I have seen other forums and posts around the same thing. (Also seen a few with this issue but regards to WiFi itself)

Brand new S26 ultra connection issues:

No sim card error message

Emergency calls only message

Showing 5g/4g and bars but data not working 

Signal disappearing all together 

No H data when poor signal occurs

Data is inconsistent

I believe remedial lies within Samsung as it is affecting many users, and there have been the usual torubleshooting steps which has not resolved:

New Sim

E-sim

Resetting network 

Factory resets

On/off device

Updates 

Toggle airplane mode

Adjusting other connection settings

Even new device:

What are samsung doing in relation to this, as for a brand new phone to have global issues all on the same things with no fix in place is astonishingly poor.

Some have reported faulty antenna/WiFi chip.

      • EE as provider, and where phone was preordered from and delivered to as an upgrade. But if you have a search there are other forums regarding the same issue with multiple replies of other people experiencing the same things too

      Submit a bag report, that way you will get assistance in an update soon. Inform other to do that as well

      Same issue here done everything like you said and nothing. Lets hope it gets fixed soon, so incredibly fustrating for a £1300+ phone to have these.

      I have connectivity problems on WiFi and on carrier network. Everything is fine for a period of time and then suddenly, the connection becomes real slow and times out. Only a restart of the phone or a flight mode toggle solves the problem until it happens again...

      Really? Why do you think that is? Because other sims show up sometimes but my actual own sim doesn't want to know at all

      Unsure, but have already exhausted a new sim, factory resets, resets of network, airplane mode on/off, I've heard people have tried esims and still have it, new device, adjustments of other settings etc... there are a few other forums about connectivity issues and multiple comments from other people experiencing this too

      So far, the only issue I've had is with the mobile internet. I can have full bars but still not be able to connect. I have noticed one thing which is what leads me to believe that it is a Samsung software issue, which is when this is happening it will take 7-10 seconds to the airplane mode to toggle on, whereas when this isn't an issue, I can toggle on airplane mode in about 1-2 seconds.

      So it's us apparently, we're turning on airplane mode and turning it off, when we're not. And when our screenshots don't even show airplane mode.1775660949602.jpg1775660980576.jpg1775660980596.jpg

      I sent an error log as soon as it happened (they recommend within ten minutes). But they're saying it was me, it wasn't 😂

      Have anyone resolved this issue?  I tried every suggestion but none of it works.  I have been using the S series for more than a decade now and am very disappointed with S26. I shouldn't have upgraded from my s22 which was such a reliable phone.

      Make no difference with or without the software updates. I had the same problem when I first got the phone

      Same here. We need samsung to take us seriously and not just fob us off. Every avenue has been exhausted from customers and nothing. They need to take accountability and put a fix in place. Old devices work fine, it's either the components like someone mentioned the wifi chip, or a bug in the code, either way they need to do something
