I am wanting to buy and Ipad.. but I would like to know the difference between having wifi and a simcard..if someone could explain this to me.. and the benefits of both I would appreciate it.

Good Morning:
I have been looking at the Ipads for a while now.  I have some concerns though.  First, I am NOT a techy of any kind!!  So my question is;  What is the difference between wifi and a simcard(?)   What I understand about wifi is...if you are in an area with free internet.. you can excess it.  If not, then you can't.  What is a simcard?  Is this what you would use like a turbo stick..such as internet on the go... or is this a data plan for the Ipad, like I have for my phone?  If so, I take it that it would mean a monthly bill of what or however I set it up...  Please be kind with your responces.. I am a older person who wants a new gadget.   
Thank you

Hi, Sarah,
You don't really compare a SIM card directly with WiFi. What a SIM card indicates is that a device is designed to connect to cellphone service, in the case of an iPad a data-only service for connection to the Internet. The SIM card works with a technology called GSM (don't worry about what that means); the SIM card is just how the iPad is identified to the cell carrier (in the US, that would be AT&T).
Your choices of connecting an iPad to the Internet are therefore:
WiFi - wireless network connection which uses a device referred to as a "hotspot" or "access point" (and sometimes a "wireless router") with an Internet service provided by some other company. You may have this at home, with your own WiFi router and Internet service, or it may be found by some other location, such as a coffee shop. Cost of WiFi at home would only be the cost of the router and the fee you pay to your Internet provider. Other locations may or many not involve a cost. The advantage of a WiFi connection is speed (compared to a cellular data service) and cost (no monthly fee other than your Internet provider).  The disadvantage is that you have to be in range of a WiFi service; that range is usually on the order of 100 feet or so.
Cellular - this is a service provide by a cellphone carrier. This allows you to have your iPad connected to the Internet wherever the carrier offers service, which may be in buildings, parks, while driving, etc. just as with a cellphone. You pay a monthly fee to the cell carrier for this service. The advange is of course that it's available in many places. The primary disadvantages are the monthly cost and slower speed in the connection to the Internet.
You can have both with an iPad if you purchase your iPad with both systems included; iPads are sold WiFi-only or WiFi+3G ("3G" refers to being capable of connecting to a cell network) You are not obligated to sign up with a cell carrier if you buy the iPad with that technology; most carriers allow you to sign up month-by-month, and in some countries the carrier has a pay-as-you-go service. If you tell us what country you're in, someone can tell you more about the available cell plans, if you're interested.
I hope this helps. Feel free to post back if you need further clarification or have additional questions.
Regards.

  • Hi All! I have an iphone 4s. I want to buy an ipad but torn between wifi or wifi cellular. Can I use for sure, my iphone 4s as the wireless hotspot for my ipad if I get the ipad wifi only? And if yes, is the signal/connection good? Thank you.

    Hi all! I have an iphone 4s. I want to buy an ipad but I'm torn between wifi or wifi+cellular because of the price difference. Can I really use my iphone 4s as the wireless hotspot for my ipad? If yes, is the signal good and fast? Thank you for your response.

    Yes you can if:
    1: Your cellular provider offers a data tethering option.
    2: You have subscribed to this option.
    Speed will be as it is with your existing iPhone.

    At this point you have the option of keeping a device optimized version (lower resolution version) of your photo on your phone while iCloud stores a full resolution version.  Or keeping the full resolution version on both your phone and the iCloud. If you delete the photo on your phone it will be deleted on the iCloud. I know, bummer. Also it should be noted that the photos app and the library are still in beta and to this point i see why.  I would use dropbox or a smiliar app for off device storage.
    So far this is how it has been working/not working for me.  Whether or not I choose to keep originals or optimized on my phone it will only keep the originals and it has only been uploading lower resolution versions of my photos to the iCloud library.  Seems to be working in reverse.
    Again these are still in beta so i am hopeful that this will be fixed in the near future.
    I hope this helps.

    Hi I would like to know, how do I add a Hyperlink on Flash, that opens a PDF in adobe reader and not the web browser.

    Yoh, what is FSCCommanr ? sorry man I am an absolute beginner in Flash. I tried the code:
    /* Click to Go to Web Page
    Clicking on the specified symbol instance loads the URL in a new browser window.
    Instructions:
    1. Replace http://www.adobe.com with the desired URL address.
       Keep the quotation marks ("").
    instance_name_here.addEventListener(MouseEvent.CLICK, fl_ClickToGoToWebPage);
    function fl_ClickToGoToWebPage(event:MouseEvent):void {
      navigateToURL(new URLRequest("http://www.adobe.com"), "_blank");
    this is the same code I used before and it opens a pdf file in a web browser, and it doesn't open an AutoCAD file.

