"NO simcard inserted" when sim card is in Samsung Galaxy Tab 2

I bought my Samsung Galaxy Tab 2 7.0 8G 3G wifi about 2 months ago. I have been using the telstra simcard out of my internet USB stick in the tablet and it has been working fine. About 2 weeks the tablet starting saying that no simcard was inserted when I still had the sim inside the tab. I tried rebooting and reseting but nothing worked. The simcard still worked inside my USB stick. I took the simcard to telstra and they replaced the sim. It worked perfectly fine for about a week and now is doing the same thing. What could be the problem?? Is it the tablet? Any one else have this problem? thankyou in advance

How i can put simcard show vedeo


1) you state the problem is with an Apple iPad 32gb Wifi Tablet. You will be unable to put a sim card in as this is not the 3G / 4G version.

2) Refer to the original product documentation.

3) Have you searched the manufacture website? There are online user guides on apple.com.

4) Use a small needle and press it in to the hole on the sim card slot. remove, insert your simcard and insert in to the ipad.

To many patten attempts


  1. With the Samsung Galaxy TAB turned off, press and hold the VOLUME Down button, and then briefly press the POWER button.
Note: If you see "Downloading" on the screen with an Android shoveling you pressed the wrong Volume key. Remove and reinsert the battery and try again.

You may have run out of memory on the system. I would suggest getting a SD Card, then go to your settings and you can click on each of your apps and transfer the ones you want to the SD Card, taking up less space on the Device memory.

How can i move my apps to my ext sdcard on my Samsung galaxy tab 2 10.1


Why do you want to move your apps ? If the card becomes corrupted, or you remove it, you have lost access to your apps. Would it not be better to move your data to the SD card ?

the galaxy tab will be locked to the provider you got it from, which is why your sim isnt being recognised. You will need to unlock the tab to allow it to accept any sim. To get it unlocked you need to request an unlock code from Telstra

Cannot connect samsung Galaxy tab to internet


Your question is very messy. I don't understand what are you trying to say.

Connecting to Internet need WiFi (your home wifi through your router, cafe wifi hotspot, etc) or GPRS (data connect through your carrier/SIM, like 3G, 2G, HSDPA, Edge).

For WiFi, normally you'll need a security key.

For GPRS, you'll need some settings from your carrier.
