No BIS on 8520



Can anyone please assist.

I have a BB8520 and for the past week, i have no BIS. Which means I cannot access bbm, email. whatsapp, internet, etc. The "egde" remains in small case. I am on Pay as You Go and i have topped up 2 weeks ago. I have no issues with SMS's or Calls. I have contacted my SP and we have troubleshooted every possible thing and nothing works. I also have 4 people in my house, 2 of which have the same model and same SP, and they are NOT having any issues. I tried to insert my SIM into another phone, and it gives me the same issues. I also tried inserting someone else's SIM into my phone, and it has the same issue. At this stage i am so confused and i have no idea what to do. Does it mean my phone and SIM are faulty? Or what could it be?

I restart my phone almost 50 times a day. It works for about 2 minutes after every restart, then its back to no BIS.

I am so frustrated...its been a week and my SP still has no concrete feedback for me.

Can anyone please assist?

Thank you

Re: No BIS on 8520

Hi and Welcome to the Community!

With a strong carrier network signal (e.g., not merely WiFi), 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) Resend Service Books (pre-BB10 devices only)

  • 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) Reboot

  • Pre-BB10 Devices ONLY. 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.
  • BB10 Devices. Hold the top button down until the counter reaches zero. Wait for the device to be fully shut down (e.g., nothing at all displayed on the screen, no LED lights, etc.). Hold the top button until the red LED is lit. Wait through the full boot-up process. IF this fails, you can attempt the battery-pull method above, but it is normally NOT recommended unless nothing else works.
  • 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 contact your mobile service provider for further formal support...consider...you pay them for 100% of your services and 100% of your formal support...right now, they seem to be delivering neither to you. Further, only they can look "behind the scenes" at their systems to discover why this is not working. Only they can formally escalate your case up to BlackBerry for enhanced support if such is needed. But, all in all, this definitely is a problem that your carrier needs to work out...so as to enable those services you pay them for.

Good luck!