  • HT5260 Hi, my name is Gerard and my iphoto library is getting very large I would like to know if I can store all or most of my photos in a external hard drive and access them from Aperture?

    Hi, my name is Gerard and my iphoto library is getting very large I would like to know if I can store all or most of my photos in a external hard drive and access them from Aperture?

    Moving the iPhoto library is safe and simple - quit iPhoto and drag the iPhoto library intact as a single entity to the external drive - depress the option key and launch iPhoto using the "select library" option to point to the new location on the external drive - fully test it and then trash the old library on the internal drive (test one more time prior to emptying the trash)
    And be sure that the External drive is formatted Mac OS extended (journaled) (iPhoto does not work with drives with other formats) and that it is always available prior to launching iPhoto
    And backup soon and often - having your iPhoto library on an external drive is not a backup and if you are using Time Machine you need to check and be sure that TM is backing up your external drive

  • What exactly it the difference between iTunes Wifi-Sync and iCloud Backup?

    Okay, i do not yet have a mac, only an iPod touch, but am (hopefully) buying a mac soon (MacBook Pro to be specific). I buy all my music etc on my iPod, and am currently use iCloud sync which i have all the buttons in the ON position. Anyway, i am rather confused after reading alot about the two methods of syncing there exact differences. When i get my mac can i use both- for reasurance or do i have to choose one? Also, does iTunes wifi sync my photos and videos (thats photos ive taken and videos ive made/filmed) and does iCloud do this. Also if i use both photostream and iCloud/iTunes for my photos, will that create double ups of all my photos?
    Thanks

    Wi-Fi sync works in the same way as syncing over a USB cable, albeit more slowly, and can be used when your iTunes library can see your device on your local network.
    iOS: Syncing with iTunes
    iCloud backup saves the settings and documents from your apps to the cloud instead of your own computer. It seems you either backup to your computer or to iCloud, but not both, at least not on a regular basis. You may still be able to trigger a local backup manually when using iCloud for backup.
    iCloud: Backup and restore overview
    Photostream operates independently of either of the previous features to move your pictures to your computer and other iOS devices when in range of any working Wi-Fi connection.

  • I would like to know why i have to pay a service fee even if my IPOD 4 gen is within the warranty period

    My Ipod touch screen get White there fore i brought it to the premium retailer where i bought it. after 15 days with no anwser of the retailer, i moved to the shop to have more information. they told me that my ipod could not be repaire and i had to pay a service fee even if it was on warrenty. why should i pay for something on warrenty and for something that could not be repair.

    Apple never repairs your iPod, they replace it with a refurbished one at no charge if the product fails on its own.  But the warranty only covers manufacturing defects, if your white screen was caused by abuse such as dropping it or getting it wet, the warranty does not apply.   If that is not the case call them at 1-800-APL-CARE (if in the US) and discuss it with them.

  • I´m from Brazil and I would like to know if I can use the Labview and other National technologies to create a building/home automation (energy, water, lightning,...)? Which would be a ideal project? Which equipments should I use?

    I would like to know all about National technology regarding building/home automation?

    I could help you better if you had an idea of the equipment you will be controlling or reading to/from. Are you planning to totally customize a system or are you looking to use instruments/controllers already available for Home Automation? Im not sure I understand what you really need. Here's an Idea. Computer is the controller of the system.
    System consist of Light Control Only (to keep it simple). Program written in LabVIEW. Here you can create schedules to turn lights on/off/dim. Then LV could communicate, (for example using X10 or other protocol), commands to the device actually controlling the lights. Lighting device could be controlled using some sort of communications like, X10, Serial, IR, RF, Ethernet, etc... So this system can turn lights
    on/off/dim% either at the click of a button on your screen or a timer. Adding any other system in the house will more than likely require a different communication protocol and complicates things even further. You could much of this with regular automation hardware from NI but this requires integrating different components like relays, dimmers, etc.. Much more work and more expensive, (I would think), than buying a device made specifically for the system.
    I hope this helps.

