N95 on offline mode, not coming in general or other mode, when any sim card inserted ' sim card not valid'

hi malik, you're still having the same problem though, now you know that your phone has the error..
try these steps on your N95 phone.
1. on your keypad, press *#7370# for soft reset
2. then, insert your sim back, check if your sim has been recognized, if it doesn't do step 3,
3. on your keypad, press *#7780# for hard reset once finished, insert your sim back and switch on. if the phone still doesn't recognized the sim, then do step 4.
4. on your keypad press *, 3, call key and power switch at the same time, to make a hard formatting on your phone and setting it back to its factory setting.
>> under above steps, you need to make sure that, battery is fully charge, if not, fully charge battery before doing all the steps above. don't forget to remove your sim every time you do the steps (so as the sd card if your phone has it).
>>>please make a note that, if all of the above steps has failed,or nothing happened and still you have the same issue, then go now to a phone repair shop and have them check your phone, it can be a hardware problem. if your phone is still under warranty, try not to do the steps above, instead, go back to that phone store and return your phone and show them your problem, so they can immediately replace it.
>>>also, make sure that your phone is network unlock and can be use with other network sim.

good luck.

MY samsung jet (no network

try to do these steps:
1. switch off your phone, remove battery, sim and memory card.
2. reinsert your battery and switch on your phone.
3. on your keypad menu type this code to make a hard reset. *2767*3855#
4. after hard reset, reinsert your sim, battery and memory card and check.

you may also want to try these.
1. remove your sim and have it check with other phone if it's receiving a signal.
2. insert another sim to your phone and check if it will receive a signal .
3. check your phone profile settings, press menu, select settings, select phone profile, select normal mode and check if it will give you a signal.

if you found out that your sim has defect, you may buy new sim and replace it, but if your phone has the problem after all of the above steps, go to your nearest samsung service center and have it check. if it's still under warranty, you may want to consider returning it your phone dealer, where you bought it, and have it replace with new one.

good luck and take care...

Blackberry pearl- initialization problem

I had the same problem and find the answer on other forum I used some scotch tape and worked perfect for me, the idea is to make the sim card a litle "fat" to fit the contacts.

Good luck

Here is your solution: 
Now follow these steps to a "T" don't do any shortcuts etc, this is "across the board" for all sidekicks it worked on my Sidekick Slide and on my Sidekick 2008.

1. Remove battery and the SIM card from the devise.
2. Flip the sidekick open; press and hold the letter "r" on the keypad
3. While holding the letter "r", place the battery back in the device. DO NOT INSERT SIM CARD YET.
4. The Sidekick will restart itself twice. Please make sure not to let the letter "r" go until it has fully rebooted.
5. Once it has fully rebooted, remove the battery, reinstall the SIM card and battery.
6. Power up device.
7. Once the device has fully rebooted, all prior information should be erased from the device and it should be restored back to the default factory setting.

Still not working!!

I would take the phone into your provider and see if there something going on with the keypad.

I believe the cover and the buttons can be removed. That way you can check the key contacts for obstructions.

No response from keypad input?

check your volume keys or any side keys that get stuck... or if you can open your fone check its keypad for any shortage...

Can only receive calls and turn the phone on and off! cannot dial out, access my contacts, ect., keypad not working at all.

If you are comfortable taking part of the phone apart there is something you can try. Remove the two Torx screws right below the battery. Gently pull the plastic cover loose. There will be a cable that connects this portion of the phone to the keypad/LCD/etc. Clean the connector on this cable and the connector it was plugged into with 99.5% Isopropyl alcohol. Reseat the cable and the part of the phone you removed and replace the screws you removed. If this does not work the keypad flex on the phone is probably damaged and will need to be looked at by a repair center.
