For most of the phone,sim card will be install at the back of your mobile phone. These are the steps on how to: 1. Turn off your mobile phone. 2. Remove the back case gently. 3. Remove the battery as well. 4. Theres instruction at the back of your phone on where to place the simcard and on how to insert it. 5. Make sure you properly inserted the sim card so you wont recieve offline mode error. 6. Plug back the battery. 7. Return the back cover. 8. Turn on your phone,then your good to go. remember that there are some phones wherein the simcard slot is on the side part of the phone. for this kind of phones,all you have to do is just lift the cover of the simcard slot then slowly insert the sim properly then turn on the phone and your good to go.

Hello,

Try removing the simcard and the battery. Then replace both and check if the problem is fixed. If not, remove the simcard, replace back the battery then do a master reset. Press menu then scroll to Advanced, Connectivity, Master reset, Reset Defaults > Reset Settings or Reset Defaults. If it still won't work, try using a different simcard. Your simcard might be defective.

Hello.

You need to have a simcard. If you already have one inserted, then remove the simcard from your mobile phone, then reinsert it back. It is usually found behind the battery. If you are still having the same error, then you might need to change your simcard.

try removing the simcard from the iphone by inserting the end of a paperclip into the small hole at the top of the i-phone, this will push out the simcard. Then clean the simcard and re-insert it into the phone, the issue should now be resolved. if it persists then it could be because you have a faulty simcard in which case take your i-phone to your nearest apple/o2 store and they should give you a replacement.
