If your phone displays the 'Insert correct simcard' then your phone is currently locked to particular network. You need to unlock to use it with other network.
There can be many ways to Unlock your phone. As far as i know unlocking by codes is the simple and safe way. I will suggest the website Unlock-zone.com which is doing good service and they were recommended highly in the cell phone forums.
I used them to unlock my cell phone. contacted them and within 30 mins i had my unlock code and my phone was unlocked.
Hope this helps.

Just bought a Nokia Fold 2720 - unlocked. Inserted SIM Card and get message when Texting "Sim Card not ready"


Hello,

Once you insert a sim card inside the phone. Be patient with it, allow it read the sim card, and settle its software. If you try to send a message when you just insert the sim into a phone, the message you will be getting is 'sim card not ready'.

Please insert the sim back into your phone and wait for about 3 minutes before trying to send a text. That way the sim card would have been ready to perform your operation for you.

Thank you for using fixya

Hi i have a samsung SCH-W339 mobile the problem is i have inserted many sim cards but it displays limited service instead of displaying the sim name and i cant make outgoing calls neither i recieve...


1. Your sim card is not in the right position. Take out your battery and your sim card. Make sure it is in the right position. Also make sure no dust or dirt where the sim card goes. Put the sim card back in your phone and battery. Turn it on. See if the insert sim card goes away.

2. If it goes not, then you will need a new sim card. Go to your local service provider store to get a new one.

It comes up with Insert SIM Emergency? What is SIM?


A SIM card or Subscriber Identity Module is a portable memory chip used in some models of cellular telephones. The SIM card makes it easy to switch to a new phone by simply sliding the SIM out of the old phone and into the new one. The SIM holds personal identity information, cell phone number, phone book, text messages and other data. It can be thought of as a mini hard disk that automatically activates the phone into which it is inserted.

A SIM card can come in very handy. For example, let's say your phone runs out of battery power at a friend's house. Assuming you both have SIM-based phones, you can remove the SIM card from your phone and slide it into your friend's phone to make your call. Your carrier processes the call as if it were made from your phone, so it won't count against your friend's minutes.

If you upgrade your phone there's no hassle involved. The SIM card is all you need. Just slide it into the new phone and you're good to go. You can even keep multiple phones for different purposes. An inexpensive phone in the glove compartment, for example, for emergency use, one phone for work and another for home. Just slide your SIM card into whatever phone you wish to use.

High-end cell phones can be very attractive and somewhat pricey. If you invest in an expensive phone you might want to keep it awhile. Using a SIM card, it is even possible to switch carriers and continue to use the same phone. The new carrier will simply issue you their own SIM card. The phone must be unlocked, however, and operate on the new carrier's frequency or band.


When it's not inserted properly, it displays insert .You will need to insert the sim card properly so that the message won't come up again..

My proble is i insert sim in mobile massage show please insert sim. my mobile model is m200 samsung


Hi, when a phone displays an insert sim message, it means that either the Sim card or the Sim tray where the sim card is inserted in the phone.

First, You can use the sim card on another phone to be sure that the sim card is still working properly. If the sim works with another phone, that means the sim tray where the sim card is being insert into the phone is bad and will need to be replaced.

You `can contact a skill personnel for help.

Have a nice day.

Samsung e-250 i need unlock code


Please follow the instructions carefully! Following are the 12-point instructions to unlock your Samsung E250 phone:
1. First do a CUSTOM RESET by tying in:
*2767*2878#
(Phone may display foreign language – don't worry! The last digits after the * will appear as - - - -; this is normal)
2. Turn off your phone
3. Take the battery and SIM out of the phone
4. Take a wrong network SIM (a SIM the phone does not currently accept) and insert it ONLY HALF way in, so when you turn on the phone it won't detect the SIM. Very important so the phone won't ask for network password and will show "Insert SIM" message.
The process of inserting only half of the SIM. I advice you to take care and do it with a soft approach as you might not have done this before.

5. 2. Now put the battery in carfully behind the protruding SIM card and switch the phone on. The phone must show "Insert SIM" message.
6. 3. Without turning off the phone, now push the SIM card all the way in, at this stage the phone must continue to display the "Insert SIM" message with the WRONG SIM inside.
7. Now make a FULL RESET by typing: *2767*3855#

9. Change the NCK password to 8 zeros by typing: *7465625*638*00000000*00000000#
8. The phone should reboot working with "wrong" SIM inside. (Do not turn off the phone)
10. Disable network lock by typing: #7465625*638*00000000#
12. Check this is done with *#7465625#
If your phone is not unlocked please retry the above ensuring all steps are followed to the letter, 9 out of 10 people who have problems have made a simple error and find that when they repeat all the steps it works.
