Hi @tuckyjr211


Ok let's see if we can help before you use your phone as a skipping stone ! 


Firstly I've updated my Note 9 to the Samsung One Ui  / Pie and its not affected my phone this way so if you've also updated to Samsung One Ui I doubt it's the update.

To be fair no official update should cause this.


So a few things to try are and ask are> 


Sorry to ask this but can I assume your Bill's are paid and up to date.

Also did Vodafone supply the Samsung Galaxy s8 phone ? If not is their a chance the phone has been imei blocked by the original owner ?

A site called checkmend can show you if its blocked.

If its imei blocked then only the original owner who has asked for it to be blocked can have the bar lifted. 

If not blocked.....

Another thing to try is Manually choose another network in your phones connection settings and then choose Vodafone again.


Try a soft reboot by turning the phone Off and On or alternatively you need to hold the power button and the volume-down button for roughly 7 seconds. Then let go of the buttons once you feel the device vibrate and see the Samsung Galaxy S8 logoon the screen. Your phone will then reboot, and then hopefully start working properly.


Does this happen everywhere or in one area ?

If one area check your postcode in the Vodafone Status-checker and look at the Network-issues-initial-checks-and-template.

If it's happening everywhere then to rule out the phone or sim card then please if you can as a process of elimination insert your sim card in another phone and see if you get a signal. 


Try another sim card in your phone.


Check in your myvodafone for any bars.

Customer service on 191 or Live Chat can check your account from their end.


Regarding the phone itself put it into Safe Mode which disables your downloaded apps and leaves the stock ones working which can help you to determine if this is a rogue app causing this.

Safe mode is accomplished by the instructions in Samsung > how-do-i-put-my-samsung-galaxy-s8-into-safe-mode

A Samsung Experience Store or Samsung Service Centre can run a diagnostic test on the phone for you too.

I understand there's alot to try and quite a few links but I hope you get this resolved asap. 

Please let us know how you get on.

Current Phone > Samsung Note 9 _512Gb > Model: SM-N960 Hybrid-Duos.

@tuckyjr211 Thanks for taking a look at @BandOfBrothers post and getting back to us 😊
We'll need you to try your SIM in an alternative phone, to determine where the error may be occurring (whether the problem is with the SIM, phone or network). I understand you don't have a spare phone to try yourself, so if you can pop into your nearest Vodafone store, our advisers there will be more than happy to test this for you. 
Please pop back to us on here once you've tried this and let us know how you got on.

In the meantime, I'll be happy to check the network in your area and see if there's any current issues. 
So I can do this, please try the steps in our network troubleshooting thread.
If you're still experiencing the issue after completing these steps, post the template with your answers in this thread.

Thats all for replying

I had a look online and there was no problems in my area, I have had my SIM for like 4 years so it could be on its way out

I managed to borrow my mates phone and I left it alone for like 30mins and I had full bars, so I think my phone is on its way out

@tuckyjr211 Thanks for getting back to us. I'm pleased to hear you've tried your SIM in a different phone and doing this has improved your signal/coverage. As this is the outcome, this would suggest the underlining issue is with the phone you're currently using. I'd recommend visiting your nearest Vodafone store, so that one of our technical specialists can examine your device and see if there's an issue which is repairable
