Is your iPhone 5 locked with any particular network and you are trying to use it with someother network?If so, you need to unlock the phone to swap networks.To unlock an iPhone the remote unlock service would be a better option because, you need not give your mobile to someone else nor do you have any chance to enter the wrong unlock codes. To get such an unlocking service for your iPhone approach and by submitting the country and network to which the mobile is locked to you will be able to remove the restriction from the respective network. This will be a permanent unlocking solution.They offer unlocking solutions for various types of GSM networks.

Saulcr you may have to do a manual network selection. Go to phone settings, network settings, prefered network, and keep searching and trying each network in the area until it works. Be forewarned that roaming charges may apply.

SOURCE: iPhone SIM Failure

The phone is locked to Apple and needs a Security code to unlock it.
When you place a new or a existing SIM card from another phone provider into your mobile phone and it asks for a Security code then :-
This phone is locked to the original mobile phone provider. You need to contact this mobile provider to ask for the unlock code (security code) for this phone. You need to provide proof of ownership etc and the phone's unique IMEI number which is located inside the phone under the battery. They use this number to generate the unlock code for your phone.
They should provide you with instructions on how to enter this code into the phone.
Once you unlock the phone, then you can insert a new SIM card in this phone or sign up with another phone provider using this phone.

You could ring the phone provider and ask for the unlock security code because you are going overseas and wish to use your phone with a prepaid SIM card from another country.
The other way to get your phone unlock is to use a phone unlocking company on the Internet, they usually charge a couple of Dollars for their services. Use Google and search for “Security unlocking code”.

Why does my phone show invalid sim and where do u put a sim card the back of the phone doesnt come off

Depends on the phone. Most phones, the back slides off or pries off and it is under the battery. iPhones have a little door in the right hand side, you push a straightened paper clip in and it pops open..

How to repair an Iphone 4 front and back screens

You just broke the screen on your iPhone 4. Your expensive phone is now a useless lump of circuitry and you don\'t have the money to replace it or to have it professionally repaired. That\'s quite a predicament. Though a lot of risk is involved, this repair can be done at home. Of course, this should only be attempted as a last resort as any warranty you may have had will certainly be voided. If you\'re brave enough to give this a shot, you can get the replacement parts online.

Turn off your iPhone and use the SIM removal tool to pop your SIM card out of the right side of your device. This tool can be purchased online. Remove the two small Phillips head screws from the bottom of the phone to free the back panel. Slide the back panel toward the top of the phone and pull it straight up and off. Set the back panel aside. Use the screwdriver to remove the screw that holds the battery connector to the iPhone motherboard. Pop the connector up and remove the battery by pulling on the clear tab on the left side of the phone. Remove the black shield on the top of the phone by removing the five screws that hold it in place. Be aware that two tabs on the shield work like hinges. You will need to pull the top up first and then slide the tabs out on the bottom. Remove the small black shield from the left side of the battery compartment by removing the two screws that hold it in place. The small shield will pop right off revealing a connector on the motherboard. Use the plastic prying tool to pop the connector loose. Remove the small vibrator from the top right corner of the iPhone. Remove the two screws that secure it to the circuit board and pull the device out. Unplug the five circuit board connectors from the top of the iPhone using your prying tool. The three smaller connectors must be pulled up from the top, while the two larger connectors on the left must be pulled up from the bottom. Remove the iPhone\'s camera assembly by unseating the connector from the mainboard and pulling the device out. Pull the ribbon cable on the right side of the phone up as far as it will go. This will reveal a screw that secures the speakers in place. Remove this screw as well as the screw at the left of the speaking housing. Carefully pull the speaker assembly up to reveal a wire connector on the motherboard. Unplug this connector and set the speaker assembly aside. Remove the screw on the right side of the phone next to the black moisture sensor as well as the screw holding the circuit board in place near the top of the phone. Pull the motherboard out of the phone and set it aside. Remove the 10 screws that secure the iPhone screen to the case. Three are on the side panels and one in each corner. Pry the screen out from the front of the device using your prying tool. Replace with your new screen and reverse these instructions to reassemble your iPhone. Hope this helps.

How to insert sim card

On top of your iphone you can see a slot for your sim with a small hole at the left hand side of it (screen facing you). With your iphone you get a small metal key, very thin, looks like it came of a sardine tin! Insert the pin into the hole mentioned and the slot should pull out. This could work with a pin or paperclip. Put sim in slot and reinsert.

Hope this all helps and please vote if it does.
