SIM card doesn't connect to 5G signal

Hello Community team,

 

I'm a personal Pay Monthly customer on Vodafone's Unlimited Max plan. Last week, I upgraded to the iPhone 12 Pro Max 256Gb phone and have retained the same Unlimited Max plan. This plan has 5G, the phone supports 5G but the SIM card doesn't connect to 5G at all. It simply defaults to 4G all the time even if I manually change the data settings in the phone to always go for the 5G signal if available.

 

Vodafone's network checker shows that I live in a 5G coverage area with good service indoor & outdoors. To ensure that coverage isn't an issue, I purchased a Voxi 5G SIM card that supports 5G to test out. The Voxi SIM connects to 5G the moment you insert it in the phone and the speeds are good (500Mb download & 50Mb upload). 

 

So this means that for some reason the Vodafone network is blocking my Vodafone Pay Monthly SIM card and doesn't let it connect to a 5G signal. Possibly a setting on the network side. 

 

When I discuss this with customer services, they try to get me to swap SIMs but I know this will not fix the problem if the same settings from my account are being transferred from old SIM to a new one. 

 

This issue can only be resolved by making a change on the network side at Vodafone. Has anyone faced this problem and have any suggestions on how I can get Vodafone to fix this problem?

 

Many thanks in advance for all the assistance.

Update - I tweeted to @VodafoneUK a couple of times but they didn't even bother to acknowledge.  So I was left with no choice but to continue calling CS.

 

Notes from approx. 10-15 calls to CS totalling over 4 hours in last few days -

  1. Each time, you have to explain the issue from scratch even though call notes were left on the account. You'll typically be connected either to the Consumer Technical Care team in India or the Converged Care team in Egypt.
  2. Even though I had demonstrated that my plan has 5G, phone is 5G enabled and that I'm in 5G coverage area and even tested this with another Vodafone & Voxi 5G SIM to rule out anything other than the network blocking my SIM to connect to a 5G signal so only recourse is a full SIM disconnected/reconnection, this is a challenge for CS guys to understand and they'll try to blame you, phone, etc.
  3. After I politely insisted, the CS agents tried to create an internal escalation to a "Super User" who would only interact with the CS agent by email with them (perhaps they need to be advised a good telecom company who can provide them with phones to speed up interaction).
  4. Was told a Super User will pick up the case, call me before doing the SIM deactivation / activation.
  5. Nothing happened so next day chased and was told that there is a backlog of 190 cases but this particular CS agent has a friend who is a Super User so will email (again not phone or transfer the line).
  6. Nothing happened again so chased next day, this time I was told a Team Manager can do this deactivation/activation and will be done in 30-45 mins.
  7. Nothing happened so called again later that afternoon (yesterday), I was told notes on account updated and I'm now being transferred to tech team and was on hold for 30 mins before I gave up and disconnected.
  8. A few minutes later they must have triggered the deactivation and so SIM lost all connectivity as expected.... Waited around 45 mins to restart the phone and lo behold, the SIM connected to a 5G signal. 

So, if you have the same problem as mine, please insist on a full SIM disconnection/reconnection (fancy name is de-provision/re-provision) and not get distracted by SIM swaps and other device related settings. 

 

@Mark, @Tash, @Jack, @Stubbo, @TJ - if possible, it'll be great to update the guidance for CS team about how to manage these cases so there can be a quick resolution for the customers.

 

P.S. - After my services were reactivated, I saw in the app that the next month's charges (line rental, usage charges, etc.) will be wrong. As I had done an upgrade on 22 Nov, my previous plan's line rental credit (as they charge in advance) etc was removed when they deactivated/reactivated yesterday. So I'll have to put in more calls when the bill is generated on 5 Dec to explain the history and get them to apply a credit.... Vodafone is the gift that keeps on giving!

I share the frustration with you though.

After reaching out to Apple, it appears that I was using an eSIM as well as a physical SIM on the iphone 12. I have been informed that if you are using an eSIM and a physical SIM on the iphone 12, you will get no 5G signal. I have also been informed that if you only use single SIM, you may not have access to 5G, depending on the iphone 12's firmware as to when it is best to connect to 5G signal. 

 

I know that this is hard to swallow but maybe the link below might offer you some help...

I think most devices that use Qualcomm don't support dual 5g/4g and has been "coming soon" for ages. Apple are more likely to actually deliver though than most Android phones in my opinion. iPhones do warn about it when enabling dual SIM at least.

That is true though. 

It is sad...

Further update... 

Swapped my handset 5g sim with my Vodafone Gigacube 5g sim, handset connected to the 5g network, Vodafone Gigacube with my handset 5g sim only connects to 4g+ so proof that the issue is in fact on Vodafone side.

That is a bummer. 

 

I have tried using the 5G SIM card on the iphone 12 and it does not really register 5G when it is idling. It will only run on 5G occasionally. 

 

When I swapped the same SIM card to a Samsung Galaxy S20+ 5G. It can detect 5G all the time, especially after yesterday's update to One UI 3.0.

connecting to 5G only when it needs to will save your battery!

I do tend to agree with you, however a phone that has 5G capability will have the battery management to cope with connectivity to the 5G network, otherwise not much point right? 

 

When my phone did connect to the 5G network 6 months ago, battery was not an issue, at the end of the day, its a far greater more efficient service, so one would expect operations to be generally better....

That's why iPhones give you the option of 5g auto or on.

 

  • 5G Auto: enables Smart Data mode. When 5G speeds don’t provide a noticeably better experience, your iPhone will switch to LTE automatically, saving battery life.
  • 5G On: always uses 5G network when it’s available. This may reduce battery life.

Well, cant comment as I don't have an iPhone, only Android but take your word for it, General consensus I think is that Vodafone have issues with 5g accounts, some work, some don't, fact is mine did 6 months ago then for some reason my phone stopped connecting to the 5g network. 

 

I know that its on the Vodafone side as I proved my so called 5g handset sim doesn't connect to 5g in my 5g handset or my 5g router, yet 5g router sim connects to 5g network in both. I've raised a ticket and hopefully they will do the right thing and sort it.

I have exactly the same issue, simswap did nothing.

I have tweeted (DM) vodafone UK for further help so will see what they say.