  • Would you please summarize what the difference between tc and alv?

    hi, experts,
      would you please summarize what the difference between table control and alv base on the function and usage practice.
    for example, as i know:
    1.edit
      tc: can edit in the same screen and save.
      alv: pop up a sub screen to let user edit, so this is unconvenient.
    2.functional button
      alv: can have many functional button as default ,eg. sort, summary and so on
      tc:  developers must implements by himself.
    3.color
      alv: can have and change color
      tc:  cann't changed color
    some client may required the data displayed in alv and edit in tc ,such as example BCALV_EDIT_02.
    above are my idea, experts, would you give me some comments on my opinion and summarize what the difference between those two components? i should make it clear in order to consult the UI with my client.hunger for your advice, thanks!

    ALV Grid is basically used for display puropse. It is more user friendly. There are arious features ( such as coloring, sorting, saving to a local file, sedning by mail etc. ) These featurs make ALV Grid a very good option to display the data .
    However , the table control is not only used to display data take from the database table, but also you can do operation such as deletion of data from database table, insertion of data into the database table and updation also. Yeah it has not got the various features whihc ALV has.
    So table control and ALV Grid , if you are just using for display purpose, then ALV Grid is a better option due to its layout and attractive features. But if you want to do the database operations other than display, table control can be used.
    As far as execution is concerned, I think ALV Grid is faster.
    ALV grid control is faster when compared to Table control. But the comaprision is Negligible .
    One of the major differences comes in taking of line items - ALV has an advantage over Table Control when it comes to update database from it.Table control only allows maximum of 999 records at a time where as this limitation is not there in ALV.
    Also,a main feature of ALV Grid is that it contains a standard set of functions. These functions extend beyond the functions of a table control.
    These two UI elements require different keyboard navigation, with ALV Grid being more user-friendly.
    An application can display table data in ALV Grid or in a table control. In some applications you can choose between displaying and editing data in either ALV Grid or a table control. If a configurable button () appears in the right upper corner of the table, it is a table control.
    Basically ALV is a way to display the output and Table Control is designed in screen painter through which you can get entries in Table Control, can delete some records etc for further processing and its not use only for Display.
    ALV is Application List viewer:-
    Sap provides a set of ALV (ABAP LIST VIEWER) function modules which can be put into use to embellish the output of a report. This set of ALV functions is used to enhance the readability and functionality of any report output. Cases arise in sap when the output of a report contains columns extending more than 255 characters in length.
    In such cases, this set of ALV functions can help choose selected columns and arrange the different columns from a report output and also save different variants for report display. This is a very efficient tool for dynamically sorting and arranging the columns from a report output.
    TABLE CONTROL:-
    ABAP offers two mechanisms for displaying and using table data in a screen. These mechanisms are table controls and step loops. Table controls and step loops are types of screen tables you can add to a screen in the Screen Painter.

    This is a user to user help forum only.
    This cannot be determined by users with the info provided, and I'm not sure if Apple would give you this info over the phone if you called AppleCare in the U.S. - for security and privacy reasons.
    You need to get this info from the seller. If the seller is unable to give you this info or the correct info, return it to the seller for payment credit and purchase an iPhone in your country from an official retailer and you will have less problems or no problems including not having to hack the iPhone to unlock it which removes all the built-in security making it insecure as with an Android phone.

  • Hello, I would like to know how to add or delete single cell in numbers.

    Hello, I would like to know how to add or delete single cell in numbers.

    If by delete you really mean clear the contents of a cell, then just click once on the cell and hit the 'delete' button.
    Before:
    After hitting delete button:
    In some circumstances you can actually delete one cell.
    For example here, I make this choice:
    Resulting in this:
    So it's not strictly true that Numbers does not delete one cell, ever.  It can if you have a one-column table. 
    So never say never or not ever! Enough pedantry for today!

  • I would like to know the IP's that have accessed my account?

    Hi Community
    I would like to know if any other IPs (Times & Locations too) my Account of me.com or icloud.com for the FindMyIPhone has been Accessed.
    Like Account Activity you can find in Gmail for Security Purposes.
    Any Users Know how or have a way of finding this out would be grately appreciated as I have been unable to find this information.
    Please dont post back about taking precautions THIS IS NOT what I am after finding out.
    Thanks

    $1000 (actually $999.99) in American Money.
    You would get $700 dollars per app.
    If you want something closer to $200, you can market it for $200 (actually $199.99) and get $140 per app.
    If you want to make around $200 per app, market it for $300 and get $210 per app.
    There are slightly different prices, and you get a slightly different fraction of profits when paid in different currencies.
    You said you plan to sell expensive items. That's in-app purchasing and I believe it would have the same price/revenue choices for you.
    You only decide the price when you are actually submitting the app to the app store (and you can change it later without approval, even if the app hasn't been released yet).
