iPhone 17 Pro Max - Signal Strength

[Baldie1977]

I purchased the iPhone 17 Pro Max on Friday.  The signal has been fine but I went to work today for first time today since owning this phone and I now get barely any signal.  My iPhone 14 Pro was fine in this location I had 2 bars and all apps requiring data worked.  My iPhone 17 Pro Max has 1 bar and I get told I have no internet connection.  Is anyone else having this issue.

I have done all the normal things deleting Nord VPN, resetting network settings etc etc.  Nothing works.

The on-screen bars should be treated as a basic guide and not anything more definitive.

If multiple phones in the same location have similar problems using voice or data, it points at a network issue - use "check service status" on https://ee.co.uk/help/mobile-coverage-checker in the first instance.

If another EE phone in the same location is working fine, try a 2way SIM-swap. Put the working SIM in the non-working phone - what result? Put the non-working SIM in the working phone - what result? Then you'll know where to look next.

Firstly I’m using an eSIM and it was my old iPhone 14pro that worked fine on Thursday I swapped to new iPhone 17 pro max on Friday and it now I’m struggling to get any reception.

The lack of ability to fault-find in scenarios such as this, is a clear disadvantage of eSIM.

You're limited to checking other phones in this location.

Everybodies work phone at this location is on EE and is working fine.

Which clearly rules out a network fault.

The on-screen bars shouldn't be, of themselves, an issue - you'd need to go into the hidden engineering menu on iOS and compare the radio levels between a "working" phone and "non-working" phone to make further judgement.

The phone not working for mobile data is another issue. Does it work elsewhere?

Same problem (iPhone 17 pro) little to no coverage on data compared to previous 16 pro on same network. General signal isn’t as good. Gone from 5g in my house to 4g. No issues on other phones in the house and no details of signal problems in the area.

Same questions as above then!

What do you mean by "little to no coverage on data"? On-screen bars are a rough guide, nothing more. Voice calls & data use the exact same network signal.

Are you describing slower data speeds? Inability to use mobile data when coverage is shown? Or something else?

[ip213]

Inability to use mobile data when coverage is shown. Just constant buffering. Never had a problem before..

Thanks for the extra info @ip213 

Does this also happen when away from home? If other phones aren't affected it could be the device itself in which case everywhere would be affected.
