I am very new to Kudoos. About two hours ago I updated my plan. When I tries to make a phone call I get this message. "Not registered on nerwork,"

Can someone please help me out.

Thank you

Hi ​@NewfieMudder, please note you have a physical SIM card associated with your Koodo number. We’d advise testing the SIM card in a different phone as the A53 phone showing on the account is flagged. This is likely why you’re not getting service. Please let us know if the SIM works in a different phone.

I suggest restarting your phone.

Did your line work previously before changing your plan?

Did you sign up with a plan, then change your plan right away in your koodo self serve account?

 

Are you signing up to Koodo new or moving from another service?

Yes the lines worked before I made the change. Yes I started my plan a week ago and and made a change through self serve...

Do you see the esim active on your phone manager?

When you login to your koodo self serve do you see your line or multiple lines?

Did you restart your phone?

In koodo when you try to change your esim does it show the esim number Match the one in your phone's sim manager or is it different?

Have you tried resetting your network settings in the device? This can help clear up connections to the Koodo network. If you’re unsure how to do this, then if you can let us know the device model we can walk you through it. This tends to help with most things. If that does not work, then deleting and re-downloading your eSIM from Koodo self-serve should do the trick.

What Dennis is suggesting is checking if the eSIM ICCID profile from Koodo is assigned to your device or if they don’t match. If they don’t, then you won’t be able to use your Koodo plan. However, this can be hard to find on Koodo self serve as they don’t openly display it. When going through process to replace your eSIM normally it will display this, but now it just walks you through downloading a new eSIM. This wasn’t the case before but seems to have changed.

I suggest resetting the network settings and see where we are from there.

I was talking to a rep last night he walked me through this as well. I was put on hold and he never came back. After over an hour he called back put ne on hold again and never came back.  Its terrible I started as a Kudoos Coustomer Aug 27 and I still can't get any service...

I see, I can understand your frustration. In that case let’s try and get you sorted through here. Did you end up finishing the process without the rep? If not let us know your type of device (iPhone / Samsung etc) and we can walk you through resetting the network settings and see if that helps.

Thank you my friend

No the Rep didnt fix things, he put me on hold and never came back.

When i try to make a call I gets a message "not registered on network" also up in the top right corner it's says unregistered SIM.

My phone is a Samsung Galaxy A53 5G.

ok, in that case let’s go ahead and reset your network settings to see if this does the trick. This is assuming that in your eSIM manager, your Koodo eSIM is still showing there as you described before.

To reset your network settings on a samsung device, do the following:

Go to your device settings → scroll down and select General Management → Scroll down and select Reset → Specifically Select “Reset Network Settings” → then you will be prompted to select a final “Reset Settings”.

Once done, it will say your network settings have been reset. If your device does not connect to the network after a good 5 minutes or so, try restarting the device a couple of times to refresh your connection to the network. Note this will also reset your Wi-Fi and Bluetooth settings so you will have to reconnect these as well later. Let me know how it works out.

To confirm, did it say that your network settings had been reset? and can you share a screenshot of this “phone is locked message” in case it has more details.

The message popped up and disappeared right away. Not quite sure if it said network settings have been reset.  Gonna try again.

ok, that sounds better than the previous attempt, hopefully that did the trick. As I said before, if you don’t connect to the network after a good couple of minutes after the reset, try restarting the device a few times. If this does not work, then the next step is to delete the existing eSIM profile on the device and get a free replacement through Koodo self-serve.

Sounds like you'll need to delete the existing Sim and replace it. If that's still not working, we can continue in options
