Hi and Welcome to the Community!!

I suggest the following steps, in order, even if they seem redundant to what you have already tried (steps 1 and 2 each should result in a message coming to your BB...please wait for that before proceeding to the next step):

1) Register HRT

• KB00510 How to register a BlackBerry smartphone with the wireless network
• Please wait for one "registration" message to arrive to your Messages app

2) Delete and Resend Service Books

• KB05000Delete the service book for the BlackBerry Internet Service email account from the BlackBerry smartphone
• If you have no CMIME entry, then skip the deletion
• KB02830 Send the service books for the BlackBerry Internet Service
• Please wait for "Activation" Messages, one per already configured email account, to arrive in your Messages. If you have no already configured email accounts, please wait 1 hour.

3) Batt Pull Reboot

• Anytime random strange behavior or sluggishness creeps in, the first thing to do is a battery pop reboot. With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes. See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure.

Hopefully that will get things going again for you! If not, then you should try deleting and re-adding your BIS configuration for the affected email accounts. Otherwise, you should contact your mobile service provider for formal support.

Good luck!
