Network busy error

S

Phone was working fine on Friday Mar 28.  Sat Mar 29 I could no longer call or receive calls.  Everything else works fine.  internet and texting all normal.  When I try to call out I get no tone or ring and after about a minute I get  “Network busy” and the call cancels.  Very frustrating since the phone is not quite a year old and has worked flawlessly since I got it.   It is a Nokia G22 running android 14.

I have been to my local Koodo and Telus providers and have not gotten any answers as to why this happened.  The phone is in a case and has not been dropped or abused.

It looks like the compatible frequencies used for voice part of your service has been changed. Your phone does use some of the 4G bands that Koodo does, so it should work as well to make calls over VoLTE. I would check with the following site if Telus considers your device VoLTE compatible:

https://www.telus.com/en/support/article/how-to-use-volte?INTCMP=Tcom-support_results-hub_lte-volte_how-to-use-volte

If it is, you may need assistance to get it reenabled. If not, you may have to use the Shizuku app to get VoLTE going.

    Hi ​@ShaunD, here are some troubleshooting steps you can try https://www.koodomobile.com/en/help/im-not-getting-any-network-service

    Is it possible to test your SIM card in a different phone, can you make calls then?

    Is VoLTE enabled and working on your phone?

    I see your phone only has the 3G 850 / 900 / 2100 bands and Koodo uses the 850 and 1900 bands.  If you do not have VoLTE enabled, you might be able to connect to 3G reliably as Koodo is starting to re-purpose some 3G bands to 4G LTE

    Koodo uses the following frequency bands:

    • 4G LTE and LTE Advanced:
      • 2100 MHz downlink and 1700 MHz uplink (AWS)
      • 1900 MHz
      • 700 MHz
      • 850 MHz
    • 3G HSPA:
      • 850 MHz and 1900 MHz (UMTS)
    • 5G:
      • 600 MHz: Band n71    
      • 1.7/2.1 GHz: Band 66
      • 3.5 GHz: Band n78
      • 3.8 GHz: To Be Deployed

    I tried all the recommended.  My sim card works in other phones.

    What I want to know ...is what changed? 

    How does a phone go from working fine for eleven months -- to not doing it’s most basic feature ...being a phone over night?

    I picked this phone because it was user repairable and I could change out a broken screen or a dying battery myself.  [neither has happened by the way -- it’s a great phone]

    It is 4G and it worked.  Now I can text and go online but not make or receive calls.  Who pulled the switch?

    I am a pensioner, I can not blithely change phones every year.

    Thank you.  I’ll look into the Shizuku app.   

    My phone was compatible for 11 months and is the phone registered with my provider.  It would have been nice if they had let me know this was going to happen. 

    Not your fault I know and I thank you for giving me something to look into at least.

    3G and the 1900mhz band is still widely available.  It sounds like only the 850mhz band was impacted.  So if you had a fully Koodo compatible phone it would not have been impacted.  This is likely why no notice was given.  4G and 3G bands change occasionally as towers get changed, updated, moved, etc and there are never notices
