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?

It appears that idata is no longer working for some reason.
Maybe O2 needs to push a carrier profile update to restore it or maybe it's a permanent change but either way we haven't been told anything officially.
Maybe @Chris_K could check for us please?

Yep, checking 🙂

Unless folk have already done it I'd fully recommend going to Settings > General > Reset > Reset network settings. This will wipe all your Wifi passwords so you will need to re-enter any when you reconnect to one that's password protected.

Why the above? It's the magic button of network type issues with the iPhone. It's been known to resolve MMS issues, restore mobile network when returning home from abroad etc etc... It might work for you, it might not work for you but work for others...

Cheers Chris.

Thanks Chris - I forgot to say I had also tried this as well to no avail, only changing APN settings so far is the only workaround that is successful. Let us know what you find out

A bit late for some I know... but I presume we should be advising people on O2 to delay this update till we hear it's 'fixed'?

[MI5]

I did suggest that a few days ago but we're still no nearer to knowing what needs fixing yet ?

Well it would all be gobbledegook to me anyway....but at least if someone asks.. I will know there is a problem that needs resolving....:smileytongue:

Out of interest though...could people roll back from this update?

[MI5]

Prob not now.

Ok...but at least I have learnt something...This time last year I wouldn't have even known to ask this blumming question

Apparently you can still. ......
