As far as I know there are two possibilities to get this error message.One is poor signal of that respective network for which you just need to switch OFF and ON your mobile and the mobile will be able to receive the signal from near by tower.You may also get this error message when you are trying to insert a sim other than which the mobile is locked to.To solve this problem you need to unlock the phone from that particular network or use the same sim to which the mobile is locked to.To unlock get unlock code from http://www.onlinegsmunlock.com/supported-phones/rs5wp7/

SOURCE: n 72 network prablem

Could be an intermittent provider issue, not sure. You could be selecting somebody else's tower that your provider has banned.

I tend to blame phone's antenna or an amplifier (if it has such). I have had exactly same happened to me two weeks ago with AT&T - "no access" on manual mode, unstable, weak, come-and-go connection. What I did was:
1. removed battery and SIM from the phone and kept it this way for maybe four hours
2. put those back in, did NOT turn the phone on.
3. completely charged the battery, i.e. once indicator says "battery is charged" I would unplug and plug back the AC cord - it will begin another incremental re-charge, at I would keep doing it for at least another hour.
4. turned the phone on - strong connection.
You wanna try this?

Blackberry Curve keep showing SOS network


It means your phone is not receiving signal from the network. First turn off your phone, remove the battery and insert in back in, then you turn on the phone. If it still does not receive signal, then you go to the phones menu, scroll to settings, then you select the network settings, after that select the manual network search, then a list will be searched out, select the network operating network of your Sim. If it still does not see the network, then it means there is an internal problem.
Hope this information helped.

Am trying to use 3 sim and a lebara sim in google nexus one.But its not working at all. i have no idea what's wrong with it.When ever i insert a sim card it is showing a network but not connecting or...



Firstly you need to make sure that the phone is unlocked i.e. it is not tied to another network. Secondly, perform a manual network search. You do this by going into your menu and selecting: (i)settings, (ii) network services, (iii) network selection, then (iv) manual. It will then search for available networks: click on any network first, and then go back into it again and click on Lebara. If that still does not work try the SIM in a different handset.#

No network covrege


Hi, It may be due to the network service provider in that area alone.You try putting ur sim card in other phones and if it shows the same , then sim card is ur prob.change to a new sim with same number from ur service provider.If the above two shows positive then the receiving antennae of ur phone is weak. service ur phone.

When i put my sim card into my blackberry it says invalid sim... what is going on? It's an unlocked phone I purchased on the internet and it is not working... can anyone help me?


Hello,

It looks like the telephone is SIM locked.

If you go to Options > Advanced Options > SIM Card and type MEPD.

This will bring up another screen. If the Network option shows "Disabled" then it is unlocked.

If its locked go back to the seller or buy an unlock code online.

Hope it helped.
