Problem with sending sms

[#1]

I upgraded the new software and then the problems started with sending sms? Messages sometimes they go just fine, and sometimes not. Can not determine what it is.

When the SMS messages don't send, what error message do you receive? Does your SIM card work fine in another phone?

Yes, in another phone sim cards work ok. As for the posts, messages are on the phone and after a while we are on the display appears the message has not send. I checked with my friends and have never received such messages. А онда једно време све ради ок.

I noticed that the new software has the ability to set the message center?

You can check the service centre number by dialling the following number:

*#*#4636#*#*

Scroll down to SMSC. This is the service centre number. To check that this is correct, you would need to contact your network operator directly.

Yes, there is a number of my message center, and behind him stands the number "145". What does this mean?

Is it important to set the sms, network Setup: GSM only; WCDMA only and GSM/WCDMA?
