Hi 

 

 

 

Hoping to get this in front of Jason Paris. @jasonparis

 

This is not a beat up, Our business acc has been with Vodafone for approx 15years, and apart from these issues lately I have no complaints. 

 

 

 

There have been several threads on Alexandra local FB pages about frequent loss of connectivity, 

 

Phones receiving not signal and displaying a no carrier message, Txt messages not being delivered till phones are restarted.

 

This happens at random and can require restarting phones several times a day

 

 

 

I noticed this with our business phones approx 8 weeks ago, 

 

and there are about a dozen complaints on a recent message for people and business within Alexandra and surrounding areas being affected by the same issues

 

 

 

Quotes from different FB contributors. 

 

 

 

1. We have 3 different android phones and have same issues poor to no service have learnt to go to airplane mode then back so don't have to restart phone . Have emailed and rung vodafone and they tell me that there is no issues with the network in alex . It is worse in buildings . But have 4g and full service in Naseby while working there but little to no service in Ranfurly. Think will have to take everything to Spark .

 

2. Similar issues with our business cells says no service turn them off an restart an they reconnect to the network missing a lot if calls vodafone fired a heap if their nz tech staff and outsourced to india recently

 

3. I'm sick of it too! Have changed to Spark this week.Was only getting emergency calling only at 1 stage

 

4. My phone has it seems to have no service then i reboot it and it comes back its very frustrating as i miss business calls that are important to me

 

5. I’ve been on Vodafone 20 years and always used to say the coverage was awesome never had a problem but the last 6 months + the coverage around Alex has been terrible. More often than not on 3G and not 4 and the signal is weak especially on the outskirts of town. It’s been driving me nuts.

 

6. Yay, not just me

 

7. Have been having issues with this for about 8 weeks. Intermittently looses service and have to restart phone to get it going again. We contacted Vodafone two days ago and their response was: we’ve checked our outages in Alex and there don’t appear to have been any.

 

8. I have this almost every day and sometimes more than once (no network) very frustrating

 

9. have been both having those issues too, it’s a message like “please contact your carrier”.

 

10. Is anyone else getting zero cell phone coverage from Vodafone in Alexandra this morning?

 

 

 

Can Vodafone get a Network engineer or equivalent to investigate these issues, advise if there is a problem and a likely timeframe to resolve? .  

 

 

 

Its obvious in the thread locals have not had a positive experience logging faults regarding these issues. 

 

 

 

Thanks

 

 

 

Jeremy

Two guys from Vodafone are now chasing this.

 

One has been in contact today.

Have to wonder if this is in some way related to the Dense Air 5G deployment being used by Spark. This 2500/600MHz deployment is already causing issues in other parts of the country where WISPs using gear in the 2500MHz band are being affected by this 5G signal.

 

In the 5G NR world nearby networks don't play happy with other nearby networks unless they're 3GPP compatible and have frame sync enabled.

 

The only problem with this theory is that I'm not sure how it could affect Vodafone as they're not going to be operating on that band, unless they're somehow being subjected to massive noise ingress into their network and not filtering this out. The timing of this issue however seems to be way too coincidental.

Here is a link to the NZ Herald about Spark 5G in Alexandra, Central Otago

Thanks Steve & Linux,

 

 

 

The 2 Network Engineers from Vodafone that have been in contact.  Have taken this seriously. 

 

Alexandra has been signal mapped by Vodafone's drive team. 

 

If there is interference it will be picked up. 

 

In my case loss of signal was causing my phone to connect to the strongest available signal which on occasion was spark.

 

The spark network was holding on to my phone leaving me in no man's land for 6hrs till the phone would force a renegotiation.

 

Manually selecting Vodafone as the network operator has helped those of us that were observing that fault.  

 

 

 

I hope Spark have not been the cause of this issue as Vf has lost a chunk of customers that couldn't get resolution thought the helpdesk and changed carriers.

How many remember just before the Telecom XT launch and it ended up in the high court

 

https://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=10570881

 

The result is that Telecom says will fast-track the installation of network filters on its transmitters, which will work towards resolve the interference issues Vodafone claimed its customers were suffering

The issues created by the Spark / Dense Air 5G network are slightly different to the XT issues.

 

In the areas Spark are causing issues there is nothing to suggest they are actually breaking any of their licence requirements. Co-existance of 3GPP and non 3GPP based solutions in the same band is a potential nightmare without sync between the networks, and while I'm not aware of VF using 2600 down there it's entirely possible that VF are suffering issues because of noise ingress if they're not filtering the band.

 

If this was the case it's not necessarily Spark / Dense Air at fault per se, but things do become a little complex if another operator has to implement filtering or network changes because of a new build by another party.

This is quite interesting. I also live in Alexandra and in the last few weeks my wife's phone has been doing something very similar. She is on 2 degrees and multiple times it has lost all cellular connection untill it has been rebooted. I just put it down to her tech incompetence but sounds very similar to this issue. I am on 2D as well but haven't had this issue. She has a Huawei 3E, I am Samsung Galaxy S9. So could be handset related?

On android goto "settings" then "connections" then "mobile networks" and select "mobile operators" and choose "select manually", your phone will disconnect and scan then choose 2Degrees,

That does not mean the handset will stay connected to the network

You are just forcing the handset to reattach and 6 hours later good chance it will drop off the network again
