Network issue Samsung galaxy S25 ultra

[sohelsaad]

I’m facing a network issue with my Samsung Galaxy S25 Ultra. I live on the second floor (in London, using a Three SIM), and while my other phones show full network coverage, the S25 Ultra has a very weak signal. Often, it’s difficult to make calls. Is anyone else experiencing the same problem?

Ahoy there!

I have the same issue in my newly purchased S25. RSRP and RSRQ values are noticeably lower on the new device while on my older A72 are higher in the same cell. Both phones are registered under VodafoneGR network and sim is tested in another phone as well with no issues and stronger signal levels. Measurements performed under the same 4G cell in my area

From India here. Facing a weird Network issue. So my network goes away in basement parking but its normal, happens with other phones too. But when i come back in open, the network doesnt connect unless i restart my phone or turn on and turn off the flight mode. PS: This is happening with the esim

Yes I'm having the same problem in Australia. I had an s22 which had full bars in places I go regularly and now I only get one bar where ever i am. I do have the sim that was in the S22, so I'll try getting a new sim and see how it goes.

I came in here to check this as well. I got on the same walk most mornings and both times I've been on my S25 Ultra it's cut out...and my Note 20 Ultra never had the issues on the same walk.  Can newer SIMs potentially fix this?

This issue exists with S25. It seems like there is an issue with radio firmware. I have eSIM and having major issues on SIM 2 always showing "Emergency calls only". Horrible device.

Pathetic device. Should have stuck with my 16PM.

Trouble here too. Weak signal fairly regular. Currently 2 bars of signal right now.

I have 2 esims. Both on different operators. Since I changed my phone from Ultra s24 to Ultra s25, my signal is awful. Missing calls at home. S24 ultra, same rains, same networks were flying... how Samsung going to sort that issue out? Feels like I wasted £1350. Very disappointed 😞
