Lost 4G after ios9 update

[Anonymous]

Hi

I have an iPhone 5S and last night did the update to ios9.  All went ok, phone worked well on home wifi, thought no more of it.

Went out this morning and realised I had no cellular connectivity.  I could make calls, and send texts, but when I tried to go on Facebook, send/receive emails, go on Safari etc it said I had no connectivity

I thought , "Ah, I know how to rectify this" and texted ACTIVE to 2020 , and received an immediate message back saying "We have had problems with your request for settings, please call us on 4445" .  So I did this, and the lady said she'd done something their end, I should restart my phone and all would be fine.

I did this and yes, I now have connectivity.  But only 3G.  Not 4G.  I called again to be told they have been having problems with the mast in my area of late , and coverage will come and go.  Now, I've always had 4G in this area, it was working fine yesterday, and now it's not.  I don't believe it's the mast.  I think it's something to do with the ios update changing settings.

Any ideas of what I can do please?

Sorry but visual voicemail will not work with an APN of mobile.o2.co.uk.....you need idata bolt on and idata.o2.co.uk if contract or payandgo.o2.co.uk if P&G.

In my case, the root looks like missing bolt on specific for iPhone, even tho I have had many an iPhone for ages and not had any problems previously (even changing tariffs) until ios9 update came along.
Re: the APN details, those were the ones given to me by a "Guru" over the phone - no-one's perfect.

My (missing) bolt on goes live tonight so we shall see if all is well tomorrow.

Thank you very much. 

I had the same problem - those settings fixed it.

I'm on iPhone 5 (so it'll never be 4G), but the 3G had broken after my update to IOS 9 yesterday.

And the Visual Voicemail does seem to work too now.

------

"Settings > Mobile Data > Mobile Data Network

Mobile APN = mobile.o2.co.uk (was idata)

Visual Voicemail = mobile.o2.co.uk

MMS = WAP.o2.co.uk

u/n and password stay the same (vertigo/******)

No worries

Changing the idata settings to mobile fixed mobile data for me - it wasn't working at all though I've also just changed to sim only contract from a refresh one.

Yet to see if it's fixed 4G as I live in a 3G area but will see when I go to work tomorrow.

If you are having to use mobile.o2.co.uk it means you don't have the iData bolt on provisioned on your account.

It should be as been using my 5s for months now - unless it's lost that provisioning when changing my contract to sim only? I tried texting 2020 but got back an error message, resetting network settings didn't work either.

I'll see tomorrow if I have 4G on my journey to work and let you all know how it goes.

hi there. i had same problem after ios 9 update, no data working at all. took my iphone 5s into o2 shop today and the guy changed Mobile APN = mobile.o2.co.uk (was idata) now all working and can confirm 4g to be working aswell

[Sammy_boy]

I got a new sim this morning after swapping to a sim only contract - tried that (after doing the sim swap) - still no data working using the idata settings - it would show 3G and a signal but apps would just say there was no internet connection. Sending active to 2020 on this sim again returned an error text from O2.
However, after changing the APN to mobile from idata as suggested above, data is again working - including 4G so far.
