Getting internet on all my apple devices?

Hi… I have Macbook and Iphone. I'm currently using TATA Photon+ CDMA datacard (no SIM on datacard) on my Macbook for browsing the net. I recently purchased ipad2 (Wi-Fi+3G).

My question: I need to access internet in all my 3 devices @ home and I need to access internet (during non-Wi-Fi spot) on my ipad2 while I'm outside.

Note: I can use my TATA Photon on wireless router to access internet on all my devices @ home but not possible for my ipad2 when I'm Outside as my TATA photon CDMA doesn't have SIM to carry on ipad.
Whether I need to return/Cancel this TATA Photon and purchase GSM SIM enabled data card so that I can use this @ home and on my ipad2 while going out! I have MicroSIM card adapter for inserting into ipad.

Need your valuable suggestions/feedback.

It is not possible to connect internet to all devices

  • YouTube does not work on all apple devices (iPod, iPhone, iPad), how to fix? On iPad it says an error was encountered, on iPod and iPhone, all I see is the dotted circle loading forever. I can watch videos from other sites except YouTube. What is causing this problem? I can watch YouTube from my laptop but not from my itouch, iPad, and iPhone.
  • Will all data share across devices on iPhones with the same Apple ID? My dad recently got an iPhone 4s for his birthday and I currently have an iPhone 6. My iMessages went on to his phone without me putting on any sharing settings. I do not have iCloud or anything like that. I was wondering if any other things will go through on his phone
  • Wi-Fi sync with all three apple devices? I have an iPad 2, iPod 4, and iPhone 4. I want all of them to do Wi-Fi sync with my macbook pro. HOw do I do it? Note: Only the iPod touch seems to work with that, but the other two just won't do it. Does itunes only allow one device to be set up for Wi-Fi sync? Help! I have checked all three to sync through Wi-Fi, but only the iPod works.
  • Why won't my internet connect apple devices? My internet will not connect to any apple device, weather its iPods or iPhones, it doesn't work, although what puzzles me is that it works with my friends Samsung. What should i do?
