How to disable traffic alert messages which come as flash sms from carrier? I get this alert message (screenshot from my phone) from my carrier after using the internet for sometime. The problem is that I get numerous messages (20+) like this when my phone is idle. I guess some apps are syncing in the background. The phone is unusable till I hit OK on all the alert boxes. Is there a way (or an app) to make sure that I do not see these messages.
This looks like a special kind of SMS message, sometimes called "flash SMS", that shows up instantaneously on the phones screen. I don't think that there is an option to block these messages and even if it would be possible I wouldn't encourage you to do so, because you could maybe miss some other important information.

I think the best approach would be to ask your carrier from disabling these messages for your number. I am sure that they are able and happy to do so.
