Same identical issue I am in Chicagoland area. I just yesterday got a Verizon SIM card so now I have 2 accounts one T-Mobile and one Verizon with identical issues. Funny part is that when i am moving such as driving on the highway internet connection is perfect but as soon as I'm stationary I lose it all. For my phone March 6th, issue didnt start till March 24th. T-Mobile blaming Samsung, Samsung blaming T-Mobile and now Verizon blaming unlocked phone.
Any fixes suggested to network issues about Sprint issues did not help on T-Mobile and Verizon, including bands. I have attempted all troubleshooting steps including Factory Reset.
This is Samsung's issue that should be solved with software not refurbished phones with the warranty especially considering people have replaced their phones and have same issue.
I have called UBREAKIFIX and they told me that in past 48 hours they had 6 people come in with same issues. 2 were using unlocked version and 4 were using T-Mobile version, and that they can't do anything and recommend replacing the phone but that doesn't appear to resolve the issue. It is just an extra step to waste our time since no one wants to address this issue.
Went to UBreakIFix. They re-flashed the current software (ASBA), said they didn't have anything newer. Waste of time, no difference. I called samsung and reviewed all of the steps I've taken. They wanted me to send it in to Samsung, who would send it to the official repair shop, which is 10 miles away from me. I told them 5-6 days without a phone wouldn't work. My phone only works reliably at home with my sprint magic box and wifi. He said they can't push updates, carriers do that, even for unlocked phones. This is my first unlocked and i thought that was sammy's job with unlocked. Anyway, they agreed to send me an exchange. I have to wait for case management to call me to confirm, ~24 hours. They send me a brand new phone, i'll send back this one. I still believe it's a software issue and would love to have an update pushed to not waste any more time. They can't confirm the new one will have any different software. I'll keep my fingers crossed that the new one works.
Another S10+ user here with serious cellular connectivity issues on T-Mobile. Figured I'd chime in just to help futher expose how widespread this issue is and how many loyal Samsung fans are becoming exceedingly frustrated with this issue. This is no longer a "mobile" phone. This is very serious. I have spoken with T-Mobile and with Samsung. Samsung acknowledged the larger issue and indicated they are working closely with T-Mobile. Hopefully, that will speed the deployment of a patch if root cause is ever discovered (assuming software can fix it). I lost patience and requested a warranty replacement. While I'm expecting the new phone to encounter the same issues, the hope is that there will be a short span of time during which the phone works normally; buying some time for Samsung to deploy a fix. It's really a shame. I do really like the S10+ and Samsung in general, but they are putting us S10+ owners in a very difficult position...tempting us to switch to another manufacturer (something that is very easy to do with T-Mobile jump-on-demand) when we'd really rather just have a working S10+.
I'm having the same issues as everyone...new S10 +, Sprint carrier, no mobile network outside of WiFi. Tried Sprint's tech support options with no change. Did the software update last week with no change. Took the phone back to the store (only had it for 6 days) & they replaced it, hoping it was just the phone. STILL NO SERVICE. It'll show full bars with LTE and still have no connection. I asked the store what I should do if I still have network problems...they said to contact Samsung. Really??!! Someone needs to figure this out. Quick. For now, the Better Business Bureau website might be my next stop!!!
I have the US factory unlocked s10+. I am using it on sprint and I have the same issues as everyone here. Spoke to both Samsung and Sprint reps but they barely speak English and are totally incompetent as usual. Thinking about switching to Verizon does anyone know if people are experiencing the same issues?
From what I've seen and heard all carriers are having data issues with galaxy s10 with a majority of cases coming from sprint. I've also read comments on websites where users from other countries are having data loss issues.
I have an unlocked S10+ on Verizon and haven't had any connectivity issues at all. (knock knock). I haven't had any of the issues noted in this thread. (Connectivity and data loss) The ONLY thing that irks me is that I cannot access the diagnostic dialer codes on an unlocked phone. I've worked with the local Verizon store as well as Verizon 2nd Tier CS over the phone. No one can explain how or why Verizon has blocked access. (It doesn't even work in safe mode with the SIM out and having wiped the system partition cache). Mods here havn't been able to help either.
Again, as far as connectivity goes... no drops at all and reception is clear with VOLTE, 3G, and WiFi calling. I haven't been to areas with 1G yet so I can't testify to that quality.
