It may take a few minutes before the battery icon appears on the screen.
I cannot use Internet-based services

phone are correct. Contact your network operator for more information about your
subscription settings.
No network coverage
•
Your phone is in Airplane mode. Make sure Airplane mode is turned off.

Your phone is not receiving any network signal, or the received signal is too weak. Contact
your service provider and make sure that the network has coverage where you are.

The SIM card is not working properly. Insert your SIM card in another phone. If this works,
it is probably your phone that is causing the problem. In this case, contact the nearest
Sony Ericsson service center.
Emergency calls only
You are within range of a network, but you are not allowed to use it. However, in an
emergency, some network operators allow you to call the international emergency number
