The SIM card must be of the same service. For example, you can't use an AT&T sim card on a T-Mobile phone. If they are the same service, your sim is not made to work with that phone. You will have to get a new sim at your local retailer.

    Thanks I actually figured it out. I took my stepdads sim card and put it in and it worked just fine so I figured mine must be dirty so I cleaned it. Now it works just fine.

What can i do if the phone is saying invalidy sim card


If your Nokia X6 16 GB Displays invalid sim card while inserting other Network GSM sim card like MTN ?
It is locked to network.You need to specify which country and network it is locked now.I have bought an Nokia X6 16GB in INDIA but it was locked to Australia Vodafone network .I have unlocked it and now using it in USA AT&T network sim card.So you can unlock your Nokia X6 16GB from current network lock using the unlock code from the site Onlinegsmunlock.com after unlock it use with MTN network sim card or any GSM pay as you go sim card it will not display invalid sim card message.

Nokia 5800 xpressmusic. i just recived this new phone from a friend because he bought a new phone. i put my sim-card in it it asks me for my simcard code. it accepts the simcard code but than it says...


I'm assuming your both on the same network? If your both tmobile customers or AT&T it should work without problems.

If not. The phone needs to be unlocked. to be used with another sim card from a different company.
And to do that. Your friend can call his carrier he bought the phone from, request an unlock code, then unlock it that way, and you'll be able to use it just fine.

Only if your on either Tmobile or AT&T. No other sim cards will work.

Invalid sim


1. (easyer way) When I got my Blackberry, I had to put it in a couple of times for it to work.

2. Buy a new sim card.
If this does not work, then check to see if it is unlocked.
