Hello my nokia 5230 has a problemes when i put in the sim card i get sim card not valid could you help me please


Hi I'm a mobile phone Tech.

If your mobile phone is on a contract with a service provider, most of the times it will be locked in with them for the duration of the contract,
So if you try to insert a sim card from a different service provider, it may say "sim card not valid'
Try to insert your original sim card and see if that works.

Otherwise if this IS your original sim card and all of a sudden this message "sim card not valid" has appeared, then the sim card has gone faulty and you need to get a new sim card from your service provider eg... Vodafone.

Hope this is helpful

Hi i have nokia 1100 the problem is when i put the sim its say sim is not valid


HI,
ERROR:The sim card is not valid.
SOLUTION:
1.Check the sim card with another mobile.
2.Else,the sim card is not registered(which displays the message "sim is not valid") and we have to call customer care and tell them to register your sim card.

My imate jamin wont read any sim card


Mate...same thing happen to me. I put in 3 different sim cards which all work on my other phone. So, try fiddling with the plated contact on the sim card holder (lack of other term for it). I just raised the contacts a bit, making sure there is good contact between the sim card and the leads. Works fine now. Good luck.

PS

be careful not to raise the pin to high or the pins might snap.

Sim not valid


look at the pin of the sim card connection (yellow coloured) , raise it up (so that it'll be well attached to your sim card when you put it.)

if problem still occur, try strengthened the screws in your phone (learn to open the casing of your phone). might just be the problem of loose parts of the body of your phone (that near your sim card)

if problem still occur, the feet of your sim card connector (that's attached to the machine board) might be broken, bring it to technician to reattached it.

Good luck ^^
