Is it a new handset? If so it will be locked into the network it was intended for, and if you are trying to use your old sim from another network/operator in this new phone, it will not work until you get the phone unlocked.

If you are saying the sim that came with the phone is saying "invalid", then you need to speak to the mobile provider about this.

If you have used the phone successfuly before & this has just started happenning, the only thing I can suggest is to take out the card, make sure the metal contacts on the card & inside the phone are clean, replace it & try again. If still no joy you may have been disconnected by your network.

It seems your SIM is not fit properly in phone. Otherwise your SIM card is broken. Please double check those things.

New mobile but says emergency calls only etc sim.W890i

Sim fine?
But is this handset able to use your sim?
You say the phone is brand new so where did you get it?
Most new phones have software on them that only allows them to be used with ONE network.
So is this handset on your network or has it been "Unlocked" so that it can be used on any network?

To simplify:
If your handset was purchased from a mobile phone shop they would have told you which network it is on eg T mobile.
This means that if your Sim you wish to use in this handset is 02 it will not work in your shiny new handset. All it will allow you to do is "Emergency Calls"
Or maybe it was purchased from somewhere like ebay and NOT from a reputable trader.
This could mean that the phone has in fact been stolen and the owner has registered it as stolen to their network.
If this is the case the handset would be BLOCKED from accessing ANY network so again would give you the "Emergency Calls" only option.
If you are sure that your phone is brand new and legal you can always have it "Unlocked" so that your sim card WILL work in it.
Phone repair shops or phone unlockers will be able to "Unlock" this for you for a small fee.

Maybe not the information you really want to see but I have to tell you all possible reasons. SORRY!!!

A message pops up saying: Invalid or missing sim card. You can still make emergency calls if your service provider supposrts it. I have a sim card in their but i guess it doesn't read it?? HELP ME PL

Is this phone from the same service provider as your simcard? If not, not all phones are unlocked to work with the sim cards of rival companies. If both the phone and sim card are from the sam company, then you can have the company replace your sim card. They usually do this for free as a courtesy as long as you explain the problem to them. Hope this helps

Phone topped up but can only receive or send

Have you tried different sim to see if its sim or phone related? Try your sim in different phone, is it ok? Where did your K800i come from, have you just got it? Could be restricted from networks if it was a reported lost or stolen phone? (would show as emergency calls only, or unregistered sim). Check with your network provider who have access to imei data base and can tell you if its a barred handset.
Also check if phone is in flight mode as then it would not find any network? Normally allows you to select when turned off and on again.
Does it pick up any networks? If you go into settings, then networks, does it find any when you do a manual scan of networks available?
Last explanation could be faulty handset? ;( = ££££££'s

Emergency calls only

hello sir,
this emergency calls only is seen only when ur SIM is not activated or ur cell phone dosent catches the signal. Well it shows the signal full but thats the FAKE signal.
If ur SIM is activated try the MOBILE NETWORKS in the SETTINGS option  >  Connectivity
U will search for new networks and u will find ur NETWORK Operator

If ur SIM is invalid u wil continue receving the same message  "emergency calls only"
