On my Nokia mobile phone, the SMS sent by the system was not completely received, resulting in "text loss". How can I make it right? urgent

1. Delete useless messages if you can. Lost words have a lot to do with the storage of short messages. 2. Don't worry if you see "Lost Text" displayed on your mobile phone. Delete the previous message, not the received message. Then exit the standby interface. 10 seconds later, the SMS will be updated automatically. If you don't delete the previous message, after the SMS is automatically updated, "lost text" will still be displayed. I can't figure out why 3. Users who often display "lost messages" without changing the phone to save short messages, it is best to change to SEEM, so that the phenomenon of "lost messages" will be less. 4. If the text received after automatic update is still "lost" or updated separately, there is no way out. Let the MM who sent you the message resend it, or let her send it one by one. Generally speaking, 95% of messages with more than two pages received according to the method I mentioned above will not display "lost text". Try to delete useless messages anyway.
