Vodafone UK warns its iPhone 4S users not to upgrade to iOS 6.1 due to possible 3G problems

Vodafone UK warning its iPhone 4S users not to upgrade to iOS 6.1 due to 3G problemsUK network Vodafone is warning users of iPhone 4S handsets on its network to avoid upgrading to iOS 6.1. Vodafone is sending out text messages to its users as well as issuing a statement that claims Apple is already working on a fix for the problem. Apparently it is only affecting iPhone 4S users and is an intermittent 3G problem causing failed calls and texts as well as internet access problems.

We’re aware of an issue caused by Apple iPhone 4s handsets that have been upgraded to iOS 6.1 which impacts performance on 3G.

Some customers may occasionally experience difficulty in connecting to the network to make or receive calls or texts or to connect to the Internet. Apple is working on a solution to their software issue. These connection problems are intermittent.

While Apple’s investigations continue, we would recommend that anyone who has not yet installed iOS 6.1 on their iPhone 4s should delay doing so until Apple has confirmed that their problem has been fixed.

We know that Apple has already released iOS 6.1.1 beta to developers for testing and maybe this contains the fix that Vodafone is referring to. As with any new release of iOS firmware there are always many differing reports especially when it comes to battery performance. This release has been no different in that respect however the fact that Vodafone felt the need to publicly comment on this particular 3G problem does mean it could well be a major problem for many on its network.

My wife actually has an iPhone 4S on the Vodafone network in the UK and it is updated to iOS 6.1. Her iPhone is working perfectly with no sign of any issues with 3G. If there are any other readers on Vodafone in the UK experiencing any issues, please let us know in the comments!

Vodafone UK warns its iPhone 4S users not to upgrade to iOS 6.1 due to possible 3G problems


This post comes as a complete shock as I thought that I was the only one to be experiencing such a problem. I am suffering severe issues with the Internet access on my iPhone 4S and as a result vodafone issued me with a new SIM card to try, this didn't work and therefore presumed it was my handset. Despite being in contact with vodafone via email not one member of staff has made me aware of an issue with iOS 6.1

What is strange is that when I connect my ipad to my iphone via hotspot the Internet works perfectly, it's only on the phone that I lose the ability to connect to the Internet or it runs extremely slow.

Here is the last reply I received from vodafone yesterday:

Hi Stephen,

Thanks for your reply.

Since you're still experiencing slowness in browsing internet with a replacement SIM, it seems it's the device causing the issue.

We can't confirm it until the handset is checked. Since you're unable to use the SIM in another handset device, can you visit any Vodafone store so that they can identify the issue? If it's found to be faulty, it will need to go through the repairs route.

I appreciate your patience in the meantime.

Many thanks.

Yeah, had the same issue with my 4s last year, when on the O2 network. The issue was on all version of iOS though. After multiple replacement SIM cards etc, an a 24 month period of poor customer service, I finally jumped ship to 3 network.

I've not had a problem since. We live in a blame society, where a mobile service provider will be quick off the mark to blame you and your device, rather than their own systems.

Vodafone have confirmed the story via twitter, I don't understand why I have been fobbed off with a replacement sim etc when they obviously knew there was an issue :-(

I have also experienced significant call and Internet access problems since upgrading to IOS 6.1 last week and I have a 3S iphone with Vodafone carrier . The fault is clearly not just related to the 4S

Having same problem with iphone 5. Data is intermittent.
I thought it was my carrier and they even replace my simcard.
I now know is apple's fault, hope they release a fix soon
