No SIM card. HELP!

Everyone here seems to be addressing the memory card issue... which i think is the least of the problem... The sim is not being read, that's the major issue. One way of fixing this is by downloading Titanium Backup Pro and using the clear cache feature. Worked for me. Keep in mind that your phone has to be Rooted.

I HAD THE SAME ISSUE WHEN I TRANSFERED PHONES, AND I FIGURED I DIDN'T NEED TO ADD THE LOCAL OR SAME AREA CODE AS ME FOR IT TO WORK, BUT YOU DO !!

Its a software issue version remember this phones have two softwares android and motoblur, already tried to update the ANDROID?

These directions are for an AT and T phone, but other than that would be the same for any carrier.

A PUK (PIN Unlock Key) code is required to unlock SIM cards that have become locked following three successive incorrect PIN entries. If your SIM card becomes locked, you will need to get a PUK code from your phone carrier to unlock your SIM card.

You can obtain your phone's PUK code from your carrier in one of these ways:

Log in to Your account.online

PUK Codes

A PUK (PIN Unlock Key) code is required to unlock SIM cards that have become locked following three successive incorrect PIN entries. If your SIM card becomes locked, you will need to get a PUK code from AT&T to unlock your SIM card.

Since I don't know the name of you carrier, I'm using AT&T as an example. Most carriers use the same methodology though the wording may be different.

You can obtain your phone's PUK code from AT&T in one of these ways:

Take the phone into your carrier's retail outlet.

OR

• Log in to myAT&T online
• Use our Technical Support Chat.
• Contact Customer Care


To get your phone's PUK code online:

? Log in to myAT&T.
? From the myAT&T tab at the top of the page, hover over the Wireless link and select Phone/Device under the My Wireless Service heading.
? From the My Phone/Device screen, select the Unblock SIM Card link under the My Make & Model heading.
? The Unblock SIM screen will display your PUK code and will give you instructions for unblocking your SIM Card.

Once you receive your PUK code, you will need to enter it into your phone to set a new PIN code.

Note: If you enter the wrong PUK code 10 times in a row, your SIM card will be invalidated, and you will need to purchase a new SIM Card. The phone will display the following error: "PUK blocked call operator."

Second Solution:

You can also do it without any assistance from anyone. However, be sure to read the following carefully because there are pitfalls. If you want to try to do it yourself, just click on the following link: Universal Software Solution for Unlocking a SIM Card

Although most people remember their primary SIM PIN code, those other codes - used for various verification purposes - are never to be found when needed. Below I've included a set of short codes which, when entered on a handset's standby screen, will let you easily change PIN and PUK (short for Pin Unlock Code) codes - but keep in mind, they may not work with all handsets and mobile operators.

More importantly, when changing one's PUK codes there'll be no help to get from the mobile operator if the new codes are forgotten, so make sure to write any changes down alongside the old PUK codes.

The Final Solution:

The following methodology does not work for every phone. Perhaps you'll be lucky. Also, please note that the codes should be entered without the spaces shown below.

Change SIM Card PIN
** 04 * old PIN * new PIN * new PIN #

Change SIM Card PIN 2 (Write down the new code)
** 042 * old PIN * new PIN * new PIN #

Change SIM Card PUK (Write down the new code)
** 05 * old PUK * new PUK * new PUK #

Change SIM Card PUK 2 (Write down the new code)
** 052 * old PUK * new PUK * new PUK #

Display Handset IMEI
*# 06 #

This was wordy but hopefully it helped you.

Your phone is under warranty and so Nokia must give you support for the problem seen. The SIM card detection pins can be dirty or loose and so the contacting could be bad but being a new phone it is not possible. However it is best to remove the SIM card and wipe the contacts with some spirit and a cotton bud and wipe it clean to have a polished surface.
If there is a loose fitting of the SIM then this must be complained.
However as you have observed if the fault is intermitent it can be due to a faulty mother board, possible poor solder joints or tracks that are cracked.
In this case you MUST get a free service or part replaced and so DO NOT TAMPER THE SET until you show it to NOKIA CARE.

Hi john_russo6,

Unless you know the lock code, you will not be able to unlock it.

the phone says you have an " Invalid Sim card " this means your either using another sim card or you entered the wrong code too many times.

the only way to resolve this issue is that you take your mobile phone along with your receipt to a nokia shop dealer and ask them about your issue, they are sure to fix it.

I Hope this helps.

Hi,

I've experienced this problem for countable times. This is not a problem with your tablet pc but a problem with the network on some sim cards (specially if it is old). You just need to wait for it until it allows you to send messages again. If this will happen for more days, I suggest you to buy a new sim card.

Hope this helps.

ur sim card is dead buy a new 1
