with windows fax and picture viewer.  And I would be very happy to help on fixing this problem.

    I thank you for your time, and hope you're answers coming soon.

    I restored my computer twice, and I don't know when it started to happen to me, but today I started thinking, ' it did not use to jump around like that. " I am looking for an answer now.

    Edit: Hey, I think I've found a fix for this problem!

    First of all, I tried this http://www.windowskb.com/Uwe/Forum.aspx/windowsxp/162211/Picture-and-Fax-Viewer-displays-images-out-of-ordersite, but the solution did not work for me. Then I found this site http://www.compu-help.us/157.htm, and the first suggestion seems to have solved the problem. My images now show in the order. (Summary: a patch for the computer messed up Windows and Fax Viewer.) To correct, click Start and then run. In the run box, type: regsvr32 shimgvw.dll)

    How do I take a VISTA system which has a drive with a C and D partition and combne in C only a partition with the storage of which was C and D?

    Hello

    Make sure that D: is not the partition recovery including the manufacturer put there to make the recovery disks from and eventually to return your computer to how you bought

    You cannot combine C: and D: and their data using the Vista Disk Manager

    with Vista, you will need to save the data on D: - D: delete - and then extend C: into the now unallocated space where D: was to do a 1 partition 2

    I am running windows vista on a computer hp Pavilion dv6500 laptop.  I had a problems of memory processor very high for months.  I did all the usual, uninstalling programs, etc and I noticed there are some programs norton on my page of uninstallers but no information after them and no way to uninstall them.  Norton Internet Security in figure 5 times, Norton Protection Center, SymNet, AppCore, ccCommon, Norton Confidential Web Protection, Norton Confidential component browser and MSRedist.  As I said, there is not any information thereon.  There are two other programs, Zune Language Pack (FR) 356 KB and Microsoft Office Proof (French) 2007 and they either uninstall when you click it.

    I went to services and found symantic programs. They seem that they have taken and the performance of my computer.

    There's more... So of course, I stopped all these services and rebooted.  I had to go into safe mode, restore did not work and I remember not even how I got my computer to work again.  It took hours.

    I got a list of services and settings of Microsoft and went through all the new and reset to recommended.   When I rebooted, there was a bright yellow screen, my computer took a few minutes to start and it worked... but not internet access.  Only local services.

    I run norton security tool and found this error message in my documents listed under ccErrDspLog

    It is listed over and over again, and it's been long that I ran this program.   I also tried the norton removal tool and which does not work either.
    So I restored again and now my computer works but still the high memory and cpu usage.

    I'll be back on my 486 days and at the command prompt.  I typed
    Config.sys type C:\
    and the only thing listed is FILES = 40

    then I typed C:\ type autoexec.bat and it's the only entrance...
    ..

    I know that this is not normal... Anyone know what it is?  I would just reinstall, a great fight, but not to big, but I want to know what it is and where it comes from?   Thanks for any advice.

    First of all, autoexec.bat is not used in Vista. Try to use the Norton removal tool to get rid of all Symantec programs.

    I cannot perform certain functions because he says that I'm not an administrator, but it's my computer and I'm the only person who uses this computer

    What are the functions? More global changes (changes to the system, software installation) require an elevation in Vista/Windows 7.

    Changes to the built-in Vista administrator account

    http://support.Microsoft.com/default.aspx?kbid=942956

    User - recommended configuration (Vista and Win7) accounts

    You absolutely don't want to have only one user account. As XP and all other Windows 7, Vista, and modern operating systems are operating systems multi-user with integrated system of accounts as default Administrator and comments. These accounts should be left alone because they are part of the structure of the operating system.

    In particular, you do not want account only one user with administrator privileges on Vista and Windows 7 because the administrator account integrated (normally only used in emergencies) is disabled by default. If you use as an administrator for your daily work, and this account is corrupt, things will be difficult. It is not impossible to activate the built-in administrator to rescue things, but it may require more work you want to do. Better not to get into a bad situation at first.

    The user account that is for your daily work must be a Standard user, with the extra administrative user (call it something like 'CompAdmin' or 'Tech' or similar) only it for elevation purposes. As a user Standard is recommended for security reasons and will help protect your computer against infections. After you have created "CompAdmin", connect to it and change your normal user account Standard. Then log on to your regular account.

    If you want to go directly to the desktop and ignore the Welcome screen with the icons of the user accounts, you can do this:

    Start Orb > Search box > type: netplwiz [Enter]
    Click continue (or provide an administrator password) when you are prompted by UAC

    Uncheck "users must enter a user name and password to use this computer". Select a user account to connect automatically by clicking on the account you want to highlight and press OK. Enter the password for this user account (when it exists) when you are prompted. Leave blank if there is no password (null). MS - MVP - Elephant Boy computers - don't panic!
